2009 Buick Enclave Problems

Transmission Fault and/or Check Engine Light With Code P0716, P0776, P0717, P0777, P2714, P2715, and/or P02723

Vehicles with a 6speed automatic transmission may develop one or more of the following faults related to a broken 35R clutch wave plate inside the transmission: Illumination of the Check Engine Light with code P0716, P0776, P0717, P0777, P2714, P2715, and/or P02723, loss of reverse gear, slipping or harsh 3rd or 5th gear shift. Removal and dis-assembly of the transmission will be required to replace the broken 35R wave plate. It is also extremely important that all debris from the failed part be cleaned from the transmission while it is disassembled in order to try and prevent future problems.

The Check Engine Light With Code: P0011, P0014, P0021, P0024, P0341, P0346, P0336, and/or P0391

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.

Hesitation under load and high speed

Under normal driving, the engine hesitate and around 65 to 75. It also hesitates when going up hills. Under load condition.

2009 Buick Enclave Recalls

Liftgate Falls Closed Without Warning

The power liftgate may fall suddenly from the open position due to the failure of the struts that support it when open. Dealers will update the software for the liftgate actuator motor control unit to prevent rapid closing of the liftgate free of charge to resolve the problem.

Front Seatbelt Buckle Failure

In the affected vehicles, there is a flexible steel steel cable that connects the seatbelt buckle to the front seat frame. Over time the cable may fatigue and separate. If the steel cable separates, the seatbelt may not properly restrain the seat occupant, increasing the risk of an injury in a crash. Dealers will inspect and replace the affected seatbelt buckles (lap pretensioners) to correct this concern.

The Side Impact Airbag System May Not Deploy As Expected

Increased resistance in the front seat mounted side impact air bag (SIAB) wiring harness can result in the SIAB and seat belt pretensioners not deploying as expected in the event of a crash, increasing the risk of personal injury. Dealers will replace the affected harness connections with soldered connections to correct this concern.
