What's wrong?
The driver's seat in the 2009-2010 Mci D4505 and D4005 motor coaches uses a Stabilus Bloc-O-Lift shock damper as part of the National Seating Company seat assembly. That damper helps hold the driver's seat at the selected height and controls the seat's movement, so the driver stays in a stable position while steering, braking, and reaching the pedals.
In recall 10V409, the seat shock damper can break. When that happens, the seat is no longer supported the way it was designed to be supported. The driver's seat can drop to the floor suddenly, which can pull the driver out of the expected seating position and make the coach harder to control.
There is no warning sign before failure. The filing says the seat can drop without warning, so an owner or fleet operator should treat an unexpected change in seat height as a defect that needs dealer attention.
Who's affected?
D4505 and D4005 buses span the 2009-2010 model years, all tied to the seat assembly.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
A failed seat shock while the bus is in operation can make the driver lose control and crash. Schedule the recall repair before putting the bus back into regular service, and call service if the driver seat feels unstable. Repair will be free at any franchised Mci dealer once available.
What should I do?
- Check your VIN to confirm your 2009-2010 Mci D4505 or D4005 is included in this recall.
- Contact Mci customer service at 1-800-241-2947 for current repair instructions and dealer scheduling.
- Bring the recall notice if Mci mailed one. If not, reference recall number 10V409 when you call.
- Schedule the free seat-shock replacement that fixes the driver's seat drop risk.
- Avoid operating the coach if the driver's seat drops or will not stay in position.
What happens at the repair
Mci notified owners beginning September 15, 2010. At the dealer, the Mci technician inspects the National Seating driver seat assembly and replaces the seat shock when the shock damper is covered by the recall. The work addresses a seat shock that can break and let the driver seat drop without warning. The dealer repair is free under the recall, including parts and labor. If the coach still has the original affected seat shock, ask the service desk to confirm the recall repair was completed before returning it to service.
