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

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.

Was driving car and attempted to roll my window door and the car would not allow it. Then I started hearing clicking noises which was the sound of locking and unlocking door. Which I heard in succession of at 9 times. Later on the return drive on the highway the car let me consistently lock and unlock when in drive. I got home, turn the car off and radio did not turn of even after opening driver’s door

To whom it may concern, I am writing to formally file a complaint regarding the safety and reliability of my leased vehicle. I have been experiencing ongoing issues that pose a serious safety risk. Approximately two months into my lease, I began experiencing electrical problems with the vehicle. The most concerning issue is the car's tendency to shut down unexpectedly while driving, which has escalated over time. Each incident has resulted in significant concern for my safety and that of my passengers, as well as for other drivers on the road. I visited the dealership to report the problem and get the car serviced but I was unfortunately met with unprofessional behavior, and was asked to leave the dealership without resolution. Despite my repeated attempts to address the ongoing issues, I have been unable to find a suitable solution. Additionally, the lack of available loaner vehicles has made it increasingly difficult to have the vehicle serviced. Driving a vehicle that is prone to unexpected shutdowns is not only inconvenient but poses a significant safety hazard. I am deeply concerned that continued use of this vehicle may lead to an accident, endangering myself, my family, and others on the road. Given the seriousness of these safety issues, I am formally requesting an investigation into these matters. I believe it is essential for this situation to be addressed promptly to ensure that necessary measures are taken to prevent accidents and protect consumers. Please let me know if further information is required to support my complaint. I appreciate your attention to this serious matter and look forward to your prompt response. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2024 Buick Envista. The contact stated that while driving at various speeds, the instrument panel displayed a blank screen; however, two seconds later, the instrument panel operated as intended. The check engine warning light was illuminated. The failure occurred several times. The vehicle was taken to the dealer, where it was diagnosed, and determined that the body control module needed to be replaced. The contact related the failure to NHTSA Campaign Number: 23V744000 (ELECTRICAL SYSTEM); however, the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 36,109.

I was driving and while trying to put on brakes and stop I couldn't . I noticed that the Antilock Braking System light came on along with other lights. I almost hit a car because I could not stop. I was very frantic and scared. I could have hurt someone including myself. I am still shaken by this. I called roadside service and they towed it to Suntrup Buick in St. Peters Mo. After the car was delivered to them they called me 30 minutes later saying "no lights are on". I told them I have onstar and if they would like I can send them the alert they sent on my app. The alert is still there which says "Schedule service now". Braking system requires your attention now". I also have snapshots of the warning notice. I don't want a vehicle that has brake issues ..this could have cost me my life.

The contact owns a 2024 Buick Envista. The contact stated that while at a stoplight, the vehicle shut off unintendedly. Additionally, while driving at an undisclosed speed and accelerating, the vehicle stalled. The contact stated that the instrument cluster screen was blank. There were no warning lights illuminated. The vehicle was towed to the local dealer, and the contact was informed that there were no trouble codes retrieved. The vehicle was not diagnosed or repaired. The manufacturer was contacted and suggested to the contact that the vehicle be traded. The failure mileage was approximately 7,000.

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.

The instrument panel intermittently blacks out while driving. I have taken it back to the dealer twice and they are unable to reproduce the issue. The first time, they said it was a software issue and ran an update, but that did not fix the problem. I found online that this is a known issue so I contacted Buick Customer Care. They checked my VIN and said there are no recalls on my car at this time. How can I get my car on the recall list? This is very disturbing and I do not intend to drive the car until this can be rectified. Please help!
