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.

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 dealer said they could not duplicate the situation and returned the car after 9 days.   My daughter stated that the transmission has continued to act up in reverse with freezing and slaming while trying to reverse in real world settings.  The Trailblazer was dropped off for a 3rd time on Saturday, February 21st and since then we have not heard a word from the dealer.  I called Chevrolet Customer Service and they assigned a case number to the problem with the transmission.  The case number is 89420437 and Sarah at Chevrolet said she would be in contact with my daughter by Sunday, March 1st.

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.
