The 2024CHEVROLETTRAILBLAZER carries 47 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 7 crashes, 0 fires, 0 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 5/5 front crash, 5/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2024 TRAILBLAZER is electrical system with 10 filings, followed by engine (9) and power train (6). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 2 investigation files overlapping the 2024 TRAILBLAZER. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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.
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.
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.
Check engine light came on steady (not flashing) took to local repair shop and was informed it was a Thermo Control Valve. My car currently has approximately 66k miles on it.

My 2024 Chevrolet Trailblazer has two main issues. First, there is a constant squealing noise when braking. I reported this twice to the dealer â 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 couldnât afford. This problem started before the vehicle reached 36,000 miles. Second, the electrical system malfunctions occasionally while driving. When I connect my sonâs phone to Bluetooth, both the dashboard and infotainment screens shut off completely for a few seconds. This happens while the vehicle is in motion, and it is extremely dangerous, especially on highways. The screens then turn back on. I believe both issues may relate to safety and should be investigated.

When shifting from park to drive after the engine start none of the gears on the shifter engage. All positions are in neutral except for park. When shifting from park to any gear the engine revs when the throttle is pressed but the vehicle will immediately roll whichever way the ground is inclined. The power brakes won't engage thus forcing the driver to put their entire weight on the brake pedal to stop the car. A fix for this issue is described in General Motors Service update N2424466290 which identifies solution as replacement of the clutch piston housing. The Dealer will not fix the problem because my VIN # was not on their list of vehicles to fix. This is a safety issue because it happens randomly and surprises the Driver when the car suddenly starts coasting in whatever direction the ground is sloping. In my case the car suddenly rolled into a lane of traffic backwards in a Costco parking lot. Fortunately no cars were coming as I struggled to apply enough force to the br

I received a email from carfax stateing the truck had diagnostic testing and is the transmission in the engine system. Itâll start up but you cannot drive it. It shows that are passed the state inspection on June 27/2025 stating that the truck passed the inspection how the truck went past inspection and itâs not driveable and I donât have it. Thereâs no way thatâs fraud you gonna say that the truck pass inspection when you canât drive it normally when you go get a state inspection and once they do it and it pass they give you the keys and put the sticker on it. In this case the truck is still at the dealer and itâs not driveable. You canât drive it. Itâll start up. They change the oil rotated to tires but itâs not driveable. You canât drive it.

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 nice and said it caused no damage for either of us but my car cannot keep doing this. Sometime is not right with it to be constantly jolting forward as soon as I shift to drive and take my foot off the break peddle to go. This could have been a lot worse had a human been in front of me and I do not wan
