I should have filed a complaint here after the catastrophic failure. The next time I may not be so lucky and it could cause loss of life. I was driving at approx. 65 MPH on the frwy when bang! An explosion under my hood that caused my car to jump over a lane, I slammed on the breaks, swerved but couldn't push the brake pedal down anymore. It felt hard and would barely move. i had no way to slowdown or stop! And traffic infront of me was slowing fast. I put all my weight on that pedal even tried pumping it, but it would only move alittle. Luckily the car in front sped up just enough for me to swerve onto the shoulder. As I slowed i could depress pedal alittle if I stood up on it out of my seat but stopping distance was like 15ft while maybe going 15 mph. This all happened in a matter of minutes i still dont know how I was able to avoid an accident. The engine sounded really rough. So I called the dealership they said to bring the car in. I had already spoke. With them that week due to traction control system and transmission causing instability and brake issues. I was mortified when I found out what happened I had cracked 2 pistons & the force was so strong it blew thru the membrane that seperates the break system, got oil in my break lines! This is a new car! Dealership said it was a known issue & GM determinedtitle was a design flaw. I had 2 pistons replaced and my break system flushed my car has never been the same. There's always something little and intermitten still with the transmission & Now the engine jumps while idling and stopped in drive it jumps so hard the car jumps fwd, feels like ill hit whats in front of me. I lost significant value at only 26,290 miles, i cant afford to trade it in on disability, covid turned into long haul covid, no affordable extended warranty. I have no piece of mind in a car I dont feel safe in. What happens when the pistons fail they didnt fix. How many injuries or lives must be sacrificed before they do something.
