What Causes the Engine Start-Stop Failure in the Regal?

[DelTheo]

Here are the reasons for the engine start-stop failure in the Regal: 1. The battery temperature is too high or too low. 2. The battery charge is too low. 3. The vehicle is on a steep slope. 4. The cabin is being heated or cooled and has not yet reached an acceptable temperature. 5. The engine has not reached normal operating temperature, or the transmission is not in drive mode. Below is additional information about the engine auto start-stop system: 1. Definition of Auto Start-Stop: It is a system that automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) and restarts it when it's time to move forward. 2. Function: During stops at traffic lights or in traffic jams, the system minimizes engine idling time to reduce unnecessary fuel consumption. Turning off the engine when stopped effectively reduces noise and vibration, providing a better driving experience.
