Open the full vehicle complaint log (all categories)CRUSE CONTROL DEACTIVATES AND WON'T REACTIVATE WHILE CRUISING AT HIGHWAY SPEEDS. SEEMS TO WORK AGAIN AFTER SHUTTING OFF AND RESTARTING. THIS HAS HAPPENED SEVERAL TIMES. LAST TIME IT HAPPENED THE ENGINE ALSO DIED. COASTED TO THE SIDE OF ROAD, WAITED A MINUTE AND CAR RESTARTED AND SEEMED FINE, BUT HAPPENED A SECOND TIME A FEW MINUTES LATER. I WAS ON A STATE HIGHWAY WITH LIGHT TRAFFIC SO WAS IN NO IMMEDIATE DANGER, BUT WOULD HATE FOR THIS TO HAPPEN ON A BUSY SIX LANE INTERSTATE. NO DIAGNOSTIC CODES WERE SET BY THE COMPUTER SYSTEM.

ON 10/10/2017 MY 2015 IMPALA 2LTZ HAD SUDDEN ACCELERATION, FULL THROTTLE. NO BRAKES, NO EMERGENCY BRAKE, THE ONLY WAY I COULD STOP THE CAR WAS TO PUT IT INTO NEUTRAL ( OVER 90 MPH BY THEN). THEN AGAIN ON 1/25/2018 THE SAME THING HAPPENED AGAIN, SUDDEN ACCELERATION, BY THEN I KNEW I HAD TO PUT IT IN NEUTRAL TO STOP. MY WIFE AND I WERE LUCKY I COULD MANEUVER THE CAR AROUND SEVERAL OTHER VEHICLES AND AVOIDED AN ACCIDENT. BOTH TIMES I WAS ON THE FREEWAY AT FREEWAY SPEEDS WITH THE ADAPTIVE CRUISE CONTROL ENGAGED.
I WAS DRIVING ON THE FREEWAY WITH THE ADAPTIVE CRUISE CONTROL ON AT ABOUT 50 TO 55 MPH WHEN SUDDENLY THE CAR WENT FULL ACCELERATION. I TRIED TO STOP THE CAR BY TURNING OFF THE CRUISE CONTROL, TURN OFF THE IGNITION, USE THE EMERGENCY BRAKE, NONE WORKED. I THEN PUT THE TRANSMISSION AND THEN EVERYTHING WORKED, BY THEN I WAS DOING 90 PLUS MILES PER HOUR PASSING VEHICLES. I CONTACTED GM AND THEY TRIED FIND A PROBLEM BUT DID NOT A PROBLEM.THEY SAID NO CODES APPEARED. THIS SUDDEN ACCELERATION LASTED ONLY A FEW SECONDS BEFORE I PUT THE CAR IN NEUTRAL. WILL A CODE APPEAR IF THE PROBLEM LASTED ONLY A FEW SECONDS. GM CLOSED THE CASE.
