What are the reasons for engine start-stop failure?

[DeAlina]

Engine start-stop failure may occur due to: 1. The driver not wearing a seatbelt; 2. The car's air conditioning being on, check if the driver's door is open; 3. The battery charge is below 70%, causing the start-stop system to fail; 4. The transmission is not in P or R gear, as the start-stop system only works in P or R gear; 5. The steering wheel angle exceeds 30 degrees, which also disables the start-stop system. The car's start-stop system requires three conditions to activate: first, the engine must be idling and not in gear; second, the wheel speed sensor of the anti-lock system must read 0; third, the electronic battery sensor must have enough charge for the next start.
