Are you wondering why your car won’t start? This could be the result of starter failure, which can be a nightmare if you don't know what caused it or how to fix it. Keep reading to discover several common causes of starter failure.

1. Loose Wiring

Loose wiring to and from the starter can lead to a disconnection between the starter components and the dashboard controls, causing starter issues.

2. Battery Corrosion

If you notice white, blue, or green residue covering the cables and terminals on your car battery, battery corrosion may be the cause of starter problems. Battery corrosion typically leads to poor battery performance, which can bring about weak or total electrical power disruption to the starter.

3. Solenoid Issues

The solenoid is a switch that connects power from the engine to the starter. If the solenoid has issues such as poor wiring, a blown fuse, or has experienced excessive wear and tear, it can affect the starter's efficiency.

4. Oil Leaks

Oil leaks are another common cause of starter issues. What might start out as a small or slow oil leak can end up soaking the starter, leading to starter damage and failure.

5. Bad Relay or Fuse

A relay is an electromagnetic switch that is connected to the starter system. When damaged, it cuts off the electric supply to the starter component, preventing your car from starting.

6. Dirty Motor

Grime, dust, and small metal fragments can cause damage to the electrical system between the battery and the starter. This restriction of power can lead to starter failure.

7. Natural Wear and Tear

Over time, the starter and other electrical components will experience natural wear and tear. Worn-out parts of the starter accelerate its deterioration and are a common cause of failure.
