2019 BUICK ENCLAVE Recalls, Complaints & Safety

The car hesitates when accelerating. It feels like its going to die. Also, the car has shut off randomly with the display saying "not in right conditions to start". The dying has happened a few times.

What component or system failed or malfunctioned, and is it available for inspection? The issue appears to be related to the auto start-stop system and/or an EVAP-related component, as the vehicle will sometimes completely shut off instead of restarting when stopped. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? When the engine shuts off, the vehicle loses all power, including steering and brake assist. This has happened at red lights, stop signs, and in school zone traffic. I have to restart the vehicle while stopped in active traffic lanes, which puts me and others at high risk of being hit. I am a single mom with 3 young children. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. A Buick dealership inspected the vehicle earlier this year. They observed the stalling issue but could not identify a single cause. They suggested possible repair attempts, but the issue has continued. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? It has only been inspected by a Buick dealership service department. No other agencies have inspected it. Were there any warning lights, messages, or other symptoms prior to the failure? When did they first appear? No warning lights or messages appeared when it first happened. The problem began before I replaced the battery, and replacing the battery did not resolve the issue. Additional Description: When I come to a stop—at red lights, stop signs, or in traffic—the vehicle’s auto start-stop system activates like normal, but instead of restarting, the engine will completely shut off. I then lose power steering and braking support and must restart the car in the middle of the roadway. It is unpredictable and unsafe. Sometimes it’s instantly but today I sat there for 15 minutes waiting. I took it straight to autozone and everything tested good.

I purchased my vehicle in 2020. In 2022 I experienced an issue where my car stopped in the middle of the road without warning. Despite several attempts to try and move the vehicle off of the road the police were notified and my vehicle was towed. The vehicle gave an error code that conditions not met for driving. One office tried to put the vehicle in neutral but the wheels locked and the shifter was locked as well. The battery has been replaced 3 different times since I have owned the vehicle. A mechanic friend of mine (who is a trainer for GMC) hooked his computer up to it and found no issues. He did find a loose wire which he the reconnected. I was able to drive my car for 6 months before the same thing happened, same situation the vehicle just stopped in the middle of the road only this time I couldn't turn the vehicle off, we had to manually disconnect the battery and again the police came out due to traffic hold up. My car was towed twice afterwards as I could get the car running for a few minutes before another error. To date my car has been sitting in my driveway since March of this year, this time it won't hold a charge and will not even start. Im not sure if this is an engine or an electrical issue. I did call 2 Buick dealerships that told me that it would take about 5 hours to diagnose the issue where I would be charged per hour at the mechanic hourly rate. At this point I think my vehicle needs to be recalled, even if I could get it repaired I dont feel safe driving it. Thankfully it stopped on a minor freeway and no major incidents occurred.

This is the third time in less the last couple of months that the air conditioning system on this 2019 Buick Enclave has failed. The vehicle consistently blows only hot air, regardless of whether it is in motion or stationary. The problem does not fluctuate with changes in speed or drive duration. In addition, there is a consistent noise coming from the dashboard area that resembles a hydraulic hinge or actuator.

The 2019 Buick Enclave was taken in for transmission fluid flush & check. The dealer came back and stated that the torque converter needed replacement. The car was still under mileage warranty but just past the roll-off-line date by a month. There are numerous issues all over the internet related to The Enclave torque converter issues. Even a service bulleting PIP5608J that covers these exact issues. It is a wide spread safety issue. If the transmission fails, what is the outcome at high speeds? It has just over 69,000 miles. Todays transmissions should last 150,000 miles minimum. Unacceptable!

The contact owns a 2019 Buick Enclave. The contact stated that while at a stop light the Auto START/STOP feature malfunctioned. The contact stated that after releasing the brake pedal, the vehicle turned off instead of restarting the engine. The contact stated that several minutes had passed before being able to restart the vehicle. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure, but no assistance was offered. The contact was informed that the VIN was not included in NHTSA Campaign Number: 20V668000 (POWER TRAIN). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 60,000.

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.

Start/stop function malfunctioned in the middle of the road, this has happened multiple times before and after replacing starter and battery, looked at by several mechanics. If I stop the car at a light or in traffic my car will dint turn back on or let me shift. Thus a safety issue because I could have been hit as it stopped in a busy road and people had to move around my vehicle. Engine light came on after failure and ceased the engine and i couldn’t move to the intersection. I also just got an oil change. They first appeared a few months ago and I had already gotten work done on it and it keeps happening

One day, I looked over at my seat and there were literally two tears in the leather. I immediately looked to see if something had ripped them. The only thing I put over there is a small cloth lunch sack so there’s no way that that could’ve done it. there was NOTHING SHARP on the seat. I am also very good about keeping my leather maintained and car maintained . It needs to be repaired before it gets worse.

On Sept 6th the check engine light came on. A diagnostic test showed it was code P0442 related to the canister purge valve /solenoid. It also showed that it was a permanent thing that had been on there a while but when I look up my Vin number there is no recalls for it, but there is for other 2019 Buick enclaves.

I found where there was a recall on 2019 Buick and mine was not listed. It is doing what I have read about the recall. The transmission is shuttering at low speeds.

The cooling fan motor assembly is shorting out internally & blowing the 70 amp fuse dedicated to that circuit. Mustreplace fan assembly and fuse to correct this concern

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.

The contact owns a 2019 Buick Enclave. The contact stated that upon the start of the vehicle, a loud grinding noise would emit from the rear end of the vehicle. To correct the failure, the contact operated the vehicle in front-wheel drive instead of all-wheel drive. The vehicle was taken to a dealer for service, but the contact was given a diagnostic fee and declined. Upon investigation, the contact discovered that the cause of the failure was linked to the rear differential. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 87,000.

The contact owns a 2019 Buick Enclave. The contact stated while attempting to buckle the seat belt however, the seat belt failed to lock securely in the buckle. The contact inspected the buckle and became aware that an internal part of the buckle had detached, preventing the seat belt from being latched securely. The contact called the dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 43,000.

There are a couple of issues causing our concerns about the car. 1. Alternator - The alternator was reported went bad after only 4 years of usage, the dealer refused to pay the fixing cost for this. Due to the failure of the alternator, the car lost all the power in the middle of the road with our entire family in the car during the night, very dangerous. The car suddenly stopped at the road with 50MPH speed limit. 2. Engine and Catalytic converter pipe - The engine light is on due to abnormal feeling of the engine power, the dealer could not fix the issue in weeks and no rental car provided and we were asked to drive the car home and waiting for order status of the parts. 3. Exhaust system failure - The dealer mentioned the welding of the connection is bad ( still under warranty ) but refused to fix it but ask the customer to pay for the replacement and labor.

Traveled and car begin to shake when I got to destination. The shift gears lights started going from neutral to Low gear and my speed began to drop down even when I was accelerating. The engine light came on and the stabilitrak light was on during times I stop at lights or stop lights only when in traffic but not on the highway. After seen by an auto service dealer, the stabilitrak light still comes on during stops at the light or stop signs and hesitation to accelerate with a heaviness to steer. There appears to be a dragging or pull when accelerating not very smooth. The service was with the transmission, however, no attempt to fix the stabilitrak and now I am to take it back in, not really enjoying my vehicle, my American vehicle, this really saddens me.

The passenger side seat air bag exploded and burned my daughter’s back while she was getting into the car. The car was in park and auto started. My son was sitting in the back seat behind her while this happened. She has 1st and 2nd degree burns and thankfully my son is okay. The car has been sitting in my driveway since that day. I have contacted the dealership and GM as well as my personal insurance. GM is moving very slow and stated they would send someone to look at my vehicle within 7-10 days from yesterday . The investigation could take 30-60 days before we have an answer. We are currently on day 11 since this happened. Insurance doesn’t want to touch it until GM or the dealership looks at it and determines if it is a malfunction. The safety of my kids and family is definitely a priority and the fact that this happened is scary. The loudness of the explosion was like a gunshot inside the vehicle and the fire that came out of it is insane. Literally looked like a firework. With the airbag deployed I am sure the seatbelts are now compromised but either way I will not risk my life or anyone else’s and step foot in it. The car was looked at by local law enforcement and pictures were taken. The car is available for inspection but the dealership hasn’t called me back and GM is following their protocol and has no hurry. The airbag light had come on the week prior to this happening and had gone back off. I also had the tire pressure lights go on and back off twice in the past couple of months.

Evaporative emission canister purge, solenoid valve, yes. My safety was at risk due to stalling 3 different times on busy roads/intersections after refueling my vehicle. When the Solenoid valve and canister fail when coming to a stop after refueling it causes the car/engine to flutter and completely stall then goes into neutral. It takes multiple restarts in order to even make the car go along with pressing on the gas. This part has been replaced twice by the dealership once at the end of march and again on the 10th of June. The first incident occurred mid-march, the second end of march and the latest incident occurred 7 June where I had to restart it 7 times before it would even drive, at that time my check engine light was on and it was making a loud noise. After this last replacement the vehicle was refueled and it started to flutter and idled hard, it will be taken to the dealership once again on the 20th of June. The vehicle has not been inspected by anyone other than dealership. There were no warning lights prior to the failure, the only indication was the car started to flutter prior to stalling. The most recent date is stated below.

On the morning of October 25, 2021 at approximately 7:05 am, I was fixing to leave to go to work. The carport light was on, so I open the door to my car, slid into the driver’s seat, started the car up and the lights came on. As I was starting to get out of the car to go turn the carport lights off, I realized the car was going backwards. I tried to get back into the driver’s seat to try to stop the car but I was unable to do so. The door knocked me down on the concrete floor of the carport and the front left tire ran over both my legs. The car continued to go backwards, the door hit the column between the carport bays but continued to travel backwards down our approx. 11-foot paved drive way, crossed the dirt road and stopped when the back of the car went into the deep ditch that runs along the dirt road at that point. When my husband arrived, the car was still running and the lights were on. The man driving the wrecker for the local EMA Director and my husband all looked at the gear shift and the car was in PARK.

Waited for train to pass and gate to raise at railroad crossing, then started to cross tracks. The car went halfway across the tracks, then the forward collision warning and automatic emergency braking activated, stopping us on the tracks. Tried again to move forward, but the collision alert and auto braking immediately activated for a second time, bringing us to a stop again. Finally was able to very slowly make my way through the crossing. I was on the tracks for 30-60 seconds. No train was approaching and it was only my wife and me in the car, but if I'd had six passengers with me and another train had approached, I am not sure I would have been able to get everyone out of the car in time. Note that there were no obstacles in front of the vehicle, but the sun was at a low angle from the front of the car and the sunlight was dappled through the treetops on the other side of the crossing (there's a left-hand curve after the crossing), creating a "moving" glare through the windshield.

Rear door with the automatic open/close feature. While accessing the rear portion of the vehicle (looking in boxes, accessing under floor storage compartment,etc) I have experienced on several occasions where the door starts to close. I was able to turn around, push the door upwards and the door stopped closing and reversed to the open area. This happened to our Buick Enclave that we own in Canada. The dealer was able to find on Buick's database where this was documented and the suggested solution was to "turn this feature off using the "control knob located in the driver's door". My wife and I are 80 and this feature was one of the reasons that we purchased this model new in May 2020. So solution that Buick has offered is not the greatest. However, my wife is disabled and if the rear door had started to close on her, I do not think that she could have stopped the door from coming down. I will be notifying the Canadian highway vehicle association of this problem. But seems to me that Buick has a problem with the design of this system and is not addressing it. Are you aware of this problem with Buick Enclaves 2018 -2021 in the USA? [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

The contact owns a 2019 Buick Enclave. The contact stated while driving downhill, he shifted to a lower gear and was depressing on the brake pedal however, the vehicle inadvertently accelerated. The contact also stated that the RPM was very high. The contact stated no warning light was illuminated. The contact stated he continued driving but had to stop 5 times to allow the vehicle to cool down. The contact took the vehicle to the local dealer. The mechanic found no failure with the vehicle. The contact stated that the failure persisted. The manufacturer had not been informed of the failure. The failure mileage was approximately 30,000. Contact was on top of Pikes Peak in Colorado. The fast idle has the engine revved to high so that when foot was off the brake on a 5-8% slope the car accelerates to 6500RPM with in 250 feet taking the car to 30MPH in low gear. Consumer had to push on the brakes constantly, all the way down the mountain which caused the brakes to severely overheat. Park ranger measured the temperature of the brakes at 375 degrees F it was after consumer had stopped to allow them to cool 3 times in about 4 miles. The car will idle at 950RPM stopped and will lurch forward when foot was off the brake. Driving on the highway speeds its fine but not on switchback mountain roads.

MY HUSBAND HAD THE KEY IN HIS POCKET UPSTAIRS IN OUR HOUSE. IT ACCIDENTALLY ACTIVATED AT SOME POINT BY HIS BENDING /SITTING. THE CAR REMOTELY STARTED AND WE DID NOT HEAR IT. ONLY BECAUSE OUR PETS BECAME UPSET DID WE DISCOVER THE RUNNING CAR IN OUR CLOSED GARAGE. WE WERE ABLE TO TURN IT OFF AND VENT THE GARAGE OF CO ACCUMULATION.

THE SEAL AROUND THE TIMING CHAIN WAS LEAKING RIGHT FROM THE FIRST DAY WE BOUGHT THE CAR. THE CAMSHAFT WAS ALSO PITTED AND REPLACED. IT WAS FIXED BY THE DEALER UNDER WARRANTY. THIS ALSO HAPPENED ON OUR 2009 BUICK ENCLAVE. IT LEAKED A LARGE AMOUNT OF OIL THAT COULD HAVE CAUSED MAJOR ENGINE DAMAGE.

SO I GARAGE MY VEHICLES I NOTICED A OIL LEAK ON THE GARAGE I DIDN'T WANT TO THINK IT WAS FROM THIS CAR SO I WATCHED IT SEEMED TO BE INTERMEDIATE AT TIMES BUT RECENTLY GOT WORSE SO I TOOK IT IN TOLD THEM AND THEY SAID IT WAS A BAD OIL FILTER BUT THE OIL FILTER IS OPPOSITE SIDE OF THE CAR FROM WHERE THIS LEAK IS DRIPPING ON MY DRIVER'S SIDE. SO I JUST WENT UNDER THERE TO SEE WHAT I COULD FIND I TOO WAS A MECHANIC IN THE ARMY AND OUTSIDE AS A CIVILIAN AFTER SO I LOOKED TOOK ME 5 SECONDS TO LOCATE IT THAT IS THE PICTURE OF THE LEAK. THEN I NOTICED RUST CRACKS ON MY FRAME SO I LOOKED MORE AND DISCOVERED THE RUST CRACKS ARE ON THE BOTTOM AND TOPSIDE OF THE FRAME. SO I DID SOME RESEARCH AND SAW COMING UP IN DEC A RECALL IS GOING TO HAPPEN FOR CRACKED FRAMES ON THE BUICK ENCLAVE 2020 BUT STARTING FROM BUILD DATE'S 3 MONTHS AFTER MINE WAS BUILT BUT MINE SHOWS ALL THE SYSTEMS OF THAT RECALL BUT ISN'T INCLUDED.
