2001-2018 Spartan Recall 18V350: Air Brake Valve Defect

RN
Reviewed by the RecallNotify editorial team
Published May 25, 2026

Recall 18V350 covers 309 2001-2018 Spartan Diamond, Advantage, Gladiator, and Metrostar vehicles for missing air-brake pressure protection valve. Repair is free at franchised Spartan dealers.

Spartan is recalling 309 2001-2018 Diamond, Advantage, Gladiator, and Metrostar emergency response vehicles because a missing pressure protection valve can let a disconnected air line drain air from the brake system. Loss of air braking increases crash risk, and Spartan dealers will install the valve free of charge.

What's wrong?

The 2001-2018 Spartan Diamond, Advantage, Gladiator, and Metrostar emergency response vehicles use air brakes, which rely on stored compressed air to apply braking force. The air reservoir holds that pressure for the brake system. A pressure protection valve is supposed to help preserve brake air when another air-operated system, such as the automatic lubrication controls, loses air.

On these vehicles, that valve was missing from the air circuit between the reservoir and the lubrication control module. If the air line at that point disconnects, air can escape from the reservoir side instead of being isolated. That loss of stored pressure reduces the air available to the brake system.

The warning sign is a low air warning in the cab. Treat that warning as a brake-system warning, not just a maintenance light, because it means the air supply for braking has dropped.

Who's affected?

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

What's the safety risk?

Loss of air to the air brake system increases crash risk because the brakes need air pressure to work correctly. If the cab shows a low air warning, pull over when it is safe, avoid further driving, and call a Spartan dealer for guidance. Repair is free at any franchised Spartan dealer.

What should I do?

  1. Check your VIN to confirm your 2001-2018 Spartan Diamond, Advantage, Gladiator, or Metrostar is included in this recall.
  2. Contact a franchised Spartan dealer to schedule the free inspection and pressure-protection-valve installation that protects air supply to the air brake system.
  3. Bring the recall notice if Spartan mailed one, or reference recall number 18V350 when you call.
  4. Drive cautiously until the repair, and take the vehicle out of service if the air brake system loses air.

What happens at the repair

At the dealer, a Spartan technician inspects the air brake plumbing for a pressure protection valve between the air reservoir and the lubrication control module. If the valve is missing, the technician installs one so a disconnected lubrication control module air line does not drain air from the brake system. The inspection and any valve installation are free under the recall. Spartan has a general reimbursement plan on file for owners who already paid for the same repair before the recall notice. Contact Spartan customer service with repair documentation to ask how the plan applies.

Frequently asked questions

What is recall 18V350?

Recall 18V350 covers 309 2001-2018 Spartan Diamond, Advantage, Gladiator, and Metrostar emergency response vehicles. The affected vehicles lack a pressure protection valve between the air reservoir and lubrication control module. If that air line disconnects, air brake pressure is lost, increasing crash risk.

What should I do if my 2001-2018 Spartan Diamond, Advantage, Gladiator, or Metrostar is on this recall?

Check your VIN to confirm your specific vehicle is included in recall 18V350. If it is, contact a franchised Spartan dealer or Spartan customer service at 1-800-543-5008. Ask for inspection and pressure protection valve installation under Spartan recall number 18017.

Is the recall repair free?

Yes. Federal recall law requires the manufacturer to repair the defect at no cost. Spartan dealers will inspect the vehicle and install a pressure protection valve, as needed, free of charge.

What is the safety risk in recall 18V350?

The safety risk is loss of air to the air brake system. NHTSA campaign 18V350 says a disconnected air line between the lubrication control module and air reservoir results in air loss to the brakes, increasing crash risk.

What if I bought my Spartan emergency vehicle used?

The free recall repair still applies. Recall eligibility follows the VIN, not the original owner. Check your VIN to confirm whether your specific Spartan Diamond, Advantage, Gladiator, or Metrostar is included, then reference recall 18V350 and Spartan recall number 18017 when you call for service.
