MOTOR COACH INDUSTRIES recall on D4000 ISTVD4500,D4505 and 1 more model

On certain vehicles, the steer angle sensor -- a component of the electronic stability control (ESC) system -- can fail. This could cause the ESC system to misinterpret data from the yaw rate sensor and the lateral accelerometer as a directional instability requiring intervention by brake activation of a selected wheel. This could occur during low speed turning manoeuvres. Unexpected brake application could result in a vehicle crash causing property damage, personal injury or death. Correction: Dealers will inspect and, if necessary, replace the steer angle sensor.
