The contact owns a 2025 Chevrolet Equinox. The contact stated that while driving approximately 15 MPH or below and coming to a stop, the brake pedal was depressed, but the vehicle failed to respond as intended, and the brake pedal was pumped several times until the vehicle responded. The contact stated that the failure mostly occurred while driving on wet, gravel, and snowy roadways. The contact stated that on one occasion the vehicle drove through an intersection. The vehicle was taken to a dealer twice; however, the failure was not reproduced on the first visit. During the second visit, the contact was informed that the failure might be related to a cruise control recall, and a software update was completed; however, the failure persisted. The failure mileage was approximately 2,000.

The vehicle’s software, steering, and Advanced Driver Assistance Systems (ADAS) create severe, active driving hazards. First, the steering and traction programming cause violent, unprompted lane deviations. While driving 20 mph on a snowy dirt road, the system automatically engaged and violently pulled the vehicle directly into the lane of an oncoming snowplow. A similar erratic swerving event occurred at 25 mph on [XXX] during icy conditions. Most recently, the steering violently pulled the vehicle 6 feet to the left at 50 mph, despite the suspension and wheels being in perfect factory specification with summer tires mounted. As a professional heavy-vehicle driver, I had to manually fight the wheel to maintain the lane. Second, the Adaptive Cruise Control unpredictably fails to recognize stopped traffic on both interstates and town roads. It repeatedly fails to apply the brakes when a lead vehicle stops, requiring emergency manual braking to avoid rear-end collisions. The system also triggers severe phantom braking without warning. We are forced to manually disable traction control and parking assist upon every vehicle start just to avoid losing control of the vehicle. The dealership has evaluated the vehicle multiple times but has failed to resolve these core software and ADAS defects, despite months of ongoing negotiations with GM Corporate.

My telematics module for onstar is draining power from the car's battery which has been not allowing me to start after I turn it off without having to jumpstart it. Also when I do jump start it, the cruise control don't work and service messages pop up on my HUD. The dealership said it's undrivable due to safety concerns and the part is backordered for an unknown ETA.

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.

I was heading home from my vacation with my lady and had cruise control on and then all of a sudden my Rpms shot through the roof and then a flashing check engine light showed up and a message that said “acceleration reduced drive with care” when I took it to the dealer they told me it was due to the side object detection system malfunctioned and caused that issue then today I felt the car idle weird so I hooked up a scanner and it’s got a misfire on cylinder 2 and 4

The onstar telematics module has stopped functioning. That means I am not receiving any systems updates, cannot use onstar, and cannot use the my Chevrolet app for remote start or remote unlock. I took it to the dealer 2 weeks ago and they said the telematics module is backordered. They did do a number of system updates. After those updates my adaptive cruise control has completely stopped working. When I called about that, the service department said that one module could have caused the other module to fail and that they won’t try to look at my cruise control until after they can replace the telematics. There is currently no ETA to receive the part.

SEE the federal safety agency Safety Recall Report 25V-12- It appears it should apply to both 2025 FRONT WHEEL DRIVE Chevy Equinox EVs with ADAPTIVE CRUISE CONTROL (and without Super Cruise) in addition to 2025 ALL WHEEL DRIVE Equinox EVs with ACC (also without Super Cruise). This is very dangerous. Here's what happened: My 8 month old 2025 Chevrolet Equinox EV FRONT WHEEL DRIVE w/ACC(no Super Cruise) has had 2 instances where a very large "thunk" sound and vibration emanating from the rear of the car while stopped at an intersection, was immediately followed with sudden brake failure and sudden forward acceleration. The ACC was on in both instances. The first time this happened was alarming but since the was nothing in front of me there was no damage and the problem seemed to resolve itself thereafter. The second time was while waiting at a red light about 10 feet behind another vehicle. My car shot forward and into the other car, which was then pushed into the car ahead of it. Both my car and the car ahead of me had very expensive damages, but fortunately, no injuries. What I experienced sounds exactly like the recall problem described in the federal safety agency Safety Recall Report 25V-12 which has thus far only been applied to the AWD version of the 2025 Equinox EV, not the FWD version that I have. I believe this needs rapid consideration due to the danger of of sudden acceleration resulting in serious property damage, injury, or death. It appears to me that other instances of this problem have been described in various online forums and YouTubes.
