Deaths

A complaint is an unverified account by the person who filed it, not a finding of fault. One complaint is one ODI number, which is how NHTSA counts them.

A recall is the manufacturer conceding a defect, and the repair is free. Whether one covers your particular car is a question only its VIN can answer, because a campaign covers a production range rather than a model year.

Red marks a system with a recall campaign against it. One complaint can name several systems, so these add up to more than 33.

When the complaints arrived

By the year NHTSA received them

By the year NHTSA received them, which is not the year the failures happened. They peaked in 2025 at 14.

This is the year the complaint was filed, not the year the failure happened. The range runs from 2024 to 2026, the last of them a part year, which is why its column is drawn faint.

Crash test ratings

NHTSA New Car Assessment Program

NHTSA crashes a car into a barrier and a pole and measures what happens to the dummies inside. This is what it awarded the 2024 Chevrolet TRAILBLAZER, and it is a separate question from what owners report going wrong later.

Overall
Frontal crash

A rating belongs to a tested body style and drivetrain, not to the model as a whole, which is why more than one is listed. A dash means NHTSA did not rate that test for this vehicle.

LANE DEPARTURE: ASSIST

crash · towed

I was stopped at a red light. When the light turned green I entered the intersection, the LKA system began alerting me and pulling the vehicle towards the oncoming left traffic turn lane. I took my foot off the accelerator and reached over to shut the LKA off as it was pulling my vehicle. The incident resulted in distracting me resulting in my car hitting a car in the oncoming left turn lane.

ELECTRICAL SYSTEM

crash

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, once we got the vehicle back a similar instance happed again, except just the dash info system and

POWER TRAIN

crash

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 and hit another vehicle. No damage was done to the other vehicle or mine, and the gentleman was

POWER TRAIN
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

ENGINE
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.

EXTERIOR LIGHTING
Unit used as a rental from Avis. Night time driving will cause on-coming traffic to flash high beams while my lights are in low beam mode. This is a daily problem with a multitude of on-coming drivers as the LED headlights are perceived to be extra bright / blinding.

If this is your car and a dealer keeps failing to fix it, your state's lemon law may require the manufacturer to replace it or buy it back. How many repair attempts it takes, and how long you have to file, is set by the state you bought in and by nothing on this page.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
