Same as in the other two complaints. At one year and approximately 5000 miles I personally did the first oil change. Car was approximately 3 quarts low on oil after draining the oil for the oil change. Filled up to manufacturers recommendation. Two months later and approximately 1000 miles on the car, the car was 1 quart low. GM has a bulletin on this very issue bulletin number 01–0 6–0 1–011N. Started oil consumption test through the dealer. Dealer stated the first remedy is replacement of a valve, followed by another consumption test. Next option is replacing the engine.

The contact owns a 2024 Buick Envision. The contact stated that while in reverse(R), the vehicle started rolling backwards and independently stopped. There was no warning light illuminated. The vehicle was taken to a local dealer, where an employee suggested disabling the parking brake. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 2,000.

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.

“Loss of vehicle stability” “Feels like wheels may detach” “Ride height abnormal” “Unresolved after multiple repairs” “Safety risk”

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.
