Fatal crashes in the US
From 2020 to 2023, 17 T300 vehicles were involved in crashes on US public roads in which someone died, and 3 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.

30 campaigns cover the T300; the latest 12 are below.
PACCAR IS RECALLING MODEL YEAR 2008-2010 KENWORTH T300, T270, AND T370, MODEL YEAR 2009-2010 T800 AND PETERBILT MODEL YEAR 2008-2010 335, 340, AND 367 VEHICLES BUILT ON CUMMINS' DIESEL ENGINE. THE VEHICLES MAY BE DESIGNED WITH A HARD WIRED, DASH-MOUNTED SWITCH THAT ENABLES THE VEHICLE OPERATOR TO INHIBIT AFTERTREATMENT DIESEL PARTICULATE FILTER REGENERATION IN ENVIRONMENTS WHERE THE OPERATOR BELIEVES IT MAY BE UNSAFE FOR ELEVATED EXHAUST TEMPERATURES. DUE TO AN ISSUE WITH THE LOGIC IN THE ECM SOFTWARE IN THESE ENGINES, THE SWITCH MAY NOT FUNCTION CORRECTLY, LEADING THE OPERATOR TO BELIEVE THAT THE SWITCH IS IN "INHIBIT" MODE WHEN IT IS NOT.
PACCAR IS RECALLING 36 MY 2007-2008 T270, T370 AND MY 207 T300 TRUCKS EQUIPPED WITH DUAL UNDER-CAB FUEL TANKS AND AN IN-CAB BATTERY BOX (ICBB). A HARNESS SUPPORT BRACKET MOUNTED ON THE UNDERSIDE OF THE CAB MAY COME IN CONTACT WITH THE FUEL LINE AT THE TOP OF THE FUEL SPLITTER VALVE.
PACCAR IS RECALLING 6,169 MY 2008 KENWORTH T300, T660, T800, T2000, W900 AND C500 VEHICLES AND MY 2008-2009 PETERBILT MODELS 365, 367, 384, 387, 388, 389 AND 389 KITS. CERTAIN DOOR LATCH ASSEMBLIES ON THESE VEHICLES FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 206, 'DOOR LOCKS AND DOOR RETENTION COMPONENTS." THE ROTOR IN SOME OF THESE DOOR LATCH ASSEMBLIES DID NOT RECEIVE THE PROPER HEAT TREATMENT AND MAY BE SOFT.
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 CUMMINS ISC OR PACCAR PX8 ENGINES, THE JUMPER WIRE BETWEEN THE GRID HEATER RELAY TO THE FUSE BLOCK HAS BEEN ROUTED IN SUCH A WAY THAT THE POTENTIAL EXISTS FOR IT TO RUB AGAINST THE RADIATOR SUPPORT.
ON CERTAIN TRUCKS, THE AXLE HOUSINGS MAY HAVE BEEN MANUFACTURED WITH STEEL THAT WAS OUT OF SPECIFICATION WHICH COULD RESULT IN A FATIGUE FAILURE OVER TIME.
ON CERTAIN TRUCKS, THE WIRING, PARTS, OR TRANSMISSION PROGRAMMING REQUIRED FOR THE AUTO NEUTRAL FEATURE TO FUNCTION AS DESIGNED WERE EITHER NOT INSTALLED, CONNECTED, OR PROGRAMMED PROPERLY.
CERTAIN TRUCKS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS." THE TRAILER LIGHT LINE MAY HAVE BEEN ROUTED USING TOO TIGHT OF A BEND RADIUS. THIS ROUTING METHOD COULD CAUSE THE WIRES WITHIN THE HARNESS PLUG TO BE PULLED AWAY FROM THE CHASSIS PLUG RESULTING IN AN INTERMITTENT OR COMPLETE ELECTRICAL POWER LOSS TO THE TRAILER.
AN INCORRECT SWITCH WAS INSTALLED IN THE CRUISE CONTROL SYSTEM ON CERTAIN MODEL T300 TRUCKS.
ON CERTAIN TRUCKS EQUIPPED WITH HYDRAULIC BRAKES, THERE MAY BE A DEFECT IN THE ANCHOR BOLT OF SOME BOSCH MODEL #305 PARKING BRAKE ASSEMBLIES. A DIFFERENT COATING WAS APPLIED TO THE BOLT WHICH DID NOT MEET PACCAR SPECIFICATIONS. THIS COULD REDUCE THE FATIGUE LIFE OF THE BOLT AND LEAD TO PREMATURE FAILURE.
ON CERTAIN TRUCKS, THE POWER FEED HARNESS P92-1993 TERMINALS WERE NOT PROPERLY CRIMPED.
ON CERTAIN TRUCKS BUILT WITH CUMMINS ISC AND ISL ENGINES, PLUGS WERE ASSEMBLED INCORRECTLY CREATING STRESS AND CRACKS WHICH COULD CAUSE AN OIL LEAK.
