What's wrong?
The seat belt buckle on the 2014-2015 Ic Bus Ce and Recb is the latch point that holds the belt's metal latch plate in place. During normal use, the latch plate locks into the buckle when the passenger belts in. Pressing the release button should fully separate the latch plate from the buckle so the belt opens right away.
On affected buses, the IMMI-brand L9 buckle does not always release cleanly. When the release button is pressed, the latch plate can stay partly caught inside the buckle instead of coming free. The problem is in the buckle and latch interaction, which leaves the belt difficult to unlatch and means the seat belt assembly does not meet the seat belt standard cited in the recall.
There is no warning sign before failure. The issue shows up when someone tries to release the belt and the latch plate does not come free cleanly.
Who's affected?
Covers Ce buses from 2014 and 2015 plus 2014 Recb buses, all tied to the seat belt component.

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 buckle latch plate that stays partly engaged after the release button is pressed can slow exit from the vehicle during an emergency. That raises injury risk when passengers need to get out quickly. If the buckle does not release cleanly, keep the bus out of service until a dealer checks it. Repair will be free at any franchised Ic Bus dealer once available.
What should I do?
- Check your VIN to confirm your 2014-2015 Ic Bus Ce or Recb bus is included in this recall.
- Use the Ic Bus owner notice mailed in 2014 if you have it. If not, reference recall number 13V631 when you call.
- Contact Ic Bus customer service at 1-800-448-7825 with questions about the seat belt buckle inspection.
- Ask a franchised Ic Bus dealer about the seat belt buckle inspection and replacement that fixes the difficult-to-unlatch buckle.
- Bring the bus in only after the dealer confirms recall service instructions and parts for your VIN.
What happens at the repair
At the dealer, an Ic Bus technician inspects the IMMI L9 seat belt buckles. Any buckle that does not release correctly is replaced under the recall. Parts and labor are covered once the dealer repair is available. Navistar expected owner notifications to begin by February 18, 2014, and listed campaign number 13521 for dealer reference. If the bus is still unrepaired, give the service desk the VIN and campaign number so they can confirm parts and repair handling.
