The starter motor is a crucial component of your INFINITI vehicle's starting system. It is responsible for initiating the engine's rotation when you turn the key or press the start button. Over time, the starter motor may experience wear and tear, leading to various issues that can affect the starting process. Recognizing the symptoms of a failing starter motor is essential to address the problem promptly and avoid unexpected breakdowns. In this article, we will discuss how to identify the signs of a failing INFINITI starter motor and understand the steps to take for diagnosis and repair.

  1. Engine Cranking Slowly or Not Starting

One of the primary signs of a failing starter motor is when the engine cranks slowly or fails to start altogether. When you turn the key or press the start button, the starter motor should engage quickly and spin the engine at a sufficient speed. However, if the starter motor is faulty, you may notice a delay in engine cranking or a slow rotation, indicating a problem with the motor's power output.

  1. Clicking Sound During Starting

Another common symptom of a failing starter motor is a clicking sound when you attempt to start the engine. If you hear a rapid clicking noise but the engine does not turn over, it usually indicates that the starter solenoid is receiving power but failing to engage the starter motor fully. This can occur due to worn-out internal components or an electrical issue within the starter motor.

  1. Grinding Noise

A grinding noise during engine starting is a clear indication of a failing starter motor. This typically occurs when the starter motor's gear teeth are damaged or worn, causing them to not properly engage with the engine's flywheel. The grinding noise is a result of the gear teeth grinding against each other, indicating the need for immediate attention and repair.

  1. Frequent Need for Jump-Starting

If you find yourself frequently needing to jump-start your INFINITI vehicle, it could be a sign of a failing starter motor. While a dead battery is often the first assumption, a faulty starter motor can also cause battery drain. The excessive current draw from a failing starter motor can lead to a weakened battery over time, requiring jump-starts to get the engine running.

  1. Electrical Issues

A failing starter motor can also manifest as various electrical issues within your INFINITI vehicle. You may experience intermittent problems with other electrical components, such as dimming headlights, flickering dashboard lights, or erratic behavior of the radio or power windows. These issues occur because a failing starter motor can draw excessive electrical power, affecting the overall electrical system's performance.


Recognizing the signs of a failing INFINITI starter motor is crucial for maintaining the reliability and performance of your vehicle. If you experience any of the symptoms mentioned, it is recommended to have your INFINITI inspected by a qualified technician who can accurately diagnose the problem and perform the necessary repairs or replacement. Ignoring a failing starter motor can lead to unexpected breakdowns and inconvenience. Timely identification and resolution of starter motor issues will ensure a smooth and reliable starting experience for your INFINITI vehicle.
