BUICK Complaints

While driving on the highway at 60 mph, warning on dash came on saying “engine power reduced” and drop down speed to around 25 mph and I could not accelerate more than 25 mph on the highway which could have caused an accident because of the traffic flow behind me. I put a code scanner under the dash and it read code P2138, Throttle pedal position sensor switch.

After two transmission flushes and being told by a Buick dealership's service technicians that nothing is wrong with the vechile's transmission, it has now failed completely at ~90k miles.

Leaking flex pipe on the exhaust causing undue rattling and possible exhaust fumes entering the passenger cabin.

Onstar module out. Car can not be detected of location. Can not use gps. In the event of accident onstar can not help me this is a safety problem for a woman especially. When it first went out the car would not cut completely off had to disconnect battery. The gps light stays on with a line through it. Can’t use blue onstar button it’s completely out. Dealership says module needs to be changed. It has also affected other components of the car. I see this is a wide range problem. Dealer sell this as a safety component in the car but when asked about a recall they now want to state its its luxury.

While driving down the road goin around 45 mph all of a sudden my steering wheel got so stiff I could hardly steer the car off the road and out of traffic. I didn't hit anything, my power steering just stopped. I put the car into park and turned off the ignition after a few minutes I started it back up and my steering was back to normal. This has happened to me 2 times driving my 2016 Buick Lacrosse Sport. It's Dangerous and Honestly if your not paying attention it can cause a accident.

This vehicle has major suspension issues containing the complete strut assembly, lower control arms, and strut yokes/forks, which can not be replaced due to the discontinuance of the vehicle and parts itself. Because of this the car cannot receive an alignment which cause the tires to be eaten up at a rapid rate. When going over a bump in the highway the steering column goes one way while the car goes another. The car slides all over the road. Extreme safety concerns for my family and I.

Car has airbag light on. The car keeps leaking which then caused damage to my spark plugs and coil pack. It then led to the O2 sensors being burned. It has been at the dealership multiple times within a 3-week time frame. The low fuel light comes on when it is on a full tank, then it begins to hesitate and the car lunges forward when at a complete stop. Tires act like they cannot keep traction when all 4 tires are brand new and front rotors and brakes have been replaced. Yes, all my concerns have been brought to many dealerships' attention. It is unsafe and unreliable. The dealership said they could not replicate the issue but once I get back into my car it starts up.

The contact owns a 2013 Buick Regal. The contact stated that while stopped at a stop light and depressing the brake pedal, the hybrid battery would power off as intended; however, when the brake pedal was released, the vehicle would lose automotive power before suddenly independently powering on before jolting. The check engine light illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. In addition, the contact related the failure to NHTSA Campaign: 13V173000 (Electrical System); however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 130,000.

A 2021 Buick Encore GX with 66,828 miles experienced sudden transmission failure while driving. The vehicle lost forward gear engagement and began slipping, creating an immediate safety risk to the driver and other motorists due to unexpected loss of vehicle propulsion and control. The vehicle was diagnosed by an authorized GM dealership. Diagnostic codes P2714 (Transmission Control Solenoid Valve 4 Stuck Off) and P0700 (Transmission Control Module Request) were confirmed. The transmission fluid was found to have a burnt odor indicating severe internal damage. The check engine light was the first warning symptom, followed by slipping and loss of forward gear. General Motors previously issued Technical Service Bulletin 24-NA-009 in March 2024 specifically identifying DTC P2714 on the 2021 Buick Encore GX as a known internal defect affecting model years 2020 through 2024. This bulletin confirms GM was aware of this defect prior to this vehicle's failure. Despite issuing this bulletin, GM has not issued a recall, leaving owners of affected vehicles responsible for repairs caused by a known manufacturer defect.

While in motion at about 25-30 miles per hours, slightly stepping on the brake to slow down, the car just… wouldn’t, I was forced to swerve, preventing damage to cars ahead, I went over a curb
