5/5 Overall
NHTSA 5-Star Safety Rating
The dominant complaint pattern for the 2019 Buick Enclave centers on the powertrain, with engine stalling and unexpected shutdowns being the most common theme owners describe. Many reports involve the vehicle cutting out while driving, sometimes at highway speeds, often accompanied by a dashboard message indicating the car won't restart due to conditions not being met. Owners describe losing power steering during these events, and some note the vehicle becomes completely inoperable until towed. A handful also describe hesitation and a stumbling sensation during acceleration, as if the engine is about to stall. The auto stop-start system comes up repeatedly in connection with these shutdowns, with owners reporting the engine fails to restart after a stop. Separately, several owners report the air conditioning system blowing only warm air regardless of settings or driving conditions, a pattern that appears across multiple complaints.
