2012 Buick Enclave electrical 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.

If any warning light comes on such as my add air to a tire (it always tells me the wrong tire), all of the warning lights start flashing. Things shut off (radio, dash lights, backup camera) and sometimes the car will shut completely down and come back on. I am afraid to drive very far.

I had the recall done on my vehicle as part of the 2015/2016 liftgate recall. I have had no problems since. This morning when getting into the back of my car, the liftgate started to close on it's own with no warning (beeping or lights) and hit me on the head. Even though it is supposed to open again when it detects an object in the way, it continued to push close on me. I had to force the liftgate up while it was pushing down. I tried turning the power off and the liftgate won't stay open at all. I tried propping something under it to keep it open, but due to the weight of the liftgate, I cannot keep it open. I effectively can no longer safely use the back of my vehicle for storage, as I am afraid the door will try to close on me every time. I have read that it is an electrical/software issue, as well as an issue with the struts on the door. I had the software upgraded, but the struts were not replaced as part of the original recall. The only electrical issues I've had are that the actuators for my heating & A/C are not switching over. Because of this my defrost and front vents don't work. I live in an area where it is below freezing in the winter. The defrost not working has caused safety issues because the windows will fog up suddenly while I'm driving. I have to pull over often to squeegee the fog off the inside of the windows so I can see while driving. Tried replacing the parts ourselves, and it still doesn't work. I have also had issues with the radio/entertainment system. It randomly changes between band, cd, aux input, satellite radio and USB with no input from me. Although this is more of a nuisance than a safety issue, I fear it points to a larger electrical problem. I have taken my vehicle to a dealership for the actuator and entertainment system problems and was told they can't replicate the issue, so they can't fix it. Does it every time I drive.

When filling up the vehicle with gas, it is flooding the engine... There is also another issue that when you turn off your vehicle and the key is out of the ignition, the car and radio still runs...apparently, there is a fuse box that is causing this problem.
