The starter motor is one of the most important parts of a car.  It is used to start the engine and if it fails the engine won't turn over.  The starter motor may need replacing if it’s not turning fast enough or if the part is seized.

Signs of a faulty starter motor:

• The engine won't turn over and vehicle won’t start

• Smell or see smoke when starting the motor

• Grinding or whirring noise when starting the engine
  

• Starter engages but doesn't spin the motor

• Sporadic starting issues

• Interior lights dim when starting the car

• Warning Indicator Light on Dashboard

• Dim/Flickering Headlights
