## What is wrong

Nova Bus \(Nova\) is recalling certain 2016 LFS and LFS Artic buses equipped with specific Allison Transmission drive units.  The pressure switches on these Drive Units may fail, possibly resulting in a loss of drive.


## What can happen

A loss of drive can disable the vehicle unexpectedly, increasing the risk of a crash.  Additionally, offloading passengers to transfer them to another bus can increase the risk of injury.


## The remedy

Nova will notify owners, and Allison Transmissions will replace the C1 and C2 pressure switches, free of charge.  The recall began September 15, 2020.  Owners may contact Nova customer service at 1\-800\-350\-6682.  Nova's number for this recall is CR4943.
