Experiencing a situation where your Nissan Murano won't start and the brake pedal feels locked can be frustrating. This issue often arises due to a malfunctioning brake switch, electrical problems, or other mechanical failures. Understanding the potential causes and solutions can help you address the problem effectively.

Common Causes of Starting Issues and Brake Lock

When your Nissan Murano won't start and the brake pedal is hard to depress, consider the following potential causes:

  • Brake Light Switch Failure: The brake light switch is crucial for starting the vehicle. If it malfunctions, it may prevent the car from recognizing that the brake pedal is pressed, thereby inhibiting the start function.

  • Obstructed Brake Pedal: Sometimes, floor mats or other items can obstruct the brake pedal's movement, making it feel locked. Check for any objects that might be preventing full pedal depression.

  • Ignition or Electrical Issues: Problems with the ignition switch or wiring can also lead to starting difficulties. Ensure that all electrical connections are secure and functioning properly.

  • Battery Problems: A weak or dead battery may provide enough power for lights but not enough to start the engine. Testing the battery voltage is essential.

Steps to Troubleshoot

If you encounter this issue, follow these troubleshooting steps:

1. Check for Obstructions: Inspect the area around the brake pedal for any items that may be blocking it. Remove any obstructions.

2. Test the Brake Light Switch: Have someone observe your brake lights while you press the pedal. If they do not illuminate, you may need to replace the brake light switch.

3. Attempt to Start in Neutral: Sometimes shifting into neutral can help bypass issues related to gear selection. Try starting the vehicle while in neutral.

4. Pump the Brake Pedal: If the brake feels stiff, try pumping it several times before attempting to start the vehicle. This can sometimes reset the system.

5. Check Battery Voltage: Use a multimeter to check if your battery voltage is between 12.4V and 12.6V. If it's lower, consider jump-starting or replacing the battery.

When to Seek Professional Help

If these steps do not resolve the issue, it may be time to consult a professional mechanic. They can perform a thorough diagnosis to identify whether there are deeper electrical issues or if components like the master cylinder need replacement.

Important Note

It's crucial to address these issues promptly as they can lead to safety concerns while driving. If you experience repeated problems with starting or braking, consider reporting them to Nissan as they may relate to known recalls or technical service bulletins (TSBs).
