The 2020 GMC Acadia is supposed to be the higher-end model related to the Chevy Traverse. This upgraded model is designed to provide more technology, better comfort and helps owners to “travel safely,” according to the automaker. However, the defective electrical system, malfunctioning fuel system, dangerous brakes, and a faulty camera make that nearly impossible.

Most Common Problems with the 2020 GMC Acadia
In terms of the numbers of complaints filed with the National Highway Traffic Safety Administration (NHTSA), electrical system issues top the problems owners have. These include issues about the rear-view camera (RVC) failing. There is an open Office of Defects Investigation (ODI) in progress, so this is a major issue.
Problems relating to faulty brakes come a close second, which of course also relates to vehicle speed control. The fuel/propulsion system is creating problems for 2020 Acadia owners too.
Problems with the Electrical System
A properly running electrical system creates a seamless operation from the time the engine is started until the owner reaches their destination. Yet, with the Acadia, there are too many complaints that discuss trouble with this vital system.
Here is one from Cars.com. “The infotainment unit still has problems. Mine was leased on 1/18/20 and to date (today is 2/14/20) it has been in the shop 4x for issues surrounding the infotainment unit. First it had no sound when using remote start, then the cameras went out, then a fender popped loose, and the cause of the cameras going out was a frayed coax cable. Great build quality GM! The no sound issue they couldn’t figure out so I got a new infotainment unit installed. Out of the near month of having this vehicle, I have only had the chance to drive it for maybe a week.”
Beyond the infotainment system, GMC acknowledges other electrical system problems. Service Bulletin #070604025M also talks about various clicking and ticking noises coming from the vehicle. However, GMC claims that these sounds are a “normal characteristic.” It must come as a surprise to purchasers when they first drive their GMC SUV only to find out that it comes with some free noises that were unexpected.
Problems with the Fuel System
The Acadia’s fuel system is supposed to accurately supply the engine with the gasoline needed to get from Point A to Point B, but there are some major defects with the operation.
Read this NHTSA complaint. “Driving along no issues, car says 60 miles to empty no fuel warning light or anything, when car just suddenly loses power, was able to get to side of road. Told me to restart engine and it wouldn’t fire back up. Put a gallon of gas in and it fired back up. Owned car for almost 3 weeks, can’t believe there was no indication fuel was apparently that low. 60 miles to empty should have been able to finish the 2 miles I had on my drive to work and to get gas.”
Beyond the fuel system indicator, there are even larger problems occurring with the Acadia. Service Bulletin #16NA383 states that an updated fuel injection cleaner kit is needed to decarbonize the intake valves to correct a rough idle, trouble with starting, an extended cranking situation and misfire. The automaker also goes on to tell customers that they should use better fuels to prevent these problems. So, not only do they have to pay a premium price to get behind the wheel, but it appears that they have to spend more at the pump too, just to fix GMC’s problems.
Problems with the Brakes
The brakes of a vehicle are one of the most essential safety features needed. Yet, the Acadia is struggling to get the basics down.
Another NHTSA complaint says, “The contact owns a 2020 GMC Acadia. The contact stated that while driving at 15 mph, without warning the parking brake engaged independently. The contact manually released the parking brake and the vehicle operated as intended. [Dealer] was contacted and informed of the failure. An appointment was scheduled to have the vehicle diagnosed which was still pending. The vehicle was not repaired. The manufacturer was made aware of the failure, but no further assistance was provided. The failure mileage was approximately 6,276.”
If an accident were to occur because of this failure, owners might be in trouble. NHTSA Campaign Number 20V446000 states that some vehicles might have a malfunctioning Roof-Rail Air Bag inflator. If it fails, this vital air bag might not deploy in an accident, leaving occupants at risk. Considering the Acadia is appealing to customers by claiming to help them “travel safely,” one would think that the company would make sure everything works right first.
Problems with the Camera
It doesn’t take complaints from owners of the 2020 GMC Acadia to realize that there are camera problems with this General Motor Corporation (GMC) mid-size SUV. There is an open investigation by the ODI that was launched on July 22, 2022, that confirms rear-view camera failure is a major problem.
As the investigation report filed with the NHTSA states, the failure of malfunction of the RVC results in reduced visibility of the area behind the SUV. This, in turn, can lead to an increased risk of incidents that could result in injury or damage to property when the SUV reverses.
In other words, it’s an accident waiting to happen. This is confirmed by the fact that the ODI opened its investigation “to determine the scope and severity of the potential problem and to fully assess the potential safety-related issues.”
For the record, the investigation doesn’t only affect the 2020 Acadia, it affects another five GMC vehicles including the 2021 Acadia and several Cadillacs.
According to the ODI, complaints received over a two-year period state that “the screen for the RVC is black, sometimes with a red triangle and a circle with a line through it.” Most are from owners that have vehicles with low mileage.
There aren’t many complaints from owners on the NHTSA website. But here’s what a couple of affected owners have said.
An Owner from Michigan States:
“Center console display does not start when you start (the) vehicle. Stays blank! This happens occasionally. Sometimes restarting will fix (it), other times not. There is no rear view camera when this happens. Not sure what else is affected, such as backup warnings.”
An Owner from Connecticut States:
“Navigation system stops working / all cameras stop working give a triangle with exclamation in the middle / radio also shuts down.”

| Description | 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. |

| State | NY |
| Description | 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.. |
| Category | Lane Departure: Blind Spot Detection |
| Date | Dec 15, 2022 |
| State | NJ |
| Description | 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. |

| Date | Dec 12, 2022 |
| State | IL |
| Description | 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 - 00 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 00. 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. |
| Category | Electrical System |
| Date | Nov 17, 2022 |
| State | PA |
| Description | 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. |
| Category | Forward Collision Avoidance: Automatic Emergency Braking |
| Date | Oct 21, 2022 |
| State | GA |
| Description | 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. |
| Category | Forward Collision Avoidance: Adaptive Cruise Control, Forward Collision Avoidance: Automatic Emergency Braking, Forward Collision Avoidance: Warnings |
| Date | Sep 05, 2022 |
| State | IN |
| Description | 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. |

| State | NC |
| Description | 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 parkâ€. 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). |

| Description | 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). |

| State | MI |
| Description | 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 |

| Description | 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. |

| Description | 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. |

| Description | 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. |

| Description | 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. |

2020 GMC Acadia SLT: 43087 miles
Today (9/24/2022), My vehicle would not disengage. I came outside to find my taillights all on. Someone could hop in, start it and go. It also started giving warnings about Tire Mount system, no remote detected, No gas even though I filled up day before, A/C going on and off, signals don’t work, Door Switch malfunction, Anti-theft device malfunction, back-up camera sluggish, back-up system not functioning. I had this vehicle in the shop numerous times about the mother board and had it replaced under the bumper-to-bumper warranty and the problems with it started back up but they refused to replace the mother board again so remote issues continued and now all this just today.
