The 2024 Buick Encore and Envista has been reported to have several engine-related issues, particularly with the 1.4-liter turbocharged engine. 


























A. Nature of Problems 

Common problems include:


1. Engine Problems  A class action states the "engines were prone to premature internal failure, including bearing and connecting-rod damage, oil leakage, loss of propulsion, and fire. Defendant knew that the Engine System Defect would cause the symptoms described above, including sudden loss of power, smoke, fluid discharge, and engine seizure."  

2. Turbocharger Failure: Many owners have experienced blown turbochargers, which can lead to performance issues and a Check Engine Light. 

3. Cooling System Problems: The engine's cooling system is prone to leaks and overheating, especially in early model years. 

4. Electrical System Issues: Some owners have reported problems with the infotainment system, which can affect the vehicle's performance. 

5. Class Action Lawsuit: There is a class action lawsuit alleging that certain 2024 Buick Encore engines have defects that can cause sudden power loss and potential fire hazards.   Owners are advised to monitor their vehicles for warning lights and symptoms of engine trouble, and consider regular maintenance to prevent these issues.

C. Remedies 

Purchase of a defective 2024 Buick Encore or Envista can give rise to several different legal claims.  

Breach of express warranty

Express warranties can arise from the written new‑vehicle warranty booklet, certified pre‑owned warranty, or dealer service contracts.  A breach occurs when the vehicle has problems covered by that warranty and GM or the dealer fails to repair within a reasonable number of attempts.  

Breach of implied warranties

The implied warranty of merchantability requires that the Encore be fit for ordinary use, reasonably safe, and of at least fair average quality compared to similar vehicles.  Recurring engine, transmission, or safety defects can show it is not merchantable.

Magnuson‑Moss Warranty Act
The Magnuson‑Moss Warranty Act is a federal statute that makes it easier and more economical for consumers to enforce written and implied warranty rights on cars like the 2024 Encore.

Deceptive practices and consumer fraud
Claims may also be made for deceptive or unfair practices under state consumer protection laws (e.g., New Jersey Consumer Fraud Act and analogous statutes).
