Ford Freestyle security light activation and engine cutoff issue persists after replacing computer, throttle body, and alternator on Ford Freestyle

Some Ford Freestyle owners report experiencing persistent issues with security light activation and engine cutoff, even after replacing key components like the computer, throttle body, and alternator. These issues can manifest through symptoms of a bad throttle body, including poor vehicle performance, dirt buildup, and erratic idling, which may trigger the check engine light. Additionally, some owners have noted their engines shutting off without warning, potentially linked to the security light problems. Intermittent security light events, engine hiccups, and unexpected engine stoppages may indicate deeper underlying issues that require attention. Furthermore, the engine failsafe mode may activate due to certain faults, limiting performance while allowing for limited driving. Owners are advised to perform diagnostic testing with a professional-grade scan tool and consult a mechanic or dealership specializing in Ford vehicles to accurately diagnose and resolve these ongoing issues.
