Understanding the Stop Start System Fault
When the stop start system in your Nissan Qashqai malfunctions, it may fail to restart the engine after coming to a stop or stop the engine unexpectedly during driving.
This fault can be caused by various underlying issues that need to be identified and addressed promptly to ensure the proper functioning of your vehicle.
Common Symptoms of Stop Start System Fault
Common symptoms of a stop start system fault in a vehicle like the Nissan Qashqai include:
Engine Fails to Start
One of the most obvious signs of a stop start system fault is when the engine fails to start after the vehicle has come to a stop.
You may notice that the engine does not restart automatically when you lift your foot off the brake pedal.

Another symptom is the engine stopping unexpectedly while driving, even though you haven’t come to a complete stop.
This can happen intermittently and is often accompanied by dashboard warning lights indicating a system fault.
Warning Lights on Dashboard
If there’s a fault in the stop start system, you might see warning lights illuminated on your Nissan Qashqai’s dashboard.
These lights can indicate issues with the engine, battery, or other related components that are essential for the proper functioning of the stop start system.
Causes of Stop Start System Fault
Understanding the root cause of the stop start system fault is crucial for effective diagnosis and repair.
Here are some common reasons why your Nissan Qashqai’s stop start system may malfunction:
Battery Issues
A weak or faulty battery can prevent the stop start system from restarting the engine after it shuts off.
This could be due to an old battery that needs replacement or issues with the battery’s charging system.
Starter Motor Problems
If the starter motor in your Nissan Qashqai is malfunctioning, it may not have enough power to restart the engine when required by the stop start system. This can result in intermittent starting issues or complete failure to start.
Faulty Sensors
The stop start system relies on various sensors to monitor conditions such as battery voltage, engine temperature, and brake pedal position.
If any of these sensors are faulty or incorrectly calibrated, it can lead to errors in the system’s operation.
Diagnostic Steps to Identify the Issue
To pinpoint the exact cause of the stop start system fault in your Nissan Qashqai, follow these diagnostic steps:
Checking Battery Health
Use a multimeter to test the voltage and overall health of your Nissan Qashqai’s battery. Ensure it meets the manufacturer’s specifications for optimal performance.
Testing Starter Motor Functionality
Perform a starter motor test to check if it is operating correctly and generating enough power to start the engine consistently.
Scanning for Error Codes
Use an OBD-II scanner to retrieve error codes stored in your vehicle’s computer system. These codes can provide valuable insights into specific problems affecting the stop start system.
Steps to Fix Stop Start System Fault Nissan Qashqai
Once you’ve identified the cause of the stop start system fault, take appropriate measures to resolve the issue:
Replacing or Charging the Battery
If the battery is at fault, replace it with a new one that meets the specifications recommended by Nissan. Alternatively, recharge the battery if it’s determined to be in good condition but low on charge.
Repairing or Replacing the Starter Motor
Address any issues with the starter motor by either repairing it if possible or replacing it with a new one. Ensure the replacement part is compatible with your Nissan Qashqai’s model and year.
Sensor Calibration or Replacement
Calibrate or replace faulty sensors that are contributing to the stop start system fault. Proper calibration ensures accurate readings and seamless operation of the system.
Diagnostic Steps to Identify the Issue
To minimize the risk of encountering stop start system faults in your Nissan Qashqai, follow these preventive maintenance tips:
Regular Battery Checks
Periodically inspect the battery for signs of corrosion, leaks, or deterioration. Clean the terminals and connections to maintain good electrical contact and prolong battery life.
Keeping Sensors Clean and Functional
Keep sensors clean from dirt, debris, and moisture that can affect their performance. Regularly inspect and replace sensors as recommended by Nissan to ensure accurate data input for the stop start system.
Driving Habits to Maintain Battery Health
Avoid frequent short trips and excessive idling, as these can drain the battery faster and put more strain on the stop start system. Opt for longer drives whenever possible to allow the battery to recharge fully.
