2018 Chevrolet Traverse

Electrical ground problem affecting transmission control is evident by a Shift to Park warning that displays on the driver information center and prevents vehicle from being turned off. GM has this problem so we’ll documented that a TSB exists and is on file with NHTSA. The inability to turn off the vehicle when this is encountered is a significant safety issue. We paid out of pocket to have the fix recommended in the TSB applied to our vehicle.

When driving on a right hand curve with traffic in the opposite direction lane, the forward collision warning system flashed a large red warning flash on the instrument panel near the speedometer. This was alarming and caused me to put on the brakes immediately, although there was no impending crash. This cause the cars behind me to take evasive action and apply their brakes in an emergency fashion and almost cause several collisions.

The car does not recognize when the vehicle is in park. It will ding an error at you so you are unable to leave your vehicle. This error will continue to go off until you can find a trick to shut the car down. I work downtown and need to park in a garage. I was left sitting with an alarm going off for several days while I searched for tricks on my phone to get the error to turn off. I am a single female and I was put at risk because my car would not turn off. I had to sit in the garage alone until I could find a way to be able to leave my car.

When my vehicle has been shifted into park (the transmission shifter shifted into P for Park) and the engine has been turned off a "shift into Park" warning message is displayed on the dashboard and a warning chime sounds. My vehicle's ignition remains ON and the audio system does not shut off. The transmission shifter shows the P (Park selection) P as red indicating the transmission is in park and the transmission shifter is locked in the park position. I must restart my vehicle and re-shift the transmission selector back into park multiple times before my vehicle turns the vehicle's ignition to OFF.

WHEN SHIFTING INTO PARK AND ATTEMPTING TO TURN OFF THE CAR, 80% OF THE TIME THE VEHICLE WOULD NOT REGISTER THAT THE CAR WAS IN PARK AND ALLOW THE VEHICLE TO TURN OFF. IT WOULD ALARM & CHARM WITH A MESSAGE TO "SHIFT TO PARK". THIS IS A KNOWN MANUFACTURING ISSUES WITH THE CHEVROLET TRAVERSE, GMC ACADIAS, AND POSSIBLY OTHER MODELS OF CHEVY/GMC. THIS IS A MAJOR SAFETY CONCERN AS THERE IS NO WAY TO KNOW IF THE VEHICLE IS TRULY IN PARK AND CAN LEAVE YOU IN SCARY SITUATIONS WHEN YOU CANNOT TURN OFF THE CAR. WE HAVE ALSO BEEN STRANDED WITH A DEAD BATTERY BECAUSE THE "SHIFT TO PARK" CHIME AND MESSAGE DRAINED THE BATTERY. CHEVROLET HAS PROVIDED THEIR DEALERSHIPS WITH BULLETINS IN HOW TO ADD A JUMPER HARNESS AND ADD/REPLACE A SWITCH IN THE GEAR SHIFT ASSEMBLY TO CORRECT THE ISSUE, BUT REFUSE TO TAKE ACCOUNTABILITY. I HAVE HAD MULTIPLE SERVICE ADVISORS ADMIT THEY HAVE HAD TO FIX NUMEROUS GEAR SHIFTERS AND THAT THIS IS A KNOWN ISSUE. A RECALL NEEDS TO BE ISSUED ON THIS PROBLEM AS IT IS A SAFETY CONCERN FOR ANYONE AFFECTED. PLEASE ADDRESS! I AM INCLUDING MY RECEIPT ON THE SERVICE I HAD TO PAY FOR TO FIX THIS PROBLEM. ALSO AN EXAMPLE OF ONE OF THE TECHNICAL BULLETINS CHEVROLET HAS SENT THEIR SERVICE DEPARTMENT.

SHORTLY AFTER PURCHASE, MY CAR WOULD NOT ACKNOWLEDGE BEING PUT IN PARK. I WOULD SHIFT THE CONTROL TO PARK BUT WOULD GET WARNINGS PARK WAS NOT ENGAGED. I TOOK IT IN FOR REPAIR. NOW I AM GETTING A MESSAGE TO SERVICE PARKING BRAKE. THIS SEEMS TO BE A PROBLEM WITH THIS VEHICLE. I DO NOT USE THE PARKING BRAKE, SO I CAN'T UNDERSTAND WHY SERVICE IS NEEDED. BOTH PROBLEMS WERE WHEN CAR WAS IN PARK. THE 'SERVICE PARKING BRAKE' WARNING STAYS ON WHILE DRIVING.
