NHTSA campaign 13V027000
Hazard
PACCAR is recalling certain model year 2013 Kenworth T680 vehicles, manufactured from November 29, 2012, through December 6, 2012; and model year 2013 Peterbilt 579 and 567 vehicles, manufactured from August 28, 2012, through December 31, 2012. These vehicles were equipped with the air suspension dump valve option. New software may cause the rear air suspension to re-inflate without warning when the operator turns the ignition key to the "off" position.
Consequence
An unexpected re-inflation of the suspension could result in personal injury to a person near the rear suspension.
Remedy
PACCAR will notify owners, and dealers will reprogram the software. The recall will begin during February 2013. Owners may contact Kenworth at 1-425-828-5000 or Peterbilt at 1-940-591-4000.
