Some Buick Enclave owners report experiencing issues such as a flashing traction light, engine misfires, and oxygen sensor problems. These symptoms often indicate a loss of traction, which can be triggered by engine misfires or faults in the ABS wheel sensor. Additionally, engine misfires can lead to a loss of power and cause the check engine light to illuminate intermittently. Oxygen sensor issues may disrupt the air-fuel mixture combustion, further contributing to engine misfires and triggering the check engine light. Some owners also note a jerking sensation while driving, which may be related to the engine misfire or traction control system problems. Furthermore, a malfunction in the traction control system, potentially caused by faulty wheel speed sensors or low tire pressure, could result in the traction control light and check engine light activating simultaneously. It is essential for owners to address these issues promptly to prevent further damage to their Buick Enclave and to seek professional help for accurate diagnosis and repair.

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 apowertrain 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.
