2018 Jeep Compass Auto Start Stop Not Working

Many 2018 Jeep Compass owners have encountered issues with the auto start-stop feature not working as intended.

If you’re one of those individuals, you’re not alone. The auto start-stop system is designed to improve fuel efficiency and reduce emissions by automatically shutting off the engine when the vehicle comes to a stop, and then restarting it when the driver releases the brake pedal.

However, when this system malfunctions, it can be frustrating and concerning for Jeep Compass owners.

Possible Causes of Auto Start-Stop Not Working

There are several potential reasons why your 2018 Jeep Compass auto start-stop feature is not functioning properly. It’s important to understand these causes so that you can effectively address the issue. Some common reasons for the auto start-stop not working include:

  • Battery Issues: If your vehicle’s battery is not functioning optimally, it can negatively impact the auto start-stop system. A weak or faulty battery may prevent the system from operating as intended.
  • Temperature Conditions: Extreme temperatures, especially cold weather, can affect the performance of the auto start-stop feature. In colder climates, the system may not engage to preserve the battery and ensure proper vehicle operation.
  • High Electrical Load: When your Jeep Compass is experiencing a high electrical load due to various components running simultaneously, such as the air conditioning, heating, and entertainment systems, the auto start-stop feature may be temporarily disabled to prioritize vehicle functionality.
  • System Malfunction: In some cases, the auto start-stop system may experience a malfunction due to a sensor issue, software glitch, or other technical problems within the vehicle’s electronics.

Steps to Address The Issue

Dealing with a malfunctioning auto start-stop system can be frustrating, but there are steps you can take to diagnose and potentially resolve the problem. Here’s what you can do:

Check The Battery

Begin by checking the status of your Jeep Compass’s battery. If it’s old or showing signs of weakness, such as slow cranking or difficulty starting the vehicle, it may be time to replace it. A healthy battery is essential for the proper functioning of the auto start-stop system.

Monitor Temperature Conditions

If you live in a colder climate, be mindful of the temperature’s impact on the auto start-stop feature. In extreme cold, the system may not engage, which is normal behavior to protect the battery. However, if the feature consistently fails to operate in moderate temperatures, further investigation may be necessary.

Reduce Electrical Load

Try minimizing the electrical load on your Jeep Compass by adjusting the usage of various systems, such as the air conditioning and entertainment features. By reducing the strain on the vehicle’s electrical system, you may increase the likelihood of the auto start-stop feature functioning as intended.

Consult With A Professional

If the auto start-stop problem persists, it’s advisable to seek assistance from a qualified technician or dealership. They can conduct a comprehensive diagnostic assessment of the system to identify any underlying issues and perform the necessary repairs or adjustments.
