2020 Gmc Acadia problems
The GMC Acadia is a crossover SUV manufactured by General Motors for its GMC division. The first-generation GMC Acadia shared the GM Lambda platform with the Saturn Outlook, the Chevrolet Traverse, and the Buick Enclave. The Acadia went on sale in 2006 as a 2007 model in the United States, Canada and Mexico. The Acadia replaces three of the 7- or 8-seater vehicles on the Buick-Pontiac–GMC dealership network, the midsize GMC Safari van, the GMC Envoy, and the Pontiac Montana SV6 minivan for the domestic market. As of 2009, the Lambda vehicles have replaced the Buick Rainier, Buick Rendezvous, Buick Terraza, and the GMC Envoy XL and then subsequently the GMC Envoy, Chevrolet TrailBlazer and the Isuzu Ascender. A Denali version of the Acadia debuted for 2011. In 2017, the second generation Acadia was repositioned as a mid-size crossover utility vehicle in order to compete within the growing midsize SUV market against the likes of the Ford Explorer, Edge, and the Jeep Grand Cherokee.
First generation (2007)
The Acadia represents GMC's entry-level truck-like CUV and is the first unibody vehicle from the marque. It is also GMC's first front-wheel drive passenger vehicle, and also the first such vehicle of any kind since the 1973-78 GMC Motorhome.
The Acadia has seating for eight and either front or all-wheel drive. With a 5,200 lb (2,359 kg) towing capacity, the Acadia slots between the GMC Terrain and the Yukon. The Acadia is the mid-priced Lambda model between the Chevrolet Traverse and Enclave.
In December 2006, all production and sales of the Acadia (and the Saturn Outlook) were temporarily stopped due to the engine mounts not having holes drilled to release accumulated water, as well as an issue with potentially faulty rivets in the load floor just forward of the vehicle's rear hatch. The assembly process was quickly adjusted, and dealership sales of the vehicles had resumed within days of the notice.
The first-generation Acadia was sold alongside its second-generation replacement as the Acadia Limited.

Common 2020 Gmc Acadia problems
The 2020 GMC Acadia has some common problems reported by owners, which include dead batteries, excessive engine noise, and stereo system issues. These problems are similar to other midsize SUVs from the same year, leading to average repair costs as the Acadia ages.
Dead batteries are the most widespread complaint from 2020 Acadia owners, showing up at around 5,000 miles. There are a lot of electrical accessories in the Acadia, and some of them may stay on even when the engine is off. Diagnosing the source of the parasitic electrical draw costs around $50, while fixing it can cost $5 to $250.
Excessive engine noise has also been mentioned by some 2020 GMC Acadia owners within the first 20,000 miles. The purge valve is a known weak spot in the Acadia, and can make a lot of noise. Replacing the purge valve, fortunately, is a quick process, only costing about $150 to fix.
Stereo system issues also show up on some Acadia models at roughly 1,500 miles. There are software updates available for the stereo, which improves reliability. Most dealerships will install these updates for free, while others charge around $50 for labor.
In addition to these issues, the 2020 GMC Acadia has six recalls, which is worse than some other midsize SUVs. The most serious recall covers missing bolts on the start/stop accumulator, which can cause the engine to stall. GMC will replace the bolts on affected models for free. Other recalls include the rearview camera, tires, roof rails, and fuel pumps. GMC will change out those parts for free, too.
It is important to note that the 2020 GMC Acadia is generally considered a reliable SUV, with no widespread complaints. However, it is recommended to avoid models from 2017-2018, which have a lot of transmission issues. Models from 2019-2022 are more dependable choices.
Does 2020 GMC Acadia have transmission problems?
The manufacturer previously released a GMC Acadia torque converter recall in 2020 due to missing bolts in the start stop accumulator endcap which could lead to a transmission oil leak. However, the 2020 recall primarily affects 2019-2020 GMC Acadia models, and is unrelated to the most recent recall.

FUEL/PROPULSION SYSTEM PROBLEM
- Date Of Incident: 2024-09-15
- VIN: 1GKKNMLS5LZ
- Components: FUEL/PROPULSION SYSTEM
- Summary: Once again (for the second time in a few months) the vehicle put me and my passenger in an extremely dangerous situation. We were driving down a 55mph country highway catching speed, somewhere around 45-50 mph and the car jerked so violently that it shook us even though we had our seat belts on. It then made a weird noise and felt like it was powering down so I stepped on the accelerator to try to bring it back up to speed and it sped up a little bit, jerked again (not as violently) and turned off. Luckily, since it was a country hwy and no cars were coming, I was able to coast into a driveway. I attempted to restart the car to turn around and go home but as soon as i put it in gear, it would shut off. I tried a few times and it would make a "tick tick, tick" sound but not start. I waited a few minutes and tried again and was able to get it to start, go in reverse and get back home. Once I got home it would not start again. Mechanic says it is the same issue and before, which was also part of a recall for this vehicle having to do with the fuel pump relay. I will be trying to tow this vehicle to the dealership for repair.
ELECTRICAL SYSTEM,ENGINE PROBLEM

ELECTRICAL SYSTEM,UNKNOWN OR OTHER,VISIBILITY/WIPER PROBLEM
- Date Of Incident: 2024-07-31
- VIN: 1GKKNLLS1LZ
- Components: ELECTRICAL SYSTEM,UNKNOWN OR OTHER,VISIBILITY/WIPER
- Summary: Rear-View Camera Failure: The rear view camera functions intermittently. While in Reverse, the screen goes black, with a red triangle and a circle with a line through it. This SAFETY ISSUE increases risk of incidents resulting in injury and/or property damage while the vehicle is in reverse. I understand there already exists a NHTSA RECALL (NHTSA Campaign Number: 22V709000) however, it states that only vehicles equipped with the optional Surround Vision feature are affected. My vehicle does not have the 360 Surround Vision (RPO UV2). but is experiencing the same SAFETY ISSUE!
FUEL/PROPULSION SYSTEM PROBLEM
- Date Of Incident: 2024-07-06
- VIN: 1GKKNMLS5LZ
- Components: FUEL/PROPULSION SYSTEM
- Summary: The car would not start. It would power on but would not turn over. We had it checked out by a mechanic who tested it and found that the fuel pump module was not operable. When he went to replace it, he found that the one he was removing was aftermarket so this issue had happened before, apparently, before we bought it. We bought it with only 24k miles so it needing to be replaced that early is concerning. And now at around 50k it had to be replaced again. Researching this issue, I have found many folks reporting similar situations. This needs to be investigated.

So many different problems all at once! I have been treated horribly during these issues by dealership and extended warranty company. Dealer had my car for 3 weeks ! They couldn’t figure out the problem. I sat there for 4 hrs sent me home told to come back for 9 mile test! Why in 4 hrs that wasn’t done. So again the unable to shift message back on! I get in my car it starts but won’t shift ! Dealer charged me 250 to tow to shop! When they said I’d be fine ! I had more issues again and again! I’ve been driving over 40 yrs no accidents. I bumped into someone during a huge traffic jam in Ohio! Braking didn’t work no warning even . I should speak to a lawyer and could explain more to a person on filing these complaints.

- Date Of Incident: 2022-01-18
- VIN: 1GKKNULS0LZ
- Components: UNKNOWN OR OTHER
- Summary: 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..
STRUCTURE,VISIBILITY/WIPER PROBLEM
- Date Of Incident: 2022-12-20

LANE DEPARTURE PROBLEM
- Date Of Incident: 2022-12-08
- VIN: 1GKKNRLS8LZ
- Components: LANE DEPARTURE
- Summary: 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.
POWER TRAIN PROBLEM
- Date Of Incident: 2022-02-21
- VIN: 1GKKNMLS5LZ
- Components: POWER TRAIN
- Summary: 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.
ELECTRICAL SYSTEM PROBLEM
- Date Of Incident: 2022-11-16
- VIN: 1GKKNXLS4LZ
- Components: ELECTRICAL SYSTEM
- Summary: 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.
FORWARD COLLISION AVOIDANCE PROBLEM
- Date Of Incident: 2022-10-20
- VIN: 1GKKNPLS6LZ
- Components: FORWARD COLLISION AVOIDANCE
- Summary: 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.
FORWARD COLLISION AVOIDANCE PROBLEM
- Date Of Incident: 2022-09-05
- VIN: 1GKKNXLS8LZ
- Components: FORWARD COLLISION AVOIDANCE
- Summary: 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.

I love my Acadia Denali! The size is absolutely perfect, with plenty of space and a third row without being massive. It’s good looking inside and out, and the interior is plush and high quality. There are lots of great safety and convenience features, and the Acadia with the V6 is one of the best riding family SUVs out there. It has plenty of power, and it is smooth and quiet. I couldn’t be happier!

I purchased my new 2020 AT4 at the end of July and have been driving it for 6 months, covering nearly 12,000 miles. So far, I absolutely love it! The AT4 is an off-road trim, so it looks rugged and tough, rather than like some sissy city-only SUV. Don't pay attention to the lame editorials that speak ill of this SUV or its off-road capabilities. Instead, consider your needs. Do you need to crawl over boulders, cross rivers, or bog through mud? If so, then you need a more aggressive 4x4, like a serious Jeep, Toyota 4Runner, or 4x4 pickup. However, if you live in a harsh winter area, like to snow ski, or need to reach a trailhead that happens to be on a crappy dirt road, the AT4 is more than capable. Some articles like to be critical of its ground clearance of 7.2 inches and make it sound like certain competitors have so much more at 8 or 8.2 inches. Have they looked at a tape measure lately? Really? One inch or less! Give me a break! They fail to point out that these competitors, though they are AWD, that's all they are. The AT4 has an Off-Road selector (along with 2WD, AWD, Sport, and Tow/Haul) that turns the AWD system into a more capable off-roader by engaging a twin-clutch system, providing more torque to wheels that are losing traction. I have personally found this system to work extremely well on three separate occasions, two being on deep muddy roads with some relatively steep inclines, and one in sugar sand. The AT4 performed beautifully! The AT4 gets the 3.6 six-cylinder engine married to a 9-speed transmission. At 310 hp, the engine is very strong, and the 9-speed is smooth as silk. You won't have any problem pulling out in traffic or passing. It can go from 0-60 in 6.1 seconds. With the trailer package, you can tow up to 4,000 lbs. In my opinion, the ride is very smooth, taking bumps and such very well. The cabin is very quiet, even at highway speeds. I have taken two trips, both of which were nearly 1500 miles and included some of that 'off-roading' I mentioned, and still managed a solid 23 mpg combined. And that's with me being notorious for having a heavy foot! For me, at 6ft, it's a great fit.At 210lbs, I find the seats to be very comfortable and supportive. They can be configured differently with seating for 5-7 people. The 8-inch screen is great and very quick, while the instrument panel is nice and easy to use. Air vents are abundant with large vents in front and four more in the ceiling to the third row. Storage and gadget holders are everywhere. In my opinion, the interior is very nice, not plush, but very nice. The Bose sound system sounds great, of course, with plenty of bass through the subwoofer. There are two areas I feel could be improved on. Firstly, it doesn't have driver seat memory. I really feel GM should have made that standard in the AT4 since it's just a step down from the Denali. Secondly, the gear shifter is an electronic push button/rocker switch which is fine actually once you get used to it, but I do have to agree somewhat with the critics on the placement at the bottom of the center stack. I do feel it would be more user-friendly if it was located nearer to the steering wheel area, maybe set vertically. So, like I said in the beginning, I am very happy with choosing this vehicle. If you are looking for a rugged yet comfortable SUV, and not needing a hardcore teeth-jarring off-roader, then I think it would be worth your time to take a good look at the new Acadia AT4.

This Acadia SLT-2 is a great fit in terms of size and comfort. The LGX V6 received Wards award for being one of the 10 best engines, and it's a refined and reliable 4th generation V6. The vehicle has a smooth ride and enough power to make your journey enjoyable. It's not as big as my crew cab, but it's a lot easier to park. I've had Suburbans and Avalanches, but this Acadia works perfectly for me. My wife has taken it over.

I have only had the 2020 SLT Acadia a few days but so far I love everything about it. It surprised me how quiet and smooth the driving is. The captain chairs are wonderful and the 2.0 turbo feels more than adequate. Overall, I give it 5 stars. The only thing I miss is the lane centering that came standard on other brands.

This vehicle is good looking and our new Denali has all the intelligent options. Make sure to have your sales rep go over how to set up all the functions you want to activate, that will save you a lot of time. My wife and I love our new Acadia Denali!

The 2019 Acadia SLT that we purchased brand new has had persistent issues with the gear shift since the beginning. Despite occasional problems at first, the issue has now become a significant inconvenience. When attempting to put the vehicle in park, it repeatedly prompts us to do so and continues to make a dinging sound until we start the car and move it, sometimes requiring multiple attempts before it finally registers as being in park.

The 2019 AWD has been a reliable car for me, with the exception of some transmission issues that have arisen after 2500 miles. The shifting has become noticeably worse at 9100 miles, with a noticeable brake-like sensation between shifts. However, the car's appearance and handling are satisfactory. The headlights are not as bright as I would prefer, but this was easily remedied by upgrading the bulbs. Overall, I would recommend this car with the caveat that there have been some transmission issues. It is fortunate that I have a lease, but I believe that these issues can be resolved with proper maintenance and care.

My family has been a loyal GM customer for many years. We were excited to purchase a new 2019 GMC Acadia SLT1, but unfortunately, our feelings quickly changed. With only 645 miles, it suffered a transmission failure that left us stranded 350 miles from home. When we were able to get it in for repairs the next day, they determined the problem was severe, and we needed to leave the car for a number of days before it was fixed. Needing to get home, we had no choice but to arrange for transportation and then come back later to pick up the car. Although GM made the repairs under warranty, we were disappointed that they did not reimburse us for the over $400 of out of pocket expenses we incurred as a result of the breakdown and return trip to pick up the car. Despite this experience, we remain hopeful that GM will take steps to improve their products and customer support. Thank you for your attention to this matter.

Despite the initial issues with the vehicle, I am confident in its potential. The dealership was able to fix the problem and I am grateful for their assistance. While there were some additional codes that were not addressed, I am optimistic that they can be resolved. Although the horn honked unexpectedly and the security system was activated, I believe these are minor issues that can be easily addressed. While it may not have been the smoothest start, I am confident that this vehicle has a lot of potential. I am currently weighing my options and considering the best course of action moving forward.

I leased the 2013 and 2016 Acadia Denali, and just last week, I leased the 2019 model. Unfortunately, it turned out to be a big mistake. I rushed into it without realizing that they had removed many of the features that I enjoyed in my previous models. For example, the front seatbelts no longer adjust to your size, which means that they constantly rub against your neck. Additionally, the outside mirrors are no longer power-operated, and the knobs on the dashboard look cheap. The roof is much lower, which makes it feel like you're driving a car, and the driver's seat is now uncomfortable and narrow. The interior has very little storage space, and the middle console is small. Although the vehicle drives decently, I'm paying a lot more money for a lot less. However, I have to say that the one positive is that it does drive decently.
