2022 Chevrolet Trailblazer: check engine light

Filed Sep 18, 2026 · Engine · CA

When entering onto the freeway, I accelerated to the speed of the freeway traffic and the turbo system failed and the message was ENGINE POWER REDUCED and the check engine light came on. During the time of the turbo failure, I was almost hit by another vehicle that had to suddenly brake to avoid hitting me. This turbo failure happens frequently.

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.

The check engine light and other error codes are on. The vehicle would run fine and then the engine would go into 1/2 power and go slow while driving. This has happened other times too. It has been in the shop and the dealership and GM do not know what is wrong with it. It has been there for almost 2 weeks.
