Any one have a Sequoia (2004) with a bad smell when picking up speed
with the windows open ?
Only got 5,000 miles and has been doing it since day one.
Brought back to dealer and said normal. ( the fuel we use )
other than that it's great. But the smell is to much.

My 2003 had this. Toyota has a TSB for this and they replaced 2 catalytic converters and reflashed the ECU for free...now no more smell!

Check out this thread on the 4-runners. It seems to be a common occurance.

If the smell is like rotten eggs/hyrdogen sulfide, then there is a free fix. It is replacement of the catalytic converter. There is an extended warranty on it - 8 years I think, but better check that cuz not 100% on # of yrs or if there is a mileage limit, too.
