Consumer Description

The bolts attaching my muffler to my exhaust pipe sheared off of my 30,000 mile 2022 chevy trailblazer at highway speed, launching them into my muffler. My exhaust pipe dropped-at 70 miles an hour it could have ripped off, and I am lucky the bolts went into my muffler and not something more vital. Also, If the pipe or muffler had fallen, I-or someone behind me- could have run over it causing potential control issues. I am seeing that this is a common problem on various consumer forums. There was NO warning- didn't even get a check engine light after the fact- things just got REALLY loud. I was fortunate to be close to an exit (as I was in a construction zone) and was able to get a tow to the nearest dealership.
