2023 Chevrolet Trailblazer Engine Problems

The bolts holding the exhaust to the catalytic converter broke while I was driving my car. The car could have flipped, the exhaust could have busted through the vehicle, or I could have caused an accident and died. This comes on the heels of the EXACT SAME THING happening to my wife's Chevy Trailblazer with nearly the same mileage as mine. I have 97K miles and she 96K. This is a KNOWN ISSUE to them and it is NOT THE FIRST time this has occurred. There are thousands of similar instances that have occurred and one can easily find the anecdotes through an online search.

Had p1098 code come up on car at 67000 issue coolant control valve assembly went bad. This a commons issue with trailblazers and other cars similar to it. Bad design cause extremely expensive repair for this component.

Coolant Vavle malfunction Engine could overheat Yes Manufacturer No warning lights..check engine light came and I had the car diagnosed

The turbo went out on the car for absolutely no reason. Message popped up on dash board saying "Engine power reduced". I have seen this happen to many many many other card across the country. It does not many how many miles are on the car. some Ive seen 25k and some ive seen at 60k. Shouldn't Chevy be recalling and fixing the part? Seems unfair to me as a consumer. Who has thousands of dollars to get that repaired?

at around 42,000 miles my Trailblazer displayed a message that engine power had been reduced and the check engine light came on. I took it to my dealer who diagnosed as a problem with the engine turbo fixed it and returned the car to me. I drove for 2 weeks and the same thing happened. I traded it in on an Equinox after the service manager said the turbo was a know issued. I did not want to be driving on the interstate with reduced power. Also I took a financial hit on the trade.
