What's wrong?
The air governor in the 2011 Kenworth T270, T370, and T800 is part of the truck's air brake system. It monitors air pressure and controls when the compressor builds pressure for the brake system. The emergency spring brakes depend on that pressure signal so they apply at the right time when air pressure drops.
On affected trucks, the DV-2 air governor was assembled with a blank plug where a breather should have been installed. That breather is needed so the governor can respond correctly to pressure changes. Without it, the governor does not reliably detect a loss of air pressure during normal use, and the emergency spring brakes can come on slowly instead of as designed.
There is no warning sign before failure. A driver should not count on a light, sound, or brake feel change to show that the air governor has this assembly problem.
Who's affected?
The T270, T370, and T800 are tied to the same air brake system, so the component issue is the same across the listed trucks.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific truck.
What's the safety risk?
Low air pressure warnings mean the air system needs attention. If the audible or visual alarm activates, stop in a safe place and contact the dealer; ignoring the warning leaves the vehicle at risk of a crash or fire. Repair will be free at any franchised Kenworth dealer once available.

- Bring the owner notice if you have it. If not, reference recall number 10V211 when you call.
