What is wrong

Nova Bus (US) Inc. (Nova) is recalling certain 2021 LFS buses. The vehicle multiplex software may unexpectedly cause the door system electronic control module (ECM) to open and close the rear passenger door when the bus stops.

What can happen

A passenger may exit the bus in an unsafe location if the rear passenger door opens unexpectedly, increasing the risk of injury. Additionally, the doors may unexpectedly close on an exiting passenger, increasing the risk of injury.

The remedy

Nova Bus will provide instructions for how to update the vehicle multiplex and door system ECM software, and install a hardware dedicated wire kit, free of charge. Owner notification letters were mailed December 15, 2021. Owners may contact Nova customer service at 1-800-350-6682. Nova's number for this recall is CR5220/5221/5222.

Notes

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.
