2024 Buick Envision problems

“After coming to a stop, I then put onto another road and several warning lights chimes came on in my car, including brake system failure. This is the second time this has happened in less than two weeks. A dealership said they fix the problem and then it did it again today I was traveling on a road with several other vehicles. Due to the braking issue, it took me a longer distance than should’ve taken to get my vehicle to come to a complete stop. My speed limit is limited in my car, which could also cause a danger due to the roads that I travel frequently.”

“The contact owns a 2024 Buick Envision. The contact stated that while driving 15-20 MPH, the brake pedal was depressed and the brakes failed to respond as needed, causing the vehicle to crash into a residence. The contact shifted into reverse(R), and the vehicle crashed into a porta-potty at a construction site. The vehicle shifted into park and stopped. The contact stated that the Driver Assist feature was operational during the failure. The contact sustained bruising and soreness to the right side of the body. The vehicle was drivable after the failure. The approximate failure mileage was 22,000.”

“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 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.”

“The contact owns a 2024 Buick Envision. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed and became stuck under the floor liner. The contact depressed the brake pedal to stop the vehicle however, the vehicle failed stop as needed. The contact pressed the park button and turned the vehicle off. The contact stated that the engine was smoking. The contact and her husband then exited the vehicle. The contact stated that it was a very scary moment due to the failure. The contact inspected the vehicle and confirmed that the accelerator pedal was stuck under the floor liner. The vehicle was towed to the dealer where it was diagnosed with a defective floor liner. The dealer informed the contact that the floor liner needed to be replaced. In addition, the contact was informed that the repair was covered under recall NHTSA Campaign Number: 24E066000 (Vehicle Speed Control, Equipment). The manufacturer was not made aware of the failure. The failure mileage was approximately 400.”

“The vehicle experiences a notched (hitching), sticky resistance at dead-center when driving over 55 MPH. It requires noticeable physical effort to break past the sticking point to both the left and right, causing jerky micro-corrections. Please check for any available reprograms or flashes for the Power Steering Control Module (PSCM), and check the electronic torque sensor calibration or replacement of steering rack and pinion. This is a safety issue.”
