Nova Bus is recalling 339 2020-2023 Lfs transit buses because affected electric power steering systems lack a check valve that keeps hydraulic pressure from moving the steering wheel without the driver's input. An unintended steering movement increases the risk of a crash or injury, and Nova Bus dealers will complete the recall repair free of charge.

What's wrong?
The electric power steering system on 2020-2023 Nova Bus Lfs transit buses uses an electric motor, identified as MOTOR EHS-150 G2 24V, to help the driver turn the steering wheel. The system adds hydraulic steering assist so the driver does not have to supply all steering force by hand, especially at low speed or during tight maneuvers.
On affected buses, the steering system was built without a check valve. That valve is supposed to block hydraulic pressure from returning into the steering system in the wrong direction. Without it, pressure inside the system can act on the steering gear and turn the steering wheel without the driver's input. Nova Bus traced the issue to an integration problem that did not account for all extreme operating conditions.
There is no warning sign before failure. The driver would not get a prior symptom from the steering system before the wheel moves unexpectedly.
Who's affected?
