Recall 13V630 affects 2,357 2014-2015 Ic Bus Casb, Resb, Be, and Ae school buses for binding seat belt buckles. Repair is free.
Ic Bus is recalling 2,357 2014-2015 Casb, Resb, Be, and Ae school buses because IMMI-brand L9 seat belt buckles can leave the latch plate partly engaged after the release button is pressed. A buckle that stays partly latched can slow exit from the bus and increase injury risk in an emergency, and Ic Bus dealers will complete the repair free once available.

What's wrong?
The seat belt buckle on affected 2014-2015 Ic Bus Casb, Resb, Be, and Ae school buses is the latch point for the belt's metal tongue. On buses equipped with IMMI L9 buckles, the buckle is supposed to hold the belt during a ride, then release the latch plate cleanly when the button is pressed.
When the release button is pressed on these buckles, the latch plate can stay partly caught inside the buckle instead of coming free. That leaves the seat belt difficult to unlatch, even though the person has pressed the release button. The defect is in the buckle and latch engagement, so the belt can hold but fail to release cleanly.
There is no warning sign before failure. The problem shows up when a buckled passenger presses the release button and the belt does not unlatch normally.
Who's affected?
Covers Casb, Resb, Be, and Ae buses across the 2014 and 2015 model years, all tied to the seat belt component.

What's the safety risk?
When the buckle latch plate stays partly engaged after the release button is pressed, getting out of the vehicle is harder, raising injury risk during an emergency. Check each belt release before putting the bus back in service and schedule the recall work soon. Repair will be free at any franchised Ic Bus dealer once available.

- Ask the dealer to inspect and replace the seat-belt buckles that stay partly latched after the release button is pressed.
- Reference recall number 13V630 and Ic Bus campaign numbers 13519 and 13520 when you call.

What happens at the repair
At the dealer, an Ic Bus technician inspects the IMMI brand L9 seat belt buckles and replaces any buckle that does not release correctly. The source remedy says Navistar began owner notices on February 26, 2014, and the inspection and buckle replacement are free under the recall. Confirm current repair availability with the Ic Bus dealer before arranging service. Once available for your VIN, parts and labor are covered.
