Buick ENVISION

While driving for approximately 2 1/2 hours with cruise set at 78. I did need to brake on occasion and then resume speed. For no apparent reason the car suddenly braked. Speed dropped to about 50 and then immediately resumed speed. No one was hurt. Things in the back seat pushed forward. I don’t know if it has anything to do with that incident but from them until I returned home, about 1 hour later my windows were fogging, I turned on the defrost about 3 times.

Description of Safety Defect: While operating the vehicle at approximately 25-30MPH and make a right turn, the vehicle experienced a sudden and total loss of power/engine stall, accompanied by a "Check Engine" light and a "Reduced Engine Power" notification. This resulted in a near-collision on a public roadway. The vehicle's steering and braking response were significantly compromised during this event, creating an immediate life-safety hazard for the driver and passengers. Dealer/Manufacturer Response: The vehicle was recently in the possession of McGovern Buick GMC Westborough for service. Despite the vehicle exhibiting an active Check Engine Light (CEL), the dealership staff pressured the consumer to take delivery of the vehicle and drive it on public roads. The service advisor admitted in writing that the CEL was active but insisted the vehicle was "feel free to drive." Furthermore, the dealership attempted to falsify internal corporate safety notes to claim the consumer "insisted" on taking the vehicle, masking a known mechanical defect. This represents a willful suppression of a safety defect by a franchised dealer, which led directly to a hazardous operating condition. Injuries/Crashes: No crash occurred, but a near-miss was documented. Passenger experienced severe emotional distress due to the sudden loss of vehicle control in traffic.

The contact owns a 2025 Buick Envision. The contact stated that upon picking up the vehicle from the dealer a day after purchasing the vehicle, while attempting to start the vehicle, the vehicle failed to start, with several unknown warning lights illuminated. The dealer replaced the battery; however, the failure persisted. The vehicle was taken back to the dealer, where it was determined that the failure was a parasitic battery drain. The contact was informed that the dealer was unable to verify what was the cause of the parasitic battery drain. The contact was informed that the engineer might need to inspect the vehicle. The vehicle was not repaired. In addition, the contact stated that the vehicle had been taken back to the dealer several times because of the failure. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 2,700.

My 2025 Buick Envision with 10,000 miles on it has squeaky brakes. My previous 2023 Envision had the same problem, Brakes check out ok, but squeak persists.

On 12/18/2025 at approximately 5:00 pm, during rush hour traffic, while driving 60 mph on the expressway, my car automatically downshifted to drive1, the engine revved up significantly and the car reduced power and had sluggish acceleration. It did not come out of Drive 1 until I was able to get off the expressway and put the car in park. The car is available for inspection upon request. I was panicking in heavy traffic and cars were honking at me as I could not speed up. I took my car to the dealer but he could not reproduce the exact problem. The vehicle or component has not been inspected by the manufacturer, police, insurance or representatives. There were not any warnings or messages prior to the symptoms. This is the second time this has happened within the eight months that I have leased the car.

The vehicle was taken in for the oil level not registering on the dip stick 5235 miles on the odometer, they said it was 2 quart oils low. They said they would do an oil consumption test and to bringv it back in 2000 miles. We took it back with an odometer reading of 7451 and it was again 2 quarts oils low. There is an oil consumption issue on this vehicle.

Prior to the first oil change which is recommended at 7500 miles, I check the oil and there was NO oil present on the dip stick...none, not a drop. I had to add 1 3/4 quarts to get it in the accepted range. We took the car for its normal 7500 mile oil change and informed the dealer, upon inspection and oil change they said nothing was wrong with the car. About 2000k miles after that oil change I checked the oil again and again it was well over a quart and 1/2 low. I added enough oil to get the oil level into the accepted range. I made an appointment with the dealer and they looked at the car and said it was 3/4 of a quart low upon arrival and want me to start an oil consumption study. My concern is if this car is using that much oil, its a matter of time before engine failure and what if this happens at speed or when I am on the expressway, it feels like a safety concern to me.
