Why Is My Auto Start Stop Not Working?
Auto Start Stop technology is designed to save fuel by automatically shutting off your engine when the car is stopped. If this function is not responding when you come to a stop, it can be extremely aggravating. Fortunately, this issue can often be resolved without the help of a professional.
Here are some of the most common reasons why your Auto Start Stop may not be working properly:
