Auto start-stop not working in a vehicle can be caused by several factors, including a weak or faulty battery unable to sustain the demands of the system, a malfunctioning starter or alternator, a defective brake switch or sensor preventing the system from recognizing when the vehicle is stopped, low engine coolant levels triggering the system to remain inactive for safety, or even software glitches in the vehicle’s computer system. Additionally, issues with the air conditioning system, such as low refrigerant levels, can also disable the auto start-stop feature as a precaution. Regular maintenance, such as checking and replacing the battery, ensuring proper brake system function, and addressing any diagnostic trouble codes, can help resolve these issues and restore the functionality of the auto start-stop system in a vehicle.
