2018 GMC ACADIA Electrical System Problems

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!

SHIFTER PROBLEM 2018 GMC ACADIA. I NEVER RECEIVED A RECALL NOTICE OR BULLETIN ABOUT SHIFT TO PARK SHIFTER PROBLEM

SHIFT TO PARK WARNING IS COMING ON WHEN CAR IS CLEARLY IN PARK. HAVE TO JIGGLE GEAR SHIFT TO GET IT TO GO OFF. IT IS JUST RANDOM. SOMETIMES STAYS ON. I AM READING THIS IS A BIG PROBLEM WITH THIS MODEL CAR. CALLED DEALER AND THEY SAID THEY WOULD HAVE TO REPLACE GEAR SHIFT.

My Acadia has the shift to park default it has been fixed 3 times and now it is popping up again for the 4th time which means I can't turn my vehicle off it takes forever to get it to go off please help please help

Shifting to park and vehicle stating the vehicle is not in park, won't let me turn the vehicle off. Transmission going out, brought to many shops letting me know that the transmission is not working properly but won't give an engine light if anything is wrong with vehicle, Wont show on readers what is wrong with vehicle. Electrical, Doors will automatically lock and unlock most times lock and locks me in the vehicle having me have to climb through the windows and having to leave my windows open or locks me out the vehicle and can only get in by climbing in the trunk. Testing has been done and brought to GM to figure out the issue, and they replace the computer in it but still has the problem. I have had shops tell me these are all huge issues that needs to have a recall because my vehicle is not the only GMC Acadia that does all this. How is any of this safe for me and my kids.

SHIFT TO PARK WARNING. VEHICLE WILL NOT POWER DOWN.

The shift to park in my 2018 GMC Acadia was faulty. On many occasions and randomly, the car would be in park but would not turn off, saying I needed to shift it to park in order to turn the car off. This has left me unable to turn my car off resulting in dead batteries and missed appointments and being late for work. This defect is well documented by GM in TSBs PIT5616A, 18-NA-297, and 19-NA-206, which describes the exact symptoms and repair that I had to have completed. This problem has been on going and as a teacher I cannot continue to be late for school because my car, though in park, would not turn off. Given GM’s prior acknowledgement of this defect, I believe reimbursement is warranted. I have never been notified of a recall on this.

Shift to park- recall on 2017-2018 Acadia’s Started having issues several months ago- was occasional note constant. I see there has been a recall at one time and it is ac known problem. I am on my 2nd battery!

After shifting car to “P” park, it still says shift to park and drains the battery.

When I put my vehicle in park, the message “shift to park” pops up. It has been doing this for well over a year. I have already had to replace a battery once due to this because I didn’t realize it was still on. It does not happen everytime I park but at random times. The more it happens, the longer it takes for it to go off. At this point, I can only hope my car is really in park. I jiggle the shifter, hit the “ +|- “ on the shifter and have to turn the vehicle off and on about five or six times. Eventually it will go off. It took me 20 minutes today for it to go off in 100 degree heat. The vehicle’s AC is not running when trying to get the shifter to go off. It keeps the electronics running but not the AC. I keep waiting to receive a recall on this vehicle because of this issue but still nothing. I have noticed there is a recall for this but not vehicle. I have already replaced one battery due to this issue and do not want to continue to replace batteries and worry if the vehicle is really in park or not.

Battery saver ignited comes on and and the entire dash flickers and turns off ! This happened in a middle of an intersection and I could move my car. We jumped it and went to the nearest auto zone replaced the battery . It was pulling 89 amps . The next day it popped up again and we replaced the alternator. Upon replacing this there was oil everywhere! And we don’t know where it is coming from . Now shift into part light comes on !

There is a current recall on the 2018 GMC Acadia for a "Shift to Park" issue. It clearly states that GMC is aware of this issue and my vehicle is having this issue but for whatever reason, I am being told we are not part of the recall. My VIN is not coming up with it either but we are having the same issue.

Component/System: Transmission selector / electrical system (“Shift to Park” defect) Yes, vehicle is available for inspection upon request. I own a 2018 GMC Acadia. Since I purchased the vehicle used in June 2019, the car has frequently displayed a “Shift to Park” message even when the vehicle is in park and the gear shifter is fully engaged. This message prevents the car from turning off completely, leaving electrical systems running, the ignition on, and draining the battery. This issue has persisted nearly daily for the past five years. I brought the vehicle to a GM dealership in September 2020, while it was still under factory warranty, but the problem was not diagnosed or repaired at the time. The dealership could not reproduce the issue, but it continued regularly afterward. I am now paying nearly $900 out of pocket to have it repaired. Safety Risks: The vehicle does not fully shut down, increasing risk of electrical malfunction or battery failure. I am often unsure whether the car is truly “off,” which could pose a fire hazard or lead to the car rolling unexpectedly if the system misreads the gear position. This defect has also caused me to get stuck in unsafe areas, repeatedly turning the car off and on, jiggling the shifter until the system registers park. The constant battery drain has left me stranded with a dead vehicle multiple times. Reproduction / Confirmation: The issue has been reproduced by an independent repair shop and will be fixed at my expense next week. A GM dealership inspected it in 2020 but failed to diagnose or confirm the issue at that time. Inspection: The vehicle has been inspected by a GM-authorized service center. Not inspected by police or insurance representatives. Warning Messages or Symptoms: The “Shift to Park” message appears on the dashboard even after the vehicle is correctly shifted into park. This began shortly after purchasing the vehicle in June 2019, worsened over time, & still has the inability to turn off properly.

Shift To Park appears on the dash display also with a chime warning, when the car is physically in park and the engine is cut off. The shift to park display and the chime stays on causing a complete drain of the battery.

When putting my GMC Acadia in Park and shutting off the push start ignition the alarm goes off saying it’s not in park when it is clearly in park so I have to continuously start the car and try to keep putting it in park and shut ignition off. I googled it and saw there was a recall so took it to dealership but my vin was not included. I feel my safety is at risk as my battery also went dead stranding me in another city with my young grandkids on February 23rd, and I had a large bill to get a jump as well, I believe due to this same electrical issue! We are waiting on estimate now to get it fixed which is ridiculous as it is the same issue that is covered on many other of the same model vehicles! You should really look into this and maybe other electrical safety concerns costing consumers thousands of dollars on all these GMC vehicles it doesn’t seem fair. Thank you.

My vehicle has a persistent shift to park issue. My vehicle cannot be safely turned off. My vehicle needs to be restarted multiple times and the gearshift moved to the park position for the chance that it will register being in the parked position so the vehicle can be safely turned off.

The contact owns a 2018 GMC Acadia. The contact stated that while shifting the gear shifter into park(P), the "Shift to Park” message was displayed on the instrument panel. The contact was forced to shift from drive(D) to Park(P) repeatedly before the failure was corrected. In addition, the contact stated that while driving at various speeds, the steering wheel would become sticky with the "Steering Assist Reduced - Drive with Care," message displayed on the instrument panel. The contact stated while driving at various speeds, the infotainment system glitched and performed independent functions, causing the driver to be distracted. The contact stated that the infotainment system was replaced when the vehicle was purchased due to the failure; however, the failure recently recurred. The manufacturer was made aware of several failures and informed the contact that there were no recalls on the VIN. The vehicle was not repaired. The failure mileage was approximately 105,000.

Sold 2018 GMC Acadia by LEE GMC in auburn. Acadias shift to park was defective, dealership replaced before sale did not disclose, shift to park and transmission malfunctions occurred. I returned Acadia to the dealership several times and they would never properly fix or address my concerns now my vehicle is unsafe to drive. I have documentation to support the claims in my letter, I can send as well if you’d like. Thank you Will send attachment

When vehicle is put into Park I keep getting a "Shift to Park" message and cannot turn off my vehicle. I cannot lock the door.

Truck lost power randomly while driving on freeway spend so much money on fixing it this has to do something with the way the built it

We purchased our 2018 GMC Acadia, used with 15,798 miles on the odometer, on [XXX] from John Wiesner, Inc. On [XXX], with 20,344 miles on the odometer, we began experiencing a "Shift to Park" message when trying to turn the vehicle off, even though the vehicle shifter indicated that the vehicle was in park. Though the vehicle would turn off, we could not clear the "Shift to Park" message or stop the associated audible alarm without a great deal of effort. A Wiesner dealership confirmed the problem, determined that a switch in the shifter assembly was not grounding, and replaced the transmission control assembly under warranty. All was well until early 2024, at approximately 47,500 miles, when we began experiencing the same problem. The dealer said we must pay $500+ for a repair and that if we failed to get the problem repaired we risked being unable to get the vehicle into park and unable to turn off the vehicle. Being unable to stop the "Shift to Park" message or to stop the audible alarm at the very least will run the battery down and being unable to put the vehicle in park or turn it off risks an injury to us or others.

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 .

The contact owns a 2018 GMC Acadia. The contact stated that the vehicle failed to start and restart daily and required to be jumpstarted. Additionally, while the transmission was shifted into park(P), the "Shift to Park" message was displayed, and the vehicle failed to turn off, causing the battery to become drained. Roadside Assistance was able to jumpstart the vehicle. The vehicle was taken to AutoZone and Firestone, where the battery and alternator were tested; however, the cause of the failure could not be determined. The contact purchased a battery jump starter to jumpstart the vehicle. The vehicle was then taken to Pep Boys, where the alternator, battery, and starter were all tested, and it was determined that the engine switch had failed. Pep Boys advised the contact to take the vehicle to the dealer for a diagnosis. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was 81,737.

I purchased this car in May 2024 and it has done this since the day I bought it. When I shift into park and turn the car off it alerts me that I need to shift into park but it already is, I have to squeeze/jiggle the button on the shifter to make it stop. I feel this could cause some serious problems

When I park the car it beeps and displays on the dash to please park the car. Even if I have it on park. Won't allow me to turn it off. Finally turned it off. Turned it back on. And it done it agian..

Shift to park error notice comes up on dash when car it turned off and in park. Car is clearly in park, but error code “shift to park” appears on screen. Beeping occurs until car is turned off and shifted to R or D and then shifted back to park and turned off. This error happens several times a week, including twice today 6/22/24. I have to restart my vehicle and shift it to R or D then back to park SEVERAL times before the error is cleared.

GM has acknowledged that there is a "Shift to Park" problem with 2017 and 2018 GMC Acadia's. This design flaw/ part failure does not recognize that the vehicle is actually in "Park" so you cannot shut off the engine. In addition, the dash lights remain on which eventually drains the battery. Sometimes the car will roll as if it's in Neutral. GM is very aware of this problem. However, they do not have a permanent solution. GM should be required to issue a nationwide recall to correct the situation by totally disabling the electronic part. In six years of ownership, I've encountered this problem 3 times: 5-14-19, mileage 13,266, 1-27-21, mileage 29,381and most recently 5-30-24, mileage 65,057. This 3rd repair cost me $721.88.

Seemingly at random a warning will pop up on the driver dashboard “Steering assist is reduced at this time”. This will lead to a engine coolant temp reading of 0 degrees, no a/c and reduced steering functionality. Through further investigation the OBD code P0128 tells us it’s a faulty Thermostat or Thermostat sensor. Even if you get these parts replaced, the issue still comes back. I’ve seen these exact complaints at least a thousand times across multiple years of this model/make 2016,2017,2018,2019. This is clearly a manufacturers fault and needs a recall before people get hurt.

The car needs an PCM upgrade because it’s lit up a code in randomly situation. Causing the vehicle to lose the water temperature gage, power steering wheel assistance reduced and ac stop working, gmc is aware of the problem even issued a technical bulletin in 2018, but instead of inform the clients about the defective part, they want the client with this problem to pay to upgrade a defective PCM that came out from factory with problem. Note the power steering wheel assistance is part of the safety of the car. The problem always existed in the car, it toke me 2 years to find the problem.

I bought a used 2018 GMC Acadia in Oct. 2023. Initially the thermostat would go out and a check engine light would come on. This seems to be a common problem in GMC Acadia's and there are multiple blogs on this online (e.g. [XXX] ). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Thermostat fails frequently leading to reduced steering assist and temp gauge drops to below cold while fan runs on high. Along with sporadic blackout on all interior screens/instrument panel.

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.

Numerous occurences especially recently of shift vehicle to park when vehicle has been parked, turned off and already shifted into park position. Several occurrences where almost every time within 24 hours I use my cruise control and air conditioner at the same time my check engine light will come on as well as the stability trac indicator which then causes my air conditioner not to work and inability to start the vehicle due to having a check engine light on.

The thermostat stops working and my a/c stops blowing cold air, and driving assist stops and engine light goes on. It is a rampant problem among GMC Acadias with no reason or fix. Please advise.

2018 Acadia will display “Shift to park” warning along with an audible warning when the vehicle is shut off. This happens even though the PRNDL display is in the “Park” position each time. If I try to exit the vehicle, the audible warning continues (apparently indefinitely). This began at an odometer of about 59,200. Initially, the situation could be corrected by restarting the car and shifting in and out of Park or depressing the shift knob several times. Within a couple of hundred miles, it became consistent and eventually could not be corrected as described above. Unfortunately, this is not covered under warranty. I began driving for a few months without the shift knob, simply depressing the plunger on the shift rod coming up from the transmission. Doing this, the warning rarely occurs and, if it does, it’s easily corrected with one or two presses of the plunger. Some modifications of the shift knob have allowed the knob to be used with results similar to driving without the knob. I hope there will be a software update (deployed over OnStar) to use the PRNDL information and eliminate this failed system.

For months after putting car in park it displays a "Shift to Park" message. It won't let you fully shut down vehicle. Some times I can start it again, back up a little, put it back in park for it to shut off. Not one time though. You have to do it repeatedly. Maybe 6 or 7 times before it works. Most times I just finally have to walk away from the vehicle. Problem being it won't let me lock my car - which the police in our area keep warning us to do to prevent the vehicle thefts. It also continues to 'bing', running down the battery, which could leave me stranded somewhere. I looked this up on line assuming it would be a recall because it is a 'known defect' and there are thousands of complaints on line of people having the same issues and dealer won't take care of. There are lawsuits. This should be a recall.

The contact stated that upon inspection, the liftgate was closed. The contact stated that after parking the vehicle, the liftgate failed to latch securely and a bungy was used to keep the liftgate closed. The contact stated that the dome light illuminated indicating that the doors were open; however, the doors were securely closed. The contact stated that the roof light was turned off and the radio failed to operate. The vehicle was not diagnosed or repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 200,000. The VIN was not included.

When shifting the car into Park the P lights up and the car appears to be in Park, but an alarm goes off when you press the stop button to turn the car off. Action Required : Shift into Park. You have to restart the car and move the shifter or press the button on the shifter to get it to recognize that the car is in Park. This has gotten worse, last time it took over 20 minutes to get the car to recognize it. I have the car scheduled to go to the shop tomorrow. Warranty has expired due to date. Car only has 17,760 miles on it. 05/27/2022 was the last time the car was driven. I am sure they will try to charge me for this. It is a known issue and there seems to be a class action law suit over it. TSB - 19-NA-206 Dated September 2019. This should be a recall.

Vehicle does not recognize when in park, safety issue as passenger or driver could step out of vehicle while still in reverse. Unable to shut down vehicle due to not recognizing vehicle is in park.

Shift to park warning when parking and shutting down vehicle. Shifter is in park but will not shut off electrical system of vehicle.

Shift to park switch is defective. Switch will not register transmission is in park causing an alarm that runs battery dead. Car has set in my driveway 3 months unable to drive.

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!

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!

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 VEHICLE INTO PARK AND THEN TURN VEHICLE OFF. WARNING LIGHT COMES ON WHICH SAYS "SHIFT TO PARK." TURN VEHICLE BACK ON. MOVE SHIFTIER FROM PARK TO DRIVE AND THEN TURN VEHICLE OFF AGAIN. WARNING LIGHT COMES ON AND WARNING "SHIFT TO PARK." DO THIS A FEW MORE TIMES AND IT FINALLY THE WARNING STOPS. IT DOES THIS INTERMITTENTLY.

The contact stated while parking the vehicle, the gear shifter was shifted to the park position however, the gear shift indicator failed to show that the vehicle was in park. There were several attempts made before the shift indicator showed that the vehicle was in Park. The vehicle was diagnosed but not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 44,000.

I have numerous warnings, shift to park, steering, cross traffic, this endangers myself and anyone else around me, i have read several class action suits involving these problems and it could cause my vehicle to pose a danger, I have taken my vehicle in to a certified dealer and they state there is no known recalls associated with my vehicle which is strange because GMC knows that there are thousands of vehicles having the same problem, did I buy a lemon? These problems are clearly manufacture related and in no way normal wear and tare. I should not have to compensate these issues when I paid near 40,000 for it

WHEN I PUT MY CAR IN PARK AND TURN OFF IT WILL RANDOMLY SAY "SHIFT TO PARK" IT STARTED DOING THIS IN AUG OR SEPT 2019 THE CAR WAS UNDER WARRANTY AND I BROUGHT IT TO A DEALER TO "FIX". FAST FORWARD APRIL 2021 IT STARTED TO SAY SHIFT TO PARK AGAIN AND CAR IS NO LONGER UNDER WARRANTY. CALLED DIFFERENT DEALERS EVEN THE ONE I BROUGHT THE CAR TO FIX PROBLEM (THAT WAS A JOKE), THEY KNOW ITS A PROBLEM AND SAYING SINCE THAT PART GOT FIXED IN 2019 WITH A BAD PART AND NOW THERE IS A A NEWER FIX THAT SHOULD WORK BETTER, BUT I WILL HAVE TO PAY FOR DIAGNOSTIC TEST AND PART AGAIN. AGAIN THEY KNOW IT IS A PROBLEM WITH THESE CARS AND IT NEEDS TO BE RECALLED. I HAVE TO TURN THE CAR OFF AND ON RESHIFT, PUSH THE SHIFTER HARDER, ETC TO GET THE MESSAGE TO GO AWAY SO I CAN TURN MY CAR OFF.

"SHIFT TO PARK" ISSUE. WHEN OUR 2018 GMC ACADIA IS PLACED IN PARK, THE DIC DISPLAYS THAT THE VEHICLE IS NOT IN PARK WHEN IT IS INDEED IN PARK. NEVER SURE IF TRANSMISSION IS TRULY IN THE PARK POSITION AND CANNOT ROLL, BUT THERE IS NO CONFIRMATION OF THIS.

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.

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.

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.

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. WHEN SHUTTING OFF THE VEHICLE AFTER YOU HAVE PUT THE VEHICLE IN PARK ON THE GEAR SELECTOR A MESSAGE COMES UP ON THE SCREEN THAT SAYS SHIFT TO PARK IT HAS TAKEN UP TO 20 TRIES OF SHIFTING THE VEHICLE IN AND OUT OF PARK UNTIL PARK WILL ENGAGE. AS YOU CAN SEE IN THE PICTURE ALL GAUGES ARE AT THEIR LOWEST POINT SHOWING NO POWER TO THE VEHICLE AND THE SHIFT INDICATOR IS IN THE NEUTRAL POSITION WITH THE MESSAGE ON THE DISPLAY READING SHIFT TO PARK.

VEHICLE ENGINE WAS RUNNING WHEN I CAME TO A STOP AND SHIFTED TO PARK. I RECEIVED AN ERROR INDICATING "ACTION REQUIRED - SHIFT TO PARK." I DID NOT LET OFF OF THE BRAKE PEDAL BECAUSE I WAS UNSURE IF THE VEHICLE HAD ACTUALLY SHIFTED INTO PARK. WITH THE BRAKE PEDAL APPLIED, I ATTEMPTED TO SHIFT TO NEUTRAL AND DRIVE, THEN SHIFT BACK TO PARK, AND RECEIVED THE SAME ERROR. WITH MY FOOT STILL ON THE BRAKE, I TURNED THE IGNITION OFF, BUT THE ELECTRONICS WOULD NOT POWER OFF AND THE ERROR CONTINUOUSLY DISPLAYED ON THE DASH. I STARTED THE ENGINE AND REPEATED THIS PROCESS MULTIPLE TIMES WITH THE BRAKE PRESSED BEFORE CHANGING GEARS AGAIN, SHIFTING INTO PARK, THEN APPLYING THE ELECTRONIC PARKING BRAKE WITH THE ENGINE RUNNING. IT WAS ONLY THEN THAT I TURNED MY ENGINE OFF AGAIN, AND THE ERROR FINALLY NO LONGER DISPLAYED. SINCE THE ERROR WAS NO LONGER DISPLAYING, I COULD ONLY HOPE THAT MY VEHICLE WAS ACTUALLY IN PARK, BUT FELT REASSURED THAT THE ELECTRONIC PARKING BRAKE WAS ENGAGED. PLEASE INVESTIGATE THIS SAFETY CONCERN THAT SEEMS TO BE AFFECTING MANY OF THESE VEHICLES.
