The defect
Custom Truck and Body Works (Custom Truck) is recalling certain 2020 F550 vehicles equipped with Weldon V-Mux Vista IV Standard LCD displays. These displays may experience low voltage spikes, and cause the LCD display to lock up or become nonfunctional, due to varying electrical installations.
The risk
If the LCD display becomes locked up or non-functional it can delay emergency efforts, which can increase the risk of injury.
