2004 Nav System Problems-any suggestions

I have a 2004 Denali with the nav option. I have had constant problems with the nav restarting itself. The local dealer is clueless on how to fix the problem. I've had the unit sent in once already, but the nav system continues to reset itself while driving. Has anyone else had this problem or know of any fixes?
Thanks

I hadn't heard about this one - when you say it's resetting itself, is it the deck (i.e. entire display) or just the mapping portion? If it's the former, it sounds like they need to reblast the firmware on the deck. If it's the latter, maybe there's a loose antenna connection? Good luck...

What happens is after you start the car, the nav systems shows a white display with GMC in red on it. That's basically the starting screen. Then, as I am driving the nav system will revert back to the white display again, and again, and again. Then, ti acts normal for a while, and then repeats the start display.

How clueless does the dealer need to be? With a sophisticated electronic component such as the nav unit, if they can't figure out fairly quickly what's wrong with it, they should just go ahead and swap it out w/ another unit--or did they already do that and you're still getting the same problem? I mean, if they don't know what's causing the problem, what the heck are they waiting for? Your warranty to expire so that they can then tell you "tough luck, you'll need a new one--it goes for about $2400"?

Is it just the nav display that gets reset--i.e., does the display reset if the screen is displaying just radio or CD info?

I have a 2004 Denali XL with the same problem. Per my dealership, there is a TSB out on the issue and GM is aware of the problem. The nav system constantly resets or locks up. When it locks up, it displays japanese characters on the screen and then won't play CD's, no audio from the rear seat entertainment system, no radio, and obviously no nav display. You can't even turn the system on or off when it's at this stage. Basically you have to restart the car and sometimes that won't even work. I am in contact with GM customer service as we speak and I have already informed them that they need to come up with a solution because I paid the extra money for the Denali over a Suburban of Yukon XL because it was the only "XL" GM suv with factory nav. Of course the Escalade ESV had it but that was even more money. The nav system is essentially useless and renders you stranded several times per trip if you want to make stops to eat or detours while en route.

I have dealt with this issue for approximately 1 year (bought my car in Jan of '04) and have taken it in several times to "prove to them" that there is something wrong. it's one of those stupid intermittent things that the dealership "can not duplicate". They gave the car back to me saying that there was nothing wrong with it. Finally the service supervisor was able to get into contact with GM and they found a TSB out on it. Now I am trying to get the nav system replaced with an '05 unit but they are telling me that they are having the same problems with the '05 units. I find this hard to believe as the '05 unit is supposed to be the same Denso unit as found in nav equipped Toyotas. The Toyota nav system is absolutely flawless. I know this because I have a '05 Toyota Solara SLE with factory nav. The display is the same but the buttons and dials are in slightly different places.

Anyways, I will keep you guys posted but in the mean time if anyone has an '05 touchscreen nav system let me know if you have had any problems with it. Same unit in Cadillacs from what I understand.

hey, I have that same problem.
the smucky dealer replaced the radio 3 times. it got better for awhile, but now it's happening again.
glad to know I'm not the only one !!!

it's like the radio is losing power, then restarting again.
all without losing audio.
very distracting at night time.

I guess I've been lucky so far...have had mine for a year w/ no problems.

does anyone have the TSB # on this issue??
it is annoying as h@ll !!

thanks !

I have an 05 I just picked up two weeks ago. My deck is doing the same thing.

please take it back to the dealer, and tell him you visited an internet forum and it seems to be a common problem. Then let us know what it is !!!!

my dealer keeps replacing the radio, and it doesn't help........
in fact, they gave me a used radio that had more wear on the buttons.
so I'm not happy.
don't let them replace your radio !!

I have an 05 I just picked up two weeks ago. My deck is doing the same thing.

Your '05 with touchscreen nav is doing the same thing? By same thing do you mean resetting or locking up? Mine almost always resets when I try to go to memory points. Mine also completely locks up and displays Japanese characters in the center of the screen. How about you guys. I am still in contact with GM regarding this matter and the official word right now is that we have to wait because there is a problem with the software and they do not have an anticipated date for a software update.

Any of you guys interested in a class action suit?

This is the way that I see it. GM commissioned a usabilty report from Carnegie Mellon University. They outlined 11 catastrophic failures in the user interface and 25 other problem areas. None of those were addressed and the nav system was released anyways. I think it took a new user something like 60+ minutes to enter a destination, a detour, and a memory point. Now, there are all these problems that GM is well aware of but there is no solution. I don't know about you guys, but I have had 2 Suburbans in the past a 99 and an 01 and I bought my '04 Denali XL because the Denali and the Escalade were the only two GM products with factory integrated nav available. I paid a $10,000 premium to go upscale and get the nav but the nav is a real POS. GM is telling us that yes, it's been a year but you still have to wait??????


What do you guys think.... any attorneys out there, anybody know any attorneys out there. It seems like a fairly straightforward issue. Nav advertised, nav doesn't work when it needs to, no solution to nav problem.


If you have had problems with your nav system and you are simply lurking and reading this thread. Post a message so I have an idea of how many users this affects.


Thanks

It locked up right at delivery. It sits there and tries to reset itself. You can not control volume, channel or anything, it just goes on it's own trying to reset. If you had the volume up loud, you are kinda screwed because it will cut in and out and in and out until it resets. Nothing you can do except pull over and restart the truck a few times to manually reset it.

Like I said, I have only had the truck a few weeks. I want to drive it a bit more and see if there are any other issues to tackle when I bring it in.

I will report what happens.

the dealer should be shot right there. Every dealer has a new car department, and they are suppose to go over the truck to make sure everything works. I used to work in the new car prep department, and I drove every car, and thoughly checked out every car before delivery.

I would have not taken delivery, but I have 4 other cars to drive. You may not have that option.

The service department did look at it. what they found was the kid that washed the Denali put a rap CD into the unit. Once it reset, they were able to eject it. They could not tell if it was the cause or not, but it was working. I drove it home, and went a week before it started wigging out again.

PS- the kid got fired for that one. Too bad, as it had nothing to do looking back.

Well, I finally received a response from GM's customer relationship manager. I formally requested that he replace my unit with the newer model instead of replacing it with the same model. Regardless, his response is despite the fact that I have dealt with the issue for a year and the whole audio/ent/nav system renders itself useless when it locks up, they will not authorize a replacement at this time. That means that they have made no efforts whatsoever to solve or fix the problem. All they have done at this point is acknowledge that GM is aware of the problem and is working on a fix. To make matters worse, there is no anticipated date or time frame for a fix.

The most insulting thing is that after receipt of this email, he will not email me back or return any of my calls. I have been very friendly with him and told him how much I appreciated him calling me on the one occasion that I spoke with him. In other words, he has no reason to feel that I am being demanding nor have I been a pain in the butt customer to deal with.

The email response is as follows;

"Dear Dr. XXXX,

Good afternoon. Thank you for your patience. I contacted the Factory Representative to inquire about the possibility of replacing the current navigation system for your vehicle to a newer version. The Factory Representative declined the replacement since GM Engineering is aware of the navigation system concern and a bulletin from Technical Assistance advises dealerships not to attempt any repairs until a repair is available. At this time Technical Assistance has advised that the navigation system concern is a software related concern and not a hardware related concern. I apologize, but there is no estimated time for when a repair will be available.

If you should need to contact us in the future, simply reply to this message or call our GMC Customer Assistance Center at 1-800-462-8782. Customer Relationship Managers are available Monday through Friday from 8:00 a.m. to 11:00 p.m., Eastern Time. Please refer to service request number 1-2965XXXXX for all future communication.

Again, thank you for contacting GMC.

Sincerely,


Christopher Simfukwe
Customer Relationship Manager
GMC Customer Assistance Center"

How's that for a response?

So basically GM is saying that since they can't fix it (for now), they won't...and it sucks to be you but we don't care that you paid (roughly) $2K for the nav option 'cuz we already got your money...

I guess you could sue them but I reckon it wouldn't be worth the time and effort, let alone finding someone willing to take your case over a depreciated $2K nav unit...

I think it would make for a great class action suit, especially since they are still making the nav system available as an option despite the fact that they know there is a problem with no solution. There have to be a lot of people in the class considering how many people have nav systems in Denalis, Escalades and Hummers. Just need someone to represent the class. I would be in.... not for the money but to let GM know that this is not an acceptable response. Seems to me that the fair response to a sitation like this is offer to refund the price of the nav system (replace the unit with a standard Bose headunit with XM) and allow us to install our own after market nav systems.

Demand a swap! In 2000 I bought the high end Odyssey with factory Nav. Right before the warranty ran out it started to have occasional reception problems. I took it in but since it worked fine at the dealer, they sent me home with no fix. A year after the warranty period ended the Nav worked only 10% of the time! In retrospect, I should have addressed it over and over until they fixed it under warranty. Damn thing is over $2,500 to replace!

Doing a swap right now is a waste of your time and the dealers. I have a brand new unit, and it does it also. Not often, but it does.

They are working on a fix from the vendor. As long as your issue is documented, I am sure GMC will take care of the problem once they have a fix.

I don't think sueing, yelling, and demanding something that your dealer has no control over is going to solve anything. Just my 2 cents.

Despite the fact that I had been in during my warranty period Honda would not fix it after the 3/36 had expired. I even brought in the work order with language to that affect. I guess it all depends on your relationship with the service department. I agree that making a stink won't get you anywhere. Probably the best thing is to foster a good relationship with the service manager and have that discussion about what happens after the warranty expires.

I haven't raised a stink or yelled at anybody. I took my car in a few times for the nav issue and as most of you are aware... you have to show them the problem for them to believe you. Of course, the nav issue is one of those intermittent things where it does it all the time except for the one time that you are in the dealership's service bay. After three failed attempts to show them and them checking the nav system without finding any problems, one of the service managers finally called GM and found that it is a documented problem that they are aware of.

My issue with the current situation is that I have gone through all of the hoops and hurdles of alerting them to the problem yet they have done absolutely nothing to rectify the situation. Furthermore, it appears that it is a well documented problem that GM is aware of and has been aware of even before I bought my car. It seems to me that they should have pulled defective products off the shelf and should have made the nav system unavailable as an option. Instead, GM continues to market and sell the nav system as a convenience feature in their vehicles without alerting prospective buyers that there is a problem with it. If they had been honest and sold the nav system with a disclaimer that it has a software issue that is being addressed then I would not have a problem with it at all. I would have not gotten the nav system at all if that were the case. I would have installed an aftermarket in dash system.

To add insult to injury, the fact that I am not receiving a return email or phone call from the GM customer service rep is completely unacceptable. I did not hound the guy or even appear remotely upset with him. I have been nothing but pleasant in my dealings with the dealership and GM. Since the last email that I posted, I left him 2 emails and called him once. Still no response. After purchasing 3 high end GM products in the past 6 years, I can definitely say that they have lost me as a customer forever. In fact, I have already cancelled my GM rewards card. To think, I was seriously considering a '05-'06 C6 Z06 over a '05-'06 997 cabriolet.

I posted, some 3-4 months back, about this similar issue. It boots then just locks up. Then after a good 20 minutes or so comes back and has a screen prompt that says DISC error, unable to read.

I dropped by dealer under the idea it may be a bad disc, well they would not give me another one, in fact they would not even let me try another one. They said set up an appointment so they can look at it. I am the loser on the deal. I have to get a rent a car,I have to jockey my schedule around to drop it off for a day but now I am out $40- 50 in rental car fees. I KNOW what that service guy is going to do...He will plug a disc in, confirm what I said, then say Sorry no fix available, will have to call GM tech service. They will want to keep my vehicle until they have it fixed or say you can come get it for now and I will never hear from them again.

I have been a Chevy owner my entire life(Trust me there is a difference). I have bought many. I am also realistic in that things will break. Where I am not understanding is the lousy "after sale" service. I can understand that they cannot just hop through hoops for every person that walks in the door but I am a very competent mechanic and should be given a bit more respect rather than the c**p I get now. I can say that I am also severely dissapointed in the Denali. For $50K it sure does not add up in quality and service.

* Nav problems
* Fuel economy SUCKS. MPG is 13.6 all the time(I have the Denali, Not the XL). I get 17.2mpg in my Crew Cab K3500 Long Bed Dually with a 6.6liter diesel motor. My truck weighs 11,200lbs compared to 6,000lbs for the Denali)
* Center console stereo has LED problems for the station selection
* Dash constantly squeeks

We gave up our Awesome 2000 Benz 430 for this heap as we needed space for 6 and the Benz sat 5....

GM can keep their Denali junk. Sadly my wife still likes it, I want to off it but cannot come up with a good replacement. I have heard the Chevrolet Tahoe LT is very nice. Few have problems with theirs. Hard to believe we thought that NAV would be the ticket only to have it be a joke.

Wheeeew!...Ok Now I have vented....

I had 2 Suburbans a '99 4x4 LT and a '01 4x4 LT and although I can honestly say that the '01 was flawless, the '99 had a fuel gauge problem that the dealership would not fix. It was rather funny thinking about it in hindsight. It would read 3/4 full when I had about 250 miles on the tank which meant it was about 1/4 full. The dealership changed the fuel level sender (obvious culprit) but did not fix the problem. The second time they drained the fuel, measured it and checked the gauge, found that it read faulty and changed the sender again. No improvement. Finally, the service manager talked to me and said that they did what they could do and had no fix for it. Ha.... He said that there was no problem and that it was within specs. They just made attempts to change the sender to make it "more accurate" than it should be. Finally I asked him. Considering that the gauge is reading 3/4 full on a 44 gallon tank and there were about 250 miles on the tank. Would he go on a 100 mile rural drive with no gas stations? He said, no he would fill up. Oh well, it made no no sense... Regardless, I was stuck with using the odometer as my gas gauge.

The thing that bugs me the most about this whole situation is that I traded in my '01 Suburban with only 17k miles on it and bought my '04 Denali XL because of the factory nav system and extra hp over the suburban. '04 Suburbans did not have factory nav as an option.

BTW... my '04 Denali XL had a sticker just under $60k. It has the nav system, rear seat entertainment system, and sunroof.

All I have to say is that even though the Navigator and the Sequoia have smaller cargo areas, I will not be getting another GM product.

There has to be a software solution to the nav problem because the units are made by Denso which supplies the same nav system to Toyota and Lexus. I have the nav system in my '05 Solara and it is flawless. It's just that a software fix to the problem is not high on GM's list of things to do.

Just got back from the dealership. Per GM TS - advised to replace the radio. There is a fix now, but units are backordered.

Just FYI. If I have any problems afterwards, I will post again.

Do you know if they'll replace it with a touchscreen one?

Do you know if they'll replace it with a touchscreen one?

My guess is probably not since it is supposed to be a software upgrade and there were problems with the touchscreen unit as well. The only thing I am worried about now is that when they replace my unit, I might get one that is not in the same condition as mine. My Denali is used only for long family trips so although the car has 11k miles it is absolutely brand new in every way. Someone posted that they got a replacement unit that had worn buttons.

I have a touch screen now, and they said it will be a new unit, not a rebuild.

Hmmm...I'd be curious as to exactly what is included in the software upgrade that is supposed to fix the problem, and exactly what part of the nav is the problem located in?

I guess what I'm trying to get at is this--could this software upgrade fix be something that might be included in say, the version 3.0 of the nav disc? When I loaded my 3.0 nav disc (to replace the relatively outdated 2.0 one) into my nav for the first time, it was performing some "updates" to my unit. Dunno what these "updates" entailed but I reckon it was doing something other than loading maps since subsequent reloads of the same 3.0 disc into my nav unit don't perform the same "update" procedure.

Wouldn't it be nice if the software fix could be delivered via an update found on the 3.0 nav disc (if it does exist on it at all)? You'd get your nav fixed and an updated map disc at the same time!

Hi tonytone,
I don't know this for sure,
my suspicion is that it rebuilt one or more index into the disk stored into memory.
This may include "point of interest" data like restaurants etc.
I would be very surprised that any unit would automatically flash it's firmware by itself.

Does anybody have more info on this?

Take care, Eggert :bananasmi

i understand that you have to have this new navigation system because non of you can read a map but if this is the same unit that is in this riser that works perfectly, maybe just maybe because it is made by the same company as the other one i would blame the supplier. all these parts are made by japs blame them. if dealer cant fix it i would say its the suppliers fault. bitch at the manufacturer of the unit, see if that will get you anywhere. good luck hope you speak jap, or chin, or tywan.
guys dont get me wrong all this new shit works good in all jap cars but not in any american i'ld say your bitch is with the jerks that built the unit. and they arent the dealer they are someone from anouther country who just wants to make an american car look bad.
dump the unit and put in a bose radio at least its made in usa and you can bitch at an american at least if something goes wrong, but it won't

WTF? Is this guy serious or is he on some kind of crack smoking binge.

read it, think about it, then say that

by the way just as a postscript and the tsb's i have a friend who works at a toyota dealer and is sent to school ever 4 to 6 weeks, they dont have as many tsb's because of this, his statement not mine.
but seriously the nav system is made by someone else not gm so try to get somewhere with them. i agree is a screwed up system but gm didn't build it as with most of the parts in most of the american cars built today, thanks nafta and bill clinton, send all these jobs over seas. try to call the manufacturer of the unit maybe they will send you a fix maybe they wont what do you have to loose.
good luck anyway i do hope you get it fixed, i dont care who made it it should work but remember gm didn't build it

You're right--GM didn't build it, but since they're the ones offering it in their vehicles, they do have responsibility to look into the matter, especially if it's under warranty. Consider this analogy--you buy a brand-name car stereo deck from an authorized dealer, who installs it in your vehicle; then a few months later the deck (while still under warranty) starts to malfunction; you take the deck back to the dealer to have him take a look at it, only to be told by the dealer, "hey, why don't you go to the deck manufacturer and have them troubleshoot it--don't be bugging me 'cuz I didn't build it". Or, you buy a brand-new house from a home builder and a few months later you find some problems (e.g., cracked drywall, etc.) and you ask the home builder to come out and fix it and they tell you, "well, WE didn't build your house--various building contractors did, so you should be talking to them instead". Would you take that for an answer? I know I wouldn't--I mean, I didn't buy my house from a bunch of contractors, I bought it from a home builder, so it's their responsibility to see to it that my problem is resolved...meaning, they should be the ones contacting the contractors, not me.

Even if one were to take your advice and talk directly to the manufacturer--more often than not, they will just tell you to tell the person who sold you the device (GM) to contact them, as they (the manufacturer) typically will not deal with the end-user (that being you) since they did not sell the item directly to you.

84fiero123 what is your problem? There is no need to make racist remarks about who built the nav system. And just to let you know I think it was built by an American company, not a foreign one, and even if it was I'm sure they didn't purposely make a faulty NAV system as you suggested. That would be stupid on there part as they would decrease their chance for repeat business from GM.

GMC has a resposibility to fix the NAV problem for the customer because they are the ones who sold the car, and theoretically the manufacturer should step in and take the responsibility for GM and either replace the NAV systems or offer a fix.

i know that i hit a few sore spots, but before you say i'm racist, let me say something, i worked for General Motors, at CPC Framingham, Mass. for over 15 years, and watched all the parts came in for anything electronic with manufacturers from outside of the USA from simple switches to everything else. anything electronic in a GM product is made outside the USA, its called outsourcing, they were the first ones to do this and got no help from the government. now all the computer geeks are getting outsourced to other countrys and now they want help. try and find any electronic equipment (other than Bose) made here. i find it hard to belive that you want to blame GM for a faulty pease of equipment that was made buy someone else. dont get me wrong i agree they should fix it, but they have got to be having a problem with the company that they got the system from. racist i am not, i've worked side by side for 15 years with every race you can name and never have had a problem with any of them, hell my god son is African American. best man at my wedding was Japanese, and my wife is Polish. so dont call me racist. i just dont like the idea that nothing is made in this country anymore. i have spent my entire adult life building things, everything from cars to houses to oil rigs. i am proud of what i do and have done.
but as i said they do need to fix it , but listen to what we used to say about buying a car;
never buy a car built on a monday or a friday or during a labor dispute, or the first model run of any car or truck.
good luck with your navigation system boys wish i could have helped you, REALLY I DO. making things and making them work right is something i love to do.
here is a place i did find on the net to those of you in Virginia that may be able to help you and they do warrenty work. so again if i pissed anyone off my sincerest apologys but i was just telling it like it is.

I'm glad your a little more calm in your latest post, but using racist remarks are not used by most people who are not racist. Using the phrase 'Jap' is the same as using the 'N' word for black people. I'm not sure what part of the country your from but out west intelligent people don't use those words unless they are racist.

You said that your best man at your wedding was Japanese. Have you ever called him a 'Jap'. I don't think so. People who are not racist do not let phrases like that slip out no matter how angry they are or what point they are trying to get across.

ok guys i'm done you want to call me anything you want i just tried to help you with a problem. you wont listen so good luck geting your idiot map fixed.
i dont hold anything against anyone and nether do these men. we are all from new england, and buy the way the only reason i used jap, chin and tywan, is because my spelling sucks. i work with anywone i dont care if they are black, white, red, yellow or purple. as long as they do there job to the best of there ability. i worked on an oil rig welding with an Arab. he and i went into places that no one else could fit because we were the only ones small enuf. i put my life in his hands and he put his in mine, this was just after 9/11 he didnt have a problem working with me and i didnt have a problem working with him. we depended on each other, we put our lives on the line depending thst the other guy would save us if something happend. would you do that? my problem is with corporations sending all our high paying jobs over seas, now if you don't see that happening the i think you all need to pull your heads out of your asses and smell the corporate shit going on in this contry today.
sorry if my lauguge ofended anyone,( and i'm sure it did) but thats the way i feel. even on thet oil rig job the company i worked for wouldn't hire union help in any field, they sent for guys out of canada rather than pay a decent wage to a qualified american. so if i ofend any of u maybe you should look into your own back ground, when was the last time you were 200' ft in the air hanging off the side of anything depending on an arabian, to save you.
as far as Denalix5 goes and why would a company risk loosing future work goes they may not care if they are just one bad egg in the basket, one idividual in a factory making 50 cents a day. why should he or she, they are making shit to begin with.
i bet you guys even buy the sweet shop shirts and blue jeans, just because its cheaper.
by the way the company that makes your navigation system is delphi a former subsidery of GM that has all its manufacturing factorys all over the world.over a hundred in asia. i found that out with one phone call and a quick web search.

by the way this will be my last post on this subject
im done

by the way this will be my last post on this subject
im done

Yes, the units are made by Denso BUT what you don't realize is that the nav units are not identical. The software is proprietary. Which means that GM and Toyota put their own software into the units. I have both the Toyota and the GM units and they are by no means the same. Sure the screen has almost the same icons etc but the menus are very different. The other difference is the lack of support by GM regarding the problem. Your friend is very misinformed regarding the Toyota nav unit. My Toyota nav unit actually had a "recall" that was not actually called a recall but a service bulletin. Toyota actually sent me a letter telling me that I had to take my '05 Solara in because there was a problem with the accuracy of the nav system (a problem that I never noticed or ever caused any problems for me). They flashed new software into the unit and replaced my nav disc with a new one. The whole thing was done while I waited and only took about 10 minutes. Compare this with GM's lack of action on a problem actually affecting all nav system owners and the fact that I still have not officially heard from GM even though they had assured me that they would let me know as soon as a repair was available for the nav unit.

BTW, it's nice that you could express yourself on this board but it has not help anyone in the least bit. I sincerely hope that you are a man of your word and we will not be hearing from you anymore on this thread.

Gentlemen,
it would be nice if we could leave our anger and politics at home and remember that this forum is here for us to be helpful.
GMC is the seller of the cars and therefore the only fixer of problems. This is especially true in a world that has billions of people not living in the US making all sorts of things for all sorts of manufacturers.

My experience with GM dealers on the topic of Delco stereo products is that there is just nothing. No connection. No info. I could not even get a part number for a radio out of them. And Delco does not talk to you, either...
Take care, Eggert :bananasmi

Just got back from the dealership. Per GM TS - advised to replace the radio. There is a fix now, but units are backordered.

Just FYI. If I have any problems afterwards, I will post again.


Any news on the new units? I called my dealership 2 weeks ago and let them know that there was a fix and to put me on the list for the backordered units. I hadn't heard from them so I called today. I was told that they confirmed that the units were not available but could not confirm that there was a fix or an ETA for the units. In other words. We are back to square one, meaning that GM is once again not letting us know any info. We can not confirm or deny that there is a fix. We have no estimated date of repair in the unit. Basically we are no better off than when this thread started. Everyday that passes pisses me off even further. By the time there is a fix, 3 or 4 years will have gone by and I will be ready for another car. What kind of crap is that? I still think class action is the way to go. At the very least to stop GM from marketing and selling the current nav unit.

Look at the GMC site and you will see that Nav is one of the highlighted features of the car. Even GM realizes that nav is a major selling point. This whole situation is just wrong. The fact that they are still marketing and selling the unit is even more wrong.

My new unit was installed oh, I think two weeks ago, and I have over 40 hours now, and no failure. Longer than I went before. It took about a week to get the part.

Wow, I was told that there was no information available and no anticipated date of release on the new part. Could you do me a huge favor and email me the part number or the campaign# if there is one.

Thanks

If you could please post the service bulliten # or the recall fix so I can show it to my dealer. They never heard of this fix.

I talked to GM yesterday and they mentioned that a dealership name would be helpful also. Again, any help would be appreciated. I have been dealing with this for over a year now.

I am on the road now, so I do not have the work order, but the dealer is John Keady in Davenport IA

GM contacted the service manager at John Keady GMC and he said that he would need some more information to look up what exactly was done. If you would be so kind as to email me and provide me with a work order#. I would rather give him a work order # or some anonymous information than ask you for your personal information.

Thanks.... hopefully this will end my 13 month quest for a solution.

Still road running, sorry, but all they did was replace the unit. This is an 05. Not sure if that makes a difference or not.

If you still need the info, I will e-mail you when I get back.

Good luck!
