Is my Mokka stop-start ok?
Don't worry, all stop-start systems in all cars exhibit these tendencies. The stop-start system will only work if the engine's computer reckons everything is well with the battery condition and any demand on the battery. It will also limit the number of stop-starts it does in a given time to preserve the starting motor. There's nothing to worry about. If it stops working entirely then it's worth getting your battery checked.
