2024 Buick Envista problems

“My 2024 Buick Envista experienced catastrophic engine failure at 42,000 miles, requiring an engine replacement on Feb 11, 2026, after a rod failed and caused severe internal damage. Around 50,000 miles, the vehicle began stalling or losing acceleration when coming to a stop, with the check engine light. I have also experienced “Service Power Steering” and “Service Theft Deterrent” warnings and an incident involving the steering wheel locking. Restarting the vehicle several times the vehicle resets it self and works These problems create serious safety risks, including losing acceleration in traffic, being unable to maneuver safely, and potentially losing steering control. The vehicle has been taken to a dealership multiple times, but the intermittent issues have not been reproduced or conclusively diagnosed. The dealership initially mentioned battery corrosion and later a weak battery. General Motors has been notified of the situation.”

“It was in the shop 9/19/24 for the screen going blank while driving causing a safety concern as was unable to tell how fast was going, screen slowly came back on and they found had internal fault and replaced telematics control module. All was fine until July 2026. Picked up from Glen Polk GM in Gainesville Texas 7/15/26 they state reprogramed radio, and USB file. The screen went out 7/19, 7/21, 7/29. 7/31 we dropped car back to dealership 7/31 and they kept it until 8/4/26. This time they state the repair performed reconfiguration update as they claim the previous update was corrupted. Today 8/14/2026 the screen blanked out again at 7:10am. I now have a new appointment for 8/19/26 at 10am. I have also opened a corporate complaint with GM.”

“What component or system failed or malfunctioned, and is it available for inspection upon request? Answer: The brake system failed, specifically involving the brake master cylinder and/or electronic brake booster assembly. The vehicle and affected components are currently available for inspection at a Buick dealership. How was your safety or the safety of others put at risk? Answer: The vehicle experienced a complete loss of braking while in motion. The brake pedal did not provide normal stopping capability, and the vehicle did not slow or stop as expected when the brakes were applied. This created an unsafe driving condition due to the inability to stop the vehicle using normal braking input. Has the problem been reproduced or confirmed by a dealer or independent service center? Answer: Yes. The vehicle was inspected by a Buick dealership following the incident, and the dealer confirmed a failure of the brake master cylinder and/or electronic brake booster assembly.

“I am writing to report a serious and ongoing safety issue with my vehicle. While I was actively driving in traffic, my car suddenly shut off completely without warning. This occurred while the vehicle was in motion, creating an immediate and dangerous situation. During this incident, the steering wheel locked up multiple times while I was driving, making it extremely difficult to control the vehicle and safely maneuver through traffic. This put not only my safety at risk, but also the safety of other drivers on the road. In addition to this, there are multiple mechanical and safety-related issues with the vehicle: •The driver’s seat is stuck and cannot be adjusted. •The front doors will not lock. •The back doors will not unlock. These issues significantly increase the risk of injury or harm in the event of an emergency, accident, or even while the vehicle is parked. Given that the vehicle shut off in traffic and experienced steering lock while driving, I do not feel the car is safe to operate. I am requesting that this matter be reviewed urgently, as this vehicle presents a serious safety hazard to myself and others. Please advise on the next steps for…”

“The data screen for navigation has gone blank several times. A few times previously but 3 times in the past 2 days. The speedometer is viable but not the radio or navigation. Adaptive cruise control has occasionally alerted that it is not available & shuts off on its own. An alert yesterday stated power steering needs to be serviced but nothing is wrong. The car has turned off as I started to pull out into traffic & turned back on its self 3 times today. One time in the morning on my way to the gym at a stop light when it turned green when I went to proceed the car turned off and turn back on its self, leaving the gym pulling out of the parking lot pulling out into traffic it turned off & back on by itself & this evening after stoping at a store I stopped at the exit & when I went to pull out in traffic the car turned off & back on again by itself. Also the delay wipers do not come on themselves.”
