2019 GMC Acadia Power Train

Vehicle will not shift to park. Have to engage the parking brake to ensure vehicle will not roll away after shifting to park. Becuase the vehicle isn't actually shifting into park l, the vehicle will not shut off which drains the battery and leads to being unable to turnover the engine.

Shift knob stuck. Car will say shift to park after turning off car. Ended up draining battery. Needed to replace it after 34000 miles.

With the vehicle shifter in park and the dash indicating in is in park I get an error message stating to "Shift into Park." This has happened serval times in the last few weeks intermittently. I am very concerned this will strand my wife and child or lead to the vehicle unintentionally rolling away while unattended. While talking to several technicians at a GM test facility I have been told this was/is a common issue. While searching the NHTSA complaints multiple multiple complaints for this issue have bee submitted.

Gmc acadia keeps flashing the lamp that says to !shift to park, when the car is in park and will not turn off. Does not go off when I turn the car off and does not go off when I reshift the car to park. It takes several trys of putting it back in park then goes off, now it does this every time I park and turn the car off. I'm not the only one with this issue. Its been going on for over week now 38k-ish miles.

The Shift to Park warning message when shifter is already in park shows up on the dash information center. The gear assembly is not working properly, and the artificial intelligence does not recognize park when you are in park. You cannot turn the car off without repetitive turning car off and on and shifting back and forth between drive and park. I was going to live with this aggravation due to costly repair ($656.67), but I went online and found that the car may roll forward if it is not fixed in a timely manner and you don't know if it is in park causing danger if it rolls. Others say put the emergency brake on always. This is a safety issue. Jim Ellis said to bring it to your attention and also write a letter to GMC Corp. I also noted that there is a lawsuit against GMC as they have profited selling the Acadia with this defective gear assembly since 2012. This is the second generation 2017-2019 with the same safety issue problem. Also, you have to replace the battery due to the excessive usage it drains the battery ($219.12)

The contact owns a 2019 GMC Acadia. The contact stated that while parking the vehicle, the gear shifter was shifted into park(P) however, the "Shift to Park" message was displayed. The contact shifted the gear shifter back and forth and then shifted into park(P) before the proper gear was recognized. The failure caused the battery to drain. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 48,000.

When parking the suv and placing the gear shift in park, the notification system states “shift to park”. This has been happening daily for the last 3 weeks. Sometimes I can get the notification to go away when I push the button on the gear shift. Other times, I have to cut the car off and then back on for it to clear the notification.

'Shift to Park' appears on the dashboard after the vehicle is turned off and in Park. This issue can deplete the battery. The problem was confirmed by the dealer.

After vehicle is shifted into Park, "Shift into Park" message comes up. It requires you to restart vehicle, put in R, back into Park, sometimes jiggle the button, sometimes the entire shifter, sometimes drive around the block and start the process again. The message does not go away even if you exit the vehicle. 2017 Acadia had a recall for same issue, 2 years later still occurring but no recall. The repair is $600! GM offering nothing. Needs to be a recall, if you have an appointment it is sometimes 10-15 minutes of messing with the shifter ro driving around until you can shut your car off. I have been carrying tools and just disconnecting the battery if it won't shut off. Can't be 10-15 minutes late for work every day waiting for my car to agree it is actually in Park!

The contact owns a 2019 GMC Acadia. The contact stated while attempting to park the vehicle, the warning message to “Shift to Park” was illuminated. The contact was not able to shift the vehicle into park as needed. The contact turned off and restarted the vehicle however, the gear shifter failed to shift into park as needed. The contact manually turned the steering wheel from side to side while shifting the gear shifter until the vehicle responded and the vehicle was turned off. The vehicle was taken to the dealer to be diagnosed; however, the contact was unaware of the result. The contact was concerned that the failure was due to the transmission. The vehicle was not repaired. The manufacturer was contacted and stated that there was no recall for the failure. The contact was informed that the repair would not be covered. The failure mileage was 35,000.

Vehicle has had a hard shift since 15000 miles, always told at dealership it was normal. At 87493 my check engine light came on and code P2097-00- I was told it was that I had a bad battery and GM would not provide me one. Light was reset. Now at 98000 miles, shifting harder (automatic) like a jolt and vibrates going up hill- told I needed transmission fluid changed, this did nothing. This was confirmed by dealership prior to fluid change and then the dealership would not set up another appointment. Had this confirmed also by an independent service center. Occasionally a light will come on to say shift into park, despite being in park. No other messages related to this.

The vehicle intermittently fails to recognize that it has been put into park, flashing a message on the dash instructing the driver to “shift to park” even when the gear lever have already been moved to the ‘P’ position. I find it amazing that GMC even has a Service Bulletin No.: 19-NA-206 to address the situation (Intermittent Shift to Park Message Displayed While Vehicle in Park) but yet I had to pay $561.47 for the repair to ensure I don't injure my passengers and/or others.

Intermittent Shift to Park Message Displayed While Vehicle in Park, as detailed in NHTSA Bulletin 19-NA-206.

Occasionally my vehicle will say "Shift to Park" when I turn off the vehicle, but the vehicle is clearly in Park. It has been happening more frequently lately. I have researched this problem and it appears it has been a problem with several other GMC Acadia's as well.

The contact owns a 2019 GMC Acadia. The contact stated while driving at 45 MPH, the accelerator pedal was depressed however the vehicle failed to increase in speed and started to jerk. The “service stability track” warning message was displayed. The failure was intermittent. The contact took the vehicle to an auto store where there were no codes reported by the diagnostic tool. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 49,600.

WHEN I GOT TO WORK THIS MORNING, I PUT MY 2019 ACADIA IN PARK AND TRIED TO TURN OFF THE CAR. AN ALERT POPPED UP THAT SAID, "SHIFT TO PARK," BUT THE CAR WAS ALREADY IN PARK. I TURNED THE CAR OFF AND THEN BACK ON AND IT CORRECTED, BUT THIS IS THE SECOND TIME IN TWO DAYS THIS HAS HAPPENED.

WHEN I SHIFT THE CAR INTO PARK AND TURN THE CAR OFF, THE CAR INDICATES "SHIFT TO PARK" AND DINGS UNTIL I MOVE THE GEAR SHIFT AROUND FOR SEVERAL MINUTES, AND THEN THE INDICATOR STATEMENT AND SOUND STOP. THIS HAPPENS APPROXIMATELY HALF THE TIMES I PARK AND TURN THE CAR OFF.

PUT VEHICLE ON PARK AND MESSAGE APPEARED SAYING THAT IT'S NOT PARKED I GOT TO BACK UP AND PULL FORWARD A COUPLE TIMES UNTIL IT RECOGNIZES THAT VEHICLE IS ON PARK THEN I CAN TURN THE ENGINE OFF

MY 2019 ACADIA KEEPS BEEPING WHEN THE CAR IS IN PARK AND I SHIFT IT OFF WITH AN ERROR MESSAGE 'SHIFT TO PARK'. I HAVE TO TURN THE CAR BACK ON, SHIFT THE CAR OUT OF PARK AND BACK INTO PARK. I AM NOW DOING THIS 10 TIMES OR MORE. I CALLED THE DEALER AFTER RESEARCHING THAT THIS IS AN ISSUE WITH THE CAR AND HAVE NOT ISSUED A RECALL. THIS IS A PROBLEM. BY STARTING AND TURNING OFF MY 10 TIMES I AM PUTTING A STRAIN ON THE STARTER. I AM AFRAID THE CAR WILL ROLL WHEN IT'S OFF WITH THIS ERROR MESSAGE. *TR

THE MANUAL GEAR SHIFTER CONTROLS IN LOW GEAR ON THE CENTER CONSOLE DO NOT SHIFT. THE MANUAL CONTROL WORKED DURING THE TEST DRIVE AT THE DEALERSHIP WHEN THE CAR HAD 17 MILES ON IT, MARCH 10, 2019. THE SHIFTER FAILURE WAS FIRST NOTICED WHEN THE CAR HAD ABOUT 500 MILES ON IT, COMING DOWN A MOUNTAIN ON A HIGHWAY WHEN WE TRIED TO USE THE ENGINE TO BRAKE INSTEAD OF USING THE FOOT BRAKE ON MARCH 30, 2019. IN BETWEEN THOSE TWO DATES ON MARCH 21, 2019, THE CAR HAD A WATER LEAK AFTER IT RAINED THAT DRIPPED INTO THE CABIN OF THE CAR AND DIRECTLY ONTO THE SHIFTER AND OTHER ELECTRONIC CONTROLS. I BELIEVE THE GEAR SHIFTER FAILURE IS A DIRECT RESULT OF WATER DRIPPING ONTO THE SHIFTER AND OTHER ELECTRONICS ON THE CENTER CONSOLE. I HAVE 3 DOCUMENTED SERVICE RECORDS ATTEMPTING TO REPAIR THE WATER LEAK AFTER 3 SEPARATE RAINSTORMS THAT WAS ULTIMATELY DETERMINED BY GM ENGINEERING TO BE A MANUFACTURER DEFECT. WHEN THE GLASS IS POSITIONED FOR THE REAR MOONROOF, THE POSITIONER IS SUPPOSED TO HOLD THE GLASS IN PLACE FOR A MOMENT TO SEAL. INSTEAD THE POSITIONER MOVES CREATING AN AIR POCKET. THIS RESULTS IN WATER INTRUSION INTO THE CEILING OF THE VEHICLE AFTER RAIN, WHICH THEN SEEPS INTO THE FABRIC LINER AND DRIPS DIRECTLY ONTO THE CONTROLS. I AM WORRIED ABOUT WHERE ELSE WATER HAS TRAVELLED WITHIN THE CAR, KNOWING IT WAS MANUFACTURED IN JULY 2018 AND STORED OUTSIDE MOST OF ITS LIFE. THE SHIFTER IS THE FIRST OF WHAT I FORESEE AS MANY ELECTRICAL ISSUES THAT CAN ENSUE WITH WATER INTRUSION, AS IT HAS OCCURRED IN A CAR HAVING UNDER 900 MILES ON IT. WITH ALL ELECTRONIC TRANSMISSION CONTROLS, I AM WORRIED THAT IF WATER DAMAGED THE LOW GEAR SHIFTING, THERE COULD BE FUTURE AND MORE DETRIMENTAL TRANSMISSION MALFUNCTIONS (POSSIBLY CATASTROPHIC). BEYOND ELECTRICAL FAILURES, MOLD IS A WORRY IN THE HEADLINER AND CARPETS CREATING A HEALTH HAZARD IN MY VEHICLE WHERE I TRANSPORT MY TWO SMALL CHILDREN.

WHEN I TRY AND TURN THE CAR OFF IT HAS AN ERROR MESSAGE THAT SAYS "SHIFT TO PARK". IT APPEARS THAT THE CAR IS IN PARK BUT I AM UNABLE TO SHUT THE CAR OFF AND UNABLE TO LOCK THE DOORS.

WHEN I TRY AND TURN THE CAR OFF IT HAS AN ERROR MESSAGE THAT SAYS "SHIFT TO PARK". THE CAR IS ALREADY IN PARK AND MESSAGE STILL. NEED TO DO A IGNITION CYCLE TO REMOVE THE CONDITION AND BE ABLE TO TURN IT OFF. THIS CONDITION HAPPENED RANDOMLY, STILL OCCURRING ONE OR TWICE A WEEK.
