2025 Jeep Compass Fuel Gauge Malfunction TSB

Symptoms of the Fuel Gauge Malfunction

Owners of certain 2025 Jeep Compass vehicles may encounter a frustrating issue related to their fuel system. The primary symptom reported is that after filling the fuel tank, especially when the "Low Fuel Light was on" prior to refueling, the fuel gauge does not accurately reflect the new fuel level. Compounding this, the "low fuel light is still on", falsely indicating that the vehicle is still low on fuel.

This discrepancy means that the instrument cluster's fuel gauge and warning light are not communicating the correct information to the driver. Such an inaccurate reading can lead to confusion, range anxiety, and potentially leave drivers stranded if they misjudge their actual fuel reserves. The 2025 Jeep Compass fuel gauge malfunction directly impacts the driver's ability to monitor their vehicle's fuel status reliably.

Diagnosis and Trigger Conditions

When technicians attempt to diagnose this fuel gauge malfunction, they may find no related diagnostic trouble codes (DTCs) stored in the vehicle's computer system. This absence of DTCs can make traditional troubleshooting challenging, as fault codes typically point directly to a failing component. The manufacturer's communication, GPOP - Issue Review System, advises a specific diagnostic approach to address this unique situation.

Technicians are instructed to compare the PCM fuel level sensor data on the WiTECH diagnostic tool with what is displayed on the vehicle's instrument cluster. WiTECH is a specialized diagnostic software used by dealerships to interface with vehicle control modules. A key indicator of this particular issue is when the PCM fuel percentage, as read by WiTECH, and the fuel gauge reading in the cluster do not match. This comparison helps to pinpoint whether the issue lies in the sensor's actual reading or the vehicle's interpretation and display of that data.

Important Warnings for Diagnosis and Repair

The manufacturer has issued a critical advisory regarding this issue. If the PCM fuel percentage and the fuel gauge do not match, do not replace the Fuel Pump Module (part number 68437981AS). This warning is crucial because replacing the MODULE, Fuel Pump/Level Unit will not resolve the underlying problem and would result in unnecessary repairs, labor costs, and parts expenses for the owner or dealership.

This instruction highlights that the issue is not a mechanical failure of the fuel pump or level sensor itself, but rather a communication or software-related discrepancy within the vehicle's systems. Engineering is actively aware of this issue and is working towards a resolution. Owners should be aware of this guidance to prevent misdiagnosis and incorrect part replacement, ensuring that any service performed is effective.

What Owners Should Do

If you own a 2025 Jeep Compass and experience the "Low Fuel Light" remaining on or an inaccurate fuel gauge after refueling, it is recommended to contact your authorized Jeep dealership. Clearly explain the symptoms you are experiencing, specifically mentioning that the fuel gauge does not show the correct fuel level and the low fuel light stays on, even after filling the tank.

While there is no immediate repair procedure outlined in the GPOP - Issue Review System document, the manufacturer's engineering team is actively working on a solution. Your dealership can document your concern, perform the recommended diagnostic comparison using WiTECH, and keep you informed about any future software updates or service bulletins that address this specific problem. It is important not to attempt to replace parts like the Fuel Pump Module, as this has been explicitly advised against by the manufacturer.
