The required back up camera got water inside the housing, worked for a little while, and then ultimately failed. There is a Recall for other trailblazers with this exact issue, however it seems my VIN was not included in said recall.

The vehicle spontaneously caught on fire, I don't understand why. The person driving the car was in the vehicle when it caught on fire. There was no warning, no concerns.

When accelerating forward, the front wheel is almost locked up, and I was violently thrown forward into the seat belt and steering wheel. The transmission seemed like it jammed and the car was bucking. there is a known GM technical service bulletin on this, but no recall. The car was towed to the dealer and not drivable. Iâm glad this did not happen on the highway or with other cars around or it would have caused an accident and injury.

The 2024 Trailblazer developed a problem going into reverse at less than 17500 miles in December of 2025 when my daughter came home for Christmas. It would slam into reverse or freeze and then shift harshly. The selling dealer replaced the valve body in the transmission while it was in for normal service, the valve body was on order for 30 days in January. After I delivered the car back to my daughter on January 26, 2026 which was 4 hours away in Northern Virginia the transmission continued to freeze and slam into reverse. The selling dealer advised not to drive it back to Virginia Beach, VA. The car was then dropped off at an Arlington, VA dealer and was there for 9 days. The servicing…

My 2024 trailblazer lt's engine light came on about a month ago. I took it to a local dealership and they said it was caused by CCND. Diagnosed code P0128 in pass/fail status. They test drove it to get light to come on and it was unable to duplicate it. They cleared the codes. A month later it came back on. I took it to my dealership and they said they have to take the entire front end off to replace the engine coolant bypass valve. They said that the electronic component was going bad. This car isn't even 2 yrs old. This should not be happening.
