What's wrong?
The pump shift solenoid on 2009-2021 Spartan Fire Gladiator and Metrostar emergency vehicles is an electrical valve that helps control the fire water pump system. When the vehicle is set up for pumping, the solenoid helps the pump control module receive the power it needs so the pump can shift and operate during a response.
On these vehicles, the solenoid is mounted inside the frame rail and was not specified with enough protection from water and road exposure. Internal corrosion can build up inside the solenoid. When that happens, power to the pump control module is lost, and the vehicle can fail to shift to pump mode.
There is no warning sign before failure. A crew can discover the problem only when the pump does not shift or the pump control module does not power up as expected.

The year and model narrow the recall, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
If the pump control module loses power, the fire pump can lose water pressure during firefighting, increasing the risk of injury. The solenoid can fail without warning, so crews should treat pump-pressure problems as a reason to stop operations and arrange service. Repair is free at any franchised Spartan Fire dealer.
What should I do?
- Check your VIN to confirm your 2009-2021 Spartan Fire Gladiator or Metrostar emergency vehicle is included in this recall.
- Contact a franchised Spartan Fire dealer to schedule the free fire water pump solenoid replacement that restores power to the pump control module.
- Bring the recall notice if Spartan Fire has mailed one, and reference recall number 21V329 when you call.
- Keep the vehicle available for service until the repair is complete, since solenoid corrosion can cut power to the pump control module and reduce water pressure for fighting fires.
What happens at the repair
At the dealer, a Spartan Fire technician replaces the suspect fire water pump solenoids that can corrode inside and cut power to the pump control module. The recall repair is free, and parts and labor are covered. Spartan Fire has a general reimbursement plan on file for this campaign. If you already paid for a related solenoid or pump-control repair, ask Spartan Fire customer service what documentation they need for reimbursement.

Frequently asked questions
What is recall 21V329?
Recall 21V329 covers 2,130 2009-2021 Spartan Fire Gladiator and Metrostar emergency vehicles with fire water pump solenoids that can corrode internally. That corrosion can cut power to the pump control module and cause loss of water pressure for fighting fires, which raises injury risk. Spartan Fire dealers replace suspect solenoids for free.
What should I do if my 2009-2021 Spartan Fire Gladiator or Metrostar is on this recall?
Check your VIN to confirm your specific emergency vehicle is included in recall 21V329. If it is, contact a franchised Spartan Fire dealer to schedule the solenoid replacement. Reference recall 21V329 when you call. Spartan Fire mailed owner letters on July 9, 2021.

Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and Spartan Fire dealers will replace suspect fire water pump solenoids free of charge. Owners can also contact Spartan Fire customer service at 1-517-543-6400 with recall 21V329 questions.
What is the safety risk?
The safety risk is loss of water pressure during fire response. Internal corrosion in the fire water pump solenoid can cut power to the pump control module, leaving the crew without the expected water pressure for fighting fires and raising the risk of injury.
