Adaptive Cruise Control problems of the 2025 Chevrolet Equinox

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.

My vehicle randomly turns off the foward collision system causing its supercruise system and adaptive cruise control to turn off while driving on the highway potentially causing and accident. I took it to the dealer in marlton NJ with the foward collision fault light on and they cant find anything wrong with the system as it resets itself after thr vehicle is turned off for two minutes. On our facebook page I am not the only one who is experiencing this I will attach some documents of similar issues apparently gm has been aware of this for a while and no fix yet.

See NHTSA 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 NHTSA 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.

- the telematics module is bad, resulting in vehicle having no connectivity (gps, entertaintment system, updates) - the car has no other means of hands-free operation for navigation software (no carplay or similar phone projection technology) - gm is unable or unwilling to supply the parts for warranty repair. - it is illegal to use the phone while operating vehicle in my state (florida).

I was driving my 2025 Chevrolet Equinox ev on the highway with adaptive cruise control (acc) engaged. The vehicle was also set to "one-pedal driving" (high regenerative braking). The vehicle in front of me slowed down abruptly. My vehicle's acc began to slow the car, but it was not decelerating quickly enough to avoid a collision. I immediately intervened by pressing the brake pedal as hard as I could, pushing it completely to the floor. Critical safety failure: the vehicle's physical brakes failed to engage. Despite my foot being pressed hard to the floor, the vehicle did not slow down. It felt as though only the regenerative braking was (slowly) working and that my manual brake application had zero effect. The vehicle continued to glide forward with no significant braking power, and I was unable to stop the car in time, resulting in a collision with the rear of the vehicle ahead. Summary of defect: the primary safety failure was the complete lack of response from the manual brake pedal. My attempt to override the vehicle's automated systems in an emergency was unsuccessful, as the brake pedal was unresponsive. Reporting history: I have already reported this incident to my auto insurance, my local Chevrolet dealership, and the Chevrolet customer assistance center. A representative from Chevrolet recommended that I file this report with the NHTSA to help identify and track similar safety-critical incidents.

My vehicle seemed to accelerate when pulling into a parking spot at my work. It then launched over the curb sending me rolling down the hillside several feet. I required extraction and the car is now totaled. I am available to explain more and share pictures at your convince.

Car randomly brakes hard when traveling at highway speeds with adaptive cruise control active. Happens about once a day.

On star telematics is not working the issue is effecting gps and most importantly the adaptive driving system including cruise control system. I have stopped using these services to due an intermittent failure while driving. The adaptive cruise will disengage itself. Also the collision avoidance system will initiate braking randomly. I was told that the replacement parts are not available and or “extremely long wait time”. I’m not comfortable driving this vehicle and have no options but to continue until the lease is up.

Driving down rural highway (interstate 43 in northern walworth county, WI, divided access restricted freeway) the car panic braked with no car or obstacle in front of it. No warning sign, no error message, called onstar and they reported no faults, took to Chevrolet dealership and they reported no issue. Car also has had phantom alerts from the forward collision warning system.

Every car I’ve ever owned the cruise control disengages once you touch the brakes and does not reengage without pushing the button to say resume. On several occasions, this car has reengaged sometimes many minutes after I’ve touched the brakes multiple times such as in a parking lot or parking garage going around the corner the car resumes cruise, and rapidly accelerates, which is very dangerous in a parking lot or parking garage.
