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. Coming out of autostop is typically when you are trying to go or make a turn. This has been an ongoing issue that happens often. The issues began around 60k miles.

Passenger side rear electronic parking brake wire clip failed, wire is rubbing against the rear cv boot. This caused a short that led to defective ABS control module that had to be replaced for anti-skid and anti-roll for this SUV. It also affected the transmission alert system.

-A few weeks prior to accident, while driving down a 65mph highway in TX, vehicle side mirrors were folding inward. Continued to fold inward after hit button to open them multiple times. Even did this after pulled off highway and stopped/started vehicle and exiting vehicle and locking to try to create a "reset" of system. (Auto folding windows feature in infotainment was NOT selected to be ON before or after this incident! Auto-folding sidemirrors are tied to the electron shifter status and should only engage when turned ON in infotainment option AND vehicle in PARK. This was occurring over 2-3 days while driving on highway at 65mph) Accident: -Pulled into parking spot and placed vehicle in PARK. -Front Dash Camera audio indicates the "Ding" confirmation of park and hear vehicle doors unlock upon Park status. -Vehicle was still ON and began to slow roll UP HILL BACKWARDS in parking lot and strike another parked vehicle across the double wide aisle. -No rear camera was engaged. -No collision alert (no seat vibration which was always ON in infotaiment option) -No automatic braking for about to strike a vehicle. -Display after impact was on the Buick Startup Icon, NOT the infotainment icons. -Vehicle driven immediately to Buick dealership and Claim initiated wth ESIS (regarding product liability claim with GM (General Motors) -no police due to private lot - 9 days later the black box data (Bosch Crash Data Report) and vehicle Global Diagnostics Sysem Reports were downloaded from Vehicle. Third report polling all the vehicle drive cycles was downloaded but not provided to me as consumer with claim. - No data obtained from CDR as not over 8mph and was backwards. -GDS2 indicates not DTC data most items but did indicate: 1)Rear Differential Clutch Control Module No Communication 2)Left Front Short Range Radar Sensor Module No Communication 3)Right Front Short Range Radar Sensor Module No Communication 4)Rear Short Range Radar Sensor Module No Communication

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.

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.
