| Engine And Engine Cooling problems |
The contact owns a 2026 Chevrolet Trailblazer. The contact stated that while driving at various speeds, the vehicle failed to properly shift into gear while the gear shift lever was in use. The check engine and another unknown warning light were illuminated. The vehicle was towed to a local dealer, where several undisclosed fault codes were cleared. The vehicle was towed back to the same local dealer, where it remained for further investigation. The contact was informed that the transmission might need to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 100.
My brand new two week old 2026 Chevrolet Trailblazer LS issue: auto start/stop system failure, the engine shuts off and does not restart description:? while stopped at traffic lights with the auto start/stop feature engaged, the engine shuts off as designed. However, when I release the brake pedal, the engine does not restart as it should. Instead, the vehicle displays a message stating “press brake to start,” and the vehicle behaves as if it has been completely turned off. This leaves the vehicle temporarily disabled in traffic and unable to move immediately when the light changes. I must press the brake and manually restart the vehicle, causing a delay and creating a safety concern, especially in intersections. This issue has occurred multiple times and appears to be related to a malfunction in the auto start/stop system. The failure to automatically restart the engine creates a risk of being stranded in active traffic and increases the likelihood of a collision. No warning lights or prior indications are given before the failure occurs. Concern:? this is a safety issue for me and my family because the vehicle does not respond as expected when attempting to accelerate from a stop and leaves me stuck in traffic unexpectedly. It is now in the shop for the second time, as I was able to record this continuous malfunction of my brand new 2026 Chevrolet Trailblazer. I get anxiety everytime I drive it. I feel I’m going to be rear ending or be involved in some type of crash. The vehicle is currently not safe to drive currently at the dealership for a second time. I had it towed each time, as I feared for my life and safety. Dealership could not duplicate issue. They asked me to record it and I was able to.
