Why is my Lexus clicking but not starting?
Hearing a clicking sound when you try to start your Lexus can be frustrating and worrisome. This issue is relatively common and can stem from a variety of causes, ranging from minor to more serious mechanical problems. In this article, we’ll explore the potential reasons behind this issue and provide guidance on what steps you can take to resolve it.
Common Causes of a Clicking Sound When Starting Your Lexus
When your Lexus clicks but doesn’t start, it’s often a sign that the electrical or mechanical systems involved in starting the engine are not functioning properly. Below are some of the most common causes:
- Weak or Dead Battery: A weak or dead battery is the most common reason for a clicking sound. The starter motor requires a significant amount of power to turn the engine over, and if the battery doesn’t have enough charge, it may only produce a clicking noise.
- Faulty Starter Motor: The starter motor is responsible for cranking the engine. If it’s worn out or malfunctioning, it may produce a clicking sound without engaging the engine.
- Corroded or Loose Battery Connections: Corrosion or loose connections at the battery terminals can prevent the electrical current from reaching the starter motor, leading to a clicking noise.
- Bad Alternator: If the alternator isn’t charging the battery properly, the battery may not have enough power to start the car, resulting in a clicking sound.
- Engine Mechanical Issues: In rare cases, internal engine problems, such as a seized engine, can prevent the engine from turning over, causing the starter to click.
Steps to Diagnose and Fix the Problem
To address the issue, follow these steps to diagnose and potentially resolve the problem:
- Check the Battery: Use a multimeter to test the battery voltage. A healthy battery should read around 12.6 volts when the car is off. If the voltage is low, try jump-starting the car or replacing the battery.
- Inspect Battery Connections: Look for corrosion or loose connections at the battery terminals. Clean the terminals with a wire brush and ensure the connections are tight.
- Listen for the Clicking Sound: Pay attention to the location of the clicking noise. If it’s coming from the starter motor, the issue may lie with the starter itself.
- Test the Alternator: If the battery is charged but the car still won’t start, have the alternator tested to ensure it’s functioning properly.
- Consult a Professional Mechanic: If you’ve tried the above steps and the problem persists, it’s time to bring your Lexus to a trusted auto repair shop for a thorough diagnosis. A professional mechanic can inspect the starter motor, alternator, and engine for any underlying issues.
Preventative Maintenance Tips
To avoid encountering this issue in the future, consider the following maintenance tips:
- Regularly inspect and clean your battery terminals to prevent corrosion.
- Replace your car battery every 3-5 years or as recommended by the manufacturer.
- Have your alternator and starter motor checked during routine maintenance visits.
- Pay attention to warning signs, such as dimming headlights or slow cranking, which may indicate battery or alternator issues.

Why is my car not starting but making a clicking sound?
The clicking noise it is making combined with the engine not starting can be caused either by a dead vehicle battery or an issue with a loose, corroded, or damaged battery cable connection at the battery itself.

- Intermittent vehicle starting problems.
- Whirring, grinding, or clicking when you turn the key or press start.
Why is my car not starting but the battery isn't dead?
Bad alternator
Connected to the battery is the alternator, which works to generate power for your vehicle's electrical components. When you have a brand-new battery but still can't start the car, the alternator might be the issue. Cold and damp climates may increase wear on an alternator, causing it to fail.
Can you jump-start a car with a bad starter?
While jump-starting your car despite having a bad starter is possible, it's best to replace the faulty part as soon as possible.
