The short answer
NHTSA received PACCAR Incorporated’s report on Jan 25, 2013. Copied from NHTSA on Oct 20, 2026.
Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
An unexpected re-inflation of the suspension could result in personal injury to a person near the rear suspension.
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.

What the record doesn’t say
- NHTSA’s recall file doesn’t say whether anyone was hurt.
- Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
- This recall names only model years before 2015, which have no pages here. Your VIN, at NHTSA, says which recalls are open on a vehicle.
- How many have been returned or fixed isn’t in the notice.
