What's wrong?
The rear air suspension on affected 2013 Kenworth T680, 567, and 579 trucks uses air bags to support the back of the truck and control ride height. The air suspension dump valve lets the operator release air from that system when the truck needs to sit lower, such as during loading or unloading. Software tells that valve when to dump air and when to let the rear suspension fill again.
On trucks equipped with the air suspension dump valve option, the new software can command the rear suspension to re-inflate when the operator turns the ignition key to the off position. That means the back of the truck can rise after the operator has shut it down. The issue is in the control logic, not in a broken air bag or spring.
There is no warning sign before failure. The rear suspension can re-inflate without warning when the ignition is turned off.

What's the safety risk?
Unexpected re-inflation of the rear suspension creates an injury risk for anyone standing near that area.

What should I do?
- Check your VIN to confirm your 2013 Kenworth T680, 567, or 579 is included in this recall.
- Wait for Kenworth's owner notice if the software reprogramming is not open for your VIN.
- Contact a franchised Kenworth dealer and ask about the free software reprogramming that keeps the rear air suspension from re-inflating without warning.
- Bring the recall notice if Kenworth has mailed one. If not, reference recall number 13V027 when you call.
- Keep people clear of the rear suspension when turning the ignition off until the repair is complete.
What happens at the repair
At the dealer, a Kenworth technician reprograms the vehicle software tied to the air suspension dump valve option. PACCAR's filing says the software update is the recall remedy. Because the remedy status is not listed as available in the source data, confirm the repair path before making a service trip. The dealer repair will be free once available, with parts and labor covered under the recall.
