2021-2025 Jeep/RAM Diesel Fuel Filter Issues TSB 14-010-25

What is TSB 14-010-25?

Stellantis has released Technical Service Bulletin (TSB) 14-010-25 to address the frequent and sometimes premature replacement of fuel line components, particularly diesel fuel filters, in certain vehicles. This TSB aims to provide dealerships with a process to check for fuel system contamination before replacing components, reducing unnecessary repairs and warranty costs. This bulletin supersedes a previous version, TSB 14-010-25 dated May 16, 2025, and includes updated information on affected models, model years, and engine sales codes.

Symptoms of a Clogged Diesel Fuel Filter

Even before reaching the recommended service mileage, owners may notice several symptoms indicating that their diesel fuel filter is becoming clogged and requires earlier replacement. These symptoms suggest a potential issue with the Jeep RAM diesel fuel filter:

• Difficulty Starting the Engine: This can manifest as extended cranking times or a complete failure to start the engine.
• Sluggish Acceleration: Drivers might experience a noticeable lag or reduced responsiveness when pressing the accelerator pedal.
• Engine Stalling: The engine may unexpectedly shut down during operation.
• Poor Fuel Economy: A decrease in miles per gallon can occur without any changes in driving habits.
• Instrument Panel Cluster (IPC) Warnings: The vehicle's dashboard may display alerts such as "Fuel Filter Service Required" or "Water in Fuel" messages.

Important Warnings for Owners

If fuel system contamination is found to be the cause of your diesel fuel filter issues, it's important to note that Stellantis should not be charged for contaminated fuel. Dealerships are instructed to replace the contaminated fuel in the vehicle before proceeding with component repair or replacement. Additionally, technicians are advised to record the vehicle mileage every time a fuel filter is replaced.

Diagnosing Fuel System Issues

Before replacing any fuel line components, such as the diesel fuel filter, technicians are instructed to perform a check for fuel system contamination. This involves collecting a fuel sample to verify its condition. Fuel should appear clear and bright. If the sample is cloudy, hazy, or contains visible particulates or water droplets, it is considered contaminated. Addressing contaminated fuel first helps prevent recurring issues and reduces overall repair costs.

When to Replace the Fuel Filter

Dealerships are required to replace the diesel fuel filter under specific conditions to resolve the Jeep RAM diesel fuel filter problem:

• If catastrophic pump failure occurs, leading to the vehicle being towed to the dealership.
• If the last fuel filter replacement was performed more than 15,000 miles (24,140 km) ago.
• When the filter flow is restricted and contaminated with debris.
• If a leak is detected at the filter connection joints.
• In the presence of metal contamination at the fuel pump and throughout the fuel system.

Next Steps for Owners

If you are experiencing any of the symptoms listed above, especially the "Fuel Filter Service Required" or "Water in Fuel" warnings, it is recommended to contact your authorized Stellantis dealership. Inform them about the issues you are facing and mention TSB 14-010-25. The dealership will follow the diagnostic procedures outlined in the TSB to determine if fuel system contamination or a faulty diesel fuel filter is the cause and perform the necessary repairs.
