We’ve all been there. You’re running late for work, you jump in the car, turn the key and… nothing. Your engine won’t start. Uh oh. Chances are, you’ve got a problem with your starter motor.
The starter motor is a small but powerful electric motor that’s responsible for turning over your engine when you turn the key or press the start button. It’s usually mounted on the engine or transmission, and engages with the flywheel to crank the engine.
Over time, starter motors can wear out or fail. The good news is that they usually give some warning signs before they die completely. Here are some of the most common symptoms of a failing starter motor:
Slow or laboured cranking: If your engine is cranking more slowly than usual, or sounds like it’s struggling to turn over, this is often the first sign that your starter motor is on the way out.
Grinding noises: If you hear a grinding noise when you try to start your car, it could mean that the starter motor is not engaging properly with the flywheel. The starter drive gear may be worn out or not engaging fully.
Freewheeling: This is when you hear a whining noise when you try to start the engine, but the engine doesn’t actually crank. It means the starter motor is spinning, but not engaging with the flywheel.
Clicking: A single click or no sound at all when you turn the key could indicate a problem with the starter solenoid or motor.
Smoke or a burning smell: This could mean the starter motor is overheating due to drawing excess current. It may be caused by a short circuit, a problem with the ignition switch, or simply overuse.
So what causes starter motors to fail? It could be due to worn out or damaged parts like the solenoid, brushes, or armature. Loose or dirty wiring can also cause problems. Sometimes, the starter motor just wears out due to age and usage.
If you suspect your starter motor is failing, it’s best to get it checked out sooner rather than later. Continuing to use a damaged starter motor can cause further damage to the flywheel and other components.
Rebuilding a starter motor is often more cost-effective than replacing it with a new one. A rebuilt starter will usually outlast a new aftermarket one since the older units are generally better quality.
In New Zealand, the cost to rebuild or replace a starter motor can vary depending on the make and model of your vehicle, and the specific repairs required. As a rough guide, you can expect to pay somewhere between $350 to $850+ for a starter motor replacement.
