2024 Buick Envista

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

On four separate occasions now, while driving, the vehicle has completely shutdown. Two times this has happened in a parking lot and was relatively safe when it happened, but the other two times have been while driving on the freeway at freeway speeds. On all occasions, the entire dash will flicker a couple times, while the engine will sputter and then shut off. When this happens ALL systems including brakes, dashboard, engine, and steering are completely inoperable. Twice this has happened on the freeway while moving at freeway speeds. Thankfully, on neither occasion did any accidents or injuries occur, but it could very well have been fatal. On all occasions, the car will remain off and cannot be started again by pushing the ignition button for a period of about 20 to 30 seconds, during which time I cannot steer or stop the vehicle. After about 20 to 30 seconds, the car will turn back on and appear to function normally.
