2020 Chevrolet Equinox Collision Avoidance Problems

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.

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.
