“My daughter was stopped at a stoplight and the auto-stop engaged. The light turned green and she began to accelerate when all of the error lights on the dash lit up, then the dash info system and infotainment system went out followed by the engine turning off and not restarting. While all of this happened, the vehicle behind me struck my daughter’s car. Luckily it was at a low rate of speed and no one was injured. I took the car to the dealer and after nearly a week of testing they found nothing wrong and found no error codes in the system. They ere not able to replicate the problem. However,…”

“My 2024 Chevrolet Trailblazer has two main issues. First, there is a constant squealing noise when braking. I reported this twice to the dealer — the first time they said it was just sand inside the wheel. The noise continued. On the second visit, they told me it would cost over $100 to inspect the brakes because the wheel needed to be removed, which I couldn’t afford. This problem started before the vehicle reached 36,000 miles. Second, the electrical system malfunctions occasionally while driving. When I connect my son’s phone to Bluetooth, both the dashboard and infotainment screens shut…”

“Almost every time I shift from park to drive and take my foot off the brake my car jolts forward a couple feet/inches to take off by itself in a manner that it should not. This has been going on since I got the car brand new and have had it just over a little over a year. I try to be as careful as I can with it and mentioned it to the Chevrolet dealership that does all my maintenance on my car. They are not sure what is causing the issue, but on 05/24/2025 I was attempting to get ready to get gas and needed to pull up slightly a little bit more and when I shifted to drive my car jolted forward…”

“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.”

How we read this (methodology)
How to read this: raw complaint totals are not a clean reliability score — a model year with more cars sold, or simply more years on the road, accumulates more complaints regardless of how good it is. So this page leans on two signals that are not distorted by sales volume: the share of complaints falling on each vehicle system (the breakdown above) and NHTSA's own crash / fire / injury / death flags. When we compare model years of the same model, we normalise by years on the road (complaints ÷ vehicle age) rather than comparing raw totals. Age-normalised, the 2024 Chevrolet Trailblazer draws about 10.7 complaints per year on the road, ranking 4 of 4 among the Chevrolet Trailblazer model years we have ingested (1 = most complaints per year on road).
