Some Plymouth Grand Voyager owners report experiencing engine shutdowns after about 10 minutes of operation, accompanied by a loss of power steering. This issue may be linked to a failing fuel pump, which can cause the engine to stall during driving, particularly when it reaches normal operating temperature. Owners are advised to use a pressure gauge to check the fuel pump's functionality during these incidents. Additionally, the loss of power steering after restarting the engine may indicate problems within the power steering system, such as leaks or low fluid levels. Furthermore, intermittent stalling while driving, especially at slow speeds or traffic lights, could result from a clogged port, malfunctioning IAC valve, damaged wiring, or a faulty Powertrain Control Module (PCM). Cleaning the throttle body is often a recommended solution for addressing clogged ports. It is crucial for owners experiencing these issues to inspect the relevant components to effectively diagnose and resolve the underlying problems.
