What 97 owners told NHTSA about the 2020 GMC Acadia Limited

After driving 5 miles up the road and 5 miles back home, I put the vehicle in park and it automatically went into neutral and the neutral button started flashing! Along with that I got an alert sent to my iphone (through the GMC app) and in the car saying “shift to park”. The car wouldn’t go into park! The vehicle hadn’t had any error codes or messages before this at all! It was out of nowhere! I drove it earlier that day and it didn’t do it! We also noticed after doing the update on July 7th, 2022 that the vehicle started shifting very hard! I was in the vehicle alone with 2 small babies and I couldn’t cut the vehicle off because it wouldn’t go into park! We had to wait for my husband to leave work and come home to unhook the battery just so we could get out of the car safely and so the battery wouldn’t go dead over night! The following morning we hooked the battery up and the vehicle wouldn’t turn over at all! We just bought this vehicle from a dealership in October 2021! We haven’t had it even a year yet and after researching our year make and model to see what was going on.. we have realized that almost every year from 2019 back had a recall concerning the “shift to park” error! I have been almost 2 weeks without a vehicle while it’s been at the Chevy dealership and it took 5 days for anyone to even contact me! It makes no sense and now they are saying that they can’t tell if it’s covered under my power train warranty because they can’t crank the vehicle to see if I’m within my 60k miles of the warranty! (Which I am.. my mileage is 47,204) This happened to my vehicle on 7-12-2022! I would love some feedback! I am glad I was home and not somewhere stranded with two babies on my own with this heat being so hot!! My email is [XXX] My phone number is [XXX] Thank you so much! I appreciate everything-needless to say I am not a big fan of GMC right now! [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

While driving, the power steering went out and a service power steering message appeared. I turned off the vehicle and waited a few minutes and when the car was turned on it went away and the power steering came back.

I noticed for months it was downshifting hard but transmission department was backed up I scheduled in September for an appointment October 26 and that morning I received a call to reschedule because they were still behind and had another appointment for November 10th. The morning of the incident 1st it did not want to start it would only turn over. When it started the check engine light was on (I called service he asked if I could drive it and told me to bring it in). Within 10 miles of driving, the car started to slow down. When I pressed the gas the RPMs would go up but the car would not accelerate. I was on the interstate so I started to coast to the side. When I got to the other side of the rumble tracks the fuel gauge warning came on saying no fuel (even though I had half a tank which was verified through the service department) and the car came to an abrupt stop. Had I not gotten over when I did the car would have stopped on the highway. I tried to turn it on to move it farther off the road and it would not. It started to just turned over like it did when I originally tried that morning (all over the occurrences happened while I was on the phone with Adrienne who i contacted through the gm help line).

The vehicle was purchased brand new from Serra GMC in Washington Michigan in April 2020. It has been back to the dealer 5 times for the same issue, with another 4 times that it was not taken into dealer! Reoccurring issue involves the instrument cluster, All gages and visual indicators go to zero (speed, tach, fuel, temp, etc...) as well as getting a notification that the traction control is disabled, the ABS is disabled, cruise is disabled, and other electronic aid. This happens at highway speeds and to loose all function is a safety concern, it is not repeatable and happens randomly but it is the same issue. The dealer claims to fix the issue but it always comes back. GM has told me to accept the issue as its not detectable however this is unacceptable as it puts my family at risk. I have videos of the instrument cluster going to zero but its to big to attached - I can provide it if you contact me or tell me how to share it

The backup and surround view cameras repeatedly fail. I took it in once and they replaced the head unit. The problem reappeared within days after this repair. The design of this truck makes visibility without the cameras difficult at best and dangerous at worst.

The ACADIA 2020 while in slow motion approaching my private condominium parking spot, accelerated autonomously and then slammed into the cement wall. Airbags deployed, no warning of collision, seriously damaged both car and cement wall. No bodily injuries. I researched the possible cause coded P2138 which involves the drive by wire sensors which connect the throttle pedal and the CPU that controls the mechanical throttle gas system. That might be the cause of the autonomous acceleration like explained about the P2138 sensors issues.

TRAVELING AT HIGHWAY SPEED AND HAD A CATASTROPHIC LOSS OF AIR SUDDENLY AND WENT FROM 40PSI TO 0 PSI IN ABOUT 15 SECONDS. OCCURRED ON PASSENGER SIDE REAR. UPON INSPECTION OF TIRE NOTHING WAS FOUND IN EVIDENCE TO HAVE CAUSED THIS FAILURE. TWO DIFFERENT AGENCY'S EXAMINED TIRE AND SAID IT WAS IRREPARABLE. IN DOING SOME RESEARCH ON THIS FOUND THAT THIS BRAND OF TIRES - CONTINENTAL CROSS XL SPORT CROSS CONTACT MODEL HAS BEEN INVOLVED WITH A RECALL FOR OVER CURED TIRES CAUSING SUDDEN LOSS OF AIR. BOTH THE DEALER AND GM STATED THAT OUR TIRES ARE NOT INCLUDED IN THIS RECALL. WE WERE DRIVING ON THE PARKWAY AND HAD NOT HIT ANYTHING OR RAN OVER ANYTHING TO CAUSE THIS. WE FEEL THAT THESE TIRES SHOULD BE ALSO PART OF RECALL. WE ARE REPLACING THE OTHER THREE TIRES ON THE VEHICLE AS WE DO NOT FEEL SAFE DRIVING WITH THOSE TIRES.

PURCHASED NEW 2020 GMC ACADIA DENALI IN DEC 2019. VEHICLE WAS EQUIPPED WITH SEVERAL DEALER ACCESSORIES INCLUDE ROOF RAIL CROSS-BEAMS. THESE WERE NOT IN STOCK AT TIME OF PURCHASE AND RETURNED AFTER 1 WEEK TO INSTALL. AFTER PICKING UP THE VEHICLE ON MY DRIVE HOME, I HEARD A WHISTLING/HUMMING NOISE COMING FROM THE EXTERIOR AT ABOUT 30 MPH. AS I ENTERED THE HIGHWAY AND TRAVELING AT 65 MPH, THE NOISE WAS DEAFENING AND THE VEHICLE DID NOT HANDLE VERY WELL, VIBRATION IN THE STEERING. I IMMEDIATELY RETURNED TO THE DEALER AND DETERMINED THE NOISE WAS FROM THE ROOF RAIL CROSS-BEAMS. SERVICE TEAM THAT THERE COULD BE SOME NOISE BUT IT WOULD NOT AFFECT THE VEHICLE HANDLING. I HAD THEM REMOVED AND THE DRIVE HOME HAD NO ISSUES. BUYER BEWARE IF YOU ARE ONLY GETTING THE CROSS-BEAMS AS AN ADDED ACCESSORY AND WILL NOT UTILIZE TO CARRY ANY ITEMS, IE; KAYAK, BIKES, ETC.

RECENTLY PURCHASED A 2020 ACADIA DENALI. WHEN PARKING AT ANY INCLINE THE PARKING BRAKE AUTOMATICALLY TURNS ON. DEALER IS NOT SURE WHY, BUT NO WHERE IN THE MANUAL DOES IT STATE THIS IS NORMAL. TO DISENGAGE BRAKE VEHICLE HAS TO BE PUT IN GEAR WITH FOOT ON BRAKE TO TURN OFF. THE PARKING BRAKE SHOULD TURN OFF WHEN VEHICLE IS IN PARK WITH FOOT ON BRAKE BUT IT DOES NOT. DEALER IS UNSURE OF ISSUE AND HAS AN OPEN CASE WITH GMC TO INVESTIGATE.
