Buick Enclave door locks problems

Filed Oct 31, 2026 · Electrical · FL

I am reporting three unexpected vehicle behaviors that raise safety concerns. While stopped at a red light with the transmission in Drive and my foot remaining on the brake pedal, the vehicle suddenly lurched forward. I had not released the brake. On another occasion, after I had parked and turned the vehicle off, the driver’s power seat moved all the way backward and the seatback reclined all the way down without my intentionally activating those adjustments. Afterward, while the vehicle was still off, the doors repeatedly locked and unlocked without anyone touching the controls. I am concerned about unexpected vehicle movement and uncommanded operation of the seat and door locks. I request that the federal safety agency review these incidents for a possible safety defect.

The rear liftgate locking mechanism failed to latch causing cargo to exit the vehicle where the car behind this car smashed into the cargo causing an accident. For whatever reason the rear door will not lock at all. The fuse was perfectly fine, appears the actuator is defective. No warning was given because the rear liftgate was open and unlatched. After realizing the gate would not close it would notify it was open but the power liftgate operates just fine, and when you activate it, it will push the gate closed and not give a warning until maybe you hit a bump in the road.

Went to get out of the vehicle from driver side and the door wouldnt open. You can pull the door handle back but door will not open. Door will open from the outside. Also, the passenger side air bag notification comes on for a while but then will go off periodically. When you start the vehicle it will say "service air bag" (picture attached).

Vehicle was purchased used in 2010. First had problem while sitting still at a red light. Alarm bell rings stating stabilitrak traction contorl service, power door locks and unlock, speedometer moves out of control. When we try to drive power is slow and engine pulls hard, check engine light comes on. We took it to dealer and they kept it for a couple of days but could find nothing wrong. This happens every 3 to 4 months sometimes longer. When vehicle is turned off it seems to reset itself. This seems to be a gm problem as I have looked online and found several other vehicles all having the same problem with there never being a fix for it. This always happens when sitting still with foot on break at redlights in the city. [xxx]. These are just a couple of sites where people have stated the same problem all gm vehicles.

Sitting in car with engine running and in park the dashboard lights starts blinking and the auto door locks starts locking and unlocking by themselves. It doesn't happen all the time just once in a while.
