What 49 owners told NHTSA about the 2024 Buick Envista

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.

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.
