“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 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.”
“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.”
“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. I’m glad this did not happen on the highway or with other cars around or it would have caused an accident and injury.”
