NHTSA Complaint #11696098 — 2014 BUICK ENCLAVE

The vehicle began shuddering and losing power during normal driving. The issue occurs at various speeds, especially between 35–60 mph, and feels as though the car is slipping or will stall. A certified service center diagnosed a failing torque converter, which is part of the transmission/power train. The repair estimate was several thousand dollars. This failure poses a safety risk because the vehicle can suddenly lose acceleration or struggle to move in traffic. The service center confirmed the defect but stated there is no recall or assistance from Buick or GM. I have contacted Buick Customer Care and GM Executive offices with no response. The vehicle remains unsafe to drive.
