2024 Buick Envision

The master brake cylinder failed. not once but twice. It is available for inspection at the dealership currently. I lost the ability to be able to stop my car and use my brakes. Luckily I did not hit anyone elses car as I had to pull off the freeway. This is a major safety and liability concern. Yes, the problem has been confirmed by the dealer. The vehicle has not yet been inspected by a GM engineer yet for the 2nd time it happend. No, the only watning signs that came on was when the failure was occuring.

Driving and open areas or in town car will automatically break. Multiple times over 45 miles an hour and lock up the brakes then accelerate car has been in and out of the dealership 7 to 10 times1 time for 10 months straight. Vehicle collision lights have come on for side rear and front collisions when brakes lock up and then accelerate we videoed and taken pictures showing no cars surrounding during instances. The last lockup cause injuries to my son and my wife’s neck. They are seeking medical attention today.

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.

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.

When driving on the freeway at night in intermittently foggy conditions, I attempted to adjust the automatic high-beam controls on the center console screen in the vehicle. During this attempt, as I was selecting to deactivate the auto lighting function, ALL of the vehicle lights shut off at once, and the console and screen-based instrument cluster went completely black. I attempted to stop the vehicle as quickly as possible and struck a small reflector post at the side of the road. The instrument panel and lights restarted, but his incident could have easily resulted in a catastrophic loss of control, endangering myself and others. To my knowledge, no incidents or recalls of this sort have been reported for this model, but a recall for a similar malfunction was issued in late 2023 for some models of the Chevrolet Trax, Buick Envista, and Buick Encore GX. This vehicle has not yet been inspected by the manufacturer, police, insurance representatives, or others as of yet, but an insurance claim has been issued, so such an inspection may be forthcoming. No warning lamps or warning signals preceded this complete blackout of all the vehicle's lights and the main screen/instrument cluster. This malfunction appeared without warning and, in this case, during extremely dangerous, nighttime driving conditions.
