Verified

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.

    On two occasions the check engine light has come on suddenly...and remained on. On both occasions, the car was towed to the dealership who advised me that "sometimes computers have to be adjusted." There remains other troubling problems, which may or may not be attributed to this symptom, e.g. car has shut off completely when making hard left turns, car has surged unexpectedly when applying brakes, etc.
