The air tanks have an insufficient volume of air for the brake system.

RiskInsufficient air volume can reduce braking performance and increase the risk of a crash.

FixDealers will install the correct volume air tanks, free of charge. Owner notification letters were mailed August 12, 2024. Additional owner notification letters were mailed October 27, 2025. Owners may contact PACCAR customer service at 1-425-828-5888. PACCAR's number for this recall is 24KWD.

PACCAR Incorporated (PACCAR) is recalling certain 2008-2019 Peterbilt 330, 335, 337, 340, 348, 365, 367, 384, 386, 387, 388, 389, 567, 579 and 587 vehicles and 2008-2020 Kenworth T170, T270, T370, T660, T680, T800, T880, and W900 vehicles equipped with NAMUX Software. In the event that the Anti-lock Brake System (ABS) loses battery and/or ignition power to the controller, the dash warning light for the ABS may not illuminate to warn the driver of the loss of ABS.

The recall began May 26, 2020. Owners may contact Kenworth customer service at 1-425-828-5888 or Peterbilt customer service at 1-940-591-4220. PACCAR's number for this recall is 20pbc AND 20KWB.

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.

RiskIf engine oil comes into contact with a hot surface, there is an increased risk of a fire.

FixCummins will notify owners on behalf of PACCAR, and Cummins service centers will administer the repairs which include securing the ends of the 90-degree elbow and reprogramming the electronic control module (ECM) with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact Kenworth customer service at 1-425-828-5000, Peterbilt customer service at 1-940-591-4000 or Cummins Inc. at 1-800-343-7357. PACCAR's number for this recall is 15KWH and 515-G.

PACCAR is recalling certain model year 2007-2014 Kenworth T800 and W900 trucks manufactured March 22, 2006, through July 15, 2013 and equipped with Primaax tridem rear suspensions and a pusher and/or tag axle. The affected trucks have brake chambers that take longer to apply or release the brakes than the required time limit. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."

RiskBrakes that take longer to apply may lengthen the distance needed to stop the truck, increasing the risk of a crash.

FixPACCAR will notify owners, and dealers will modify the air brake system, free of charge. The recall began on January 15, 2014. Owners may contact PACCAR at 1-425-468-7400. Kenworth's recall number is 13KWL.

PACCAR IS RECALLING CERTAIN MODEL YEAR 2008-2012 KENWORTH T2000, T660, T700, T800, AND W900, AS WELL AS MODEL YEAR 2009-2012 PETERBILT 365, 367, 384, 386, 387, 388, 389, AND 587 TRUCKS EQUIPPED WITH PACCAR MX ENGINES. THE OIL MODULE CENTRIFUGAL SPINNER FILTER CAP IN THE PACCAR MX ENGINE MAY BECOME LOOSE, POSSIBLY ALLOWING THE CAP TO COME OFF AND ENGINE OIL TO PARTIALLY DISCHARGE FROM THE OIL MODULE ONTO EXHAUST COMPONENTS.

RiskTHE DISCHARGE OF ENGINE OIL ONTO EXHAUST COMPONENTS WHICH ARE HOT, SUCH AS WHEN THE ENGINE IS UNDER SIGNIFICANT LOAD, MAY CAUSE A FIRE.

FixDEALERS WILL RE-TORQUE THE OIL MODULE FILTER CAP AND INSTALL A SECONDARY RETENTION DEVICE ON THE SECONDARY CENTRIFUGAL SPINNER FILTER CAP. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN DURING MARCH 2011. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440 AND PETERBILT AT 1-940-591-4196.

THE AIR DISC BRAKE CALIPER COULD BE INSTALLED ON THE WRONG SIDE OF THE DRIVE AXLE POTENTIALLY CAUSING INTERFERENCE WITH THE SUSPENSION BRACKET AND THE REAR SUSPENSION AS THE OUTERMOST BRAKE PADS WEAR AND THE FLOATING CALIPER MOVES INBOARD.

RiskAS THIS INTERFERENCE GETS LARGER, THIS COULD EVENTUALLY LEAD TO REDUCED BRAKING PERFORMANCE, INCREASING THE RISK OF A CRASH.

FixDEALERS WILL VERIFY THE CORRECT ORIENTATION OF THE BRAKE CALIPER AND PERFORM THE NECESSARY REPAIR FREE OF CHARGE. THE SAFETY RECALL BEGAN ON NOVEMBER 24, 2010. OWNERS MAY CONTACT KENWORTH AT 425-828-5440.

PACCAR IS RECALLING CERTAIN MODEL YEAR 2008-2010 TRUCKS EQUIPPED WITH TRW STEERING SHAFTS. THE CIRCUMFERENTIAL WELD AROUND THE STEERING SHAFT TUBE THAT WELDS THE SPLINED TUBE TO THE NON-SPLINED TUBE MAY BE MISLOCATED. MISLOCATION OF THE CIRCUMFERENTIAL WELD MAY ALLOW THE SPLINED TUBE AND NON-SPLINED TUBE TO ROTATE RELATIVE TO ONE ANOTHER DURING A LOW SPEED, HIGH TORQUE TURN, POSSIBLY RESULTING IN A SEPARATION OF THE TWO TUBES.

RiskA SEPARATION OF THE SPLINED AND NON-SPLINED TUBES WOULD CAUSE A LOSS OF STEERING CONTROL AND INCREASE THE RISK OF A VEHICLE CRASH.

FixDEALERS WILL INSPECT THE STEERING SHAFT USING A WELD PLACEMENT GAUGE PROVIDED BY TRW. ANY STEERING SHAFT FOUND TO HAVE BEEN WELDED IMPROPERLY WILL BE REPLACED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON JULY 30, 2010. OWNERS MAY CONTACT KENWORTH AT 425-828-5440 AND PETERBILT AT 940-591-4196.
