Problem overview

Some 2006 Subaru Outback owners report experiencing issues such as the check engine and cruise control lights illuminating alongside a loss of power during acceleration. These problems may stem from a misfiring engine, which can lead to incomplete combustion and trigger the check engine light. Additionally, faulty ignition coils are commonly cited as a cause of engine performance issues, affecting the high voltage needed for spark plugs and consequently impacting overall engine function. Some owners also report concerns with the Engine Control Module (ECM), which is essential for diagnosing engine issues; problems with the ECM can result in performance complications and warning lights. Furthermore, a malfunctioning cruise control switch may cause the cruise control light to blink, indicating potential issues with the cruise control system itself. It is advisable for owners experiencing these symptoms to consult a mechanic for a thorough diagnosis and appropriate solutions.
