What's wrong?
The front steer axle on the 2012 Ic Bus Iccb and Durastar supports the front wheels and gives the steering system a fixed point to work from. These trucks and buses used a Meritor MFS08 Series non-drive front steer axle. Steering attachment bolts fasten key steering hardware to that axle, so the wheels respond correctly when the driver turns the wheel.
On the recalled trucks and buses, those steering attachment bolts were not tightened enough during assembly. A bolt that starts below the correct torque can loosen further as the vehicle is driven. That leaves the steering connection less secure than designed and puts extra movement into a part that is supposed to stay fixed.
There is no warning sign before failure. An owner cannot confirm bolt torque by pedal feel, sound, or a dashboard light, so the repair inspection is what determines whether the steering attachment is secure.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
Under-torqued steering arm bolts can fatigue, fracture, or let the arm separate. That can cause loss of steering control and increase the risk of a crash. If your VIN is included, schedule the recall repair soon and drive cautiously until the dealer completes it. Repair will be free at any franchised Ic Bus dealer once available.

- Contact a franchised Ic Bus dealer and ask about the free steering-attachment-bolt repair for the Meritor front steer axle.
- Reference recall number 11V589 when you call, and bring the recall notice if Ic Bus mailed one.
- Drive cautiously until the repair is complete, and stop driving if the steering feels loose or abnormal.
