The contact owns a 2020 Buick Enclave. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The vehicle lost motive power and was coasted to the shoulder of the roadway. No warning light was illuminated. The vehicle was towed to the dealer where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was in the process of being repaired. The manufacturer was made aware of the failure, and a case was filed. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 45,684.

Why enclave Burns about 1 to 2 quarts of oil in between oil changes so I'm constantly having to check the oil level and put more oil in it which come really close to being out of oil and causing the engine to seize Buick says this is normal and I don't think it is I have never had a car that uses oil like this new or used in addition to that the transmission is locked up twice since we have owned it and can't get it out of park can't drive it can't use it. Had to have it towed . The first time that the transmission gave issues it didn't lock up in park it locked up in drive and we couldn't put it in park I was able to get it to the dealer to get worked on it was still under warranty at that time the second time it wouldn't go out of park and could not move it it was stuck wherever we happen to be at and it would not move when they loaded it on the tow truck to tow it down to the dealer the wheels were locked up cuz it was in park and we couldn't it had to just be drug onto the truck.

The contact owns a 2020 Buick Enclave. The vehicle was reversed out of the driveway; however, after shifting into drive(D) and depressing the accelerator pedal, the vehicle jerked, vibrated, and the check engine warning light and other unknown warning lights illuminated. After several minutes, the vehicle functioned as intended. A short distance later, the failure reoccurred. The vehicle was taken to Auto Zone, but no cause for the failure was found. The vehicle was taken to a private dealer where it was diagnosed and determined that the catalytic converter was clogged, and that the electronic brake control center module and the transmission module had failed. The vehicle was not repaired. The contact stated that the failure persisted. The manufacturer was not made aware of the failure. The failure mileage was unknown.

After waiting at stop light with foot on the brake (auto stop not engaged) the light turned green. After releasing brake pedal and the car rolling approx 1 foot , then starting to accelerate, within 1-1/2 seconds the transmission went into park abruptly. The shift lever displayed “Park” and “Parking brake” on the DIC illuminated. This almost caused a rear end accident as it was so abrupt. If it would have happened at over 5 MPH the airbags could have gone off causing occupant(s) injury. The resolve was to apply the brake and shift into drive with no issue after that. Will contact dealer tomorrow.

BOUGHT BRAND NEW 2020 BUICK ENCLAVE, WITH 4 MILES ON IT, ON 6/13/20. STARTED HAVING TRANSMISSION PROBLEMS ALMOST IMMEDIATELY. THE CAR WOULD JERK HARD (HARD SHIFT) WHEN PUSHING ON THE GAS AND ALSO ANYTIME IT WAS PLACED IN PARK. ON 6/21/20 THE CHECK ENGINE LIGHT CAME ON AND THE VEHICLE WOULD BARELY SHIFT. CALLED LOCAL BUICK - GM DEALERSHIP TO GET REPAIRED. LOCAL SHOP RESTARTED COMPUTER ON 6/24/20 AND SAID THAT IT WAS GOOD TO GO. DROVE IT LESS THAN 3 MILES BEFORE SERVICE ENGINE LIGHT CAME BACK ON AND JOLTING STARTED AGAIN. ON THE DRIVE BACK TO THE DEALERSHIP THE VEHICLE CAME TO A HARD JOLTING ABRUPT STOP ON THE ROAD. VEHICLE WOULD NO LONGER START OR SHIFT. HAD TO LEAVE VEHICLE IN THE MIDDLE OF THE ROAD UNTIL DEALERSHIP COULD COME GET IT. ON 6/26/20 DEALERSHIP CALLED TO SAY THAT THE VEHICLE WAS RUNNING GOOD AND READY TO PICK UP. ON 6/27/20 DROVE CAR ABOUT 15 MINUTES BEFORE THE HARD SHIFT STARTED HAPPENING AGAIN AND THE CHECK ENGINE LIGHT CAME BACK ON. WHEN ATTEMPTING TO SHIFT INTO REVERSE, THE VEHICLE HARD JOLTED US BACKWARDS AND THEN DIED. THE VEHICLE WOULD NO LONGER START OR SHIFT GEARS. ON 6/28/20 GOT THE VEHICLE TO START SO DROVE THE VEHICLE, AS IT WAS STILL HARD SHIFTING, BACK TO THE DEALERSHIP AND DROPPED IT OFF. THE DEALERSHIP STILL HAS IT AS OF TODAY AND HAS REFUSED TO GIVE US ANY PAPERWORK FROM OUR PREVIOUS 2 ATTEMPTS AT GETTING IT FIXED HOWEVER GAVE US FALSIFIED DOCUMENTATION STATING THAT WE ONLY BROUGHT IT IN THE SHOP 1 TIME, WHEN IT ACTUALLY IS THE 3RD TIME TO BE TAKEN IN FOR THE SAME PROBLEM TO BE FIXED. GM HAS REFUSED TO REPLACE THIS DEFECTIVE VEHICLE NOR RETURN OUR MONEY PAID FOR IT.

I BOUGHT A 2020 BUICK ENCLAVE, (OWNED BY GMC) WITH 6 MILES ON IT, 1 WEEK AGO. YESTERDAY THE CHECK ENGINE LIGHT CAME ON AND THE CAR STARTED JERKING ANYTIME THE TRANSMISSION SWITCHED GEARS. I CALLED TO TRY TO GET IT IN TO A CERTIFIED BUICK DEALERSHIP TO BE LOOKED AT AND NOWHERE CAN GET IT IN FOR 3-5 DAYS AND NONE OF THE DEALERSHIPS WILL GIVE A LOANER CAR UNTIL THE TIME OF THE VEHICLE APPOINTMENT. I CONTACTED BUICK DIRECTLY REGARDING THIS AND THEY TOLD ME THE SAME THING, THAT WE CAN'T GET A SAFE DRIVING VEHICLE, UNTIL THE ONE WE HAVE CAN BE LOOKED AT BY A DEALERSHIP AND IF WE TAKE IT TO AN UN-CERTIFIED SHOP THAT IT WOULD NOT BE COVERED. SO NOW I AM STUCK WITH EITHER DRIVING AN UNSAFE CAR 50 MILES ON THE HIGHWAY TO WORK FOR THE NEXT FEW DAYS OR NOT BEING ABLE TO GO TO WORK. THIS IS A BRAND NEW CAR DRIVEN STRAIGHT OUT OF THE FLOOR ROOM! BUICK IS PUTTING PEOPLE'S LIFE AT RISK BY INSISTING THAT WE DRIVE THIS UNSAFE VEHICLE ON THE HIGHWAY UNTIL WE CAN GET IT LOOKED AT! LOOKS LIKE A HUGE LAWSUIT IN THE MAKING!!!!! *TR
