2018 CHEVROLET VOLT Power Train Problems

When car is in park the vehicle sometimes does not recognize that and will not let you turn the car off. The display tells you that you need to shift to park but it is already in park. The problem is happening frequently now.

When shutting down the Chevy Bolt EV, the car is shifted into park, and with foot on the brake, the power button is pushed to shut down the power...but wit some regularity the car won't shut down and gives a "Shift To Park" message, even though it is in park. This is a safety hazard, because at times the car simply can't be turned off, meaning the driver can't exit the car and leave it behind. The problem is intermittent. I've experienced it MANY times. The problem is also apparently common, as there are hundreds of complaints about this problem on the internet (Search VOLT Shift to Park). Please ask GM to fix this problem.

When you put the car in Park, the engine would NOT shut off and the car kept sending a message that I needed to shift to park, but I already was in park. I shifted in and out of park to drive to reverse, but every time it went back to park it said I needed to shift to park. I was in my garage, could NOT leave the car running all night as the battery would be dead by morning, but couldn't shut it off either. I drove it immediately to the dealership and they reproduced and confirmed the problem, repaired it on Tuesday. Fortunately, I was at home, but had I been anywhere my safety and others could have been at risk, because I could have been in an unsafe place late at night, unable to shut my car off and/or get out of my own car.

The contact owns a 2018 Chevrolet Volt. The contact stated that while the gear shifter was in PARK, the shift to park warning light illuminated and the vehicle failed to turn off or change gears. The vehicle was taken to the dealer where it was diagnosed that the gear shifter assembly mechanism failed and needed to be replaced. The vehicle was repaired however, the failure recurred. The manufacturer was not notified of the failure. The failure mileage was approximate 28,995.

I have the shift to park error come on sporadically when the car is in park. Clicking the shift trigger a few times usually fixes it. Car won't fully turn off when the message is displayed.

PARK TO SHIFT ISSUE. WHEN CAR IS PLACED IN PARK IT IS NOT RECOGNIZED AND SAYS THAT ACTION IS REQUIRED. GIGGLING THE SHIFTER OR PRESSING THE BUTTON ON THE SHIFTER USUALLY TAKES CARE OF THE PROBLEM. THE CAR WILL NOT TURN OFF UNLESS IT RECOGNIZES IT IS IN PARK.

WHEN FULLY STOPPED AND IN PARK, TURNING CAR OFF, MESSAGE APPEARS 'SHIFT TO PARK' CAR IS ALREADY IN PARK. UPON PUSHING START TO TURN CAR OFF, MOST LIGHTS ETC. TURN OFF EXCEPT THE SPEEDO DISPLAY. NO WAY TO TURN IT OFF. CAR HORN HONKS UPON EXITING CAR WITH KEYS. SPEEDO LIGHTS STAY ON, DRAINING BATTERY BATTERY AND POSSIBLY TEMPTING A CAR THIEF.

WILL NOT SHUT OFF WHEN TRANSMISSION SHIFTED TO PARK.

VEHICLE WILL NOT TURN OFF ON A REGULAR BASIS.. RECEIVE A MESSAGE THAT READS: 'ACTION REQUIRED. SHIFT TO PARK.' WHEN THIS OCCURS, THE VEHICLE CAN NOT BE TURNED OFF OR LOCKED. RESEARCHED THIS PROBLEM ON THE INTERNET AND DISCOVERED THAT IT IS A VERY COMMON PROBLEM THAT AFFECTS NEARLY ALL 2016, 2017 AND 2018 CHEVROLET VOLTS. A RECALL SHOULD BE IMPLEMENTED!

VEHICLE WILL NOT SHUT DOWN PROPERLY. WHEN TRYING TO TURN OFF PUSH BUTTON IGNITION THE VEHICLE SAYS " ACTION REQUIRED: SHIFT TO PARK". THE VEHICLE IS ALREADY STOPPED AND IN PARK HOWEVER IT IS NOT REGISTERING SOMEHOW.

WHILE ATTEMPTING TO TURN THE CAR OFF- A MESSAGE APPEARS SAYING "ACTION REQUIRED- SHIFT INTO PARK". THE CAR IS IN PARK AND THE DASH REGISTERS THAT IT IS IN PARK, THE GEAR SHIFT IS LOCKED IN PARK BUT THE SYSTEM DOESN'T SENSE THAT IT IS IN PARK AND WON'T LET THE CAR SHUT OFF. HAS PROGRESSIVELY GOTTEN WORSE AND MORE FREQUENT.

VEHICLE GIVES A "SHIFT TO PARK" MESSAGE WHEN IT IS ALREADY IN PARK AND I AM ATTEMPTING TO TURN IT OFF. I HAVE TO SHIFT THE CAR BACK INTO DRIVE OR REVERSE AND THEN SHIFT IT BACK TO PARK MANY TIMES BEFORE IT ALLOWS ME TO TURN OFF THE VEHICLE. I TOOK IT TO BE REPAIRED TO MY LOCAL DEALERSHIP AND THEY REPLACED THE "SHIFTER IN-LINE WIRE HARNESS JUMPER", AS INDICATED ON MY INVOICE. TWO DAYS LATER, I AM HAVING THE SAME PROBLEMS AGAIN.

"SHIFT TO PARK" DISPLAYS ON THE SCREEN EVEN THOUGH THE CAR IS ALREADY IN PARK. ELECTRIC MOTOR WILL NOT SHUT OFF. AND NOW THE SHIFTER DOESN'T WORK AT ALL. WHEN PUT INTO DRIVE OR REVERSE THERE IS NO POWER TO THE WHEELS. THE VEHICLE IS STATIONARY WHEN THIS HAPPENS BECAUSE I WAS PARKING THE CAR. *TR

"SHIFT TO PARK" ERROR DISPLAYS AFTER SHIFTING THE CAR INTO PARK. WHEN THIS ERROR MESSAGE OCCURS, I AM UNABLE TO TURN OFF THE VEHICLE. *TR

WHEN I TRY TO TURN THE CAR OFF, IT SAYS I MUST SHIFT TO PARK, EVEN THOUGH THE CAR IS ALREADY IN PARK. AS A RESULT, I CAN'T TURN THE CAR OFF AND I CAN'T LEAVE IT BECAUSE THERE IS NO WAY TO LOCK THE DOORS WHEN IN THIS STATE. *TR

WHEN ATTEMPTING TO TURN OFF CAR AFTER DRIVING AND AFTER SHIFTING THE CAR INTO PARK, A MESSAGE APPEARS ON THE SCREEN TO SHIFT THE CAR TO PARK. EVEN THOUGH THE CAR IS ALREADY IN PARK THE MESSAGE REMAINS, AND THE CAR WON'T TURN OFF, OR WILL ONLY TURN OFF AFTER REPEATED ATTEMPTS AT SHIFTING THE CAR OUT OF AND BACK INTO PARK.

CAR SENDS NOTIFICATION TO "SHIFT TO PARK" WHEN SHIFTER IS IN THE PARK POSITION AND GEAR SELECTION INDICATOR DISPLAY INDICATES "P". CAR WILL NOT SHUT DOWN UNTIL SHIFT TO PARK CONDITION HAS BEEN SATISFIED BY FINESSING THE SHIFTER. THIS IS AN ISSUE OF SAFETY BECAUSE THE CAR CANNOT BE TURNED OFF.

WHEN I SHUT DOWN POWER IN PARK ON MY 2018 CHEVY VOLT (THE CAR IS STATIONARY) THE CAR WILL NOT COMPLETELY SHUT DOWN AND THE DASHBOARD DISPLAYS "SHIFT TO PARK". ESSENTIALLY, THE CAR IS NOT RECOGNIZING THAT THE CAR IS ALREADY IN PARK. I CAN NOT WALK AWAY FRO MY CAR BECAUSE IT REMAINS ON. IT TAKES MULTIPLE ATTEMPTS UNTIL IT ULTIMATELY WILL SHUT OFF. THIS HAS BEEN A COMMON ISSUE AS REPORTED BY OTHER CHEVY OWNERS.

WHEN ATTEMPTING TO POWER OFF VEHICLE AFTER SHIFTING TO PARK, AN ERROR MESSAGE IS DISPLAYED ON CONSOLE, "SHIFT TO PARK", AND THE VEHICLE WILL NOT POWER OFF. VEHICLE IS IN PARK WHEN THE ISSUE OCCURS, BUT REQUIRES SHIFTING OUT OF PARK, POSSIBLY MULTIPLE TIMES, TO ALLOW VEHICLE TO POWER OFF. ISSUE OCCURS DURING EACH USE OF VEHICLE.

SHIFT TO PARK ISSUE. WHEN THE CAR IS IN PARK THE CAR STILL REPORTS SHIFT TO PARK WHEN YOU TRY TO TURN IT OFF.

TL* THE CONTACT OWNS A 2018 CHEVROLET VOLT. WHILE DRIVING 55 MPH, THE VEHICLE JERKED FORWARD VIOLENTLY, SLOWED DOWN TO 45 MPH, AND THEN STALLED. ALSO, THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. THE CONTACT IMMEDIATELY POWERED OFF THE ENGINE IN THE MIDDLE OF TRAFFIC. THE VEHICLE WAS PUSHED OVER TO THE SIDE OF THE ROAD BY THE POLICE AND TOWED TO MAHER CHEVROLET (LOCATED AT 2901 34TH ST N, ST PETERSBURG, FL 33713). THE DEALER FOUND SEVERAL FAILURE CODES AND THE TRANSMISSION FLUID PUMP OUTLET SEAL, INTERNAL FILTER, AND SPACER PLATE WERE ALL REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND PROVIDED CASE NUMBER: 9-5251855943. THE APPROXIMATE FAILURE MILEAGE WAS 12,125.

WHILE DRIVING THE VEHICLE AT AROUND 60 MPH, THE 'CHECK ENGINE' LIGHT CAME ON AND A MESSAGE SAYING 'SHIFT TO PARK' APPEARS ON THE DASHBOARD. ONCE THE VEHICLE WAS STOPPED AT THE TRAFFIC LIGHT, THE DRIVER SHIFTED TO PARK AND WAS NOT ABLE TO PULL DOWN TO DRIVE AGAIN. VEHICLE WAS STRANDED IN THE MIDDLE OF THE ROAD WHILE CARS WERE APPROACHING FROM BEHIND WITH HIGH SPEED. AFTER REPEATED ATTEMPTS TO PRESS THE VEHICLE 'START' BUTTON, WE FINALLY WERE ABLE TO PULL DOWN TO NEUTRAL AND PUSHED THE VEHICLE TO THE SIDE OF THE ROAD. VEHICLE NEEDED TO BE TOWED TO DEALERSHIP FOR DIAGNOSIS.

I WAS DRIVING MY CAR ON FREEWAY AT 65 MPH AND SUDDENLY CAR DISPLAYED WARNING ON DASH BOARD TO SHIFT THE CAR IN PARK POSITION. CAR IMMEDIATELY LOST POWER FROM ENGINE. I HAD TO IMMEDIATELY PULL OVER CAR FROM LEFT MOST LANE TO BUFFER LANE BETWEEN FREEWAY AND EXIT. MY MOVE UNTIL IT HAD MOMENTUM. BUT THEM IT STOPPED ON FREEWAY. AFTER STOPPING CAR, IT DID NOT START OR STOP ENGINE. IT DISPLAYED CHECK ENGINE LIGHT. WHILE RESTARTING CAR, IT KEEP DISPLAYING "INITIALIZING" AND IMMEDIATELY SYSTEM REBOOT BY ITSELF. CAR DID NOT START AT ALL AND EVENTUALLY CAR HAD TO BE TOWED TO DEALERSHIP. CHEVROLET DEALER COULD NOT IDENTIFY ROOT CAUSE AND REPORTED THE ISSUE IS FIXED. AFTER FIVE DAYS, EXACTLY SAME ERROR OCCURRED AGAIN ON THE FREEWAY. AT THIS TIME, WITH HELP FROM ONSTAR, MULTIPLE ERROR CODE WERE RETRIEVED AND THEY WERE RELATED TO FAILURE IN HYBRID POWER TRAIN...
