2024 Buick Envista

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)

Sunroof glass shattered on I-5 south approx 1215pm just before the Nisqually exit. We looked for cause of the incident but could not find debris/rocks that could've been the cause. Also, there wasn't much glass inside the car, the remnants puckered upwards. The glass shatter seemed to come out of the blue; weather was grey but no rain or sprinkles at the time. We pulled over at the next exit which was Nisqually to look at the damage and to tape up the car.

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.

On December 3rd I contacted roberts-Robertson Chevrolet in Excelsior springs where I purchased my brand new 2024 buick envista. I told them my engine light is on, we scheduled service for 4 days later, the engine light shut off, i contacted them on the 13th telling them it is back on and now i am concerned if it is safe, while speaking to the representative will not share her name, until I am contacted, the service representative, I asked her yestersay at 1 pm cst over the phone if I was safe to be driving my kids to places with the engine light back on or should we be worried. She exact words stated your safe to keep driving, she said if anything. It might not start right away after driving and turning it off. But thats the most it will do. Not even two hours later, im driving my car and its 14 degrees, the car shakes, and I get an emergency shut off immediately nowessage on the screen. As soon as I got pulled over, the place it happened, all my oil just rapidly leaked out. I was told by my someone who works there to light a fire to my car so if the dealership doesnt stand behind it. At least id have an insurance claim. I clearly did not listen to that illegal advice. I am beyond upset. My kids are scared to death when it comes to getting back in the car. I had to pay 200 dollars to get it towed. And now im car less. It is our only car. I am stuck in a situation right before the holidays and I feel [XXX]. I feel complete dealership neglect when it comes to her reassuring my car was okay to drive when she didnt know what the safety risk was. My name is [XXX], I havent had the car for even two years. And its at 6 1 or 62 thousand miles. Im praying for good will or that they are able to fix this and allow me a rental car. I have been stressed to the max. I've spoke to 8005217300 the company who towed us and they told me some [XXX]. I just feel like this is a major safety and major concern issue. My car is garage parked. There was no sign leaks.

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

I filed and submitted my paragraph yesterday and have not heard a word. My son was in the back seat when it happened and he is extremely traumatized in getting back into a vehicle. My car was purchased in 2023 and it is a 2024 and is non drivable due to the engine explosion while driving in 14 degree weather on a two lane high way with my 6 and 7 year old in the back seat. My engine exploded and I no longer have my brand new car I was once so happy about. I hope this is reviewed and someone takes this seriously. I didnt have my brand new car for even 2 years and now I am just out of an option. My car is at the dealer ship and im praying I get good will out of this. I cpuld have been hit on the high way, traffic on coming while I had to merge off the highway as lastly as I could when I felt the explosion.

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

See attached document for complaint.

Needed to jack up the car to change the tire. There is a Jack included with the car. Upon using it in the correct spot in accordance with the owners manual, the Jack began to significantly bend while trying to raise the car to change the tire! It looked so unsafe that we abandoned the tire change. If I were on the side of the road, trying to use this, it could be deadly.

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 DASHBOARD keeps changing while driving, and the dealer states they have fixed it. I have had 2 dashboards replaced since I purchased the car (1 year) and this unsafe while driving my GPS keeps changing while driving. This is VERY UNSAFE! The SUNROOF WILL NOT CLOSE, until the next day. It rains inside my car because it will not close, so I can not use my sunroof PERIOD. This is one of the reasons I purchased the car. NOW, my CHECK ENGINE LIGHT is on for EMISSIONS SYSTEM (IT IS CRITICAL THAT YOU TAKE CARE OF THIS PROMPTLY TO MAINTAIN SAFETY). The dealer held my car for 3 days, and now they state "they requested the part, but no one told them (from the manufacture) that the part is not available due to problems with the current part and they have to rebuild the part, and it's on back order". Now, I'm riding around with a check engine light on until Nobody knows when! I don't trust this dealer, who told me its okay to drive like this AND we will call you when the part comes in. They stated they fixed my dashboard and its still not fixed. They don't know when, they will have the part for my sunroof or my emissions issue, and my dashboard is still not working and I have to borrow someone car to travel because my GPS and Engine light is on. A brand new car and it has been in the shop (6 times) more than any car I have owned. I pay my car not on time and I keep my car serviced, but this not fair to me and I need help please.

SUNROOF will not close, and yes, it is available for inspection upon request. Hard to drive because of the pouring down rain, and unable to close sunroof. I have called the dealership and was asked to bring it in for inspection, but the next morning it closed without problem. 2 days later it did the exact same thing. I waited 1 before opening again and when I tried to close the sunroof, it would NOT close again, until the next day. Now, I do not open it all. I have NOT had it inspected by anyone since it looked at the first time. No, warning lamps or messages prior or after since this has started.

The brake lights for this vehicle are located low in the bumper, not in the main taillights, posing a safety hazard. Because the brake lights are not located where other drivers naturally expect to see brake lights, the risk of a reared collision are unnecessarily increased.

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.

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.
