NHTSA Complaint #11209997 — 2018 CHEVROLET MALIBU

PURCHASED 2018 CHEVY MALIBU WITH 4,200 BUT NEW DUE TO IT BEING A DEALER COURTESY CAR ON 12/18/18, ON 1/7/19 THE CAR WOULD NOT ACCELERATE WHILE STATIONARY IN A PARKING LOT ATTEMPTING TO PULL OUT OF THE PARKING SPOT. I PUT THE CAR IN PARK AND WHEN SHIFTING BACK TO DRIVE THE TRANSMISSION SLAMMED INTO GEAR AND THE ACCELERATOR BARELY RESPONDED AND THE CAR REVVED TO OVER 5,000 RPM'S. I TOOK INTO SUPERIOR CHEVROLET ON 1/8/19, ON 1/11/19 THEY STILL DID NOT KNOW WHAT THE ISSUE WAS AND WERE UNABLE TO DUPLICATE IT. ON 1/4/19 THE DEALERSHIP SAID THEY WERE CONNECTING THE CAR TO A MACHINE THAT WOULD SUPPLY THE SMALLEST SPECS OF THE CAR TO SEND TO GM ENGINEERS, ON 1/16/19 THE GM ENGINEERS ADVISED TO REPLACE THE TCM (TRANSMISSION CONTROL MODULE). TCM WAS REPLACED AND THE CAR WAS PICKED UP ON 1/18/19. ON 5/22/19 WHILE DRIVING THROUGH AN INTERSECTION THE ACCELERATOR FAILED TO RESPOND AGAIN AND REVVED TO 5,500 RPM'S. IT TOOK APPROX ONE MINUTE FOR THE ACCELERATOR TO RESPOND IN THE MEANTIME I WAS ALMOST REAR-ENDED BY THE CAR BEHIND ME. I TOOK THE CAR BACK TO SUPERIOR CHEVROLET ON 5/23/19 REPORTING THE ACCELERATOR DID NOT RESPOND AGAIN AS IT HAD IN JANUARY. THE TECHS WERE UNABLE TO DUPLICATE THE ISSUE AGAIN AND THE SERVICE MANAGER DROVE THE CAR HOME TO SEE IF IT WOULD DUPLICATE, IT DID NOT. ON 5/24/19 I WAS ADVISED THEY UPDATED THE COMPUTER AND THAT SHOULD RESOLVE THE PROBLEM THIS TIME. THE FIRST FAILURE HAPPENED AT APPROX 4,700 MILES. THE SECOND OCCURRING AT APPROX 11,700. THE CONSUMER STATED UPON THE 3RD FAILURE THE ONSTAR DIAGNOSTIC STATED THAT THERE WAS AN ISSUE WITH THE ENGINE AND TRANSMISSION SYSTEM. *JS
