“The car can refuse to start right after it has been driven and shut off or after it has been parked for a while. It has been happening alot in the last three months. We have had to replace the alternator and battery,that were all replaced early this year by previous owner. Sometimes jumping the car works and other times it does not. The problem started one day while driving at low speeds. The brake light and battery signs appeared on the dash and disappearing after that,the car started to refuse starting and needed a jump. We installed a new battery days ago and the car started right up. …”
