2020 Jeep Compass Auto Start Stop Not Working

If you own a 2020 Jeep Compass, you may have encountered an issue with the auto start-stop system not functioning as expected.

The auto start-stop feature is designed to enhance fuel efficiency by automatically turning off the engine when the vehicle comes to a stop and restarting it when the driver releases the brake pedal. However, there are several common reasons why this feature may not be working properly.

In this article, we will explore some of the potential issues and provide possible solutions to help you get your auto start-stop system back in working order.

Common Causes of Auto Start-Stop Not Working

There are several factors that can contribute to the auto start-stop system failing to operate as intended. Some of the most common causes include:

  • Low battery voltage
  • System fault or error code
  • High demand for electrical power
  • Excessive outside temperature
  • System not fully warmed up

Possible Solutions

Depending on the root cause of the issue, there are several troubleshooting steps and potential solutions that you can try to resolve the auto start-stop problem on your 2020 Jeep Compass. Here are some steps you can take:

Check The Battery

One of the most common reasons for the auto start-stop system not working is a low battery voltage. If the battery is not sufficiently charged, the system may be disabled to ensure that there is enough power to start the engine when needed. To address this, you can try the following:

  • Inspect the battery for any signs of corrosion or damage.
  • Test the battery’s voltage using a multimeter. A healthy battery should have a voltage reading of around 12.6 volts.
  • If the battery voltage is low, you can try recharging the battery or have it tested and replaced if necessary.

Check For Error Codes

If there is a system fault or error code causing the auto start-stop to malfunction, it is important to diagnose the issue using a diagnostic scanner or OBD-II code reader.

This will allow you to retrieve any stored fault codes and troubleshoot the specific problem that is preventing the system from operating correctly.

Reduce Electrical Load

In some cases, a high demand for electrical power from auxiliary systems such as the air conditioning or heating may disable the auto start-stop feature. You can try turning off any unnecessary electrical loads to see if this resolves the issue.

Manage Outside Temperature

Extreme outside temperatures, particularly during very hot or very cold weather, may cause the auto start-stop system to deactivate.

This is a normal operational characteristic to ensure driver comfort and vehicle performance. If this is the case, allow the vehicle to reach a more moderate temperature range for the system to function again.

Allow For Warming Up

In certain driving conditions, such as during initial vehicle startup or in extremely cold weather, the auto start-stop system may be disabled until the drivetrain reaches the optimal operating temperature.

Allowing the vehicle to warm up by driving it for an extended period may help re-enable the auto start-stop function.

Consult A Professional

If you have attempted the above steps and the auto start-stop system still does not work, it is advisable to consult with a qualified mechanic or authorized Jeep service center for further diagnosis and repair.

They will have the expertise and tools necessary to accurately identify and resolve any underlying issues with the system.
