2014 Buick Enclave: engine stalls while driving

Filed Oct 28, 2025 · Fuel system, Transmission · WA

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.

In 2016, and again in 2020 after the dealer first fixed the issue, while driving at high speeds, on highways, also in the rain, again at a stop light, the vehicle suddenly decelerated, causing the potential for a very serious accident. The warnings then displayed on the dash included reduced engine power, service stabilitrak, service traction control, and traction control off. The vehicle only then drove at slow speeds, sputtered and jerked, and felt like it might stall. When able to pull over, at times turning off the car reversed the problem. Sometimes the check engine light was on, sometimes it wasn't. Sometimes it would drive fine and then out of nowhere, it would happen again. In 2016, the dealership had a difficult time finding the issue. After several days of driving it, they identified the problem as a fuse box issue and replaced the fuse box. This seemed to fix the issue until it happened again in 2020 while driving. On a road trip, it happened while on a highway, again at a red light, and while on a highway again. Each time, we pulled over, turned the car off for a while. One time in particular, the issue didn't go away after turning the car back on.
