2018 GMC Acadia

TL* THE CONTACT OWNS A 2018 GMC ACADIA. THE CONTACT STATED THAT AFTER STOPPING THE VEHICLE AND PLACING THE GEAR SHIFTER IN PARK, A MESSAGE DISPLAYED TO SHIFT THE VEHICLE INTO PARK. THE CONTACT SHIFTED THROUGH THE GEARS AND THE VEHICLE OPERATED AS INTENDED. THE VEHICLE WAS NOT TAKEN TO BE DIAGNOSED NOR REPAIRED. NEITHER THE MANUFACTURER NOR THE DEALER WERE NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 41,000. THE VIN WAS INVALID.

WHEN GEAR LEVER IS SHIFTED INTO PARK AND YOU TRY TO TURN OF THE ENGINE A NOTICE COMES ON TELLING YOU TO PUT YOUR CAR INTO PARK. I CAN NOT TURN OFF THE CAR UNTIL THIS MESSAGE DISAPPEARS. SOMETIMES IT TAKES 7 OR MORE TRIES TO FINALLY BE ABLE TO SHUT OFF THE CAR. IF I LEAVE IT WITH THE MESSAGE THEN ALL ELECTRICAL SEEMS TO STAY ON.

WHEN ATTEMPTING TO TURN THE VEHICLE OFF AFTER SHIFTING TO PARK AND THEN PRESSING THE START/STOP BUTTON, THE VEHICLE GIVES AN ERROR MESSAGE THAT SAYS "SHIFT TO PARK" EVEN THOUGH THE SHIFT LEVER IS IN THE PARK POSITION. THE ERROR MESSAGE PREVENTS THE VEHICLE FROM SHUTTING DOWN. THIS OCCURS WHEN THE VEHICLE IS STOPPED, PUT INTO PARK, AND THEN WHEN ATTEMPTING TO SHUT DOWN THE VEHICLE.

TL* THE CONTACT OWNS A 2018 GMC ACADIA. THE CONTACT STATED THAT WHEN THE GEAR WAS SHIFTED INTO PARK, A WARNING BEEP SOUNDED, INFORMED THE DRIVER THAT THE VEHICLE WAS NOT IN PARK. THE CONTACT WAS UNABLE TO TURN THE VEHICLE OFF. AFTER SEVERAL ATTEMPTS, THE CONTACT WAS ABLE TO SHIFT THE VEHICLE INTO PARK AND TURN THE VEHICLE OFF. THE MANUFACTURER WAS CONTACTED. THE VEHICLE WAS NOT TAKEN TO THE DEALER TO BE DIAGNOSED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 37,000. THE VIN WAS INVALID.

WENT CAR IS PARK THE DASH STILL SHOWS 'PUT CAR IN PARK' CAR WILL CONTINUE TO PEE, WILL NOT LOCK. FROM WHAT I READ GMC KNEW OF THIS PROBLEM BUT CONTINUE TO SELL GMC ARCADIA FROM 2017 TO 2018. EVEN THOUGH THIS IS A KNOWN PROBLEM THEY STILL CHARGE THE CONSUMERS FOR THE REPAIRS. THIS ONLY HAPPENED WENT TRYING TO PUT VEHICLE I PARK.

VEHICLE WILL NOT ACKNOWLEDGE THAT IT IS IN PARK. FORCES ELECTRICAL TO STAY ON, AND SOMETIMES WILL NOT ENGAGE PARK SO VEHICLE CAN MOVE AS IF I'M NEUTRAL. HAS THUS FAR HAPPENED WITH VEHICLE STOPPED, BUT YOU CAN SOMETIMES SHUT OFF ENGINE AND EXIT VEHICLE WHEN IT IS NOT IN PARK AND CAN ROLL AGAINST YOU, OR ON KIDS EXITING ETC. VEHICLE ROLLED IN GARAGE AND STRUCK, AND COULD HAVE CRUSHED CHILD AGAINST DOOR.

WHEN THE VEHICLE IS WARM, THE TRANSMISSION APPEARS TO SLIP WHEN SHIFTING FROM 2ND TO 3RD GEAR. THE ENGINE WILL REV BETWEEN 500 TO 1000 RPM WHILE SHIFTING. DURING THIS TIME (HALF TO FULL SECOND) THE VEHICLE IS NOT ACCELERATING AND DOES NOT RESPOND TO THROTTLE INPUTS. THE VEHICLE HAS BEEN TAKEN INTO DEALERSHIPS 4 TIMES FOR THIS COMPLAINT. AT 35000 MILES (3RD DEALER VISIT), GM REPLACED THE VALVE ASSEMBLY. THE PROBLEM REOCCURRED AND GM IS ONLY OFFERING TO REPLACE THE SAME PART, OR EXTEND THE WARRANTY ON THE TRANSMISSION, BUT NOT BOTH. NO ONE AT THE DEALERSHIP OR GM TECHNICAL ASSISTANCE CENTER HAS ANY IDEA WHAT IS ACTUALLY WRONG AND IS NOT TAKING ANY STEPS TO FIND THE CAUSE OF THE ISSUE. THE SERVICE MANAGER HAS ADMITTED THAT THERE IS A PROBLEM, BUT GM DENIED HIM ANY HELP IN RESOLVING THE ISSUE.THEY HAVE SAID THAT THIS IS NOT A SAFETY ISSUE, BUT I DO NOT FEEL COMFORTABLE DRIVING A CAR THAT MAY BECOME UNRESPONSIVE TO ACCELERATOR PEDAL INPUT FOR A FULL SECOND. NOTE THAT THIS ISSUE IS STILL COVERED BY THE POWERTRAIN WARRANTY AT THIS TIME.
