  MY 2018 ACADIA KEEPS GIVING ERROR MESSAGE "SHIFT TO PARK" , IT HAS DRAINED MY BATTERY TWICE I HAD TO GET NEW ONE. IN ORDER TO SHUT OFF ERROR, I HAVE TO RESTART IGNITION AND MOVE SHIFTER TO DRIVE OR REVERSE SEVERAL TIMES BEFORE ERROR MESSAGE TO SHUT OFF. AT TIMES THE VEHICLE STILL THINKS IT IS ON AND THEN DRAINS BATTERY. I BROUGHT IT IN ON SEPTEMBER 2019 AND THE DEALERSHIP REPLACED THE HARNESS HOWEVER IT HAS STARTED AGAIN. MY WARRANTY IS ABOUT TO EXPIRE. IF THIS HAPPENS AGAIN I WILL NEED TO PAY OUT OF POCKET. I HAVE NOT RECEIVED ANY RECALL NOTIFICATIONS FROM GMC. THIS IS VERY FRUSTRATING AND IT IS A SAFETY HAZARD AS WE DON'T KNOW IF CAR IS ON PARK.

  Car has started displaying a "shift vehicle into park" message when I have put the car in park. Even though the care is clearly in park this warning displays and I'm unable to turn the vehicle completely off. Have re restart and mess with the shifter several times in order to be able to turn the vehicle off and lock the doors.

The vehicle was then taken back a fourth time where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 87,000.

  Had to replace the shifter, harness, and parking assist module to the tune of $1569.00! When it was put into park the system would not acknowledge it was in park...therefore I could not lock the vehicle and an alarm kept going off. My Acadia only has 12,000 miles on it...NO excuse for having to replace those parts with or without a warranty! Dealership said I am not the only one this has happened to...they have replaced a number of them!

  PUT CAR IN PARK AND PUSH BUTTON TO SHUT CAR OFF AND MOTOR TURNS OFF BUT IT'S IN ACCESSORY MODE AND THE DISPLAY MESSAGE SAYS TO SHIFT TO PARK. TAKES NUMEROUS TIMES TURNING CAR ON AND OFF AND MOVING THE SHIFT BUTTON AROUND BEFORE IT RECOGNIZES THAT THE CAR IS IN PARK. IT STARTED A MONTH AGE WHERE IT WOULD HAPPEN ONLY ONCE AND WHEN I TURNED THE CAR ON AND BACK OFF IT STAYED OFF WHICH MADE ME THINK IT WAS HUMAN ERROR. THIS LAST TIME IT TOOK ME AN HOUR BEFORE IT RECOGNIZED IT WAS IN PARK SEARCH THE INTERNET AND SEE OTHER PEOPLE HAVING THE SAME PROBLEM AND GMC IS AWARE BUT NO RECALLS.

  The warning light for a steering assist needs service came on the dash. The dealer had a code (po128) that pertained to a bad thermostat and coolant temp. sensor. The steering assist could have failed, along with possible engine damage. The dealer replaced the thermostat and the coolant temp sensor. Their were no police or insurance reports needed.

  ON DECEMBER 5TH 2019, I ARRIVED HOME FROM WORK TO TAKE MY SON TO HIS DR. APT. I PULLED INTO MY DRIVEWAY AROUND 10:30AM. I LEFT THE CAR ON SO MY SON WOULDN'T HAVE TO GO INTO A COLD CAR, BEING HE WAY SICK. I RAN INTO MY HOUSE WHERE MY MOTHER WAS WATCHING BOTH MY SONS. I SAID TO MY MOM, LET ME USE THE RESTROOM QUICKLY BEFORE I GET HIS COAT ON. I WAS NO MORE THAN 2 MINS. AS I STEPPED OUT THE BATHROOM, I HEAR MY HUSBAND SCREAMING FROM UP STAIRS THE CAR IS ON FIRE! HE COMES RUNNING DOWN THERE STAIRS AS FAST AS HE CAN, ALMOST INJURING HIMSELF BECAUSE HE DIDN'T SEE ME YET AND THOUGHT I WAS IN THE CAR! HE THEN SEES ME AND GRABS THE FIRE EXTINGUISHER. HE RUNS OUTSIDE TO TRY AND EXTINGUISH THE FIRE..AS I CALLED THE FRANKLIN SQUARE FIRE DEPARTMENT AND 911. BUT IN UNDER THE 5 MINS THE CAR WAS ENGULFED IN FLAMES! WE HAD TO THEN EVACUATE THE HOUSE BECAUSE THE GARAGE IS AN ATTACHED GARAGE AND THE CAR WAS IN THE DRIVEWAY OF THE GARAGE. MY POOR KIDS WERE FRIGHTENED FOR THEIR LIFE AS WE RUSHED THEM OUT THE HOUSE AS THEIR MOMMYS CAR WAS UP IN FLAMES..THEY WERE CRYING THEIR EYES OUT IN FEAR. THE FIRE CAUGHT ONTO THE TREE ON THE FRONT LAWN AS WELL AS DESTROYING THE GARAGE AND DRIVEWAY. I CRIED EXTENSIVELY THINKING OF THE WHAT IFS...WHAT IF I PUT MY SON AND I DIRECTLY INTO THE CAR, WITHOUT USING THE RESTROOM THAT DAY. WHAT IF THIS HAD OCCURRED WHEN I WAS DRIVING ON THE PARKWAY WITH MY WHOLE FAMILY IN THE VEHICLE. THIS VEHICLE WAS A DEATH TRAP THAT ALMOST TOOK MY LIFE AND MY FAMILY. WE FOUND THAT THEIR HAD BEEN A RECALL ON THE GMC ACADIA FOR THE 2017-2018 EDITIONS. I HAVING A 2018, WHERE WAS MY NOTIFICATION OF A RECALL? WHERE WAS MY LETTER..EMAIL..CALL FROM GM? I HAVE NUMEROUS FRIENDS THE RECOMMEND THE GMC ACADIA AS A GREAT FAMILY CAR. THEY ARE ALL NOW SCARED TO DEATH BECAUSE OF WHAT HAPPENED TO ME. NON FEEL SAFE USING THEIR VEHICLE NOW.

  The car is put in park but the it doesn’t detect that it’s in park and won’t turn off. You can’t get out of your car because the won’t turn off. There were no errors before this. I get an error message that says shift to park. I have to shift the car into drive and then park several times to make the car turn register that it’s in park The dealership has not looked at my car. Nothing has ever been wrong with my car. I have read online that it’s a problem for many people with Arcadia vehicles .

  WHEN I PUT THE IN PARK, IT DOES NOT RECOGNIZE THAT THE VEHICLE IS ALREADY ENGAGED. THE CONSOLE DISPLAYS TELLS ME TO PUT VEHICLE IN PARK AND BEEPS. I HAVE TO KEEP MOVING THE GEAR SHIFT FROM REVERSE TO NEUTRAL TO PARK SEVERAL TIMES BEFORE IT RECOGNIZES THE VEHICLE IN ENGAGED IN PARK. THIS HAS BEEN HAPPENING ABOUT 8 MONTHS OR SO. I HAVE MENTIONED IT TO THE DEALER AND THEY TELL ME THEIR ARE NO RECALLS FOR MY PROBLEM, NOT EVEN RECOGNIZING MY PROBLEM WITH THE VEHICLE.

  I have been having issues with shift to park message for a yr now and it just gets worse and do not have the funds to pay for it myself bu5 see that it is a recall and gm is covering cost for other makes models of my same yr for same issue takes sometimes 20 minutes to mess with my shifter until I can finally park my car where it shuts completely off. This is a safety risk as 1 it could roll away if it isn't 2 my car could drain and die leaving me stranded by not turning off fully one time. This is ridiculous I called gm and all they just pushed me off I don't understand how this is not being taken serious especially knowing this is a known problem!

  Shift to park message has appeared again and the engine will not cut off. First happened in Feb 2020, mileage was 31,143. Took to Dealer and new wiring harness was installed. Had to take back to dealer April 2020 for same problem; shifter assembly was replaced at that time. Shift to park message came back on August 2023. Took back to Dealer and shifter harness replaced again and jumper harness was installed. Mileage was 52,993. Shift to park message has once again appeared, December 2025. Having to put car in park and push engine on/off button numerous times before engine will finally shut off.....sometimes having to unhook battery in order to kill the engine. This will be the fourth time we have had the same recurring issue repaired. My husband read through over half the 352 registered complaints and at least three fourths of them were all about the SHIFT TO PARK problem! As a female, I don't feel safe driving my Acadia not knowing if the engine will cut off or if it's actually in park or if the car will roll. Why can't GM fix this issue!!!!!! They should definitely be held accountable instead of ignoring the complaints!

• 12/08/2019· ELECTRICAL SYSTEM

  I PUT THE CAR IN PARK, BUT THE INSTRUMENT PANEL READS "SHIFT TO PARK." THE ENGINE TURNS OFF, BUT THE ELECTRICAL SYSTEM STAYS ON BECAUSE THE CAR DOESN'T THINK IT'S ACTUALLY IN PARK. I HAVE TO TURN THE ENGINE BACK ON, SHIFT TO ANOTHER GEAR, SHIFT BACK TO PARK, AND TURN THE ENGINE OFF TO SEE IF IT REGISTERS THAT THE CAR IS IN PARK. I'VE HAD TO DO THIS SEVERAL TIMES BEFORE THE CAR ACTUALLY REGISTERS THAT ITS IN PARK AND WILL COMPLETELY TURN OFF.

  The contact owns a 2018 GMC Acadia. The contact stated that after shifting to the park(P), there was an audible warning alarm activated, and the message "Shift to Park" was displayed, and the vehicle failed to immediately turn off. After restarting the vehicle and jiggling the gear shifter, the failure was corrected. The vehicle was taken to the local dealer, who diagnosed the vehicle and determined that the gear shifter assembly was faulty and needed to be replaced. The vehicle was repaired, but while picking up her daughter from school, the gear shifter was shifted into park(P), and moments later, the vehicle started rolling backwards. The contact had to activate the parking brake to stop the vehicle. The vehicle was later towed back to the dealer. The cause of the failure was not yet determined. The manufacturer was not notified of the failures. The failure mileage was 120,000.

  MY 2018 GMC ACADIA SLT-1 HAS BEEN HAVING ACCELERATION ISSUES LIKE SHUDDERING AND OR FEELS LIKE A FULL LOSS OF POWER , WITH NO CHECK ENGINE LIGHT. I'VE TAKEN IT INTO THE DEALERSHIP TWICE FOR THIS PROBLEM . I'VE ONLY TAKEN IT IN THIS 2ND TIME BECAUSE IT GOT WORSE AND SCARED ME THAT IT WOULD DIE ON THE HIGHWAY. IT ALSO HAS HAD TO HAVE THE BATTERY CHARGED 3 TIMES IN A COUPLE OF WEEKS , YET THE DEALER SAYS THE BATTERY CHECKS GOOD. AT THE LEAST I BELIEVED SINCE ITS UNDER WARRANTY THEY WOULD CHANGE THE BATTERY IN THE CASE THE COMPUTER IS CAUSING ISSUES BASED ON BATTERY VOLTAGE. THE ALTERNATOR IS WORKING , BUT WITH ONLY 29K MILES NONE OF THIS BATTERY NOR ACCELERATION SHUDDER AND STUMBLE LIKE ITS GOING TO DIE SHOULD BE ACCEPTABLE.

  Shift to park notification keeps coming on after shutting off the car. It obviously has been shifted in to park before turning off the engine, but the notification keeps popping up. I have had the shift harness replaced by a mechanic once alreafy. He says this is the GMC authorized fix. IT DID NOT FIX THe PROBLEM! Of course, he'll put another shift harness for me, but what are the odds that will solve anything. GMC needs to come up with a better solution! It is frustrating and time consuming trying to come up with whichever trick will work to make the notification to away. I am not a very happy customer!

• 11/25/2021· ELECTRICAL SYSTEM

  My “Shift to Park” warning light pops up when attempting to park the car and shut off the engine. My wife had the problem at the grocery store and was very upset. This problem is constantly happening, my wife refuses to drive the car. I called the GMC dealer to get it looked at and was told it would be 2 weeks until they could diagnose the problem. Also it would cost $150 to look at it and I see the repair could be between $400 and $2000. The warning lights won’t stop and the constant bell dinging won’t stop until the battery is dead. All anyone has to do is Google “ shift to park” to see this is a defective switch. Many states have filed class action suits. A recall needs to be issued. My car has 33k miles on it.

  Shift to park issue is getting worse. I couldn’t turn my car off for hours today. The recall is still pending for this and GMC is doing nothing after thousands of class action lawsuits and complaints. Keeping my car running for hours on end while in park because it won’t turn off is causing electrical issues and using tons of gas. I have to get with an attorney at this point because I can’t use my car lots of the times because I can’t leave it running and unlocked all day while I’m at work or at the store. It’s a MASSIVE safety issue. GMC needs to take accountability and fix these vehicles. This has been ongoing for 2 years now.

  THE VEHICLE WILL NOT ALWAYS GO INTO PARK. IN ORDER TO GET IT INTO PARK YOU HAVE TO REPEATEDLY SHIFT OUT OF PARK AND BACK INTO PARK UNTIL IT WILL GO INTO PARK. IF IT IS NOT IN PARK THE VEHICLE WILL NOT LOCK AND WILL NOT POWER DOWN. SINCE IT WILL NOT GO INTO PARK IF THE VEHICLE WAS ON A HILL AND IT DID NOT GO INTO PARK THEN IT WOULD HAVE THE CHANCE TO ROLL DOWN THE HILL. I HAVE NOT ATTEMPTED TO SEE IF IT WILL ROLL DOWN THE HILL NOR AM I GOING TO TRY BUT SEEING HOW IT SHOWS ON THE INSTRUMENT CLUSTER THAT THE VEHICLE IS IN NEUTRAL I'M SURE IT WILL ROLL IF GIVEN THE CHANCE.
