What owners report
The contact owns a 2025 Chevrolet Traverse. The contact stated that while driving at an undisclosed speed, the Super Cruise or Cruise Control would not deactivate when the On/Off button was depressed, causing the steering wheel to flash red and the vehicle to suddenly shift down in velocity. A message "Super Cruise not available" was displayed on the instrument panel. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 5,000.
8/4/25 Vehicle was pulling from side road to main highway when lights and warnings came on dash cluster. brakes were very soft and not very responsive, car was slowed down on its own. Was able to pull into a driveway and take photos of some of the messages. One said service traction control, one said service ASC, and one said 'brake assist fail, press hard to brake, speed reduced. After restarting car all was normal. 8/11/25. Sitting in some morning traffic and all the same messages came up and brakes were soft again. Was able to keep some distance between myself and other cars until I could get off the road. Immediately made an appointment for dealership service. After restarting car, all was normal again. Took car to dealership at appointed time and they kept it for a week and only did test drives to try and recreate problem. …
This was one of about ten times this has randomly happened when using Super Cruise. We were heading south on I-41 and super cruise is active and set around 80 mph, I entered an area where Super Cruise became unavailable or the system indicates that road information is not available, the vehicle immediately began to rapidly decelerate to under 60 mph within 5 seconds of the vehicle notifying me with red bar on steering wheel and one buzz of my seat. Causing serious concern for safety of my family in the vehicle. During this deceleration, I am unable to override or stop it - pressing the brake pedal does not cancel the slowdown, applying the accelerator has no effect, and no control buttons will disengage Super Cruise. All pedals are dead. All buttons to cancel do not disengage what the CAR is doing. …
"Phantom Braking" with over 13 events the 2024 CHEVROLET TRAVERSE LT unexpected and abrupt activated the Automatic Emergency Braking (AEB) system when there was no obstacle, vehicle, or collision risk present! If an Mac Truck was behind us tailgating at the time we would have been killed! The dealer is downplaying the issue acting like they have never seen this before. They question is we know what AEB is and how it works "WE DO!". On top of that the 2024 CHEVROLET TRAVERSE LT breaks are completely defective. Deal inspected them on 6/25/2025 then we purchased on 8/14 drove it for 2,290 miles and they claim the breaks needed replacement. So we paid for that and still the breaks make a bad grinding sound and it is hard to stop the SUV. Please investigate ;(
I was unable to stop my vehicle from accelerating. The brakes were engaging but my vehicle continued to build speed. Myself and my family, as well as others on the road, were all put at risk due to my vehicle not responding or failing to control speed; cruise control was not engaged. My insurance company, USAA, is currently investigating and determining total damage estimate. No warning lamps, indicators, or messages were presented prior to collision. The rotors and brakes were glowing red after collision from continuous attempts to stop the vehicle.
Occasionally when putting the SUV in reverse, the car does not go into gear. I'll hit the gas and nothing and then all of the sudden it goes into gear. It's almost like it's in a delay sometimes I'll have to put into drive and then reverse for it to go into gear.
I was on the interstate trying to merge into traffic and I floored the gas pedal to get into position with the flow of traffic. Upon pushing the gas pedal to its full position the pedal snapped off and I lost my ability to accelerate. I was lucky enough to be able to pull off to the side of the interstate and into the grass. I placed the Traverse into neutral and came to a stop. The gas pedal snapped just above the tab that sticks out where it connects to the module. Very unsafe that this is even a possibility to have happened. I would not recommend plastic for the gas pedal. Thank God the brake pedal is metal.
Cracked exhaust & bracket back in 2023 causing a loud rattling noise. Now catalytic converter is cracked & gasket leak. Dealer does have notes that it was cracked & they noticed it in 2023 at 46k miles & that converter has now cracked causing engine light to turn on. Car does not speed up properly & GM only wants to cover 30 percent of cost.
