Problem overview

Some Chrysler Pacifica owners report experiencing issues where the vehicle starts and then shuts off immediately, potentially due to a malfunctioning security system or key fob. These problems may stem from the smart key's electronic protection failing, leading to abrupt shutdowns after starting. Additionally, some owners encounter difficulties related to the immobilizer system, which requires the correct key fob; faults in this system can prevent the engine from starting or cause it to shut off right away. Battery voltage issues are also reported, where significant drops in voltage may lead to unexpected engine shutdowns. Furthermore, fuel-related problems, such as a failing fuel pump or old gas, can contribute to the engine shutting off shortly after starting. To resolve these issues, owners are advised to check the key fob functionality, inspect the immobilizer system, verify battery voltage, and have the fuel system examined. If problems continue, consulting a qualified mechanic or contacting a Chrysler dealership is recommended for further assistance.
