BUICK Complaints

In my car there is an electrical issue with the radio. Sometimes when I’m backing up and using the camera the lane assistance doesn’t work properly which can cause someone to back into things if they are using it. Also another issue it has is when I’m driving the entire radio and dashboard flicks and the screen goes out which is dangerous when driving because now I’m not sure what my speed level is checking gas levels if your on phone calls it isn’t consistent. I think this is a major safety issue not sure if it’s electrical but the dashboard and screen goes out together randomly and it affects reverse driving and just driving in general.

The vehicle developed an exhaust leak caused by both weld points on the front exhaust pipe breaking. A dealership inspected the vehicle and confirmed that the exhaust welds had failed, creating a hole in the exhaust pipe and triggering a P0420 catalyst efficiency code. The failure occurred at approximately 31,500 miles. The exhaust leak caused increased exhaust noise and emissions warning codes. The dealership recommended replacement of the front exhaust pipe assembly. This appears similar to known failures on the Buick Enclave and Chevrolet Traverse platform where the front exhaust pipe mounting bracket separates from the pipe due to weld failure. GM has issued special coverage adjustments for similar exhaust pipe bracket weld failures on other model years of these vehicles. The failure occurred at relatively low mileage and appears to be a structural weld defect in the exhaust system.

The rear powered liftgate on a 2014 Buick Enclave unexpectedly fell without warning while the vehicle was parked and the liftgate was fully open. The liftgate suddenly closed and struck the operator on the head. There were no warning lights, messages, or prior indications of a malfunction before the incident. The impact caused a concussion that required emergency medical evaluation, including a CT scan and follow-up neurological care. The incident occurred during normal use of the vehicle while loading items into the rear cargo area. The liftgate system has not been repaired and remains available for inspection. The component currently appears to operate normally, and the malfunction has not been reproduced since the incident. No prior symptoms or warnings were observed before the failure. The sudden closure of a powered liftgate presents a safety risk because it can strike occupants standing beneath it, including adults or children loading cargo. The vehicle and liftgate system have not been inspected by a dealership or manufacturer since the incident.

I am reporting the malfunction and separation of the rear window from the cover. This is a safety issue as there is the potential for it to come off while driving and possibly causing an accident. It started small, but has grown to almost 12 inches. I have not yet found anyone who has the capacity (or desire) to fix this. And those that actually want to take on such a project are charging over $5,000! Please help!

The transmission on the vehicle failed. It is available for inspection. The vehicle began jolting, when accelerating from a stop, or when slowing to a stop. Seemed to be slipping out of gear while driving. We reported the incident to the dealership. They said they found nothing wrong. The issue continued, and the check engine light came on, so we returned to the dealer again. This time they found it needed the transmission to be rebuilt. They have had the car at the service center for 5 months. The parts they need are no longer available.

I am reporting a defect involving my **2025 Buick Encore GX AWD manufactured by General Motors. Within two days of purchasing the vehicle, the dashboard displayed the warning message “Service Charging System – Vehicle May Stall.” I contacted the dealership on the third day of ownership and was instructed to bring the vehicle in for service. Since that time the vehicle has required multiple repair visits related to the charging system. Repairs included diagnosis of the electrical charging system, replacement of the alternator, and replacement of wiring harness components related to the charging system. I later learned the alternator had already been replaced prior to my purchase of the vehicle, and it required replacement again after purchase during the repair process. Because the charging system warning appeared almost immediately after purchase, I am concerned the defect may have existed prior to the vehicle being sold. Although the warning message is not currently appearing after the most recent repair, the defect occurred almost immediately after purchase and required repeated service visits. The vehicle still does not appear to operate normally. While driving at a steady highway speed, pressing the accelerator sometimes results in no immediate response. There can be a delay of approximately one to two seconds before the vehicle begins accelerating even when additional pressure is applied to the accelerator pedal. I have also noticed the engine sounds louder than expected while idling. Because the original warning indicated the vehicle may stall and the vehicle continues to demonstrate abnormal acceleration response, I believe this may represent a potential safety concern. I sought resolution with the manufacturer, however the manufacturer has not accepted responsibility for the condition. I am submitting this complaint so the issue is documented in case other owners experience similar charging system or acceleration problems.

The contact's friend owns a 2026 Buick Envista. The contact stated that while driving 5 MPH into a parking lot, the vehicle stopped unexpectedly. The contact stated that the vehicle jolted as if the vehicle was in a crash. The steering wheel was unresponsive while attempting to turn to the left or the right, and the front wheels failed to respond as intended. After stopping the vehicle, the ABS and stabili-trak warning lights illuminated. The vehicle was towed to a local dealer, where it was diagnosed, and determined that the damage to the steering and front suspension was caused by the vehicle driving over a curb. The contact stated that the driver had not driven over a curb. The vehicle was not repaired. The vehicle was towed to a collision center, and it was determined that there was a failure with the front suspension and steering. The collision center also concluded that the damage had been the result of the vehicle driving over a curb. The vehicle was not repaired. The manufacturer was informed of the failure and opened a case. The failure mileage was approximately 2,500.

> Failed component is the front sun roof window > The shattering of the glass sounded like a bullet coming through the roof of the car. Sprayed me with glass from the implosion. I was in heavy rush hour traffic. >There are several complaints about the sun roof window just shattering. > Not at this time. >No warning or cracks in the sun roof were observed. > I was driving on the Highway at 60 mph and the front sun roof window just shattered and sprayed me with glass.

The contact owns a 2021 Buick Encore GX. The contact stated that while attempting to park the vehicle, the message to “Shift to Park” was displayed while the vehicle was already shifted in park(P). The contact stated that several attempts to shift to park were needed to clear the message. On several occasions, the contact drove the vehicle and then shifted back to park(P) for the message to be cleared. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 58,000.

1)Numerous Gas Cap ‘red warnings’ were fixed each time 2)Driver-side ‘Seat Belt’. Fixed. 3)Check engine light ‘off and on’ will quit after 5-10 minutes 4)Stabilitrak/Traction-control (red light warnings), on and off, finally stayed on: Took back to Parsons of Antigo, WI dealership for repair; they said it was fixed. I left dealership at their closing time, started car, the car was shaking, called dealership/told them what was happening/they said bring it back on Monday—this was a Thursday evening after 6 PM! a. I had to drive this ‘shaking-car’ home approximately 35 miles away, while going about 30-40 mph/in a shaking car, seems car wanted to stop. Very frightening in the dark night. b.I had a wrecker come and take the car back to dealership. I do not care to deal with dealership after this—I changed to different dealership. c.About 3 years ago, while driving on US 8 outside of Rhinelander the car just ‘simply’ went off the highway; I quickly managed to bring the car back onto the highway blacktop. Is this for real? i.Until July 2025 I worked 40 hours/week and I believed and trusted that the repair services would inform me that I needed to beware of ‘this or that’; when usual car maintenance was completed. d.In 2019, going through a ‘Traffic Circle’ in Green Bay, WI area; this vehicle just would not stop (as I need to wait for cars coming from the left) and somehow, I made it through that circle without hitting another car or damaging this car! The police officer asked, ‘What happened?’ and I told him, ‘I have no idea what happened’. I was given a ticket for $175; that was mailed with a check before a certain date. i.Now, after reading all the ‘recalls and complaints’ I can understand ‘the why’ I had to endure driving with this vehicle’s unreliable mechanisms” throughout these years. 5)2021 Air bag ‘red light’ for Service recall Airbag/serviced. 2-19-2026 airbag another warning to replace again. PeopIe say this car looks like new. A 'lemon' buy
