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.

SERVICE BRAKES, ELECTRICAL SYSTEM, ENGINE
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.

SERVICE BRAKES
Event happened on January 19th 2026. I’ve had my brand new car for 10 days and on the morning of the 10th day I started it to see multiple warnings. The car was in park and had not yet moved that day and a “Service Stabilitrak” came up. Once I started moving 2 more alerts came up “Break system failure, 62MPH top speed” and “Service power steering”. I brought it to the dealer and they diagnosed it with a Master Break Cylinder failure. The car has 120 miles on it. And due to the part being on back order I’ve been without that new car for over 3 weeks now.
