Jeep Cherokee unable to exceed 4 mph after warming up on a cool morning on Jeep Cherokee

Some Jeep Cherokee owners report experiencing issues that prevent their vehicle from exceeding 4 mph after warming up on cool mornings. These problems may include intermittent power loss, resulting in jerky movements at low speeds. Additionally, some owners find that their engine consistently shuts down once it reaches operating temperature and fails to restart immediately, which could indicate a lack of spark from the distributor. An engine temperature hot warning, along with autostart disabled, may suggest a malfunctioning coolant temperature sensor or related components. Owners also report bucking or missing while driving, pointing to potential engine performance or fuel delivery issues. Furthermore, difficulties speeding up without engaging the ICE (Internal Combustion Engine) and inconsistent heating or cooling in electric-only mode may be linked to hybrid system malfunctions or battery problems. High RPMs while stuck at idle after warming up could be associated with the Idle Air Control (IAC) valve or Throttle Position Sensor (TPS) issues. Lastly, some owners experience engine stalling when warm, possibly due to the PCM relying on its sensors and the ASD cutting off ignition due to the coolant temperature sensor detecting a hot engine. It is advisable for owners facing these symptoms to have their vehicle inspected by a qualified mechanic for proper diagnosis and resolution.
