Recall 18V094 covers 66 2013-2017 Freightliner fire-fighting vehicles for corroding pressure-relief-valve rings. Repair is free at any franchised Freightliner dealer.
Freightliner is recalling 66 2013-2017 M2, 4400, T370, Inferno, Cinder, Igniter, and Ember fire-fighting vehicles because Hale pressure relief valve rings in the water pumps can corrode and fail. That failure can open the valve and reduce water pressure for fire fighting, increasing the risk of injury; Freightliner dealers will complete the free repair.

What's wrong?
The Hale pressure relief valve assembly is part of the water pump system on 2013-2017 Freightliner M2, 4400, T370, Inferno, Cinder, Igniter, and Ember fire-fighting vehicles. Its job is to help control pump pressure so the water stream stays within the intended pressure range during fire fighting.
On affected vehicles, the retaining ring that secures the valve was plated steel instead of stainless steel. After repeated exposure to water, that ring can corrode early. If the ring fails, the pressure relief valve opens when it should stay secured, which reduces the water pressure available for fire fighting.
The warning sign is leakage at the relief valve assembly. If a crew sees water leaking from that area, the valve assembly needs inspection before the pump is relied on for service.

What's the safety risk?
A reduction in water pressure can hinder firefighting efforts and increase the risk of injury. Leakage at the relief valve assembly is the warning sign to watch for. If you see it, keep the apparatus out of fire response and call the dealer. Repair is free at any franchised Freightliner dealer.
What should I do?
- Check your VIN to confirm your 2013-2017 Freightliner M2, 4400, T370, Inferno, Cinder, Igniter, or Ember is included in this recall.
- Contact a franchised Freightliner dealer to schedule the free relief-valve retaining-ring replacement that helps preserve water-pump pressure for fire fighting.
- Bring the recall notice if you have it. If not, reference recall number 18V094 when you call.
- Call Freightliner customer service at 1-800-443-9006 if the dealer needs help confirming the repair path.
- Avoid using the vehicle for fire-fighting operations until the repair is complete; reduced water pressure can hinder fire fighting.
What happens at the repair
At the dealer, a Freightliner technician replaces the pressure relief valve retaining ring in the fire pump with a stainless steel retaining ring. The recall repair is free, and parts and labor are covered. The work addresses corrosion of the ring that secures the valve, which affects water pressure during fire fighting. A general reimbursement plan is on file for owners who already paid for this related repair before the recall. Keep your repair paperwork and contact customer service to ask how documented expenses are handled under that plan.

What should I do if my 2013-2017 Freightliner M2, 4400, T370, Inferno, Cinder, Igniter, or Ember is on this recall?
Check your VIN to confirm your specific fire-fighting vehicle is included in recall 18V094. If it is, contact a franchised Freightliner dealer or certified technician and reference recall number 18V094. The retaining ring replacement is free.
Is the recall repair free?

What is the safety risk in recall 18V094?
The safety risk is reduced water pressure during fire-fighting work. If the retaining ring corrodes and fails, the pressure relief valve can open, reducing water pressure available at the pump and hindering fire-fighting efforts, which increases injury risk.
