2023 Chevrolet Bolt Euv: adaptive cruise control problems

Filed May 25, 2025 · Acceleration, Driver assistance · MI

I was driving on a highway at approximately 68 MPH. There were no cars in front of me and none beside. The adaptive cruise control system was engaged. The car applied the brakes without warning, as if I was a going to collide with another vehicle. I depressed the brake to turn off the system and hit the gas pedal.

The adaptive cruise control as well as regular cruise control limits the electronic braking to 10 kW. After that the friction brakes take over. There is little indication of it, and I think it's a safety risk because in hilly areas, as well as mountainous roads, the friction brakes activate risking overheating the brakes and a brake failure. I believe the earlier model years would not limit the electronic braking and would maintain the speed down hills using regenerative braking exclusively.

The situation occurs when using supercruise (GM’s lane centering and adaptive cruise control system). Under certain conditions with super cruise engaged and one pedal drive mode active, pressing the cancel cruise button (example: taking manual control briefly in order to allow a merging car into your lane) causes the vehicle to abruptly decelerate without the ability to override with the pedal. This uncontrollable abrupt deceleration poses a hazard to vehicles behind me. This deceleration can only really be overridden by proactively pressing on the accelerator prior to disengaging the super cruise system. I suspect this problem is caused by logic in the super cruise system which does not allow the vehicle to accelerate while the steering wheel is flashing red (such as during disengagement). Generally, removing the flashing red condition from the steering wheel requires applying torque to the steering wheel. However, this is not practical when driving straight and needing to disengage the system. The supercruise system needs to be able to safely and properly disengage at the press of a button without needing to step on the accelerator. I believe that disengaging supercruise without pressure on the accelerator pedal should lead to the car defaulting to going into maximum one pedal braking yet still being able to accelerate on command if needed. The current state of the system requires torque on the steering wheel in order to be able to accelerate out of such a situation.

While using adaptive cruise control, the vehicle braked suddenly with no other cars or obstacles in view. If a vehicle was behind us, we would have been hit at 70 mph.

Adaptive cruise failed just over 2k miles following another vehicle under 60mph and sped up to set cruise of 75 and would have hit the truck if I didn’t stop it, I took video of failure directly after the incident. First bolt EUV camera failed more than once even after it was replaced, that car was bought back under battery recall. My point is, it’s a continued issue. With lane keep assist you must always be prepared for it not to function, it doesn’t always work and have to cycle the on/off button (same with previous EUV too). While in super cruise in my current vehicle it tried to locate the left lane but a big rig was on the line and my car appeared it was going to hit the truck multiple times within a few seconds as each time I had to bring the car back to the center until I turned it off. I have parts on order but I personally don’t believe that will be the end of based upon my two vehicles.

I was driving on CT Route 2 using super cruise. We came upon a construction zone and the bar on the steering wheel changed from green to red. The car came to a complete stop in the middle of the highway and didn't respond to the accelerator pedal. This is a frightening situation on a super highway. I tried pressing the buttons that turn on and off the cruise control, super cruise, etc. with no effect. Cars behind me passed on the left and right. I finally tried putting the car in Park and back into Drive. From that point on it worked normally. This is the second time this happened. The first time I had only had the car for a week, so I thought it was just a mistake on my part. I did have a dash cam running, but the files are too large. I will keep them on my computer should you wish to have them. The consumer stated that during this incident, they could not take over control from the Super Cruise.

On the freeway going 70 mph our car decided to slam on the brakes. We had it on supercruise which also uses adaptive cruise control. It was not raining, it was overcast, we were in farm country with no bridges or signs over the roadway. No cars around. It was very scary! I have 2 other cars with adaptive cruise control and have never experienced this.
