Chevrolet Malibu relay switch overheating issue causing starting failure on Chevrolet Malibu

Problem overview

Some Chevrolet Malibu owners report experiencing starting failures due to relay switch overheating issues. These problems may stem from the relay's critical role in controlling current flow to the starter motor, and if it malfunctions, other issues such as a blown starter fuse or ignition switch failure could also be to blame. Additionally, some owners have noted that a bad alternator can lead to insufficient battery power, further complicating starting attempts. When diagnosing these issues, it is important to determine whether the vehicle is cranking or if the starter is not engaging, as this can indicate different underlying problems. Furthermore, some Malibu owners report encountering an "Engine Power Reduced" notification, which may accompany deacceleration or stalling. Addressing these concerns promptly is essential to ensure reliable vehicle operation.
