Many people mistakenly believe that a dead battery that needs a jump start often (or a car that simply does not start) is a sign of a bad battery that needs to be replaced. Sure, a battery can stop holding a charge and stop working as it should but if replacing the battery does not resolve the issue, then it is important to look further. Besides the car not starting because of a dead battery, other warning signs of a defective ignition system include a vehicle that continues to stall, dashboard lights that flash, and a key that will not turn, for example. A new car should never have these issues.
