Paccar is also is recalling 10.414 model year 2014 Kenworth T660, T680, T700,T800, T880, W900, T440, T470, T370, T270, T170, C500, and C550 chassis manufactured between Aug. 7, 2013 and Oct. 31, 2013, and Peterbilt 320, 325, 330, 337, 348, 365, 367, 382, 384, 386, 388, 389, and 587 chassis manufactured between Aug. 7, 2013 and Nov. 3, 2013, and equipped with IMMI-brand L9 seat belt buckles.

When the button is pressed to release the seat belt, the latch plate can become partially engaged with the buckle, making the seat belt difficult to unlatch, resulting in these vehicles failing to conform to the requirements of Federal Motor Vehicle Safety Standard No. 209, "Seat Belt Assemblies."If the latch plate remains partially engaged after the button is pressed, egress from the vehicle could be hindered which would increase the risk of injury in the event of an emergency.

Paccar will notify owners, and dealers will inspect and replace the seat belt buckles, as necessary, free of charge. The recall is expected to begin by the end of February 2014.

Kenworth's number for this campaign is 14KWC. Peterbilt's number for this campaign is 114-B.

Owners of any of the vehicles for either recall may contact Paccar at 1-425-468-7400 or the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236.
