Take it back to the dealer, GM has a basic warranty on repairs.

He said he took it to the dealer to be scanned, then to HIS mechanic to be repaired.
They aren't going to warranty a code scan  

Sounds like there might be a wiring problem or something else going on. A code scan will point you in the direction of the problem, not fix it. Most of the time, it's a hard part or sensor that the code is pointing to. The rest of the time isn't so easy. That's why most shops charge a 1 hour diagnosis fee on trouble lights (SES, ABS, SRS , etc).

Maybe go back to the dealer, pay them an hour, and have it diagnosed? Although, if you do that, then have your mechanic repair it, and it fails again, you'd still be up shits creek on a warranty.....

Could be a faulty sensor again? It's happened before.
