Osage Industries, Inc. (Osage) is recalling one 2021 Ford Super-Warrior III E450 vehicle equipped with a Weldon V-Mux Vista IV Standard LCD display used for controlling emergency vehicle lighting and HVAC functions. The display may experience low voltage spikes, and cause the LCD display to lock up or become nonfunctional, due to varying electrical installations.

A locked up or non-functional LCD display can delay emergency efforts, which can increase the risk of injury.
