2026 Chevrolet Traverse Problems

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 August 25, 2026, my 2026 Chevrolet Traverse experienced a severe safety failure involving the Automatic Emergency Braking (AEB) system. While moving slowly forward in a drive-thru lane with no obstacles in front of the vehicle, the car's automated systems unexpectedly and violently slammed on the brakes.The vehicle brought itself to an immediate, harsh stop without any actual hazard present. The sudden, uncommanded application of maximum braking force caused severe physical jolting, resulting in a whiplash injury to my neck.This unexpected braking event creates an immediate crash hazard for vehicles behind me and poses a severe risk of physical injury due to violent, unprompted stops. This incident appears directly related to ongoing electronic brake module and automatic braking system malfunctions under active federal investigation. I request a thorough safety investigation and a formal recall to address this dangerous defect.

Brakes have been squeaking since purchasing the vehicle brand new. Have been told that “this is a known issue but it’s “normal””.

While driving 65mph, the vehicle’s engine shut off, a ‘Reduced Acceleration Drive with Care’ message showed up and I had to coast to the side of the freeway. Engine would not restart and dealer confirmed a piston contacted a valve and a new engine is needed.

This vehicle is unsafe for two reasons. First, it slams you on brakes and puts you in park at random times. Middle of road, parking lots, etc. This puts you at higher risk of someone hitting you. The second thing is when pressing the gas when taking off after a stop, the rpm’s jump up and the engine revs up, but the car is barely going. Not safe when crossing intersections along with many other times. Both of these puts mine and my families safety at risk along with others on the road. No warning signs, lights, etc. Car is in shop for second time. First time on November 28, second time on December the 11. Still no answer on a fix. Just that they think they may know the cause. The dealer has gotten the car to reproduce these issues.

When shifting into drive from start, the shifter does not shift. I have my foot on the brake at the same time also. This has happened at least 8 eight times sense the SUV went over 3500 miles on the odometer. I have to wait about 5 seconds before trying it again. This is a safety item that needs immediate attention by Chevrolet and GM, If I needed to evacuate an area, or my garage in the event of a fire and the shifter fails!!!?? should I take it back to the dealer and ask for a refund?? O give them a chance to fix it?

My car is available for inspection upon request. AWD Service and 4WD Service messages appeared at 389 miles and 2104 miles on the odometer. Messages appeared during operation of the vehicle, shutting down AWD as an option and defaulting to 2WD. Messages would go away and AWD would come back online after a few hours of leaving the car off. AWD system was in use when error messages appeared and deactivation of the AWD/4WD system increased risk during icy road conditions. When taken to the Houston Mac haik Chevy dealership service center, I was refused at the door, stating that the messages needs to be on for them to take a look. No warning lamps or other messages appeared prior to failure. Message first appeared during normal operation with AWD on at 389 miles on the odometer. The components have not been inspected by anyone.

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.

Windshield making creaking noises. Windshield has split down the middle and now continuing off to the side. Dealership states no know recalls and refusal to fix it. No rocks have been hit. Damage is directly down center and all the way to the top.

Brand new car just purchased the end of March 2026. Went through car wash multiple times with no issues until one day the shark fin antenna came off and broke the plastic anchors. Now the circuit board is exposed to weather hazards. I read online multiple times this is an ongoing issue with this specific make and model and still GM declines to cover this under warranty.

The car is equipped with a supercruise feature, which should ideally enhance the driving experience. However, I've encountered a significant issue: even when this feature is not activated, the vehicle tends to oscillate between the lane markers. This problem becomes particularly pronounced under poor road conditions, such as when it's raining. The moisture on the pavement obscures the lane markings, and in these instances, the car automatically drifts toward the right side of the road. As a result, I find myself constantly struggling to maintain control of the steering wheel in an effort to keep the car centered within the lane. When it veers off to the right, I must exert extra effort to correct its direction, which can lead to a hazardous driving situation, regardless of the weather conditions or time of day. The need for constant corrections not only creates frustration but also increases the risk of losing control, making this a serious concern for both my safety and that of other road users.

The weight detection is failing to recognize a child in the passenger seat.
