5/5 Overall
NHTSA 5-Star Safety Rating
Complaints for the 2018 Buick Enclave cluster most heavily around brakes, the powertrain, and the engine. On the brake side, owners report brake fade, longer stopping distances, and pedal feel changes that develop over time. Powertrain complaints center on transmission issues, with owners describing rough shifts, shuddering, and in some cases complete transmission failure at relatively modest mileage, one recurring pattern involves owners being told the transmission is fine by a dealer before it fails outright. Engine-related reports include exhaust leaks traced to broken front exhaust pipes and catalytic converter failures attributed to weld breaks. A smaller cluster of complaints touches on the air conditioning system failing to defog the windshield adequately, particularly in wet or humid conditions, which owners say affects visibility.
