10 recalls found in NHTSA data as of September 22, 2026

For the 2012 Kenworth T800. These apply to the model and year, not to one particular vehicle: check your VIN to see whether yours is included and whether it has been repaired.

Has your Kenworth been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Kenworth dealer can also check your VIN. Recall repairs are free.

Engine and engine cooling › Engine

Summary
PACCAR Incorporated (PACCAR) is recalling certain model year 2010-2016 Kenworth T440, T800, and W900 trucks manufactured August 31, 2009, to April 20, 2015, and 2008-2015 Peterbilt 320, 337, 348, 365, 382, and 384 trucks manufactured July 27, 2007, to April 28, 2015, and equipped with certain Cummins Westport ISL G engines. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.
Consequence

Service brakes, air › Supply › Check valve

Summary
Paccar is recalling certain model year 2012-2013 kenworth T170, T270, T370, T440, T470, T660, T700, T800, W900, and peterbilt 320, 330, 337, 348, 365, 367, 382, 384, 386, 388, 389, and 587 vehicles, manufactured from January 31, 2011, through January 19, 2012, and equipped with bendix atr-6 antilock traction relay valves. In extremely cold conditions, these bendix relay valves may potentially develop internal leakage. Internal leakage can lead to air pressure being delivered to affected primary or secondary brake causing continuous brake application.
Consequence
Unexpected continuous brake application can cause the brakes to overheat and lead to a fire. Unexpected continuous brake application can cause the driver to lose control of the vehicle, increasing the risk of a crash. Also, the brakes may be applied without illuminating the brake lights, failing to give proper warning to other drivers.
Remedy

Electrical system › Software

Summary
Paccar is recalling certain model year 2011-2012 kenworth T660, T700, and T800 vehicles manufactured from April 19, 2010, through may 13, 2011, and model year 2008, 2010, and 2011 peterbilt 365, 367, 384, 386, 387, 388 and 587 vehicles manufactured from April 20, 2010, through June 11, 2011, and equipped with paccar mx engines and eaton ultrashift dm or allison automatic transmissions (without auto-neutral). The fast idle control may be activated by the operator while the transmission is in gear.
Consequence

Service brakes, air › Slack adjusters

Summary
Paccar is recalling certain model year 2011-2012 kenworth T270/370, T440/T470, T800, T660, W900 and C500 vehicles manufactured between October 18, 2010, and January 28, 2011. Certain cast iron slack adjuster housings, which transmit braking force from the brake chamber push rod to the brake cam tube, may include a flow notch in the handle portion of the housing due to an error during the casting process. A flow notch in the handle portion may reduce the effective cross section structure and cause the slack adjuster housing to fracture.
Consequence
If the slack adjuster housing were to fracture, the wheel brake to which the slack adjuster housing is attached would no longer function, which could increase vehicle stopping distances, and if mounted on the steer axle, could cause the vehicle to pull to one side during braking, increasing the risk of a crash.
Remedy
Dealers will inspect and replace the slack adjuster housing as necessary. This service will be performed free of charge. The safety recall began on March 30, 2011. Owners may contact kenworth at 425-828-5440.
