Buick Envista Problems — All Years, Common Issues & Reliability

See attached document for complaint.

My son's car was hit by this Buick while he was making a right turn. The driver of the Buick was not paying attention and thought he had already turned. She accelerated into him and AEB did not prevent it. We are not sure why this Buick's ADAS failed. It is not our car, but that of the person who hit us. I don't know the answers to the above question as we were not the driver and it is not our car. Our concern is how could the car allow such an impact to occur especially at low speed. Video from our car showing the accident is here: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 inspection, coverage, or resolution as soon as possible. Thank you for your prompt attention to this matter

Window will not go back up. Also when the windows are Locked ( Light indicator on) THEY STILL GO DOWN. My driver window was half way down and would not go back up. The Fuse was checked and Did not need to be replaced. Approximately 6 hours later window went back up.. WEIRD

Passenger window will go down while LOCKED. Strange noise from front cabin

The vehicle’s infotainment/display screen (center touchscreen system) malfunctions. The screen flickers, freezes, becomes unresponsive, and frequently fails to connect. The malfunction creates a safety concern because the screen controls critical functions such as navigation, rear-view camera display, Bluetooth/phone connectivity, and vehicle settings. When the screen freezes or flickers, I am unable to safely access navigation or hands-free phone features, causing distraction while driving and increasing the risk of an accident. The issue has occurred repeatedly during normal vehicle operation. There were no warning lamps prior to the malfunction. Symptoms include screen flickering, freezing, delayed response, and loss of connectivity. These symptoms began intermittently and have progressively become more frequent over time.

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. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Answer: The vehicle has been inspected by a Buick dealership. General Motors Customer Assistance has been contacted regarding the issue. No police report was filed, as no collision occurred Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Answer: There were no warning lamps, messages, or symptoms prior to the incident. Warning messages and indicator lights appeared at the time of the failure, including brake system warnings, Stabilitrak, and steering assist reduced.
