Chevrolet Tracker engine shuts off while driving, sometimes restarts after sitting on Chevrolet Tracker

Some Chevrolet Tracker owners report experiencing engine shutdowns while driving, which may unexpectedly restart after sitting for a period. These issues can be attributed to several potential causes, including problems with the fuel system, such as a faulty fuel pump or low fuel pressure, which can lead to unexpected engine cut-offs. Additionally, issues with the ignition system, like bad spark plugs or a faulty ignition switch, may result in frequent misfires and engine shutdowns. Some owners have noted that a failing Engine Control Unit (ECU), particularly when exposed to heat, can cause intermittent engine shutdowns. A broken or stretched timing belt can also contribute to low power output and engine stalling while driving. Furthermore, engine overheating is a common reason for sudden engine failure. To address these issues, it is recommended that owners scan for error codes, check fuel pressure, and inspect components such as the crankshaft position sensor and fuel pump relay. Consulting a qualified mechanic is advisable for proper diagnosis and resolution of these concerns.
