2019–2024 Rev Ambulance Type I, Rev Ambulance Type IX, Rev Ambulance Type Iii: Electrical System recall

What's wrong

REV Ambulance Group Orlando, Inc. (REV) is recalling certain 2019-2024 Type I, Type III, and Type IX vehicles equipped with certain Weldon Vmux HC1.7 Input/Output multiplex nodes. In the event of a short circuit or wiring failure, the firmware in the node may fail to shut off the output pin, resulting in overloaded electrical circuits.

Why it matters

Overloaded electrical circuits can overheat, increasing the risk of fire.

The fix

Dealers will update the firmware, free of charge. Owner notification letters were May 17, 2024. Owners may contact REV customer service at 1-855-661-9232.

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
