2018 Chevrolet Traverse

I HAVE STARTED GETTING THE ERROR MESSAGE SHIFT TO PARK WHEN THE VEHICLE IS IN THE PARK MODE. IT IS NOT POSSIBLE TO SHUT OFF THE VEHICLE OFF WHILE THE ERROR IS PRESENT THE ISSUE OCCURS ON ALL SURFACES (FLAT AND SLOPED SURFACES ). THE ISSUE IS HAPPENING MORE FREQUENTLY AND AFTER RESEARCH APPEARS TO BE A WELL DOCUMENTED PROBLEM ON THIS VEHICLE.

TRANSMISSION - WILL NOT ENGAGE INTO DRIVE. WHEN YOU TRY TO ACCELERATE TRANSMISSION SHUTTER, JERKING, WILL NOT ENGAGE PROPERLY. YOU CAN FEEL IT NOW UNTIL SPEEDS OF 55 MPH. SITTING A STOP LIGHT. THE VEHICLE WILL ENGAGE SPEED ON ITS OWN. SOMETIMES IN THE MORNING START WILL NOT ENGAGE. STOP ENGINE GOES TO AUTO-STOP. ON DASH START ENGINE. MAJOR PROBLEMS. ALREADY HAD ECM REPROGRAMMED SEVERAL TIMES.

STARTED GETTING A "SHIFT TO PARK" MESSAGE WHEN TRYING TO SHUT OFF THE VEHICLE, EVEN TOUGH THE GEAR SHIFTER SHOWED BEING IN PARK. WHEN THIS OCCURRED, THE MOTOR WOULD TURN OFF, BUT THE ELECTRONICS IN THE CAR WOULD REMAIN ON. KEEP IN MIND THAT THIS VEHICLE USES A SMART KEY WITH PUSH BUTTON IGNITION AND DOOR LOCKS. IF THE BATTERY GOES DEAD, YOU HAVE TO BREAK INTO THE VEHICLE. A QUICK GOOGLE SEARCH SHOWED THIS TO BE A COMMON PROBLEM IN THE TRAVERSE. THE SHOP FOREMAN AT THE LOCAL DEALERSHIP CONFIRMED THIS TO BE A COMMON ISSUE. THE GEAR SHIFTER (ALSO ELECTRIC) HAD FAILED AND HAD TO BE REPLACED BY CHEVROLET.

2018 CHEVY TRAVERSE WHEN DECELERATING AROUND SPEEDS UNDER 35MPH CITY DRIVING THE VEHICLE WILL RANDOMLY REV UP AND THE RPM WILL GO UP TO 4000 OR 5000 RPM, THIS ALSO HAPPENS WHILE BRAKING. SOMETIMES THE CAR WILL JERK FORWARD AS IF IT WAS GOING TO ACCELERATE AND OTHER TIMES IT JUST STAYS AT A HIGH RPM FOR 5 SECONDS OR LESS UNTIL I EITHER COME TO A COMPLETE STOP OR TRY TO ACCELERATE AND IT DOES NOT RESPOND. THE ENGINE SOUNDS LIKE IT IS IN NEUTRAL AND THE ACCELERATOR IS BEING HELD DOWN. IT ALSO DOES NOT RESPOND TO THE GAS PEDAL WHEN IT IS REVING LIKE THIS, AND IF I TRY TO ACCELERATE THE CAR WILL EVENTUALLY KICK INTO GEAR AND LUNGE FORWARD. TOOK IT TO THE DEALER WITHING THE FIRST FEW MONTHS OF OWNING IT AND THEY COULD NOT REPLICATE THE ISSUE AND SAID THE COMPUTER DID NOT RETURN ANY ISSUE. THIS PROBLEM COMES AND GOES SINCE I BOUGHT THE CAR BRAND NEW IN 2018 AND CONCERNS ME, BECAUSE IT FEELS AS IF THE CAR IS ACCELERATING ON ITS OWN AND MAY CAUSE ME TO CRASH.

SEVERAL INSTANCES HAVE OCCURRED WHEN I HAVE PUT THE VEHICLE IN PARK AND ATTEMPTED TO TURN THE VEHICLE OFF I RECEIVED A MESSAGE "SHIFT TO PARK", EVEN THOUGH THE VEHICLE IS ALREADY IN PARK. WHEN THIS OCCURS, IT WILL NOT ALLOW ME TO TURN THE VEHICLE OFF. IT WILL TAKE SEVERAL MINUTES OF SHIFTING THE VEHICLE FROM DRIVE TO PARK BEFORE IT WILL REGISTER THE PARK POSITION.

THE VEHICLE AUTO-STOPPED AT A STOP SIGN. WHEN IT RESTARTED AND I MADE A RIGHT TURN OUT OF MY NEIGHBORHOOD, THE VEHICLE WOULD NOT ACCELERATE, IT WOULD ONLY LURCH. IT LURCHED AS IF SOMEONE WAS PUNCHING THE GAS PEDAL QUITE AGGRESSIVELY. THE VEHICLE'S ENGINE LIGHT EVENTUALLY ILLUMINATED. THE CAR HAD TO BE TOWED. AT THIS TIME THERE IS A SERVICE BULLETIN FOR THIS ISSUE (FROM FEBRUARY 2018) BUT NO KNOWN REPAIR.

THE CAR DOES NOT REGISTER WHEN THE CAR IS IN PARK AFTER I TURN IT OFF. IT READS 'SHIFT TO PARK' AND I HAVE TO SPEND SEVERAL MINUTES JIGGLING THE SHIFTER OR RESTARTING THE CAR AND GOING THROUGH DIFFERENT GEARS. IT IS A VERY BIG INCONVENIENCE. I TOOK IT TO THE REPAIR SHOP AS IT STARTED RIGHT AFTER THE WARRANTY RAN OUT. THEY SAID EITHER THE SHIFTER NEEDS TO BE REPLACED OR THE GEARBOX VIA A CONVERSATION THEY HAD WITH SOMEONE THEY HAD AT CHEVY. THEY WERE TOLD CHEVY AND GMC ARE AWARE OF IT BEING A PROBLEM BUT IT'S NOT ON A RECALL LEVEL YET.

TL* THE CONTACT OWNS A 2018 CHEVROLET TRAVERSE. WHILE ATTEMPTING TO PARK THE VEHICLE, THE GEAR SHIFTER FAILED TO SHIFT INTO GEAR AND THE "SHIFT TO PARK" MESSAGE WAS DISPLAYED. THE VEHICLE WAS TAKEN TO CAMINO REAL CHEVROLET (2401 S ATLANTIC BLVD, MONTEREY PARK, CA 91754, (323) 264-3050) WHERE IT WAS DIAGNOSED THAT THE GEAR SHIFTER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 9. THE VIN WAS UNKNOWN.
