:banghead:2005 Grand Prix GT - Recently my airbag light has been coming on, but goes off if I turn quite sharp. At first the light would come on whenever I turned to the left, but since then it varies. With all the potholes everywhere, it has come on or gone out if I hit the odd one! Can anybody help so I won't have to dump a bunch of money at the local stealership!

Possible clock spring issue. The clock spring passes any signals to the lower part of the steering column from the airbag, any steering wheel controls and horn since the steering wheel rotates.

I agree with BNaylor.
Here's a couple of links to help you understand the issue better
Good Luck
The clockspring is a ribbon wire that is coiled up inside the steering column. This component is the subject of many discussions on these threads. Many times the steering wheel or column is disconnected and then rotated beyond the center position it is required to be in. This will cause the clockspring wire to break. The clockspring delivers current to all of the systems above it… the airbag, cruise control and horn. When it fails (and they do a lot) the wire breaks leaving one or all of the circuits open and inoperative. This will cause the airbag light to come on and shut down the airbag system. As long as that light is on, the airbags will NOT deploy, even in an accident. Sometimes it’s intermittent as the wire begins to break. Once it breaks completely, the ‘airbag’ light will illuminate.
This was a factory recall for many vehicles and many customers are unaware of that.
