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 contact owns a 2018 Buick Enclave. The contact stated while driving approximately 35 MPH, and at various speeds, while the brake pedal was depressed, there was an abnormally loud high-pitched grinding or squeaking sound coming from the brakes. The contact stated that the noise was loud enough that pedestrians would turn and look at his vehicle when he depressed the brake pedal. The contact stated no warning light was illuminated. The contact had taken the vehicle to a local dealer, where the sound was being emitted and could not repair the failure. The manufacturer had been informed of the failure. The failure mileage was approximately 60,000.

WHILE DRIVING ON VERY SLICK ROADS ON A HIGHWAY, I ATTEMPTED TO BRAKE THE VEHICLE IN PREPARATION TO MAKING A LEFT HAND TURN. I COULD NOT STOP THE VEHICLE. THE WHEELS KEPT PUSHING ME FORWARD. I COULD FEEL THE ABS PULSING BUT THE VEHICLE WOULD NOT STOP. LUCKILY, NO ONE WAS AHEAD OF ME OR I WOULD HAVE HIT THE VEHICLE. IT FELT LIKE THE CAR WAS OVERRIDING MY ATTEMPTS TO STOP IT. I WASN'T JUST SLIDING ON SLICK ROADS; THE VEHICLE WAS ACTIVELY PUSHING ME FORWARD.

Dec 11, 2020

THE E-BREAK WARNING CAME ON TWICE AFTER RELEASING THE E-BREAK WHEN PARKED, THE WARNING CAME ON SHORTLY AFTER PULLING FROM A SHOPPING CENTER PARKING LOT. THE E-BREAK LIGHT WAS FLASHING WITH THE 'SERVICE LIGHT' ACTIVE AND A DISPLAY NOTIFICATION OF EMERGENCY BREAK ISSUES. BOTH OF THESE TWO INCIDENTS HAPPEN AFTER THE LAST SERVICE UPDATE N19221631 WAS IMPLEMENTED BACK ON 5/2020. THE FIRST ONE WAS PRESENT AROUND SEPTEMBER 2020 AND THE LAST ONE ON 11/23/2020. I'M NOT SURE IF THESE TWO INCIDENTS HAPPEN DUE TO THE IMPLEMENTATION OF THE SERVICE UPDATE BUT IT SEEMS COINCIDENTAL THAT THEY HAPPEN SHORTLY AFTER THE SERVICE UPDATE AS THIS CONDITION DID NOT OCCURRED BEFORE THE SERVICE UPDATE. I DO NOT DRIVE MY BUICK MUCH WITH ONLY ABOUT 11K MILES CURRENTLY SO IT IS NOT OBVIOUS THE PROBLEM IS DUE TO AGE AND USAGE UNLESS THERE IS A DEFECT WITH THE E-BREAK PRODUCT.

THE ELECTRONIC PARKING BRAKE HAS TURNED ON 5 TIMES NOW. 3 TIMES, THE CAR WAS IN PARK AND THE EMERGENCY BRAKE HAD TURNED ON AND WOULD NOT TURN OFF. THE BRAKE WAS NOT ACTIVATED BY ANYONE. THEN IT HAPPENED WHILE DRIVING. THE VEHICLE WAS TOWED TO A DEALERSHIP. THEY WORKED ON IT AND SAID IT WAS FIXED. THIS WEEK WHILE DRIVING HOME FROM THE GROCERY STORE THE BRAKE TURNED ON AGAIN. THE VEHICLE WAS AGAIN TOWED TO THE DEALERSHIP.

The torque converter is failing it seems this is far too common and dangerous with all Buick enclaves for this year. The vehicle shakes when applying the gas not having the power it needs to keep a steady speed without shaking. A mechanic stated the torque converter is bad known as the “GM shutter”

Place car in park, went into store, came back out tried to put car in reverse, car would. To go, tried it two more time, car would. To go in reverse. Turned car off, put in drive , would go in drive, put in reverse, car would go, but the engine light came on and stayed on until later that day. Took car to the dealer that Monday morning, (Onstar notification says engine or transmission problem, park brake assist light came on a few times flashing on dashboard.dealer tells me first, needs to change transmission fluid. Then told me it is the solenoid switch in the transmission. Dealer calls National auto care(my warranty) and tells them that the problem, warranty wants the cause and part#. Dealer came out to look at car, stated don’t drive because their is slim metal shavings in transmission fluid. No one can tell me where it’s coming from. And the warranty company will not replace the transmission. So here I am paying a car note and a warranty. No fix

For 6 months I have had a shutter in the front part of my car. When I accelerate the car violently shakes. The car was under bumper Bumper warranty when this problem started. I have taken it to my dealer on multiple occasions and they and their engineers cannot determine what is causing the problem. They have had several other enclaves come in with the same issues. They replaced my transmission among other things and nothing fixes it. I have contacted buick headquarters and I am only permitted to speak to customer service who only tells me the same thing that my dealership tells me. I am frustrated and don't know what to do. The problem is getting worse. The dealership says they are working with engineers and they cant seem to find the problem. I'm told my dealership has 6 other buick enclaves with the same issue and other dealerships he had some as well. There has been no warning icons show up.I have no copies of paperwork where my dealership has worked on my vehicle, but they have everything in their computer. My dealership is Bob Ross in Centerville, Ohio. I'm not sure if this is a safety issue or could become one since no one seems to know what is wrong with my vehicle.

DURING NORMAL COMMUTE, VEHICLE BEGAN BUCKING BADLY, WOULD NOT ACCELERATE AND BEGAN ROLLING BACKWARDS. CHECK ENGINE LIGHT ILLUMINATED. SHUT VEHICLE DOWN, RESTARTED, AND THE PROBLEM SEEMED TO CLEAR. BROUGHT VEHICLE TO DEALERSHIP, FOUND CODES P0011, P0014, P0021 AND P0024 SET. DEALERSHIP CONTACTED GM, WHO ACKNOWLEDGED THE ISSUE BUT OFFERED NO FIX. THEY ARE STILL STUDYING THE ISSUE AND HAVE NO RESOLUTION. DEALERSHIP CLEARED CODES AND RELEASED VEHICLE BACK TO US. ISSUE MAY RETURN AT ANY TIME. HOW CAN I TRUST MY FAMILY IN A VEHICLE THAT MAY SUDDENLY, WITHOUT WARNING, BEGIN BUCKING, STOP ACCELERATING AND CAUSE AN ACCIDENT? THIS IS AN UNSAFE CONDITION THAT GM NEEDS TO ADDRESS. I AM DISAPPOINTED THAT THEY HAVE NO RESOLUTION. DEALERSHIP REFERENCED BULLETIN PIP5569E, SO GM ACKNOWLEDGES THE ISSUE. I FOUND REFERENCES FROM ALMOST A YEAR AGO TO THIS ISSUE VIA GOOGLE - THAT'S VERY DISCONCERTING THAT, IN THIS TIME, GM CANNOT IDENTIFY A FIX.

THE "START STOP" FEATURE CAUSED A LIFE THREATENING HESITATION UPON ACCELERATION FROM A FULL STOP AT AN INTERSECTION. ENCLAVE DOES NOT OFFER ANY OVERRIDE FOR THIS OPTION. THERE MUST BE A FIRMWARE UPDATE PROVIDED BY GM TO ALLOW IT TO BE DISABLED!!! THIS IS GOING TO KILL SOMEBODY!!!

My car starting sputtering on take off from stops, extremely dangerous if you’re trying to get out in traffic and keep up quickly from a stop. Then when I took it to get looked at it the mechanic said it needs a new transmission. Now my family is stuck because that’s our only vehicle big enough for our growing family. They’re was a check engine light that keeps coming on.

The contact owns a 2018 Buick Enclave. The contact stated that while idling or at a complete stop, the vehicle lunged forward upon acceleration. The contact then stated that while shifted to park, the vehicle inadvertently started. The contact also stated that she heard a screeching sound in the wheels while shifting in the first gear, and intermittently in second and third gear. Additionally, the contact stated that the check engine warning light was previously illuminated; however, after driving the vehicle, the check engine light turned off. The vehicle was taken three times to the dealer where the failure could not be duplicated. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was informed that the warranty was not honored, and no assistance was provided. The failure mileage was 125,639.

SHORTLY AFTER GETTING GAS, THE CAR WILL REV TO 2-3RPM WHEN LIGHTLY ACCELERATING, AND SEEM TO "RUN ROUGH". THEN, AFTER COMING TO A STOP AT A TRAFFIC LIGHT, THE CAR WILL AUTO STOP AND THEN SHIFT INTO NEUTRAL. I CAN NOT SHIFT BACK INTO DRIVE WITHOUT PUSHING THE START/STOP BUTTON TO RESTART THE CAR. IT DOES NOT HAPPEN EVERY TIME I GET GAS, BUT ALL 3 TIMES IT HAS HAPPENED HAVE BEEN AFTER GETTING GAS. THE FIRST 2 TIMES IT HAPPENED, I WAS TOLD THERE WAS A RECALL, WHICH WAS THE CAUSE, BUT THIS LAST TIME, THERE WAS NO RECALL, AND THEY SAID THERE WERE NO ERROR CODES, SO THEY DO NOT KNOW WHAT IS WRONG. THE CAR STALLING EPISODES OCCURRED IN AUGUST 2019, SEPTEMBER 2019, AND FEBRUARY 2020. IT MAY OR MAY NOT BE RELATED, BUT IN OCTOBER 2019, THERE WERE ALSO 2 INSTANCES OF AN "EVAP LEAK" THAT WERE FIXED.

At least 3 or 4 times, the car has remotely started itself while the key fob is in my pocket. Two times, the car was in my closed attached garage. To remote start the car, I would have to press and release the lock button on the fob, then hold down another button for four seconds. At times while I am working around the house or garage, I hear the car beep, indicating that my movements pressed the lock button. On the times mentioned above, evidently my movements pressed the two buttons, causing the car to start. I mentioned this to the service department of our Buick dealer, Dave Cross Motors in Lee's Summit, MO. They were not too concerned, and said that the engine would shut off after 10 minutes. I feel this could be a health concern. If the car did not turn off after 10 minutes, carbon monoxide could build up in our attached garage, and injure or kill us. Also, if someone broke into the car while running like this, could they steal it without the key fob being present. I have never had problem with my 2011 Ford F150 that has it's key fob on the same key ring.

I DROVE OVER SOME METAL COVERING OF A POT HOLE OR OTHER TYPE OF HOLE ON LEXINGTON AVENUE AND ABOUT 100TH STREET IN NYC TODAY. WHEN I DROVE OVER THE METAL COVERING THE CAR STOPPED. THIS IS THE AVENIR MODEL WHICH HAS AUTO STOP. THANKFULLY, THE CAR BEHIND ME STOPPED AND DIDN'T HIT ME. I WILL TAKE THE CAR IN TO BE EXAMINED BUT I THINK IT'S A MALFUNCTION OR ISSUE WITH THE AUTO STOP. WHEN I CALLED THE DEALER, THEY SAID IT WAS NOT THE CAR'S FAULT. I WANTED TO REPORT IT IN CASE THERE ARE OTHER COMPLAINTS CONCERNING SIMILAR ISSUES. THE DEALER CLAIMS THAT THEY HAVEN'T SEEN THIS ISSUE.

PREMIUM PACKAGE COMES WITH SAFETY ALERTS. HOWEVER THREE OF THE ALERTS DO NOT PROVIDE ANY OF THE SAFETY FUNCTION DESCRIBED. FRONT COLLISION ALERT - HAVE HAD THREE EMERGENCY BRAKING SITUATIONS AND IN ALL THREE WHERE THE RED BEEPING ALERT IN THE DASH DID NOT FUNCTION. TESTED BY GM ENGINEER AND HE COULD NOT MAKE IT WORK AT OVER 20 MPH. ICONS IN INSTRUMENTION LIGHT UP SO IT IS SEEING CARS BUT NO WARNING AT STATED. FRONT PEDESTRIAN ALERT - SIMILAR TO ABOVE, CAR IS SEEING PEDESTRIAN BECAUSE ICONS LIGHT UP GREEN AND AMBER BUT FLASHING RED AND BEEPING DO NOT OCCUR WHEN YOU GET IN DANGER ZONE LANE DEPARTURE WARNING - THERE IS NOT BEEPING WHEN YOU CROSS A LANE WITHOUT USING TURN SIGNAL. LAND ADJUSTMENT WORKS SO VEHICLE IS SEEING LINES BUT IF YOU CROSS THE LINE WITHOUT ANY MANUAL EFFORT THE ALERT DOES NOT WORK A GM ENGINEER FOR THE HOUSTON AREA DROVE THE CAR AND COULD NOT GET ANY OF THESE FUNCTIONS TO WORK. HE CALLED GM AND WAS TOLD NOT TO TEST THIS THE FRONT COLLISION IN THE FIELD BUT THAT IT WAS TESTED AT FACTORY AND WORKED AS DESIGNED. SO GM SAYS THERE IS NOT ISSUE EVEN THOUGH I HAVE HAD 4 SITUATIONS WHERE IT SHOULD HAVE WORKED AND THE GM ENGINEER COULD NOT GET ANY OF THEM TO WORK AS OTHER GM CARS. OTHER ENCLAVES ON THE LOT ALL HAVE THE SAME ISSUE, SO IT IS EITHER A DESIGN FLAW OR A PROGRAMMING ISSUE, IN ANY EVENT IT IS A SAFETY FEATURE THAT IS NOT WORKING AS DESCRIBED OR AS IN OTHER GM CARS I OWN. THEY ARE NOT WILLING TO DISCUSS IT ANYMORE BECAUSE EVEN THOUGH IT DOES NOT WORK IN THE FIELD FOR HIM OR ME, THEIR ENGINEER SAID IT IS WORKING AS DESIGNED.

SEAT BELTS

1 complaint

In December 2017 we were involved in a rear end collision so violent the spare tire was knocked out from under the vehicle. Our vehicle, 2014 Buick Enclave VIN [XXX] was struck in the rear. The lap belt held us secure, but the shoulder belt allowed us to be tossed forward. My head hit the left windshield/top post leaving me looking like a racoon the next day. General Motors representatives, [XXX] CEO at the time ,stated the seat belts functioned properly. I injured my left wrist as a result of being thrown forward and have pain in it ever since then. We now drive a 2018 Buick Enclave VIN [XXX] that we purchased as a result of the December 2017 accident. We have noticed the same problem with the shoulder belts not working in sync with the lap belt, especially during a panic braking. Could this be product failure or just coincidence? I BELEIVE THIS WARRANTS EVALUATION! Thank you. My email address is [XXX] , mailing address is [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

EXTERIOR LIGHTING

1 complaint

The headlights continously and irregularly flicker between high and low beam while driving at night. I have no control over it and cannot turn off the high beams when they activate. This is highly annoying to drivers ahead me, as they believe I am trying to get their attention (or be obnoxious). In these times and the legalization of open carry weapons in the state of Florida, this can be highly dangerous if the wrong person is aggravated by unintentional signaling. I have already had issues on the road with drivers not happy with the high beam flicking on and off at them while driving on the road. They have become very aggressive, following, slowing down, honking at me because they think I am being impatient or trying to tell them someting is wrong. I spent $2000 in January 2025 trying to get this fixed and it has started (December 2025) happening again.

The contact owns a 2018 Buick Enclave. The contact stated that after picking up the vehicle from the dealer for a different failure, the exhaust pipe made an abnormally loud sound while driving. The check engine and other unknown warning lights were illuminated. The vehicle was taken back to the dealer, who determined that the catalytic converter had failed and informed the contact that the catalytic converter and the front exhaust pipe needed to be replaced. The vehicle was not repaired. The contact related the failure to Special Coverage Adjustment: N212356540 (Front Exhaust Pipe); however, the VIN was not covered. The manufacturer was made aware of the failure and advised the contact to report the failure to the NHTSA Hotline. The failure mileage was approximately 100,000.

The contact owns a 2018 Buick Enclave. The contact stated that while making a left turn, another vehicle jumped onto a curb and struck the rear end and rear tire of the vehicle. The front driver side, passenger side, and curtain air bags deployed. The contact was concerned about whether the air bags should have deployed for the type of impact experienced. No warning light illuminated. The local dealer was contacted. The vehicle was not diagnosed or repaired. A police report was filed. The contact sought medical attention for bloody stool, lower back pain, and neck pain. The manufacturer was not made aware of the failure. The failure mileage was approximately 83,000.

I am a [XXX] and owner of a 2018 Buick Enclave that suffered a catastrophic transmission failure which nearly killed me and my child. On Friday, [XXX], while driving westbound on [XXX] from Edison, NJ to my home in Easton, PA, my vehicle suddenly and without warning came to a complete halt in the fast lane. A driver tailgating me swerved at the last second to avoid impact. Moments later, when I tried to move again, the car lost all power and drifted helplessly across two lanes of speeding traffic, directly into the path of two tractor-trailers barreling down at highway speeds. This was the hottest day of the summer, and I was left in terror, fully aware that one wrong move would have ended our lives instantly. The fact that my child could have lost their only parent because of a mechanical defect is beyond unacceptable. The stress, fear, and trauma of this incident cannot be overstated—it was a near-fatal event that never should have happened. My mechanic has since confirmed the transmission is destroyed, with black metal fragments throughout—clear evidence of internal failure. Only two months earlier, in June 2024, the car passed inspection with no codes or signs of a problem. This was not wear and tear; it was a hidden, catastrophic defect. In December 2024, GM recalled more than 461,000 vehicles, including certain 2018 Enclave models, for transmission defects leading to rollaway and internal failure. Source: The Lemon Firm, 12/18/24 [XXX] ). My case mirrors the defect exactly, yet I never received recall notice. I demand GM confirm my VIN’s inclusion and cover the full cost of repair or replacement. I barely escaped a fatal crash. GM must act immediately before lives are lost.

The car shuts off at random when coming out of autostop, the car will disable power steering when coming out of autostop to make turns making it difficult to turn the steering wheel.

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.

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.

LIGHTS ON MY DASHBOARD GOING CRAZY... THE GUY WHO WAS BACKING UP AS I WAS GOING BY, HONKED AND YELLED AT ME BECAUSE HE DIDN'T KNOW WHY I WOULD STOP LIKE THAT. I SHOULD HAVE BEEN WELL PAST HIM, BUT MY CAR DECIDED WE WERE STOPPING. SO A LITTLE SHAKEN AND UPSET, BUT I CARRIED ON. THIS CAR HAS BEEN DOING THAT SINCE 4000 MILES. IT IS VERY STRESSFUL TO GET IN THAT CAR AS IT IS. I SAT AT THE VERY NEXT RED LIGHT AT THE PARKING LOT I HAD JUST LEFT TO TURN LEFT ONTO A MAJORLY BUSY STREET. THE LIGHT WAS RED, WHEN IT TURNED GREEN, I APPLIED THE GAS AFTER A AND IT SURGED SO HARD, IT WAS AS IF I FLOORED IT ALL THE WAY, BUT THE PEDAL HAD NOT MOVED UNDER MY FEET, BUT I COULD FEEL ALL KINDS OF 'ACTION' HAPPENING UNDER MY FEET. AS THE CAR WENT OVER THE CROSSWALK PAINT, IT SCREECHED THE TIRES AND I ALMOST HIT THE GUY WHO WAS ALSO MAKING A LEFT NEXT TO ME AS MY CAR WAS THRUSTING FORWARD WITH GREAT SPEED AND SPINNING TIRES, WHEN THE WHEELS CAUGHT THE PAVEMENT I ALMOST HIT THE GUY NEXT TO ME IN HIS BACK DOOR. I WAS HONKED AT AND SCARED. I WAIVED MY HANDS TO TRY TO SAY ' I DON'T KNOW!' I DIDN'T KNOW WHAT TO DO. THE MAN FOLLOWED ME ALMOST A MILE TO MY WORK AND WHEN I GOT OUT OF MY CAR HE CALLED ME EVERY NAME YOU CAN THINK OF. THIS CAR IS REALLY SCARING ME AND I CANNOT DRIVE IT ANYMORE. I AM GOING TO TRY TO WORK WITH GMC TO TAKE IT BACK. I SHOULDN'T HAVE TO BE TERRIFIED TO GO TO THE GROCERY STORE. THIS CAR HAS DONE SIMILAR THINGS OVER THE LAST TWO YEARS BUT IT HAS ONLY GOTTEN WORSE.

I WAS STOPPED AT AN INTERSECTION AT A TRAFFIC LIGHT & WHEN THE LIGHT TURNED GREEN, I TURNED LEFT & I'M UNCERTAIN IF MY EMERGENCY BRAKES KICKED ON OR IF MY CAR SIMPLY STALLED OUT, BUT MY CAR SUDDENLY WOULD NOT MOVE. MY PURSE, IN THE PASSENGER SEAT FLEW FORWARD & HIT THE FLOOR OF THE VEHICLE. THE CAR BEHIND ME AT THE LIGHT NEARLY REAR ENDED ME, BUT FORTUNATELY DID NOT. WE BROUGHT THE VEHICLE TO JIM ELLIS BUICK TO BE SERVICED, BUT THEY SAID IT APPEARED FINE & WAS CONFUSED. I DEFINITELY WAS NOT IN ANY DANGER OF HITTING ANYTHING WHEN TURNING AT THE INTERSECTION. THIS INCIDENT HAS MADE ME UNEASY WHEN OPERATING MY CAR.
