On 7/20/2025 the following warnings were displayed: brake system warning light (brake), abs warning light, lane keep assist light is white, automatic emergency braking disabled light stayed on, traction control system (tcs) electronic stability control light stays on. Messages: auto hold unavailable, service brake assist, service esc, service stability control: your vehicle may be hard to control in certain driving conditions, schedule service soon. On page 103 in the owner's manual the warning for the brake system warning light said driving with the warning light on can lead to a crash. Have the vehicle towed for service. I had it towed to a local GMC /Buick service department. My safety and the safety of others were put at risk if the car did not brake. Could have led to a crash. The problem has been confirmed by the dealer. They indicated the brake master cylinder needs to be replaced. ( 7/28/2025 I was told it was on back order, when available is unknown) warning lamps etc have been described above. I had just pulled into the driveway of a friend and got all the warning lights.

There is no manual door unlock for the driver or front passenger. I’ve contacted Buick and the dealership and they have verified in the event of an electrical failure or fire there is no way to unlock the front doors to exit the vehicle.

Anc module is faulty after hvac condensation entered the unit causing it to not work making all speakers nonfunctioning.

I was driving on the interstate and the car just shut off. I was on the left lane and cars were honking and tailing me as I was trying to get off. I could not get off on the left and had to drift across to the right side. Thank god it was downhill. I drifted to the exit and went off onto the grass. My safety was at risk to the fullest. I am very lucky I was not killed as well as my sister! it was the most frightening experience. The car was towed to pensacola step one dealership. The manager of service says it needs a new engine. The car is only 6 months old! no warnings until it shut off, the gas peddle didn't work and I don't remember what it said I was a wreck.

The catalytic converter has been replaced 3 times. The flex pipes has been repaired and replaced 4 times and the exhaust pipes has been welded on 5 times. The back tail pipe fail off while driving and had to be welded. The exhaust on this vehicle has given me many problems.

We have had spark plugs fixed twice in the past 4 months and they keep faltering. Both mechanics changed them.

We experienced a spontaneous sunroof explosion. Vehicle was towed to the dealership. Sunroof is being replaced under warrenty. The vehicle is presently stored underroof at barkley GMC, tuscaloosa, al. After the very loud explosion, I pulled to the side of the road and engaged on-star for a wrecker. There were no warning lights. . . Just a spontaneous explosion . . . Blew out the entire sunroof.

The dealership is unable to identify the failing component or system. The vehicle shuts off while driving above speeds of 60mph, which causes the power steering pump and power brake pump to fail. This symptom of shutting off while driving creates a significant life safety risk for the driver, passengers, and other motorists. The vehicle has been inspected by the dealership over 4 times in 3 months. Since the vehicle shuts off, there are no warning lamps, messages or other symptoms prior to the failure.

During a rainstorm water is entering the fuse box under the glove box and the carpet and padding underneath is soaking wet on the right front floor. When the fuse case was opened water started to drip out. The engine continues to run with the key off and the only way to stop it is to pull the ignition fuse under the hood. Unfortunately the battery died by morning and I could not get it charged for a few days. Now I have learned how to take the battery cover off which is located in the back of the car and remove the plastic covers under the mat so I can disconnect the battery so it doesn't run down. The rear wiper will not shut off now since this started. I am a 75 yr old widow and wonder how this problem has not been on a recall. It causes a very dangerous situation. I will try to see if I can get it into a Buick dealer this week and pray god it doesn't cost me an arm and leg to repair it. There are service bulletins on this problem and seems to be quite freqent yet I have not received any notifications from you. If this happens at night in a parking lot what am I to do? can the car catch on fire by not shutting off?.

Bracket holding exhaust pipes broke and I'm told it is a hazard. It is over $400 to fix it, I paid almost $6,000 for warranty service contract when I bought my car which doesn't cover it. It looks like this same problem is listed for 2019 but not 2020 which would have covered it if you would list it as a problem for 2020 also. [xxx} please review and hopefully others have let you know also. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My vehicle stopped in the middle of the highway and was unable to put in drive.

The car stalled and is stuck in park. It has electronic shift and if the engine doesn't run it has to be put into neutral manually. The Buick dealerships don't know how to do this and keep referring me to an obsolete video. One service representative suggested the manual lever is under the air filter housing but they cannot provide any information on this design, the car is stuck in a garage and cannot be towed. It is stuck in place.

The tailgate lifts up and then slams down violently.

The front exhaust got a hole and rusted through as in similar years. This exact issue is covered for both the 2019 and 2021 models of the Buick Enclave under a special coverage adjustment (n212356540 and n222385510), but not for the 2020 model. It would seem to follow that if the year prior and after both have this issue, then the middle year should also be covered under a special coverage as the problem had not been fixed. The vehicle is currently getting service done for this exact issue covered under the special coverage adjustments and poses an environmental hazard as the exhaust is not going through the catalytic convertor and dumping pollutants directly in the the air. The only warning was a rattling noise when shifting and according to dealership is most likely caused by the bracket coming detached and breaking off.

Bad timing chain at 141,000 miles.

Ignition not acting like it’s in the right spot like not starting when turning key it moves like it’s loose and turned off while driving.

Just bought SUV from mother in law and already replaced alternator last week.

The recall has been active on my vehicle for over a year now with no means of fixing the issue. I have contacted Buick dealerships in my area and they have stated they have no ability to repair the recall and do not know when or if they will be able to. I do not know what my options are as my vehicle is still financed through my bank but I do not feel safe driving it or having my children in the car.

Multiple times I have been driving along at interstate speed when the mirrors retracted in to the windows of their own volition without the pressing of the button. I contacted nimnicht GMC and scheduled a service for [xxx] of 2024 at their phillips highway location in jacksonville, FL for them to correct the issue. They stated they were unable to duplicate but did flash the computer with an update shown in TSB the vehicle was kept from the [xxx] until the [xxx]. I picked up the vehicle on the [xxx] from their lot and drove it home. On the [xxx] while driving it to work, I again had issues with the mirrors closing on their own 5 times in the matter of 17 miles more or less, including at interstate speed on the buckman bridge. Again, after keeping my vehicle multiple days, they were "unable to recreate the issue. " I received the vehicle back on [xxx] of may. Today, may [xxx], I again had the mirrors close and trained a camera at the mirrors while driving down the interstate and captured them closing on their own without any interaction with a person.

You will just be driving down the road and then get the check engine light, engine power reduced, traction control off, and service stabilitrak warning on the dash board. You can be going 60 and it will just shut down with no warning. It's been to the shop 3 times and the issue is still unresolved. This is highly dangerous and could cause an accident.

What does it mean when my car says service stabilitrak and service traction control? its main function is indicating that the traction system has been turned off manually to remind you to turn it back on when necessary. However, the stabilitrak warning light may also signal potential damage to vehicle components that allow the system to work effectively. Loss of power to engine, can't stear, feels like its about to blow up. It seems very usual for the Enclaves, traverses and acadias. And I had the same problem out of my 2014 traverse ltz.

We bought our car in 2021 and shortly after our car started pouring water into the driver seat from the ceiling. At that time we thought it may have been a cracked window window. Actually we weren’t really sure because we don’t use the sunroof or anything really. However, it stopped doing it until around October 2023 when it escalated as it is our only vehicle and we are extremely busy. We hadn’t had the chance to take it in yet then in January 2024, while my wife was driving, water, literally poured into her lap while she was driving from the ceiling which could’ve caused an accident, when we took the vehicle in to get it serviced, they stated something that just sounds ridiculous. Something no one even ever made us aware of and something I’ve never in my whole history of owning vehicles with sunroof have I ever experienced I’ve never had a vehicle pour water from the ceiling , the dealership told us that it was our responsibility even though we have all warranties that you can have an as I’m looking online so many people with 2020 Buick Enclaves are having the same exact issues with the water pouring from the ceiling. We have not even had our car for three years and now our car is pouring water constantly ruining our vehicle and it is a very big safety concern. We have children and waters pouring all over the driver while they’re trying to drive. I believe this is very big safety concern. I do believe that this is some type of malfunction with the design, as I did see a recall for the same problem on a Enclave, a few years older then ours. I pay $600 a month for my vehicle and I do not have $600 to get the situation fixed when I don’t believe that I should have to pay that when my vehicle came with this issue if someone could please look into this I would greatly appreciate it and I’m sure the hundreds of other people on the Enclave recall thread as well. Not to mention the things inside of the vehicle that all this water could damage like my onstar.

We were on a trip home from the holidays about 400 miles away when we heard a huge explosion! the front sunroof exploded and rained glass all over us. It was a clear night with no other cars around. We had to pull over and find something to cover over the sunroof because it was so loud and shooting bits of glass all over us and our dog. We made it home. We are still waiting on insurance to fix it. This really scared us.

When starting our 2020 Buick Enclave I noticed the low voltage battery light stayed illuminated after startup. A message followed on the message center located in the center of the gauge cluster. The message read service electrical charging system. Followed by a message stating low voltage vehicle MA stall. This particular vehicle only has 38,000 miles on it and I have not experienced any issues with the electrical charging system prior to this incident. There have been no indication as to the battery or alternator failing (ex. Dim lights, flickering lights, malfunctioning electronics/electrical equipment, unusual noises coming from engine bay). I acknowledged the messages with the button on the steering wheel. I proceeded to drive and the low voltage light went off shortly after. I proceeded to drive approximately 75 miles without incident. Shortly before arriving at my destination the low voltage warning light illuminated and the messages appeared on the center screen on the instrument screen. I again acknowledged the messages ,but this time the low voltage light stayed illuminated until I shut the vehicle off at my destination. I visually inspected the battery post, connections, serpentine belt, and alternator. Nothing looked out of the ordinary and all connections were tight and free from corrosion. Nothing smelled burnt as it would if wiring overheated or alternator. I proceeded to start the vehicle. The vehicle started without hesitation and the low voltage light was not illuminated. I proceeded to drive to a local parts store which was a couple of miles away. On the way to the parts store the low voltage light came on and the messages appeared. I left the vehicle running at the parts store. The employee tested both alternator and battery. The alternator was showing that it was failing only producing 8. 6 volts to the battery while the vehicle was running. I proceeded to leave the store. At this point all electrical shutdown simultaneously. Vehicle to be towed.

The recall on airbags is not able to be done. I do not feel safe using my vehicle until work is done to drivers side airbag. I need a rental car to use in place of my 2015 Enclave. Help is needed with this issue immediately.

On a few occasions, while driving, the car will shut completely off. In these incidents, wrecks could have been caused. I almost ran in ditch one time and almost hit a stop sign because the steering wheel wouldn’t turn since the vehicle was cut off. The latest incident happened on 10-22-2023. On several occasions, while driving, the traction control light will come across the dashboard “traction control off”, immediately after the engine light will come and another alert come across the dashboard “reduced power. As you pull over or begin to stop, the car will shake really bad and another alert will come across the dash board saying “service stabilitrak.

A known defect that was previously addressed in a previous recall on the 2019 model year is still occurring on 2022 Buick Enclaves with no repair offered by gm. The defect causes a large hole to form in the exhaust pipe between the exhaust manifold and the muffler which could leak carbon monoxide into the passenger compartment and cause decreased engine performance. In the attached pictures the defect hole noted in the recall exactly matches the hole in the 2 pictures of the underside of my car in the exact same spot is the previous recall identified. It’s obvious that gm is still producing defective components and parts and placing them on their vehicles after a recall had caused repairs to previous model years.

Ac issue causing it hot to be in vehicle in this hot drought we are in. Ac blows hot indicating that there is a leak in the system of freon. This needs to be fixed as I was researching I found many others complaint of the same year 2013 Buick Enclave having the same issue. In the south it is too hot and not safe for anyone to be in a vehicle with out a working ac and costly to find issues to fix the entirety of the ac in a vehicle to fix. Please help!.

The hatch door slam down by its self and it hit my daughter and my husband two different times because it slam down with no warning .

I have received four recall notices (dated June 2023, 08/21/2023, 09/19/2023, and 10/17/2023) relative to the drivers air bag inflator may explode. I have reached out to the dealer to schedule the free recall repair to no avail. Each time they have informed me that parts are unavailable. It now has been several months since they have not contacted me for repair or resolution. Occasionally, the service airbag indicator light of the vehicle comes on. Meanwhile, I continue to drive this vehicle at great risk of injury and death. Request help in getting the manufacturer and dealer to expedite in fixing the problem. Thank you.

The rear liftgate locking mechanism failed to latch causing cargo to exit the vehicle where the car behind this car smashed into the cargo causing an accident. For whatever reason the rear door will not lock at all. The fuse was perfectly fine, appears the actuator is defective. No warning was given because the rear liftgate was open and unlatched. After realizing the gate would not close it would notify it was open but the power liftgate operates just fine, and when you activate it, it will push the gate closed and not give a warning until maybe you hit a bump in the road.

The recall that is out on my vehicle right now could cause death and it has not been fixed in a timing manner. It’s been nearly 3 months since the issue has come to my attention and I’m terrified to drive with my three kids wondering if my airbags deploy, how many of us could die.

This vehicles exhaust system has two brackets that broke off the exhaust due to bad welds. There is TSB out for one of the brackets where they replace one cheaper pipe but no mention of the other. This TSB is for multiple years same issue, 2019, 2020, 2021 and 2022. Yet I was told mine is not included by dealer over the phone. There are literally thousands of complaints stretched across multiple sites with the brackets breaking off and exhaust leaking into the car after. This issue is right at the back of engine. It’s leaking exhaust right into the cabin from the venting system to the point we get sick now. It’s $800 I was told to fix the 2 pipes that are faulty. Just bought this 2 years ago and have owned many gm vehicles in last 35 years not one has ever had any issue with the exhaust system. And the one pipe that broke and cost $420 for just the part is also on back order cause they have replaced way more then normal and it’s also the part that’s not under any TSB yet.

2015 Buick Enclave with 19k miles on it and the ac just broke and freon sprayed through the vents while driving. Almost caused an accident as we couldnt breathe and had to pull over.
