Dead Battery

A dead battery leaves you stranded, but the fix is usually quick — as long as the battery is the actual problem.

A dead battery means there isn't enough charge to crank the engine. You'll hear a rapid clicking when you turn the key, or nothing at all. The most common causes are leaving lights or accessories on, a battery that's reached the end of its life (typically 3 to 5 years), or a parasitic drain pulling power while the car sits. A jump start will get you going, but if the battery keeps dying, something deeper is going on.

Before buying a new battery, have the charging system tested. A failing alternator won't recharge the battery while driving, so even a new battery will die quickly. A parasitic draw test can identify if something — like a stuck relay, aftermarket radio, or malfunctioning module — is draining the battery overnight. Testing the battery's cold cranking amps (CCA) with a load tester reveals whether it can still hold a charge.
