💡 Pro Tips:

1. Check for Software Updates: Sometimes, issues with the auto start-stop feature can be resolved by updating the vehicle’s software. Contact your Jeep dealership to see if there are any available updates for your 2018 Jeep Compass.

2. Check the Battery Connection: Ensure that the battery connections are secure and free of corrosion. Loose or corroded connections can affect the auto start-stop system’s functionality.

3. Consult a Different Dealer or Mechanic: If you’re not satisfied with the recommendation or service provided by your current dealer, consider seeking a second opinion from another dealership or mechanic. They may have a different insight into the issue and potentially offer a more cost-effective solution.

4. Test the Auto Start-Stop System: Perform a thorough test of the auto start-stop system by following the manufacturer’s instructions in the vehicle’s manual. This can help determine if the issue lies with the system itself or other related components.

5. Join Online Jeep Communities: Connect with other Jeep Compass owners through online forums or communities dedicated to Jeep enthusiasts. These platforms can provide a wealth of knowledge and experiences, allowing you to see if others have encountered similar issues and how they resolved them.

1. Dealer’s Recommendation: Replacing Batteries For $600

The person discussing an issue with their 2020 Jeep Compass Trailhawk has brought their car to the dealer for a problem with the auto start-stop (ASS) feature. The dealer suggests that the issue may be related to an electrical problem and recommends replacing the batteries for a hefty price of $600.

This recommendation leaves the car owner questioning if there might be another solution to the problem.

2. Multiple Instances Of Jump-Starting Required

The 2020 Jeep Compass Trailhawk continues to experience multiple instances where it requires a jump-start to get going. This frequent need for jump-starting is a cause for concern as it indicates a potential underlying issue with the car’s electrical system.

While the dealer’s recommendation of replacing the batteries was one attempt at resolving the problem, it seems that it may not be the solution after all.

3. Dash Error Message: ESC Coolant Too High

Adding to the list of issues with the car, the 2020 Jeep Compass Trailhawk displays an error message on the dashboard indicating that the ESC (Electronic Stability Control) coolant is too high. This error message further supports the hypothesis that there might be a larger electrical problem within the vehicle.

It is important to address this issue promptly as it could potentially compromise the safety and performance of the car.

4. Batteries Tested And Found Fine, But Issue Persists

Despite the dealer’s recommendation to replace the batteries, the car owner tests the batteries and finds that they are functioning properly. This discovery raises doubts about the accuracy of the dealer’s diagnosis.

If the batteries are not the source of the problem, then it becomes imperative to explore other potential causes for the malfunctioning auto start-stop feature.

5. Comparing Experience To 2016 Ford Fusion

The person discussing their issue with the 2020 Jeep Compass Trailhawk draws a comparison to their previous experience with a 2016 Ford Fusion. They imply that, given the Compass is a newer model, it should not be plagued with more significant problems.

This comparison serves as a reminder that while technology advances, it is essential to ensure that newer models are not encountering worse issues than their predecessors.

6. Author’s Experience With 2018 Altitude’s Auto Start-Stop Feature

The author of this discussion owns a 2018 Jeep Compass Altitude with an auto start-stop feature. The ASS feature on their vehicle used to work correctly but has recently stopped functioning.

This personal experience adds weight to the issue raised by the person with the 2020 Jeep Compass Trailhawk. If multiple Jeep Compass models are experiencing problems with the auto start-stop feature, it suggests that there may be an underlying defect or common issue that needs to be addressed by the manufacturer.

In conclusion, the person discussing the issue with the 2020 Jeep Compass Trailhawk and their comparison to the 2016 Ford Fusion highlights the need for proper troubleshooting and resolution of the auto start-stop feature problem. The dealer’s recommendation of replacing the batteries for $600 may not be the solution, especially if the batteries have tested fine.

The error message indicating high ESC coolant further suggests an electrical issue within the car. By sharing their experience with the 2018 Altitude’s auto start-stop feature, the author emphasizes the importance of investigating whether this problem affects multiple Jeep Compass models.

Whether it is a defect or a learning algorithm that needs adjustment, the manufacturer needs to address this issue promptly to provide a satisfactory solution for its customers.
