2021 GMC Acadia complaints

The exhaust resonator failed only a few hundred miles after warranty (60,300) and not covered by dealer under warranty. It creates a noise and reduces power/performance, which could inherently create a safety concern. The vehicle was inspected by an independent service center. The following code for the rattle noise is PIT5863.

Service safety restraint system notice comes on constantly and disappears at random times.

The fabric on my headliner/ceiling is coming unglued or the clips are not holding it. It is a danger to my driving the car as it is continually loosening; which could potentially fall while I am driving the car. It is making an irritating squeaking noise which distracts my concentration from driving carefully. I took the car to Walker GMC in Alexandria, Louisiana. The mechanic and the service advisor both told me GMC has issued an instruction form on how to fix this problem as GMC has had complaints with this happening to the Acadias. I contacted GMC customer service. They will not let me know if they will cover the cost of the repair until I get an estimate. Walker is wanting to charge approximately $188 for the estimate. Since this is a safety issue, I am reporting this problem to your agency so that others may be protected and GMC will take care of this problem.

The contact owns a 2021 GMC Acadia. The contact stated that while reversing, the back-over prevention camera failed to display an image. The vehicle was taken to the local dealer who diagnosed that the back-over prevention camera was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in NHTSA Campaign Number: 22V709000 (Back Over Prevention). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 25,000.

Vehicle lost power and died during normal driving. Luckily it occurred on a low traffic road and not the interstate. Prior to this there were no check engine lights or other signs of failure or degradation in performance. Was unable to start the vehicle and had to have it towed to my local dealership for service. Failure was due to the Fuel System Control Module GM part 13543075. This part is currently back ordered nation wide and the dealership cannot give an ETA on part availability or repairs.

The car stopped working all of a sudden, I was driving the car with no issues that morning and parked & shut off car to go to my appt. I turned the car back on and worked fine as I was putting in my address on the GPS my car just stopped and shut off by itself. I pushed the start button and it sounded like it wanted to start but it wouldn't and the whole engine shooked. Called GM and car still under warranty had it towed to the nearest GM. They diagnosed it and said it was the fuel injector module that went bad. It's 2021 with only 23800 miles. After a week, just got it back for a day and now the cooling fan has a loud noise, check engine light on, coolant stays on C even after driving it more than 10 mins, ac blows hot air, I get an alert with steering assist is reduced and to drive with care.....seems like something is wrong with the thermostat.

My grandson used the safety restraint in the middle second row seat. He pulled the belt out to put it on and it would not retract. I have taken it to the dealership to have it fixed but there is a fee of $515 to fix it. I do not feel I should have to pay the since it seems to be an ongoing problem with the Acadia model. I purchased a 2018 model before this one and the same thing happened with the middle safety restraint in the second row seat. I have contacted GM and they informed me there is nothing they can do to waive the fee of fixing this defect.

The contact owns a 2021 GMC Acadia. The contact stated that the software update was performed under NHTSA Campaign Number: 22V709000 (Back Over Prevention). After the software was updated, the Lane Departure Assist system failed and was no longer alerting the driver when the vehicle was drifting into the other lane. The vehicle was taken back to the dealer who completed the software update however, the cause of the failure was undetermined. The vehicle had not been repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 17,700.

My 2021 Acadia digital dash goes out (completely black). I took it to the dealership on Friday August 25, as the issue was happening more frequently. I was told the software was not current. This was attributed to parking in a garage each night. Yesterday September 22 while driving, the dash again went out for a much longer timeframe (several miles). I called the dealership. Service was closing but was told by the receptionist that one of the sale people said to (1) park the car, (2) turn off the engine, (3) open the drivers door and leave open for 5 minutes to reset the system and everything should be fine. The black dash prevents the driver from seeing current MPH. I am uncertain if it also disengages adaptive cruise control and auto-braking. Is it acceptable for the digital dash to routinely go black while being operated? Is there a more sustainable resolution for the dash going out? Thank you!

The contact leased a 2021 GMC Acadia. The contact stated water had leaked into the trunk compartment on a rainy day. Additionally, the contact stated that he pressed the power release button to close the trunk; however, while the trunk lid was in the process of closing, the driver's side trunk lid spring fractured. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed nor repaired. The failure mileage was approximately 15,000.

Driving at 70mph on Interstate 69 near Charlotte Michigan at around 10 pm on Wednesday 8/23/2023. Passenger side front tire suddenly deflated. Limped the SUV into a store parking lot at interchange. Continental 235/65R18 106H tire was changed by road side service and spare installed. This morning , while examining tire and rim , found two long radial cracks approximately 50 to 75 mm in length on the outboard surface of the tire. The cracks are about 90 degrees apart. The vehicle has just under 34000 miles on the OEM installed tires. The reason I am contacting NHTSA is that the cracks do not look like road hazard/debris, rather a split in the sidewall. I have not taken the tire back to the dealer or a tire store. I did photo document the failure and cracks.

The IPC goes out while driving. GM is aware of this issue in several models they make starting in 2020. They failed to call a recall on the issue and when you take it in to be looked at there is a service bulletin out to have the dealership to do a software update on the IPC to resolve the issues that some customers may be experiencing. This issue costs 189.99 to diagnose the first hour then the dealership spends another 2.5 hours diagnosing the known issue to charge customers for a total of 3.5 hours in repair costs. GM does not assist in anyway with covering the cost of the repair to the vehicle that is a 2021 make and model. In all to make your car safe to drive again the repair costs 474.88 and there is no guarantee after the software is updated that the issue will not come back and then I will be left with taking it back in for troubleshooting to be charged another 474.88 as long as the price does go up for electrical diagnostics charges. It’s pretty convenient on GM and their dealerships to charge customers a to fix a safety concern that can happen again and charge 3.5 hours of labor charged even when there is a service bulletin out telling repair technicians to do the software update when a customer stated the IPC goes out while driving and comes back on. If there is a know. Issue then my issue should be been resolved with just having to pay for time it took the repair technician to do the software update. Not waste time tracing all wiring just to run up all labor rate

Car stalled on major roadway. Could not restart of shift to neutral. Car blocked traffic for 3 hours until tow. Faulty fuel control module was the cause. Car was almost hit numerous times by passing traffic.

I opened my power lift gate to load groceries in the trunk. It opened without issue. As I loaded the groceries the lift gate came crashing down on my head. This happened in the festival foods parking lot around 5:05 pm today (7/16/23). Once I moved out from under it I saw the left arm was popped off. I popped it back in , there is a metal piece that was messed up. It came/ happened out of nowhere. I’ve never had an issue with it.

I have a really loud buzz & rattle noise. I can feel vibration on the passenger floor board real bad. The loud noise usually around 2,000-2,500 rpms. I have 39,000 miles on my car. It has always made a noise at take off but we thought it was normal untill now it's extremely worst. I took it into the dealship they diagnosed as something broken inside the muffler / resonator / weld inside muffler. So I did my research on the internet and I see alot of people complaining about this same issue on there cars. There was even a BULLETIN NUMBER (PIT5863) Pulished on 11/2/2021 the correction review # (21-na-118) all my issues are identical to bulletin. My year,make,model and issues with my car.

Breaks make loud noises when cold. OEM PADS and ROTORS. New with 8k of miles

Brakes will start Grinding on front wheels

Was driving when the vehicle engine completely lost power. Very dangerous situation in heavy traffic. Had difficulty pulling to the side of the road and ended up blocking traffic. Vehicle needed to be towed and is less than 2 years old with less than 10k miles. Diagnosis is failure of fuel pump control module. I see there is an identical GMC Acadia incident already logged by someone else and the dealer said they have seen this multiple times. After 1 week at dealer, they are unable to secure part for repair and don't know when they will. A RECALL was issued for other GMC 2021 vehicles for this exact problem. GMC RECALL N212332040: POWER CONTROL MODULE MAY CAUSE FUEL PUMP FAILURE. However this recall does not include the Acadia. The Acadia needs to be recalled as well before people are killed and the replacement parts need to be made available.

Vehicle has previously been brought in to GMC dealership at least 2-3 times for the dash turning on and off while driving. Started happening around 5,000 miles here and there. First took it in just over 7,000 miles as it was happening more and more frequently. It was last in for the issue on 2/6/23. The dash turned completely off WHILE driving going approx 45-50 mph, is not turning back on, unable to see speed while driving.

GM recall N222378380 Vehicle was taken to dealer for the recall for "Surround Vision". Dealer performed the recall yet the backup camera continues to work intermittently. Not having a reliable back up camera is a serious safety concern.

The vehicle was traveling at a very low speed in a parking lot and impacted a light pole. All front airbags deployed and the drivers steering wheel airbag deployed severely breaking the drivers arm, causing shoulder injuries, and neck injuries. The occupant would have been completely fine had the airbags not deployed.

Taken from service report; customer states brake pedal some times sinks to the floor and brake fluid on driveway. Tech performed brake fluid check and found that the brake fluid leak is coming from the left front and right front caliper hose, caliper hose has rub marking, making contact with cv boot. Tech replaced the left and right front brake caliper hoses and performed brake fluid fill and bleed, rechecked the operation of the brakes-brakes are working as design Also on service report: Left front cv axle leaking, left front outer cv axle boot is torn, replaced the c axle assembly. Not on the report is that the service manager Informed me that I should not have driven the vehicle in but had it towed in. Service performed under warranty at Linus Cadillac Buick GMC, Vero beach, Fl

The contact owns a 2021 GMC Acadia. The contact stated while reversing out of her parking space, the contact heard a squeaking sound coming from the brakes. The vehicle was taken to an independent mechanic and the brakes were replaced; however, the failure persisted. The dealer was contacted and stated that there was an upcoming recall and to wait for the recall. The manufacturer was contacted and stated that the vehicle needed to be diagnosed. The vehicle was not repaired. The failure mileage was 26,000.

While driving down a busy road automatic braking engaged for no reason causing the Acadia to abruptly come to a dead stop in the middle of the road with nothing in front of me. Red collision lights came on at the same time as braking with no prior warnings. Could not get the car to move for a few minutes (when giving gas there were grinding sounds) then the braking system let up. Drove for another few minutes and it did it again. Called GM and WE had to figure out how to get the car to the dealership with a major safety issue. Took the car in and it was throwing B390F, U0184, B395A codes. When we received the vehicle back one of the codes was for a bad back up camera so the new rear back up camera view is so stretched you can’t use it to back up nor does it have the lines anymore. The rear view camera now has a view that is sideways. So I took the car back to the dealership and they had no clue how either could be happening and would look into it again. Did my own research and figured out there are two cameras on the tailgate so the rear view camera was reinstalled wrong. Sent proof of how I came to the conclusion and that I wanted the backup camera replaced/fixed also. Its been over a month and I cannot get my car fixed because I refuse to pay for a rental on something they messed up because they have no loaners. Well on 11/14/2022 my cars automatic braking system activated again only this time it stopped in the middle of the road and was not as dramatic as last time. The wa

October 2022 Warning light service seat restraint system. Mileage 7180. Vehicle at Starling GMC Stuart FL for 2 weeks effective this coming week - Nov. 7. Airbag module issue again.

My brakes are awful. They sqeak and sqeal constantly. I've taken it to Ken Ganley Buick GMC several times. Prior to that, it was taken to Nick Abraham BMC. The dealerships are able to duplicate the sound and problem over and over again. None of the dealership representatives are able to offer a solution other than paying out of pocket to replace the brake pads because the material the brake pads are manufactured from are falling short. There is no way the brakes are functioning the way they were designed. Thankfully, I have not been in a situation where I need to slam on my brakes but I am not confident that they would do their job in an emergent situation. I have a toddler and a new baby on the way. I purchased a big SUV with the mindset that it would keep my family and I safe. We have leased several GMC products over the years and have never had an issue like this. We will absolutely not be renewing our lease to prove our loyalty to this brand. The fact that I'm being told the only way to fix the manufacturers problem is to pay out of pocket and fully replace the brakes on my vehicle that is 1.5 years old with 28k miles on it, is absolutely absurd. We are willing to give GMC the opportunity to make it right. At this point, I'll be honest, I doubt anything will even be addressed.

The contact owns a 2021 GMC Acadia. The contact stated that while driving, he heard a loud rattling noise coming from the exhaust. The contact then stated that the RPM’s increased and the rattling noise became louder. No warning light was illuminated. The vehicle was taken to the dealer where it was diagnosed that the exhaust resonator failed the whole exhaust assembly needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 28,000.

We purchased the vehicle in March 2021 and within a few weeks, the rear camera started working intermittently. At one point, it displayed a black screen with a red warning triangle. The dealership ultimately replaced the camera and we haven't had the problem since.

Make a left turn engine stopped. Fuel Pump Driver Module Failure. Electrical Short in module. Several fuses also blown. All dash warming lights stayed on. Vehicle had to be towed from middle of roadway. Battery also had to be replaced. Vehicle mileage 8100 miles.

As I was stopped in line behind a car at the ATM, my foot slipped from the brake, I quickly placed it back only to find that I ended up going forward. I quickly moved my foot more to the left for the brake only to end up going forward even faster hitting the car in front of me. I then put my left foot firmly on the brake. Now with both feet on the brake the car is climbing up the car in front of me and not braking. Finally, I put it in park and cut the engine. The whole front end of my car is crushed. Now 5 days earlier my husband had a similar incident when he was parking the car and thankfully only hitting the curb. Looking at the brake pedal you will find that there is a rubber edge hanging down on the right side. IF YOUR FOOT SLIPS BELOW IT while crossing from the accelerator going right to left, YOU WILL NOT hit the brake but will continue to press the accelerator. In fact, if you raise your foot upward, you will only raise the brake. The only way to get to the brake is to get out from under it by going toward the accelerator and then back to the left. This action does not work in an emergency! I believe this rubber edge is too large is a safety hazard. We are still in the process of assessment by insurance, body shop and GMC.

My emergency parking brake keeps engaging on its own, as I come to a stop, jeeking me forward. I never even put it in park, but it just engages the parking brake in a forceful manner. At a couple different times, while going at about 40 mph, the car starting shaking terribly, slowing the vehicle. The check engine light came on as well as both parking brake lights on the dash (the indicator light saying the parking brake was on and the indicator light saying there was a problem with the brakes). It felt light the vehicle had engaged the parking brake with I was driving and was dragging the parking brake. I have been having problems with the brakes with the vehicle and have taken it to the dealership a few times for this issue. They only kept it overnight and told me there was nothing they could do because it didn't happen while they had it. I have a fractured back and am disabled, and this issues actually hurts me when it does it.

While driving through intersection auto braking system activated for no apparent reason . Could have caused a crash due to sudden unexpected braking. No warning lights or alarm noted during or after event. Dealership was unable to find any problems with the automatic braking system.

I got into an accident because my back up crap camera did not warn me that a car had turned behind me. Also when and backing up and a car is coming it doesn’t indicate the car is coming until it’s behind me. I’ve taken it to the dealer and they say there’s nothing wrong with it. Also there is no break when you come too close to something in front of you.

The contact owns a 2021 GMC Acadia C1. The contact stated while driving approximately 40 mph, the parking brake engaged independently. The contact also mentioned having difficulties steering the vehicle. The vehicle was restarted and it resumed to normal. The vehicle was not diagnosed or repaired. No further information was available. The failure milage was unknown.

Brand new vehicle purchased from dealer, at 8900 miles transmission slipped. Dealer has for 2 hours and couldn’t find problem, but replaced transmission fluid it was dark. At 9000 it happened again, they have vehicle and said the new transmission fluid is dark and muddy. Only 100 miles, so they determined they need to take apart transmission and see what happened. It’s a 52k car, it should not be repairs, it should be replaced under warranty. Video of 8900 from dealership https://video.37483.net/timeline/2CJTHEW6

Was accelerating to approx 45-50mph when the vehicle gave no power, but my RPMs were revving. Once removing my foot off the gas pedal and trying to get power back, after the 2nd or 3rd time I resumed power. The car has less than 9000 miles on it. Right after, a message alerted me to have the vehicle brought in for service, and the engine light came on. According to the dealership, the found code P0700 which is normal, followed by P7224, something I am unable to locate anywhere online. They said they tested everything and all came back normal. It's been noted and if it happens again to let them know. I'm not feeling comfortable paying 50K+ for a vehicle to have it go haywire under 10K miles.

I want to voice my concerns with the windshield wipers, and storage placement. In winter weather conditions the storage compartment at the base of the windshield fills up with snow, even when driving. The wiper blades eventually end up resting on this snow. When wipers are turned on there is a quite often a build up of ice on the wiper blades. This causes the wiper blades to raise above windshield and not clean the windshield (partially or completely) Generally you need to stop and break/snow or ice from the wiper as you can not see. Same occurs when e get a freezing rain ice builds up at base of windshield then eventually ices up the wiper blades and not cleaning the windshield. The vehicle is not designed to handle winter and freezing rain conditions, after building vehicles for many years we should have a better wiper system. --Blades should have electric heat wires in them, --maybe need completely electric windshield to handle snow/ice cond. -- The placement of the defroster vents are very poorly placed, they should be all across the base of the windshield. A couple of days ago we had freezing rain, blades were freezing up, heater defroster was at max heat, and fan was at max, I had to constantly pull over and scrape ice off. This is very dangerous situation be it ice or snow. Design engineers really don't seem to take the winter conditions into consideration in the design of vehicles. I have driven over 5 million kms during my career and used to dealing with many types o

The contact owns a 2021 GMC Acadia. The contact stated while driving approximately 30 MPH, the vehicle started making an abnormal dinging sound. The contact stated service restraint system warning message was illuminated. The vehicle was taken to a local dealer where it was diagnosed with needing the SDM module replaced. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 21V702000 (Air Bags) however, the VIN was not included. The manufacturer was not informed of the failure. The failure mileage was approximately 16,000.

The contact owns a 2021 GMC Acadia. The contact stated that while driving approximately 30-60 MPH, the vehicle started shuddering inadvertently. There were no warning lights illuminated. The contact stated that he continued to drive the vehicle. The contact stated that the failure reoccurred while driving and the vehicle stalled. The contact was unable to restart the vehicle after several attempts. The vehicle was towed to the dealer who diagnosed that the transmission fluid needed to be replaced per the service bulletin #PIP5608H; however, the failure persisted. The dealer advised the contact to drive the vehicle for 200 miles and bring it back if the failure reoccurred. The contact stated that the vehicle continued to shudder and stall while driving. The vehicle was taken back to the dealer who diagnosed that the transmission torque converter needed to be replaced. The manufacturer was notified of the failure. The vehicle was repaired. The approximate failure mileage was 4,100.

Electronic parking brake is setting itself without you doing it even when parked on a completely flat surface. Voice activated assist is going off while driving down the road without you hitting the steering wheel button. 1st dealer I took the car to refused to even address issue because the car didn’t throw a code even though the parking break issue happened while in their parking lot. 2nd dealer at this point has had the car for a total of 16 days. They tried to tell me the parking break was normal, manager at actual dealership told me it definitely was not normal, and they don’t know what to do about voice activation going off. It has now been at dealerships 3 times for this issue within Oct and Nov 2021. Only 4,500 miles on car. If it is having these electric issues already what is in store for this car in the future? My husband has a video on YouTube of voice activated assist issue so far 2 other people are saying their cars are having the same issue.

My 2021 Acadia just stooped working as COMPLETLY SHUT OFF. I had no power to contact OnStar or more importantly to put my 4 ways(Hazard lights) on to signal or warn other motorists that there is a problem ahead. I could not push the vehicle as it is locked in gear because of the termination of power. I have had this exact problem happen 3 times leaving me and my family stranded on a busy road with nothing working. On each occasion I have removed my family from the vehicle in fear of being rear-ended! This would not only cause an accident with harm or fatality to my family, but has put that same risk to other motorists on the road. When I have had the vehicle in the dealership (Champion Buick/GMC of Brighton) in which it needs to be towed, they have not been able to find or confirm this issue. The dealership has had the vehicle for multiple weeks with help and assistance of GM with also no resolution. This is a very intermittent issue and when it happens it is an extremely dangerous situation. The vehicle gives no warning except for a total shut down.

The contact owns a 2021 GMC Acadia. The contact stated while stopped at a stop light and depressing the brake pedal, the engine revved up with the RPM’s increasing up to 15,000. No warning lights were illuminated. The contact stated that the vehicle jerked and vibrated as the transmission did a hard shift. The vehicle was taken to the dealer who took the vehicle on a 24-minute test drive and no failure was found. The vehicle was taken to the dealer several times and no failure was able to be determined. The failure occurred several times. The manufacturer was notified of the failure however, no assistance was offered. The approximate failure mileage was 249.

On at least 3 occasions, my vehicle’s locks have malfunctioned and I’ve been locked out of my car with one incident being locked out in the rain. Upon approaching my vehicle and using the unlock button on the outside of my door, I was unable to access my vehicle. Then trying my key fob and app to unlock, with all attempts unsuccessful. The back hatch of the vehicle would open, so my daughter had to crawl through to manually open the door. Once the vehicle was started, once put in drive, the vehicle would not lock. As stated, I can confirm three dates this has happened and that I’ve contacted my local dealer. I am pretty sure it’s happened one other time but I can not remember the date. The dealer would only look at it once and could not find anything wrong because the problem did not happen in the short time my vehicle was there. I do have video of at least one instance that I can provide.

Brakes grind, usually after sitting overnight. It has happened on multiple occasions.

The contact owns a 2021 GMC Acadia. The contact stated while driving approximately 65-70 MPH, the driver’s side rear spring detached and almost caused a collision. The dealer was made aware of the failure and it was arranged for the vehicle to be towed to the dealer for diagnosis. The contact stated that the vehicle was towed to the dealer prior to the failure after the contact heard an abnormal noise coming from the rear of the vehicle. However, the dealer could not replicate the failure and the vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 12,000.

Since purchase of this vehicle in Dec 2020, the rear camera vision has been intermittent. I originally thought it to be driver problem however I am now told that there is a module that needs to be replaced and it is not available and possibly not being manufactured at the present time. As a result the entire Camera parking assist system is completely out of service with no information on when the module may be available to repair the issue. I believe this may be a Safety issue as backing up into traffic be it parking lots or roadways, this equipment is an essential addition to safety to other vehicles and pedestrians.

The contact owns a 2021 GMC Acadia. The contact stated that while his wife was reversing the vehicle, the accelerator pedal was stuck to the floorboard and the vehicle crashed into the garage wall. No medical attention was received. No police report was filed. The dealer was made aware of the failure and informed the contact to tow the vehicle to their location to diagnose the failure. The vehicle was awaiting a tow truck and had not been diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 2,500.

As I was driving down Interstate 65 in south Alabama on a drizzling rainy day, the sunroof made a very loud popping noise and then exploded, with shattered glass falling into my SUV. Luckily, I was able to keep my vehicle on the road without swerving and losing control. I closed the sunshade on the sunroof to keep the glass from continuing to fall in and drove home. There was no warning lights nor any indication that something was wrong with the sunroof. When I got home, I called the nearest GMC dealership in Pensacola, Florida to report the issue (850.637.8973). Jonathan Sparks handled the claim. He sent out team members to pick up the vehicle from my home. They first removed as much of the glass as they could to keep it from flying off and possibly hitting another vehicle behind them. They drove it to Pensacola, replaced the entire sunroof, and then brought it back to me. Documentation and pictures are attached.
