Filed Jul 28, 2026 · Acceleration · 10,500 miles · FL

The contact owns a 2026 Chevrolet Equinox. The contact stated that while driving with the cruise control activated, the vehicle unintendedly accelerated from 50 MPH to 80 MPH. No warning light was illuminated. During the failure, three minor occupants were seated inside the vehicle. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 10,500.

While cruise control was active, the vehicle initiated un-commanded physical acceleration and deceleration in unpredictable 5 mph increments (up or down), forcing the vehicle to change speeds without driver input. This required me to immediately deactivate the system and override the accelerator/brakes to maintain control of the vehicle in while driving, creating a severe and direct safety hazard. With cruise off I could see the erratic jumping of the set-speed number on the digital display. This issue has occurred on two separate instances. In both cases, pulling over, turning the vehicle completely off, and turning back on completely cleared the glitch and restored normal operation of this feature.

Hello, since I purchased the vehicle on October 1, 2025, there have been issues regarding collison system and adaptive cruise control. When driving down the road it will try to come to a complete stop with no reasoning. It happens more often when it is rainy and night time. I believe the collision system is conufsed with oncoming traffic and it thinks they are on my side of the road but they are not. I also get alerts with side mirrors and shaking of my seat when no one is beside me. It triggers to say someone or a vehicle is approaching from the side, but there is no one or nothing there. The issue that is most troubling is I almost hit someone in the rear end on 02-03-2026. I went to slow down for a traffic light, and it started slowing down, but then got a surge and would not allow me to stop any more. It kept going. I had to remove my foot from the brake and hit it again harder. It has happened a few times, but not in a situation like this. Thankfully I was following a safe distance or I may have hit the vehicle stopped in front of me. Similar situation happened a few times, one when I was pulling into an Applebees to eat, the brake did not want to stop the vehicle. It was like a surge of power again. This time was not as bad as no one or a vehicle was not in front of me. I have also noticed it a few times driving and when I go to stop the surge, but it seems to be escalating. I do not have the auto start stop on, I switch it off as soon as I start the vehicle. I do not have the auto hold on when it happens either. I have an appointment on the 16th of February to hopefully get it looked at, but will see.

While driving South bound on an early morning drive in bright sun, the Forward Collision Avoidance/Alert System and Adaptive Cruise Control kept intermittently disabling itself. This continued to happen for 20 minutes.

When trying to disengage cruise control, with button on steering wheel, brakes locked up going 75mph on the interstate. Would not unlock until I physically pressed brake pedal. If I had not been able to control the car, we would have been sent head first into the concrete barrier wall. Also, when trying to start car or put in into gear, it tells me to "press brake" when the brake pedal is pressed as far as it can go. Radio will randomly cut off and screen goes blank. Trunk button on drivers door does not open trunk without pushing it minimum of 5 times. Sometimes it takes more.

My 2026 Chevrolet Equinox has been having problems; when cruise control is set it randomly puts itself into emergency park mode, the infotainment system loves to shut down which affects the entire vehicle. When this happens I can’t see my speed, every screen goes black and I have to pull over and reset the entire thing which takes a good 30 minutes, sometimes more. I have taken it to a shop which they said it was electrical and module issues, never told me exactly what or where and I’m having to struggle just to get the invoices. The problems are not currently resolved, it would’ve had to been in the shop for over a month and I can’t afford to be without a car that long with zero option of a rental. I have children. I got my car in May of this year with only 4 miles on it, been having the issues ever since.
