2021 TB Zues Bronze Activ
Wife was driving the TB today and while driving a light came on and ssid Have Chassis serviced. Anyone know what this may be? Seems it went away the next time she restarted the truck.
It was on the NHTSA site. Search for 2021 Chevrolet Trailblazer under recalls and then select the tab for "manufacturer communications". Lots of interesting info there. There are actually several false warnings related to software glitches.How do yo know but not my dealer? ha ha ha
Yes as long as your Trailblazer is still under warranty. Once your warranty runs out they will charge you to fix any TSB related repairs. Recalls are different than TSB's since they are required by law to fix them whether you have a warranty or not.Do dealers have to fix TSB's if my TB has any of the many starting to grow in numbers.
It really depends on the dealership. If your vehicle isn't showing any signs of problems related to the TSB they don't have to fix it. Some will fix it, some won't. They usually need to verify the problem before committing any time and technicians to fixing it.For instance, mine has not done this but would it be looked at otherwise?

If it fails you should get a CEL since it controls the variable valve timing. I'm not sure what happens to the bolt when it fails, but if it was a safety issue a recall would have been issued instead of a TSB.Won't this particular issue become a BIG issue if it failed?
Or you could try to convince the dealership to at least check the bolt to make sure it was installed properly. I've heard of a few people who got the repair done under warranty even without a CEL. It worries me too, but even if that bolt caused engine damage GM is required to fix it or give you a new engine. If my warranty was about to expire I would definitely get them to look at it for peace of mind.Wait for the CEL I guess.
