Problem overview

Some Cadillac SRX owners report experiencing intermittent starting issues, which may be linked to problems with the throttle body or worn spark plug boots. These starting problems can stem from various factors, including failures in the electrical or fuel systems, such as a dead battery, alternator issues, or a malfunctioning starter. Additionally, some owners find that if the engine cranks but does not start, it may indicate complications with air, fuel, or spark delivery. Soft misfires or surges during starting are also reported, suggesting potential underlying issues like poor connections between the battery and starter or a failing starter. To effectively diagnose and resolve these intermittent starting problems, a thorough inspection of the electrical system, including the throttle body, spark plug boots, battery connections, and starter, is recommended.
