“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.…”
