Problem overview

Some Mazda CX-7 owners report experiencing loss of power, which often manifests as intermittent power loss without the engine shutting off. Additionally, dashboard lights illuminating and the vehicle becoming locked with no power or steering may indicate a more serious electrical issue. Some owners have linked loss of power while driving to problems within the transmission and electrical system. Furthermore, a faulty or dirty mass air flow sensor (MAF) has been reported to cause power loss, uneven engine running, misfires, and poor exhaust emissions. Given these potential issues, it is advisable for owners experiencing such symptoms to seek a professional inspection to accurately diagnose the root cause of the power loss in their Mazda CX-7.
