Why won't my car start?

A car that won't start is usually caused by a dead battery, faulty starter motor, or failed alternator. If you hear clicking, the battery is most likely dead. No sound at all often points to the starter. A multimeter test on the battery (should read 12.4-12.7V) helps identify the problem.

Why is my check engine light on?

The check engine light is triggered by the OBD2 system when it detects an emissions or engine performance issue. Common causes include a loose gas cap, faulty O2 sensor, catalytic converter problems, or misfiring spark plugs. Use an OBD2 scanner to read the specific trouble code (e.g. P0300, P0420).

Why are my brakes squeaking?

Brake squeaking is most commonly caused by worn brake pads, glazed rotors, dust buildup, or cheap pad material. A grinding noise means pads are worn to metal-on-metal contact and need immediate replacement. Brake pad replacement typically costs $150–$350 per axle including labor.

Why is my car overheating?

Cars overheat due to low coolant levels, a failed thermostat, broken water pump, radiator leaks, or a blown head gasket. Pull over immediately if the temperature gauge hits the red zone. Running an overheating engine for even 5 minutes can cause $3,000+ in engine damage.

How do I know if my battery is bad?

Signs of a bad car battery include slow cranking, dim headlights, dashboard warning light, and needing frequent jump-starts. Most auto parts stores will test your battery free. A healthy battery should read 12.4–12.7 volts with the engine off. Car batteries typically last 3–5 years.
