Buick Enclave stalling and shuddering issue at front despite battery and fuse box relay replacement on Buick Enclave

Some Buick Enclave owners report experiencing stalling and shuddering issues even after replacing the battery and fuse box relay. These problems may stem from fuel issues, such as bad gas or water in the gas tank, which can cause the engine to run rough or stall. Additionally, some owners have reported severe launch shudders in certain gears, indicating potential transmission problems. The Buick Enclave is also known for common issues, including transmission problems, HVAC actuator issues in specific model years, stretched timing chains in first-gen models, and brake problems in later models. Furthermore, electrical system issues have been reported by Enclave owners, which could contribute to stalling and shuddering. Other factors, such as the condition of spark plugs, air filters, and sensors, can also lead to performance issues. Given the complexity of these potential causes, it is advisable for owners to consult a professional mechanic for an accurate diagnosis and effective resolution of the stalling and shuddering problems.
