At what mileage does a starter go bad?

The starter in a car is a crucial component that helps turn the engine over and start the vehicle. However, like any other part, the starter can eventually wear out and fail. The typical lifespan of a car starter is around 100,000 to 150,000 miles, but several factors can cause it to go bad sooner.


Factors That Affect Starter Lifespan



  • Frequent Use: Vehicles that are started and stopped frequently, such as delivery vans or taxis, will put more strain on the starter and cause it to wear out faster.

  • Environmental Conditions: Extreme temperatures, moisture, and exposure to road debris can all contribute to faster starter wear and tear.

  • Electrical Issues: Problems with the battery, alternator, or wiring can overload the starter and shorten its lifespan.

  • Age: Even if the mileage is low, older starters are more prone to failure due to general wear and tear over time.


It's important to note that the mileage at which a starter goes bad can vary significantly based on these factors. Regular maintenance and monitoring the health of the starter and related electrical components can help extend its lifespan.


Signs of a Failing Starter



  • Clicking or grinding noises when turning the key: This can indicate the starter is struggling to engage the flywheel.li>
  • Slow or delayed engine cranking: If the engine takes longer than usual to start, it may be a sign the starter is weakening.

  • No response when turning the key: A completely failed starter will result in no engine cranking at all when the key is turned.


If you notice any of these symptoms, it's best to have the starter inspected by a mechanic as soon as possible to avoid being stranded with a non-starting vehicle.

How many miles do starters last?


How long should a starter last? Most starters are designed to last between 80,000 to 150,000 miles, depending on the manufacturer and driving conditions. However, if you're experiencing starting problems or notice any signs of failing, it's likely time to replace your starter.



Is it common for a starter to go bad?


Starters do wear out or fail over time. However, they usually have several warning signs that they're on the way out, and mechanics may ask you about them if you take your vehicle into an auto repair shop. Your answers will help them diagnose the problem.
