2026 Chevrolet Trailblazer Problems

I was stopped at a red light and when the light turned green to go, the car stalled. Steering wheel locked and I had to turn the car off and back on in the middle of traffic. This happened twice in one day to me. I brought it to the dealership and they cannot find a fix for this. The car also stalled on the service manager on the expressway.

Engine shuts off while in drive but stopped- three times, twice at stop lights and once in a drive thru.

The contact owns a 2026 Chevrolet Trailblazer. The contact stated that while driving between 45 and 60 MPH, the air bag and safety restraint warning lights unexpectedly illuminated. After the warning lights illuminated, the steering felt loose, and the brake pedal locked, slid, and then released when engaged. The contact also stated that an electrical failure occurred. The vehicle was taken to the dealer; however, the failure was not diagnosed or repaired. The vehicle was scheduled to be diagnosed by the dealer for a second time. The contact noted that the vehicle had previously been repaired for a separate electrical failure. The failure mileage was approximately 20,000.

I experienced a Hard Stall at a Red Light. The Auto Start/Stop Feature was engaged. The Console displayed "Press Brake Pedal to Start". I had to shift into Neutral and manually restart the Vehicle. I had the Vehicle checked at my Dealer and there were No Error Codes Thrown and the Dealer Service Department could not recreate the Stall.

My new vehicle was stuck in park the dealership replaced a control module then a gear shift assembly and now some kind of brake switch and im nervous that the vehicles is unsafe. The dealership has not been letting me know much I've had to call and they won't give me any paperwork.

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.

Three 225/60 R17 tires bubbled in the sidewall and blew out causing loss of control. Two occurred on the same day another a few weeks earlier. The dot above is on the one remaining tire. This occurred on a brand new car purchased 2.5 months earlier from Bale Chevrolet. The dealer has been of no help what so ever. I had to tow and purchase new tires X 3
