What's wrong?
The Weldon V-Mux Vista IV Flat Panel in these 2020 Spartan Fire Gladiator and Metrostar vehicles is the LCD control screen tied into the instrument panel. It controls emergency vehicle lighting and HVAC functions, meaning heat, ventilation, and air conditioning. In normal use, the screen receives vehicle power and keeps those body-control functions available to the operator.
On affected vehicles, the display is more sensitive to negative low-voltage spikes from the vehicle's electrical installation. The unit is supposed to restart after a voltage disturbance, but this version does not always restart successfully. When that happens, the LCD screen can lock up or stop working instead of returning to normal operation.
There is no warning sign before failure. The display can lock up or go blank while the vehicle is in use, so the problem can appear as a sudden loss of the control screen.
Who's affected?
Both listed models share the same Weldon V-Mux Vista IV flat-panel instrument system.

A matching year and model does not confirm inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
If the LCD display locks up or stops working, emergency crews can lose time during response. That delay increases the risk of injury. There is no warning sign before the display failure, so schedule the repair soon. Repair is free at any franchised Spartan Fire dealer.
What should I do?
- Check your VIN to confirm your 2020 Spartan Fire Gladiator or Metrostar is included in this recall.
- Contact a franchised Spartan Fire dealer to schedule the free IV Standard LCD display replacement that fixes the emergency-lighting and HVAC display lockup.
- Bring the recall notice if Marion Body Works sent one, and reference recall number 20V812 when you call.
- Limit emergency use if the LCD display locks up or stops working, and contact the dealer before returning the vehicle to service.
What happens at the repair
At the dealer, a Spartan Fire technician replaces the IV Standard LCD displays with updated Vista IV display units that are less sensitive to voltage drop. The replacement parts and labor are free under the recall. Before the appointment, cycling vehicle power can reset a locked display and restore normal operation, either through a power reset button when equipped or by restarting the vehicle. The dealer repair is the permanent recall remedy.
