1st incident I was backing out of a parking spot and it went into emergency park I had to turn off the truck , turn it back on and take it out of emergency parking 2nd incident a week later I was at a stop light the truck did the automatic shut off. When you have your foot on a break , I'll let go of the break to go through the light and it went into emergency park again engine light is on auto zone says it one of 2 different catalytic converters unsure which one would have to get them both replaced over 500 each 3rd incident auto shutdown when stopped burnt out the starter no way to turn off the auto start stop 4th incident today pulling into the parking lot at the grocery store. Doing about 10 to 15 mph truck just shut off it putting it's into emergency park or shutting of while driving is a safety issue but no recalls single mother can't afford to even have it looked at right now.

This happens every single day, not just today, but are two separate issues related to my brakes. 1- squealing brakes. Every single day and for several miles before they warm up. The first time I brought this issue to the attention of the dealership, they replaced the brakes, and there was no squealing for just a few days. I forced the dealership within a week to let them know, I had to bring it back in, and they said they were fine and would just squeal. To this day, I have no idea if this is safe or not, but haven’t been able to receive a message that they squeal for any specified reason, which does not ease safety concerns. 2- my app told me that I had only 18% brake pad life remaining when I was around 11k miles. I took it in and they said they just reset the sensor without fixing the brakes because they didn’t know why it was doing that - its now clear to me that this isn’t an accurate reflection of true brake life measurements and is most likely just based off of miles driven instead of a true measurement, as advertised. I love this car, but am super disappointed that my brakes are so consistently loud - it’s both embarrassing and worrisome. And to make the dealership aware and just have them reset a sensor for this completely separate concern is honestly obnoxious.

Driving down the street after a short trip this morning with no one on the road in front of us the vehicle had an alert like we were about to impact someone and braked pretty hard 2x back to back with the collision alert popping up. The person behind us had to slam on their brakes and barely avoid hitting us. There was nothing in front of us. This vehicle is dangerous to everyone around us and should be taken off the road.

Completely lost all power brakes while on the road today. Owned it for about 11 months. Looking like the master cylinder. We've been having random electrical issues when we're cranking it up. Weird sound coming from the dash when the ac is on on occasion. Like the car wasn't fully kicking over even though the engine was running. Sometimes turning it off and turning it back on would make it work.

Several times I have been stopped at a red light, and my parking break will come on without me engaging it. I was almost hit by other vehicles the last time my vehicle did this. People were blasting their horns and speeding around me because I was unable to move my vehicle. Because I had not manually engaged my parking break, my vehicle would not allow me to disengage the parking break until after it finally read that I engaged it. It took me 10 minutes of having to turn my car off and back on and trying to engage the parking break manually before the vehicle finally noticed it was engaged and would allow me to disengage my vehicle so that I could move it out of the way. This has now happened 3 separate times in the last month. It is an extremely dangerous situation and is making me become nervous to drive my own vehicle.

The brakes make a squealing noise when backing up and this has been reported on many 2025 Enclaves. There is also a repeated clicking noise after turning the vehicle off.

I wanted to update a previous report. The vehicle had had some odd electrical issues. The brakes ended up failing while driving but no electrical issues at the time proceeding it. What I wasn't able to report before was that the brake pedal sunk to the floor with no effort to stop the vehicle at all. The emergency brake is a button on the left side of the vehicle which was attempted to be engaged to stop. It made no effort to stop whatsoever. The vehicle is a danger to society. I just got it back from the dealership and they made an update to the computer or console but replaced no parts. These all need to be recalled no one should be driving these.

Brake booster has gone out at 100,000 miles. Brakes do not work when vehicle is first started. Problem was diagnosed by an independent mechanics shop. There was no warning light until after the first incident.

Brake pedal went to the floor 1 time when starting vehicle at approximately 400 miles.

Brakes squeak very loudly. This has been an issue since I purchased this new vehicle.

The contact owns a 2025 Buick Enclave. The contact stated that upon starting the vehicle, several unknown warning lights illuminated. The vehicle was taken to the dealer, who determined that a software update was required. The vehicle was repaired, but the failure reoccurred. The vehicle was taken back to the dealer, who diagnosed a failure with the brake master cylinder. The vehicle was not repaired due to parts being on backorder. After investigating the failure, the contact related the failure to service update: n242482170. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was 650.

In driver info center messages displayed are esc “this is anti lock cracking system not working”. Steering assist reduced “this is lane departure steering assist not working” parking brake. “not working” also cruise control is not working Buick service tells me this has happened often enough in other vehicles that there is a repair bulletin on it. Also the initial cost to repair is $3000 + if this bulletin repair fixes the problem if not there would be more costs. This vehicle is within the 36 month bumper to bumper warranty period but has recently exceeded the 36000 mile warranty threshold. I have already paid for the initial part so it could be ordered.

Brakes are extremely noisy at low speeds. Dealer advice that this is normal when driving at low speeds brakes squeak extremely loud this is clearly a defect that gm needs to address they keep using the excuse that is the the high quality pads that they are using.

We bought this 2020 Buick Enclave from pinegar Chevrolet in republic, mo from the preowned side of the dealership. When we test drove it only in the parking lot it didn't make any noises, but as soon as we drove off the lot after purchase the brakes made a noise as if the anti lock brake system was not working properly making it difficult to stop as the car should. We also was told that since this is a preowned and not a certified preowned that it was sold as is no warranty. I believe gm needs to fix this issue ASAP or the dealership needs to either buy the car back or put us into something with a warranty that doesn't have safety issues. We bought this as our family vehicle and I don't believe it is road worthy or safe to be transporting my family in.

Car was purchased on 1/2/25 and first issue with vehicle was on 1/30/25 for check engine light. Feb 20,2025-check engine light, car shakes, radio and dash go in and out, passenger rear window screeches. Issues fixed except vibration. May 26, 2025 check engine light. Rear window still making noise-fixed . Trunk gets stuck-no fix. Unaligned lane assist, car continues to shake. Sept, 26 2025-brakes continue to make noise and now pulsate. Dealer found that pads and rotors were warped and had discoloration, and were replaced under warranty at 11,845 miles. Car was in service from sept 26-oct 23, 2025. Brake noise started 2 days later-texted advisor Dec 4-car continues to shake and brakes continue to make squealing noise. Have email from gm tac stating "some noise from the brakes is a normal characteristic, especially if the brakes are cold or wet. This is a condition we have no control over as it has to deal with the environment and weather. I live in florida! car was in serivce Dec 4-Dec 26, 2025. No resolution again Feb 6-car leaking and overheating, passenger rear window not going down, exterior antenna cover came off, still shaking and brakes still squeaking. I was told brakes are no longer under warranty and nothing the can do after 7,500 miles yet they were previously replaced at 11k miles and I've voice concern for months and nothing was done before. And others were replaced even over 7,50miles I am concerned over the safety of myself and my family with these continues brake issues.

The brake system abs module/sensor malfunctions- yes it is available for further inspection. Safety is an issue due to the abs indicator light on. Yes, the problem/issue has been confirmed by a dealership. No inspections have occurred other than the dealership. The only warning is the light indicator for the brakes, parking abs.

Shortly after purchasing my 2017 Enclave premium around 60000 I noticed a problem that felt like vehicle's tires were skipping when making sharp turns. Upon my own extensive research (as I didn’t have time money and couldn’t go won’t vehicle) discovered a clutch pack needed replaced. This is after replacing the battery and brakes nit even a month after buying. Later after taking it for an oil change I received a report stating the rear differential was cracked and power steering rack needed replaced. While driving in rush hour traffic one day all power steering was lost with no explanation. Still having problems with tire pressure monitor replacing multiple tire stems and tires. Won’t start after filling with gas or is stuck in crank position trying to start when it finally dies it wants to stall out. Currently headlights are flickering with no known cause. Oh and the driver heated seat stopped working right after purchase. I’m at a huge loss with repairs costing more than the worth of a vehicle that continues to have serious issues even after fixing the problem it seems to repeat itself. Owe too much to trade in. All these problems are known to occur I cannot believe this isn’t a lemon or recalled parts. If not in Enclave same thing happens in similar vehicles made by sane manufacturers during the same years. I will never purchase another GMC nor purchase from Toyota who failed to help after purchase.

Was driving at 35 mph with no other cars or obstructions in front of me and the vehicle suddenly slammed on the brakes on its own and the throttle became inactive (would not respond to inputs). I don't know if the vehicle slammed on the parking brake or the service brakes. After 30 or so seconds everything returned to normal. No lights are illuminated on the dash, but a light did come on when the vehicle braked on its own. The light turned off before I could see what it was.

After programming we also performed the module configuration procedure and although e removed the programming error, the system is still reporting a failure with the left parking brake circuit. All circuits have been checked. The current hypothesis is that the electronic brake control module (ebcm) has failed internally.

Brakes are not stopping in time they are continuously scrubbing I have changed brakes and rotors and they are continuously scrubbing and not allowing me to stop in time nearly almost ran off the road I have got my brakes inspected but mechanic say there was nothing wrong the place I took it to but there is something wrong with the brakes. There is a electrical problem when it rains things stopped working inside the car every time it rains like my speakers my warning sensors things in that sort. There's also an acceleration issue it is not catching speed it's been doing this since I got the car how to basically mash it to the floor just for the vehicle to go.

As my husband was backing out of the garage to the east and turning the back end to the north so we could head forward out of our drive which is on a curve, the car accelerated and the brakes would not work. We went backwards down a very steep drive that goes to our machine shed and towards the bottom we were stopped by a tree. We could have suffered head trauma from the abrupt stop. If we had been backing out of the drive or a parking place, since we couldn’t stop, there could have been others involved and severe injuries. I called the sheriff’s office and they filed a report. Our insurance agent came out and took pictures. I called general motors Buick and they opened a case. The car was towed to the body shop the dealership we bought it from uses. We noticed no warning lights or messages on the dash. After everyone left, I got on my computer and there were 2 diagnostic warning emails. One for the antilock brakes and the other for the stabilitrac control systems,.

I have a 2022 Buick Enclave avenir. I purchased the car Dec 2021. I received a low pressure indicator October 26, 2022 in which I had the tire repaired. The brakes started grinding in December of 2022. I took it to the local dealership several times and have called to report the issue as well. On one visit the brake pads were repaired because of a bulletin received from gm. A few days after the replacement, the brakes are still grinding. (see attached documents) I called the dealership again and was told, I assure you that you are not the only one. There are at least 4-5 other customers in my area having the same issue and there is nothing the dealership can do until they receive instructions from gm. What can be done about this? I am concerned with this issue and would like to see it resolved or get a replacement. I have not received a follow up call regarding this issue from the local dealership or gm. My family is important to me and I am not comfortable continuing to own this vehicle without a resolve.

While driving at highway speed, service traction control/stabilitrak warning comes on. Vehicle slows and if driver attempts to accelerate (using accelerator pedal), it causes severe lurching of vehicle. This makes the vehicle basically undrivable while in the middle of traffic. You must use emergency measures to pull over (potentially across multiple lanes) off the road and while trying to do that, you are in a very high risk state of being hit. The problem is reproduceable. The manufacturer and dealer service centers are aware of this problem and it has been reported by many owners of gm vehicles since at least 2010. Search the internet and you will find hundreds of incidents being reported.

My 2022 Buick Enclave was involved in a minor accident that was a stop and go traffic . The car is supposed to have anti collision sensors in the front grill but the car did not stop or slow down and no warning lights went off , also from the hood had a buckled bacl along with the front fenders and pushed both fenders back a little enough to prevent either front door from opening had to exit through the back seat if the car had caught on fire a person would have not survived , all parts in accident where replaced by the body shop and Buick dealer had to recalibrate the collision equipment thanks for any help jeff quicksell.

The electronic parking brake has had multiple apparent malfunctions and one complete failure. On several occasions the parking brake failed to disengage completely with multiple warning dash lights illuminating. One such incident apparently self-corrected after being left parked overnight our semi-heated garage, with another incident only partially disengaged the parking brake with warning lights indicating a parking brake malfunction, and after driving two to three miles returning home the right rear brake was baking hot. The latest malfunction was a complete failure of the parking brake to engage at all, with the warning lights again illuminating and would be an obvious danger while parking. The vehicle is just over four years old and was two-and-a-half months out of warranty at the time of failure, and had/has 5,121 miles. It has now been waiting at the dealership for repairs for four weeks, awaiting a parking brake control module which they cannot give any timeline for delivery or arrival. It is unknown if the brake control module for the parking brake has any control or effect on the service brakes, so the vehicle is sitting at the dealership collecting dust, unusable to us.

The car has an auto-stop feature however at times, when the car is stopped, the entire electrical and engine shuts down even while the car is in drive. The driver must restart the car and put the car into park and then back into drive. When the car restarts, several lights/messages turn on including "service transmission" and the "service parking brake" message and parking break light. This is a safety and hazard issue as it has happened while in traffic on the freeway when at a standstill.

Brakes started grinding at 1000 miles. I will filed a complaint with the dealership and hope they record it. Now I have approximately 2100 miles on the car and it continues to sound and feel like my brake pad and rotor on the right front are grinding every time I apply the brakes. On July 23 2021 an own coming 18 wheeler did not see me and made a left turn in front of me at the traffic light . I step on the brakes lightly to stop but the car made the metal to metal sound and kept moving forward. So I had to jam on the brakes to stop. All wheels slid forward immediately except the front right. I think different brake pads and rotors are needed on this vehicle. This is definitely a safety issue to all drivers as well as others that are on the road.

While on free way transmission stopped functioning properly after exit unable to move vehicles in gear. Dealer said it was a computer programming issue. Another instance 9 months later care emergency break would not dis engage even after shutting vehicle off and restarting several times that transmission would stop shifting soon received messages dealer said it was a computer programming error .
