BUICK Complaints

The vehicle has less than 60,000 miles. Sometimes, when it is shifted into park, the info center states that it is not in park. I have to jiggle the shift or shift it into other gears and go back to park. The shift is definitely in park when this happens.

Transmission would not connect with the engine. La Fontaine dealership in Saint Clair. Said I need a new transmission cost $14,000. It has 59823 miles under the vehicle.

There is a know water leak issues with GM. The below is the tsb, Technical Service Bulletin (TSB #16-NA-073. This is a safety issues because if your not aware it could lead to mold in your car. I noticed my issue about 3 weeks ago when my floor board was flooded. I can tell by how the carpet looks its been leaking for a while. I would like this to be further looked into. This is a know issues and the dealership should be responsible for repairs. This is also going to be a costly repair

The envision started losing power, the engine would not gain speed or if it did it was very slow, had the booster vacuum sensor changed, Sudden loss of power or sluggish acceleration, In the beginning the noise/whining was not loud however increased from the engine. Took to a repair shop, could not figure it out, informed dealership, was advised to bring it in. As the car was driven into the lot it died and was unable to start again, dealership informed it was going to cost more than the $22,000 that I paid for it. It appears that the turbo’s failure has damaged internal components, a full engine rebuild is necessary. Bought the car with 63,000 miles, engine went around 100k, had an easy care insurance/mechanical policy just over the mileage limit, tried contacting Buick, due to no recall they wouldn't start a case file for me

Three nuts snapped, which secure the front muffler to the length of the exhaust system. The engine side of the exhaust pipe became disconnected and dragged along road, which occurred while driving the vehicle on a residential road. Steering was not impacted, however the pipe would have eventually come completely free, without driving directly to an auto-body repair shop.

While driving my brand new 2026 Buick Envista Avenir with only 347 miles on the odometer, the vehicle became difficult to control and multiple warning messages and service lights illuminated simultaneously: “Brake System Failure — Your driving speed is being restricted as braking may be difficult,” “Service Brake Assist — Your vehicle may not brake automatically or assist in braking when it detects a likely collision,” and “Steering Assist is Reduced — Drive with Care.” I pulled over immediately and contacted OnStar who advised the vehicle was unsafe to drive and arranged for a tow. The vehicle was towed to the selling dealer the same day, January 13, 2026, and remained in the dealer’s possession for 31 days for diagnosis and repair, until February 13, 2026. The dealer replaced multiple primary braking components: electronic brake control module (EBCM), brake master cylinder, power brake booster, and reservoir kit. These repairs involved both the vehicle’s electronic control systems and major hydraulic/mechanical brake components. The simultaneous multiple critical warnings, the loss of full brake response/control, the restriction of driving speed, and the reduction of steering assist show that core systems responsible for stopping and vehicle control were compromised. Replacing the EBCM along with major hydraulic components indicates a complex, systemic malfunction. This failure created immediate danger on the road, forced an extended out of service period for a new vehicle, and caused a month long significant disruption and expense. A primary safety system failing at such low mileage raises serious concerns about reliability and the risk of loss of braking performance, which could lead to a crash and endanger vehicle occupants and other road users. Consumers should be aware that a brand-new vehicle with only 347 miles stopped operating safely without cause, under normal driving conditions, and required replacement of major hydraulic/mechanical brake components.

the passenger front sidewall of the tire has a bubble. The tire is a Goodyear LS-2 235/45R18 is the model. I felt very unsafe do drive on a defected tire. The tire dealer told me it was not a defect and i would have to replace the tire at full cost. There was no warning of a problem with the tire. i discovered it after a routine vehicle inspection by myself.

The contact owns a 2020 Buick Enclave. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The vehicle lost motive power and was coasted to the shoulder of the roadway. No warning light was illuminated. The vehicle was towed to the dealer where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was in the process of being repaired. The manufacturer was made aware of the failure, and a case was filed. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 45,684.

2018 Enclave w/106k on the odometer and the catalytic convertor cracked. $2200 repair.

The muffler and tail pipe has fallen off 6 times and ive had to get repaired. I believe it is due to the bad torque converter that others have complained about and goggle says that is a likely failure on the buick.
