I purchased this used 2016 Buick Enclave in July 2026. Shortly after purchase, the vehicle began repeatedly jerking and hesitating while driving. During occurrences, Traction Control/StabiliTrak warnings appeared and the vehicle experienced loss of power and difficulty accelerating normally. I reported the jerking/drivability problem to the selling dealer. On July 27, 2026, the selling dealer attempted a repair after I reported the jerking/drivability problem. Within approximately five minutes of leaving the dealership, the vehicle began jerking again. I then took the vehicle to an auto-parts store, where an OBD-II scan produced multiple diagnostic trouble codes, including P0300 engine misfire and several MAP-sensor-related codes. I have photographs documenting the scan results. The vehicle became disabled shortly thereafter and required towing. It was subsequently evaluated by an independent repair facility, where the MAP sensor was replaced. The vehicle later again experienced the jerking/loss-of-power condition and StabiliTrak/Traction Control warnings. On August 10, the vehicle became disabled again. These incidents have occurred while driving in traffic. When the condition occurs, I cannot reliably accelerate or maintain normal vehicle operation, creating a safety concern because I may be unable to move safely with surrounding traffic. The specific cause is UNKNOWN. The vehicle has been evaluated by the selling dealer and an independent repair facility and is being taken to an authorized Buick dealership for further diagnosis. The vehicle is available for inspection.

My car shutters and shakes when switching gear. My mechanic believes it’s transmission and or torque. My mechanic said he has fixed at least 6 of them recently as well and is very surprised there is no recall

Driving vehicle would not get out of first gear. Decide to get vehicle home so I turned around and found that I did not have reserve also. On way back home transmission made a loud clunking sound and the check engine light came on. Was able to get home and park the car. Called tow truck to take to the dealers. This vehicle only has 23,773 miles on it. Dealer had to overhaul 3-5-r clutch housing.

Transmission failure at 27,125 miles. While at a stop sign at a busy intersection, went to proceed and had no power to move. Engine was running fine. Got vehicle to a dealership and they found 3-5 reverse snap ring groove had sheared off and metal went throughout the transmission. Dealership informed me they had four similar issues in the past couple of months.
