Recall 21V330 covers 266 2017-2020 Eldorado Xhf, Ezrm, and Axess vehicles for a fuel-rail leak. Free repair at franchised Eldorado dealers once available.

Eldorado is recalling 266 2017-2020 Xhf, Ezrm, and Axess vehicles because a sealing washer can fail to seat correctly in pilot bore holes, allowing the high pressure fuel rail assembly to leak. A fuel leak near an ignition source increases fire risk; the dealer repair will be free once available.

What's wrong?

The high pressure fuel rail on 2017-2020 Eldorado Xhf, Ezrm, and Axess buses is part of the Cummins L9 diesel fuel injection system. It holds diesel fuel under high pressure and sends it to the injectors, which meter fuel into the engine for combustion. The rail depends on sealed end joints to keep fuel contained while the engine is running.

On affected buses, the rail end sealing bores were built with pilot bores that are too small for the sealing washer. That washer is supposed to sit flat and help clamp the joint closed. When it does not seat correctly, the joint lacks the load needed to stay sealed in service, and the high pressure fuel rail assembly can leak diesel fuel.

What an operator notices is practical and sensory. Diesel fuel can be visible near the engine or noticeable by smell, and the check engine lamp can illuminate.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.

What's the safety risk?

A fuel leak near an ignition source increases the risk of a fire. If the operator sees or smells diesel fuel, or the check engine lamp turns on, stop using the vehicle and call the dealer. Repair will be free at any franchised Eldorado dealer once available.

What should I do?

  1. Check your VIN to confirm your 2017-2020 Eldorado Xhf, Ezrm, or Axess is included in this recall.

  3. Reference recall number 21V330 when you call or schedule service.
  4. Ask a franchised Eldorado dealer about the free fuel-rail inspection and replacement that fixes the leak at the high pressure fuel rail assembly.
  5. Avoid parking near ignition sources and stop driving if you smell fuel or see a fuel leak before the repair is complete.

What happens at the repair

Once Eldorado opens the final dealer repair, an Eldorado technician will inspect the high pressure fuel rail assembly and replace the rail as necessary. Parts and labor are free under the recall. Eldorado has a general reimbursement plan on file for related repairs paid before the recall notice.
