2018 BUICK ENCLAVE Power Train Problems

The contact owns a 2018 Buick Enclave. The contact stated while stopped at a gas station; after refueling the vehicle, the vehicle was restarted but was unable to shift to drive(D). The contact attempted to shift to reverse(R) and the shift lever failed to respond. The contact stated an unknown warning light was illuminated. The vehicle was towed to a local dealer where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 71,000.

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”

mY VEHICLE STOPPED IN THE MIDDLE OF THE HIGHWAY AND WAS UNABLE TO PUT IN DRIVE

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.

-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...

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...

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...

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 .

SECOND TIME IN LESS THAN A MONTH ON A 2018 BUICK ENCLAVE THAT AIR CONDITIONING UNIT/EVAPORATOR IN VEHICLE IS NOT WORKING AND VEHICLE IS BLOWING HOT AIR ONLY. THIS OCCURS WHETHER VEHICLE IS IN MOTION OR STATIONARY. THIS HAPPENS WHEN VEHICLE IS FIRST POWERED ON OR OVER AN EXTENDED DRIVE (45 MINS). DOES NOT OSCILLATE WITH CHANGE IN SPEED. DOES NOT OSCILLATE WITH LENGTH OF DRIVE. HOT AIR BLOWS THE ENTIRE TIME AND NOISE COMES FROM DASH THAT SOUNDS LIKE HYDRAULIC DOOR HINGE.

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...

I PURCHASED A NEW 2018 ENCLAVE IN SEPTEMBER OF 2018. I RECEIVED A RECALL LETTER FOR THE VEHICLE SOMETIME DURING THE SPRING 2019 SO I WENT TO MY DEALER SERVICE DEPARTMENT TO GET IT CHECK AND I WAS TOLD EVERYTHING WAS FINE. THEN IN SEPTEMBER I NOTICED THE CHECK ENGINE LIGHT CAME ON AND THE VEHICLE WOULD NOT ACCELERATE PROPERLY SO I TOOK IT TO THE DEALER SERVICE DEPT. ASAP. THEY TOLD ME THERE WAS AN ISSUE WITH THE TRANSMISSION. THEY SAID THAT BECAUSE I HAD LESS THAN 5,000 MILES THIS ISSUE SHOULD NOT BE OCCURRING. IT'S BEEN 4 MONTHS AND I HAVE NOT RECEIVED A REASONABLE TIME FRAME FOR WHEN MY VEHICLE WILL BE READY. MY RIGHTS AS A CONSUMER HAVE BEEN VIOLATED BECAUSE I RECEIVED A DEFECTIVE VEHICLE, WHICH PUT MY FAMILY AND I AT RISK. THE SAME DEALERSHIP OFFERED TO GIVE ME A LOANER VEHICLE THAT ENDED...
