What's wrong?
The Square D QO Plug-On Neutral Load Center on 2020-2021 Spartan Fire Metrostar and Gladiator fire trucks is the electrical panel that distributes power through circuit breakers. It also ties neutral conductors into the panel so current has a proper return path. When that connection is tight, the panel controls electrical loads and protects circuits as designed.
On the affected trucks, a neutral screw connection inside the load center is loose. A loose neutral connection adds resistance at the contact point, and resistance creates heat as current passes through. That heat can build inside the breaker box and cause the load center to overheat.
There is no warning sign before failure. Spartan Fire's filing does not identify a light, sound, smell, or driver-visible symptom that tells an owner the neutral connection has loosened before the panel overheats.

If the connection is loose or damaged, the technician repairs or replaces the neutral screw connection, free of charge under the recall. Spartan Fire points owners to Schneider Electric inspection, repair, or replacement through the normal warranty process. Out of pocket repairs already paid are handled through that warranty process, not through a separate reimbursement program. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
