BUICK Complaints

While driving on the highway there was a random harsh jerk on my car, and I was immediately unable to maintain safe speeds driving nearly causing a serious crash. All of the service lights (Service Parking Assist, Service Power Steering, Service StabiliTrak, and Check Engine Light) should up on the dashboard. Trying to engage the vehicle into drive after parked had a harsh jerk shifting into gear and the accelerator was not working properly (going extremely slower than applied pressure). Mobile mechanic reader coded my vehicle with U0101 “Lost Communication with TCM”. After touching that TCM connection all of the service lights randomly turned back off, and the vehicle drove (temporarily) normal. No repairs were performed due to possible recall concerns.

Fuel pump relay is overheating to dangerously high temperatures. At least 211 F degrees. Causes the fuel pump fuse to melt leaving me stranded. Immediate replacement of the 20 AMP fuse is necessary to get the car running again. The fuel pump relay gets really hot even if the AC is not on. Waited for hour and a half in near 100 F degree heat for a tow truck to it home. I’m lucky the car did not catch on fire. I know quite a few of the Buick Lucerne’s have had recalls regarding this item. Picture of the actual car is included. No police report was necessary as this was a breakdown situation. This has utterly disrupted my life because I do not have access to a car with good air conditioning until this problem is repaired.

The contact owns a 2020 Buick Enclave. The vehicle was reversed out of the driveway; however, after shifting into drive(D) and depressing the accelerator pedal, the vehicle jerked, vibrated, and the check engine warning light and other unknown warning lights illuminated. After several minutes, the vehicle functioned as intended. A short distance later, the failure reoccurred. The vehicle was taken to Auto Zone, but no cause for the failure was found. The vehicle was taken to a private dealer where it was diagnosed and determined that the catalytic converter was clogged, and that the electronic brake control center module and the transmission module had failed. The vehicle was not repaired. The contact stated that the failure persisted. The manufacturer was not made aware of the failure. The failure mileage was unknown.

The contact owns a 2025 Buick Envista. The contact stated that while driving during heavy rain, the windshield wiper fractured in half, resulting in poor visibility while driving. The vehicle was taken to an independent mechanic, but the part to repair the vehicle was unavailable. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 15,266.

Onstar keeps running and failed. Nothing works on car without it. Its dead after shutting it off. And no safety features work.

Shifter to park message showing on dash and Vehicle will not stop beeping and drains the battery and you can not lock the car. This is a know problem with Buick Encore 2023 and Buick has not recalled it and did not cover the cost of the repair, which cost me $659.68 plus tax.

Brakes are extremely noisy at low speeds. Dealer advice that this is normal When driving at low speeds brakes squeak extremely loud This is clearly a defect that GM needs to address They keep using the excuse that is the the high quality pads that they are using

SUV has ran hot and had it towed on 3 separate occasions when this happened. Had thermostat and water pump replaced. Not fixed. Coolant keeps running out if bottom of suv. It is at dealership and blown head gasket and probably much worse. Apparently these models have something wrong with cooling system. The engine cost will be about what I owe on it. Buick needs to pay for another engine for my SUV. I have a warranty but they won’t honor the engine replacement and I’m out of a vehicle.

I am writing to formally report a serious mechanical failure involving my vehicle and to request further review and assistance. While operating my vehicle, it unexpectedly stalled in the middle of an intersection, creating a significant safety hazard. At the time of the incident, the check engine light illuminated and the RPMs surged to a range between 6 and 8. I was able to safely move the vehicle to the side of the road, place it in park, and have it towed to a dealership for inspection. Following their evaluation, I was informed that the transmission requires replacement. I have since become aware of a recall related to transmission issues; however, I was advised by a Buick representative that my VIN is not included in the recall. Given that my vehicle is experiencing the same or a substantially similar failure, this determination raises concerns and warrants further review. I have consistently adhered to all recommended maintenance schedules and have taken proper care of my vehicle. Based on the circumstances, I respectfully request a thorough reassessment of my case, including reconsideration for coverage or assistance with the necessary repairs. I appreciate your prompt attention to this matter and look forward to your response.

My 2025 Buick Encore GX has experienced an ongoing failure of the rear backup camera system. The issue began intermittently in February 2026, and earlier this month (March) it has progressively worsened. The camera now does not function at all. When shifting into reverse, the display often shows a black screen with a “camera unavailable” warning message. On some occasions, the camera briefly functions but displays severe distortion, including abnormal colors, flickering, and warning symbols overlaid on the image. The issue continues to occur intermittently and unpredictably. This failure creates a safety concern because the backup camera is a required safety feature intended to assist with rear visibility while reversing. The malfunction reduces visibility and increases the risk of not seeing objects, vehicles, or pedestrians behind the vehicle. The problem has not yet been inspected by the dealership due to limited appointment availability. I have documented the issue with photos and video showing the malfunction, including distortion and loss of image. Approximately 8 weeks after purchasing this vehicle in March 2025 (5/3/25) the Digital Instrument Cluster (driver information center) and infotainment display went completely black while driving, leaving no visible speed, fuel level, or other critical vehicle information visible to the driver. This raises concern about the reliability of the vehicle’s electronic systems, particularly as the backup camera— another critical safety feature— is now also malfunctioning. This issue has progressed from intermittent to consistent failure.
