Owners of the 2021 Buick Encore frequently report issues with the turbocharger, including failures that lead to significant power loss, particularly when attempting to accelerate or drive uphill. Symptoms described include the vehicle losing power, especially at highway speeds or in wet conditions, and the activation of warning lights such as the check engine light. These issues often occur after approximately 20,000 miles on a replaced turbocharger. One owner specifically notes a dangerous situation involving a near collision due to sudden power loss while passing. Additionally, a connection between turbocharger issues and brake assist problems is mentioned, with hard brake pedals and reduced braking effectiveness occurring intermittently. These complaints indicate potential safety risks, making it important for prospective buyers to consider these patterns when evaluating the vehicle.

Owners report several engine-related issues with the 2021 Buick Encore. One common problem involves overheating, with symptoms such as the temperature gauge rising, loss of power, and smoke from the tailpipe, often leading to recommendations for extensive repairs like engine and turbo replacement. This issue is noted at high mileages, around 121,530 miles. Another issue involves the flex pipe, where owners describe it melting without signs of damage or tampering, necessitating costly repairs not covered by warranty. Additionally, some owners experience persistent check engine lights due to a faulty purge sensor, affecting emissions compliance shortly after acquiring the vehicle. These complaints highlight potential safety concerns, including loss of power and overheating, which could impact vehicle operation.
