Fatal crashes in the US
From 2020 to 2023, 96 T600 vehicles were involved in crashes on US public roads in which someone died, and 13 people died inside them. These are counts, not crash rates: a model with more cars on the road shows up more often, and people killed outside the vehicle are not counted here.

Recalls
53 campaigns cover the T600; the latest 12 are below.
PACCAR Incorporated (PACCAR) is recalling certain 2017-2019 Kenworth C500, T600, T660, T680, T800, T880 and W900 trucks, as well as Peterbilt 367, 386, 389, 567, 579 and 587 trucks, equipped with Cummins ISX15 or X15 diesel engines. In certain driving conditions, such as on a long down-hill grade, the fuel line may burst if the fuel pump cooling circuit screen becomes restricted.
Paccar is recalling certain model year 2013 kenworth T400, T600, T700, T800, and W900 vehicles, manufactured from July 18, 2012, through August 10, 2012. Cap screws securing the main driveline to the forward rear axle and cap screws on the inter-axle driveline may not have been properly torqued.
PACCAR IS RECALLING CERTAIN MODEL YEAR 2007-2011 KENWORTH C500, T2000, T600, AND T660, AS WELL AS MODEL YEAR 2009-2011 PETERBILT 387 AND 388 TRUCKS EQUIPPED WITH CATERPILLAR C15 ENGINE AND MANUFACTURED FROM MAY 11, 2006, THROUGH SEPTEMBER 17, 2010. DEGRADATION OF A COMBUSTION TUBE WELD CAN CAUSE RADIAL HEAT IMPINGEMENT ON THE BODY WHICH MAY BURN THROUGH CERTAIN BODIES USED ON C15 ENGINES.
PACCAR IS RECALLING CERTAIN MODEL YEAR 2007-2008 KENWORTH AND PETERBILT VEHICLES MANUFACTURED FROM FEBRUARY 2, 2006 THROUGH APRIL 30, 2007. THE BEARING SURFACES OF THE EXTENDED LUBE UNIVERSAL JOINT THAT ATTACHES THE INTER-AXLE DRIVELINE TO THE DRIVE AXLE MAY BECOME PREMATURELY WORN DUE TO BREAKDOWN OF LUBRICATION AND/OR EXCESSIVE HEAT. PREMATURELY WORN BEARING SURFACES MAY RESULT IN THE U-JOINT BECOMING LOOSE AND/OR BINDING. THIS CONDITION MAY RESULT IN UNIVERSAL JOINT FAILURE, ALLOWING THE INTER-AXLE DRIVELINE TO DETACH FROM THE AXLE.
KENWORTH IS RECALLING 3,423 MY 2004-2009 T2000, T800,T600, W900 AND T660 VEHICLES. INCREASED BRAKE EXCITATION IN A CERTAIN VEHICLE CONFIGURATION WHICH INCLUDES BENDIX DRUM BRAKES, WIDE BASE LOW PROFILE SINGLE TIRES, AND AN AG400 OR AG460 REAR SUSPENSION, DUE TO ITS UNIQUE BRAKE CLOCKING AND CAM TUBE LENGTH, CAN CAUSE FATIGUE AND CRACKING TO BRAKE ASSEMBLY COMPONENTS.
PACCAR IS RECALLING 130 MY 2004-2009 T2000, T800, T600, W900 AND T660 KENWORTH TRUCKS BUILT WITH AN AG400 REAR SUSPENSION, LONG STROKE BRAKE CHAMBERS, AND WIDE BASE TIRES (SUPER SINGLES). THESE VEHICLES MAY DEVELOP AN INCREASE IN LATERAL AND VERTICAL AXLE MOVEMENT. THIS MOVEMENT MAY CAUSE PART OR PARTS OF THE BRAKE ASSEMBLY (BRAKE CAM TUBE SUPPORT, BRAKE CHAMBER BRACKET, BRAKE CHAMBER, BRAKE SPIDER) TO DEVELOP FATIGUE CRACKS, POSSIBLY RESULTING IN THE FAILURE OF THE PART OR PARTS WITHIN THE BRAKE ASSEMBLY.
PACCAR IS RECALLING 4,883 MY 2006-2009 KENWORTH T600, T660, T800, W900, T2000 AND MY 2008-2009 PETERBILT 365, 367, 379, 384, 386, 387, 388 AND 389 TRUCKS. INADEQUATE STIFFNESS OF THE DIESEL PARTICULATE FILTER (DPF) BRACKET COULD RESULT IN SEPARATION OF THE DPF FROM THE CHASSIS.
KENWORTH IS RECALLING 1,189 MY 2009 T2000, T600, T660, T800 AND W900 TRUCKS. THE AXLE U-BOLTS ATTACHING THE AXLE TO THE DRIVE BEAM ON CERTAIN AG380 REAR SUSPENSIONS MAY HAVE RECEIVED INSUFFICIENT FASTENER TORQUE DURING THE INSTALLATION PROCESS.
PACCAR IS RECALLING 3,573 MY 2007 KENWORTH C500, T800, T600, T2000, AND W900 CHASSIS BUILT WITH PHILLIPS QCS II TRAILER CABLE CONNECTION AND TRAILER CABLE MOUNTING BRACKET WITH 'U-SHAPED' CUT OUT. CERTAIN TRAILER CABLE MOUNTING BRACKETS HAVE A 'U-SHAPED' CUT OUT THAT ONLY PARTIALLY SUPPORTS THE TRAILER CABLE CONNECTION. PARTIAL SUPPORT OF THE CABLE CONNECTION MAY ALLOW THE MOLDED BOOT AND ELECTRICAL GROUND PIN TO PARTIALLY OR COMPLETELY PULL AWAY FROM THE 7-WAY SOCKET. PARTIAL OR COMPLETE DETACHMENT OF THE CABLE CONNECTION CAN CAUSE REDUCED WATER RESISTANCE AND POTENTIAL LOSS OF ELECTRICAL GROUND. THERE IS ALSO A POSSIBILITY THE TRAILER LIGHTS MAY FAIL TO ILLUMINATE WITHOUT THE OPERATOR'S KNOWLEDGE.
PACCAR IS RECALLING 172 MY 2007 KENWORTH T800 SHORT HOOD, W900 LONG HOOD AND T600 TRACTOR/TRAILERS EQUIPPED WITH SAF-HOLLAND SIMPLEX FIFTH WHEELS. IF THE PIVOT BOLT JOINT FOR THE LEVER BAR IS OVER TORQUED, THE SPACER DEFORMS, AND MAKES CONTACT WITH THE LEVER BAR. THIS CONDITION COUPLED WITH CORROSION ASSOCIATED WITH THE SEASONAL DRY OUT, CAN AFFECT THE LOCK SYSTEM OF THE FIFTH WHEEL, PREVENTING THE FIFTH WHEEL JAW FROM LATCHING SECURELY AROUND THE TRAILER KING PIN.
CERTAIN TRUCKS EQUIPPED WITH EATON SYNFLEX ECLIPSE BRAND EXTRUDED NYLON AIR BRAKE HOSE TUBING FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 106, "BRAKE HOSES." THE TUBING WAS MANUFACTURED WITH ONLY FOUR LAYERS OF NYLON MATERIAL, INSTEAD OF THE SPECIFIED FIVE LAYERS.
ON CERTAIN TRUCKS EQUIPPED WITH CATERPILLAR C11, C13 OR C15 ENGINES, THE OIL FILL CAP CAN BECOME DISLODGED DUE TO CAP DAMAGE OR IMPROPER INSTALLATION AND BECOME LODGED IN THE U-JOINT OF THE STEERING DRIVELINE AND STEERING GEAR.
