2013-2017 Freightliner Cascadia Recall 16V656: PDM Short

Recall 16V656 affects 1,039 2013-2017 Freightliner Cascadia trucks with CNG engines for a PDM short-circuit fire risk. Repair is free at any franchised Freightliner dealer.

Freightliner is recalling 1,039 2013-2017 Cascadia trucks with compressed natural gas engines because the Power Distribution Module sits near the CNG fuel tank, where road water and contaminants can reach it. If the module short circuits, the fire risk increases, and Freightliner dealers will complete the repair free of charge.

What's wrong?

The power distribution module on 2013-2017 Freightliner Cascadia trucks with compressed natural gas engines is an electrical junction point. It routes battery power to truck systems through protected circuits, much like a central fuse and relay box. On these trucks, that module is mounted near the CNG fuel tank, which stores compressed natural gas for the engine.

The problem is the module's location. Road water, salt, dirt, and other contaminants hit the PDM as the truck operates. When that material gets into or around the electrical module, it creates a path for an electrical short. Freightliner investigated reports of PDMs melting or burning in that area, then recalled the affected trucks.

There is no warning sign before failure. If the PDM shorts, the issue starts inside the electrical distribution area, so the driver is not given a reliable symptom before the module overheats or fails.

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

What's the safety risk?

A short circuit in the PDM increases the risk of fire, especially if the nearby CNG tank leaks. No warning sign is listed, so treat this as a prompt repair issue if your VIN is included. Schedule service with a franchised Freightliner dealer. Repair is free at any franchised Freightliner dealer.

What should I do?

  1. Check your VIN to confirm your 2013-2017 Freightliner Cascadia is included in this recall.
  2. Contact a franchised Freightliner dealer to schedule the free PDM relocation, which moves the module away from road water and contaminants near the CNG fuel tank.
  3. Bring the recall notice if you have it. If not, reference recall number 16V656 when you call.
  4. Tell the dealer before the appointment if the truck has a CNG fuel leak or electrical short concern.

What happens at the repair

At the dealer, a Freightliner technician relocates the Power Distribution Module away from the compressed natural gas fuel tank area, where road water and contaminants can reach it. The work is meant to reduce the chance of water intrusion and an electrical short at the module. Parts and labor are covered by the recall at a Freightliner authorized service facility.
