Adaptive Cruise Control problems of the 2020 Chevrolet Equinox

Adaptive cruise turn off and vehicle immediately decelerates. When traveling at highway speed with someone following closely behind you there is no warning that you’re decelerating. Also when this happens all cameras are off.

Adaptive cruise control, and automatic emergency braking intermittently fail to function.

Driving 75 miles per hour on interstate while passing two vehicles and one car behind me the car made a dinging noise, the adaptive cruise not available light illuminated and the car decelerated causing the car behind me to have to brake. If I had not stepped on the accelerator the car behind may have hit me. This has happened on four different dates and on one trip it happened 8 times in 80 miles. This is a safety hazard that could cause rear end collision at high speed. The repair shop at my chevy dealer in town says there are no error codes and the adaptive cruise is working as designed. Is I get hit from behind at high speed this could easily cause a devastating crash. I do not trust this car or the responses I am getting from the dealer. They say no one has complained about this but I kind find sites where people are reporting the same problem.

Complaint: owner states adaptive cruise control malfunctions without notice. Owner brought vehicle to local gm service department and vehicle was returned to customer as an unfounded complaint. Reporter found the following; all ipc indicators are functioning during self test, no ipc warning lights/messages present, distance following system appears to be functioning as designed and recognizes vehicles in its zone of influence. Reporter test drove vehicle with customers adas settings as dropped off. Adaptive cruise control did malfunction as customer indicated. Adaptive cruise control on engagement functioned as designed and then unexpectedly without warning failed. The most disturbing part of this fault is the only warning the system has failed is forward collision alarms. Secondly, the cruise control did not disengage upon this warning. If the prior were not enough, no ipc warnings or hard faults were recorded. This malfunction occurs unexpectedly at highway and local speeds. This fault, all the more worrisome, appears also to be either a programming error or transient. No other diagnostics were conducted. Supporting documents attached. Having personally owned adas equipped vehicles for over eight years and the confidence of using them without a problem this was a frightening experience for me and very concerning.
