2024 Buick Envista

Vehicle has stalled when moving slowly and making a turn or slight turn. In all cases, the engine shuts off, all displays (instrument cluster and infotainment display) go black, and power accessories such as windows, radio, ac are all off. No warnings or service lights have appeared in the instrument cluster. July 4, 2026, morning – Vehicle stalled entering an alley, moving slowly and turning. This occurrence did not involve stopping previously to the stall as the next two did. In this instance the engine started again on its own and power came back on, though ac settings were changed. July 4, 2026, afternoon – Vehicle stalled after stopping for cross traffic in a roundabout and then moving to enter the roundabout. It was necessary to completely stop the vehicle in traffic order to restart it (depressing brake pedal and pushing the start button). August 8, 2026, morning - Vehicle stalled after stopping at a stop light and then moving to enter the intersection and turning. It was necessary to completely stop the vehicle in traffic order to restart it (depressing brake pedal and pushing the start button). We have taken the vehicle to two different GM Service Centers to diagnose and resolve the issue. In both cases the service centers were unable to determine the cause, being unable to duplicate the situation. I enclose the service reports for both - Hallady Motors, Cheyenne, Wy 7/10/20236, and Tyrrell Chevrolet, Cheynne, WY 8/17/2026.

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.

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.

Engine began smoking on freeway while driving in rural gap between metro cities. Then a sound like driving over a 2 liter bottle occurred. After I pulled over, there was smoke coming out the coolant reservoir. The coolant reservoir was empty! It's using 1/3 gallon prediluted daily. Last summer the air conditioning compressor failed while driving 75mph in a rural gap between metro cities. I was in a rental for 2 months before the backordered part arrived. Please investigate all aspects of the cooling system? Vehicle has 10k miles.
