The defect
REV Ambulance Group Orlando, Inc. (REV) is recalling certain 2019-2021 Type I and IX vehicles equipped with Weldon V-Mux Vista IV LCD displays used for controlling emergency vehicle lighting and HVAC functions. These displays may experience low voltage spikes, causing the LCD display to lock up or become nonfunctional, due to varying electrical installations.
The risk
A locked up or non-functional LCD display can delay emergency efforts, which can increase the risk of injury.
The remedy
REV has notified owners, and Weldon, a division of Akron Brass will provide a replacement display, free of charge. Owner notification letters were mailed on May 5, 2021. Owners may contact REV customer servicer at 1-855-661-9232.
