Pontiac G8 Problems

The Check Engine Light With Code: P0011, P0014, P0021, P0024, P0341, P0346, P0336, and/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.

Pontiac G8 Recalls

Front Seat Belt Mountings May Break

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.

Ignition Key Cylinder Turns Off Engine Unintentionally

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.

Under Certain Conditions, the Front Passenger Airbag Does Not Meet Federal Safety Standards

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.
