2026 Chevrolet Traverse Electrical Problems

2nd time losing brakes in my vehicle. 1st time dash board lit up with multiple icons and display message board states message “ Brake Assistance Failure, Press Hard To Brake, Speed Limited”. Luckily I was turning on a street and was able to pull over. Towed to the dealership where it was purchased. Basically they said it was a computer issue and they reset it and I should be go to go. 2nd time… same thing however the rear view mirror blacked out and then the dashboard lite up with the same icons, same message “Brake Assistance Failure, Press Hard To Slow, Limited Speed”. Also came on message board “Service ESC” and “Service Traction Control”. Unfortunately this time I was on a major highway doing 65-70. Almost creating a huge accident, I was able to pull over on the left of traffic and called immediately call emergency number for DPS to assist. Also called Chevy dealership to get a tow setup. This happened tonight Nov. 9th, currently are is at the dealership waiting for diagnostic tomorrow. I can’t express the safety issue this is. Losing brakes is a serious matter that needs attention immediately.

The blind spot warning sensor goes off at random. Making the driver not know if an object is close to the vehicle. This is very dangerous as a driver because you can get used to it going off and getting comfortable with nothing being in your blindspot, even with the warning light on. What happens when there actually is something in your blindspot? As you can see in the picture below, there is nothing in the mirror and the blindspot warning light is on. It has been this was since it came off the lot at the dealership. We have been told there is no fix for it. We would like to see a recall for this particular sensor before it becomes a problem.

On start-up, intermittently the center display freezes, the HVAC system defaults to 76 degrees with the a/c and defrost stuck on with the blower on high. No driver input possible through the center display. Condition may clear by itself or not even through several shut downs. Numerous DTC's set. Always a CEL. For me, 2x dealer (repairs). They reprogram controllers. Condition not corrected. Possible HMI and/or HVAC controller hardware problem. Dealer doesn't know how to fix. Casual internet search indicates many identical complaints. Concern is, HVAC control is a basic function that should function correctly. Driving in the winter with no heat and a fogged windshield is a safety issue. GM is aware of the problem and has no fix.

While driving on the freeway, the vehicle’s battery shut down. I received the following text as this happened, so there was no way I could react in a timely manner as to exercise safety and any precautions: “Diagnostic Alert: Low 12V battery detected in your vehicle. To recharge, try and start in a well-ventilated area. If it won't turn on, try to jump start or call 1-888-4-ONSTAR. Text STOP to cancel.” This situation was life-threatening and scary. I was scared for my life.

I’m reaching out for help with a frustrating situation. I purchased a brand new 2026 Chevrolet Traverse in New York, but after moving to Texas, I'm having trouble registering it. The car can't pass the state inspection due to emissions issues, and local dealerships aren't providing any assistance. The only advice I've received is to drive it around for a bit, hoping the problem resolves itself. However, I'm concerned about the safety of myself and my 4 children, and it seems like Chevrolet isn't taking this issue seriously. What steps can I take to resolve this situation?
