Adaptive Cruise Control problems of the 2024 Chevrolet Equinox

Vehicle suddenly brakes aggressively for no reason ! blue sky no weather events no obstructions ! it also happens I reverse!!! at 60 mph I 4 lanes it’s not fun!!!!!!.

I was driving south on interstate 55 near arnold missouri in adaptive cruise control mode at approximately 65 mph when the car braked suddenly and came to a complete stop on the interstate. Car would not go forward after stopping. Turned the car off and restarted and the car now would drive normally. Have not used acc since and car has behaved normally. Took the car to dealership in farmington, mo and they reported no error codes and no recalls. I had driven over 13,000 miles in the car without any incidents previously.

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.
