2020 GMC Acadia Complaint Log

Service indicator on the driver information center stating to service vehicle detection AKA blind spot alert the system has failed once already was taken in for repair to GM was repaired and it has now failed again and is going in for service on April 4th 2023

The contact owns a 2020 GMC Acadia. The contact stated that the front driver's side and front passenger’s side seat belt locking mechanism failed to remain latched. The contact stated that while driving, the seat belts would erroneously become unlatched. The vehicle was taken to the local dealer who diagnosed that the seat belts needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 35,000.

While driving the vehicle goes into Automatic Braking. It has stopped me while I'm driving or it will make a loud scrubbing noise as if I've hit the brakes quickly. It has happened over 15 or more times. I've taken to dealership and they are not very responsive to check into the issue I am having. It is a danger to me if I am on the Interstate with vehicles traveling at a high rate of speed.

15000 miles and already having transmission/torque converter shutter. In the shop now. Shutters in all gears and also while in cruise control at 70-75 + mph Dangerous when car won't shift.Dealer has confirmed this issue and has performed a flush. Problem still there and very noticeable. On star has reported these warnings and dealer confirmed codes.

Rear view camera stopped working as I was backing up and ran into a pole damaged my right rear wheel well and panel.

SIDE BLIND ZONE SYSTEM TEMPORARIALLY UNAVAILABLE message displayed in DIC, and system does not function. I can not rely on the system as it very often does this. This issue started on 12/08/2022. I feel that I am at risk of a crash as I rely on this system for blind spot detection. There are MANY forums that state that MANY other 2020 GMC Acadia's have this issue. I feel like this is a GM issue, and the consumer should not be left with the cost of any repair, if necessary. This is a safety risk and could result in death from a crash due to a failure of a safety system.

The vehicle’s lock/unlock feature is inoperable either via the buttons on the door inside the vehicle or via the key fob. There is no manual way to lock/unlock the vehicle from inside the vehicle. Driver and passengers could only exit vehicle via rear lift gate or thru the vehicle windows. Should driver or passengers have had mobility issues or not been able to crawl through the vehicle to exit via the tailgate, they would not have been able to exit the vehicle in the event of any emergency. Incident has happened on at least 3 separate occasions.

The Automatic braking assist feature goes off at times when there is no threat of hitting something. It happens when pulling into a garage and also on the road while driving. There have been several occasions when this happened and the car suddenly brakes which could have resulted in being rear-ended. The car suddenly brakes even if there is no danger of running into a car (or garage) in front of me. It has not been inspected (yet) but it seems to be increasingly becoming more of an issue lately. There were no warning lamps or messages just the sudden, hard-braking and loud noise/buzzing it makes when it happens. There have been several occasions but I'm listing the most recent one below.

Twice this vehicle has exhibited this behavior. The collision avoidance system would flash a red warning on the HUD showing that a pedestrian was in front of the vehicle with the vehicle brakes 'hard' engaging causing the vehicle to 'nose dive' even though there was no pedestrian in front of the vehicle. This is disconcerting to those inside the vehicle and potentially be a crash issue with any vehicle following to close behind my Acadia. This may be an issue with the sensors/software used by GM and thus a safety issue that should be reviewed.

Center console display does not start when you start vehicle. Stays blank! This happens occasionally. Sometimes restarting will fix, other times not. There is no rear view camera when this happens. Not sure what else is affected, such as backup warnings.

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).

Rearview camera is intermittently non-functional when placed in reverse gear, and shows a red triangle and red camera icon on the screen along with a circle and slash through it. See attached photo.

AUTO STOP enabled while stopped at a stop sign on an uphill incline, there is enough of a delay on restart that it lurches and jerks upon restart, cant be good for transmission and passengers. very much a nusiance.

I started receiving an error message that driver assist is reduced drive with car at 50k miles (i have an onstar diagnostic report and phone call made that day). It shut my car down and activated the parking break. I called Onstar at that moment it happened and they found nothing wrong with the car. It continued to happened several times after and each time I took it to the dealer they were unable to diagnose the problem. One time I was told there was a bulletin on it from GM, but not for the year of my car so they were not able to make the repair. When it finally started giving me the error all the time, they finally found it was the thermostat - $1600 and GM would not cover the part under warranty because I now had over the warranty miles even though it happened and was reported prior to that point. I have several people tell me with the same vehicle they too are having the problem - and it is costing each consumer $1600. GM knows it is a problem because it is all over the internet. There should be a recall and our costs reimbursed if we have had to make the repairs on our own.

GMC safety recall was issued in Sept. 2022. (N222378380) My backup camera (2020 GMC Acadia) has been going in and mostly out since Jan. 2021. GMC has yet to find a fix for this issue, about 4 months since the recall but almost a year and a half for my car. I have had it in for service 3-4 times and thy can't fix it. It is a safety issue as we depend heavily on the camera to back up and the front camera to avoid hitting objects. We have had a few close calls but no damage, YET. I have had numerous conversations with GMC and my dealer. I keep getting the same answers. They can't (parts, no know fix, whatever) and won't do anything to fix the problem. I have been without this highly priced option for almost 2 years. Someone needs to get their act together. this is too long of a time to have this problem still exist..

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.

The contact owns a 2020 GMC Acadia. The contact stated that while driving at various speeds, the vehicle was shuddering. No warning lights were illuminated. The vehicle was taken to a local dealer, where it was diagnosed that the torque converter needed to be replaced. The vehicle was repaired; however, the failure persisted. The contact stated that while starting the vehicle, and while driving at various speeds, a buzzing noise was heard coming from the engine compartment. The contact also stated that while driving at an undisclosed speed, the vehicle stalled with the anti-theft system warning light was illuminated and the vehicle lost motive power. The vehicle was able to be restarted; however, the contact stated that unknown alarm chimes were heard. Additionally, the liftgate opened independently and various other unknown warning lights illuminated, and messages were displayed. The contact stated that the vehicle lost motive power and failed to restart. The vehicle was towed back to the dealer however, the cause of the failure could not be duplicated. The vehicle was not repaired and remained at the dealer. The contact was made aware that the warranty had expired. The manufacturer was not made aware of the failure. The approximate failure mileage was 2,000.

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 contact owns a 2020 GMC Acadia. The contact stated that she was rear-ended by another vehicle at a high rate of speed while attempting to make a left turn. As a result, the front passenger seat fractured. The air bags failed to deploy upon impact; the contact hit her head and was knocked unconscious during the incident. The contact was taken to the hospital by ambulance and was treated for a hematoma on her forehead above her right eye. Her husband, who was driving the vehicle, was later treated for muscle pain in his back. A police report was filed at the scene. The vehicle was towed from the scene to an independent mechanic where it remained in their possession. The dealer nor the manufacturer had to be notified of the failure. The contact stated that the vehicle sustained significant damage; however, it had yet to be examined or deemed a loss. The vehicle had yet to be repaired. The failure mileage was approximately 10,000.

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.

The contact owns a 2020 GMC Acadia. The contact stated that while driving at various speeds, the brake was applied independently. The contact mentioned that the brake was operating when there was nothing in front of the vehicle. The vehicle was taken to a dealer where the cause of the failure was undetermined. The failure recurred several times. The vehicle was not repaired. in addition, the accelerator pedal was depressed, and the vehicle started slowing inadvertently. The contact stated that the vehicle was locked and needed to be in the park to operate however, once the accelerator pedal was depressed the failure recurred. The vehicle was towed to an independent mechanic. The mechanic experienced the failure with the vehicle. The vehicle was towed to the dealer however, a diagnostic test was not performed. The manufacturer was notified of the failure and provided a case number. The approximate failure mileage was 16,000. The VIN was not provided.

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.

FUEL GAUGE READS AT 3/4 OR 1/2 TANK AFTER REFILLING FUEL.

BRAND NEW VEHICLE. PURCHASED ON 10/30/2020. FRONT COLLISION KEEPS FLASHING A RED LIGHT IN THE TOP OF DASH THAT SHOWS UP IN WINDSHIELD. THIS HAPPENS WITH NO OTHER VEHICLES ON THE ROAD AT RANDOM TIMES. WHEN THE VEHICLE NEEDS TO STOP OR WARN YOU IT WILL NOT. IT WILL JUST LET YOU HIT A PEDESTRIAN OR ANOTHER CAR. WE NOTICED THAT THE SAME THING IS HAPPENING WITH THE REAR SAFETY CROSS TRAFFIC.

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

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.

TWO DAYS AFTER PURCHASING A NEW 2020 GMC ACADIA I GET AN ERROR ON THE DISPLAY "SD CARD REMOVED" ALONG WITH VARIOUS OTHER ERROR MESSAGES. DEALER TALKS TO GMC TECH LINE AND THEY ADVISE TO REPLACE RADIO. RADIO WAS REPLACED AND ERRORS BEGAN SAME DAY I PICKED IT UP. DEALER IS REPLACING RADIO AGAIN, BUT UNSURE IF THIS WILL FIX THE ISSUE. THE VEHICLE DOES NOT WORK AS INTENDED AS WHEN YOU PRESS THE NAV BUTTON VARIOUS ERROR MESSAGES POP UP AND NAVIGATION DOES NOT WORK.

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.
