What's wrong?
The seat belt buckle on the 2014 Thomas Mybus is the latch point that holds the belt closed across the occupant. The latch plate clicks into the buckle during use, and the release button is supposed to let that latch plate come free when the ride is over.
On affected buses, the IMMI-brand L9 buckle does not always release cleanly. When the button is pressed, the latch plate can stay partly caught in the buckle instead of clearing it. That partial engagement makes the belt difficult to unlatch, which is why the recall says the buses do not meet the federal seat belt assembly standard.
There is no warning sign before failure. The problem shows up when someone presses the release button and the belt does not come loose as expected.

What's the safety risk?
A seat belt buckle that stays partly latched after the button is pressed can slow exit from the vehicle. In an emergency, delayed egress increases the risk of injury. If the buckle sticks or does not release cleanly, stop using that seating position and arrange service. Repair will be free at any franchised Thomas dealer once available.

- Use extra care with passengers until the repair is complete, and make sure each buckle latches and releases before travel.
What happens at the repair
The dealer repair is to address the IMMI L9 seat belt buckle that can keep the latch plate partly caught after the release button is pressed. Once the repair is available for your VIN, a Thomas technician replaces the affected buckle when needed, free of charge. The goal is to restore normal seat belt release so the buckle unlatches cleanly. Parts and labor are covered under the recall.
