Vehicles with certain V6 engines may illuminate the Check Engine Light one or more of the following codes: P0011, P0014, P0021, P0024, P0341, P0346, P0336, or P0391. Our technicians tell us that some vehicles may require a powertrain control module (PCM) software update to correct this issue. Other vehicles may have excess camshaft end play on one or both cylinder heads which will need to be corrected using special procedures outlined by GM.

My brake lights come on when I am driving the car, and the brake lights go off when I press on the brake pedal.

I have replaced the 15amp fuses in the fuse box and moved the relays around. I believe it is a loos connection but having the horns below the headlights on the front fascia means I have to remove the front bumper to even get at them. Also hear audible clicks from he fuse box when horn should sound.

The cables that attach the front driver's and passenger's seat belts to the vehicle may bend and break over time. Dealers will relocate and replace the seat belt tensioner assembly free of charge to resolve the concern.

The ignition key may be unintentionally bumped from the run position to the off position, resulting in shutting off the engine. Dealers will modify the flip key and transmitter assembly free of charge to correct the problem.

With the front passenger seat occupied and in the full forward position, the seat position sensor will cause a 30 millisecond deployment delay between the first and second stages of the dual-stage frontal passenger airbag. In the event of a crash, this delay may result in increased head injury to certain front seat occupants. Dealers will reprogram the airbag control module software to correct this concern.

I have a 2008 G8 GT and it has been absolutely a perfect car!! The nearly 400 horsepower is such a pleasure to have available, and the chassis/suspension is SOOO silky-smoothe... like NO OTHER CAR I've ever driven in my life!! I've driven Lexuses, BMW's, Mercedes and more..... but I have NEVER driven another car that has the same feelings of stability, control, not to mention the 400 horsepow...
