14-0432022-10-05. Service bulletin. SUSPENSION. Fix-As-Fail On certain chassis with Low Air Leaf Suspension or Low-Low Air Leaf Suspension, the Height Control Valve (HCV) arm may be rubbing on other components when the bend in the arm is facing outboard. Flipping the bend in the HCV arm inboard prevents the rub.
13-0602022-09-06. Service bulletin. SERVICE BRAKES. The service information for Bendix Air Dryer maintenance is being updated to include new procedures.
51-0132022-03-04. Service bulletin. EQUIPMENT. Due to major data carriers phasing out 3G networks, chassis currently utilizing first generation Peoplenet Mobile Gateway (PMG001) will experience severe 3G service degradation as early as January of 2022. Chassis currently utilizing 3G antennas as a primary antenna may experience this degradation.
34-0902022-03-04. Service bulletin. EQUIPMENT; EXTERIOR LIGHTING; ELECTRICAL SYSTEM. A frame mounted left-hand marker light bracket interferes with the rear fuel tank fill location. A redesigned bracket can be purchased that relocates the marker bracket to the front fuel tank bracket to eliminate interference.
21PBN2022-02-04. Service bulletin. FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY; ELECTRICAL SYSTEM; EQUIPMENT. Interim Safety Recall – Methane detection system will not warn the operator if the system loses power. The driver could be unaware of an issue with the methane detection system or excessive methane present, increasing the risk of a fire, crash and/or personal injury. The repair procedure will be added when it is available.
T0122022-01-06. Service bulletin. POWER TRAIN. Non-Safety Campaign: Drivers of vehicles equipped with PACCAR TX-12 transmissions may experience harsh shifts and gear grinding noise. Premature Main Drive Gear damage may occur due to clutch housing and main case countershaft bearing bore wear.
21PBM2022-01-06. Service bulletin. SERVICE BRAKES, HYDRAULIC. Safety Recall – Work Brake May Unintentionally Disengage – NHTSA ID: 21V906, TC: 2021-713. The work brake (also known as winch brake) may unintentionally disengage during winching operations, releasing the service brakes, increasing the risk of crash or injury. The VECU software will be updated to correctly set the speed interlock parameter.
26-0382022-01-06. Service bulletin. POWER TRAIN. Non-Safety Campaign: Eaton Endurant transmissions may experience premature Main Drive Gear damage due to clutch housing and main case countershaft bearing bore wear. A Clutch Housing Front Cover Kit will be installed to address the issue.
42-0592021-12-03. Service bulletin. ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION MOTOR:CONTROLLER; ENGINE AND ENGINE COOLING:COOLING SYSTEM:FAN; ENGINE AND ENGINE COOLING. Non-Safety Campaign - Vehicles with a Cummins X15 engine and Horton fan drive may set Diagnostic Trouble Code (DTC) 6637 and/or 3838 due to fan speed that results in the fan remaining activated until the power is cycled. A new controller will resolve the issue.
43-0712021-10-05. Service bulletin. FUEL SYSTEM, DIESEL. Fix-As-Fail – Due to undersupply issues, only a limited supply of Diesel Exhaust Fluid (DEF) sensors are available. As a temporary solution, after PACCAR confirms a DEF sensor is not available, a temporary software update will allow a vehicle to continue operation with a failed DEF sensor by disabling the DEF sensor diagnostics.
21-PBF2021-07-06. Service bulletin. EXTERIOR LIGHTING. Safety Recall – Interim Notification - The Daytime Running Lamps (DRLs) may turn off while the vehicle is in motion and the headlamps, fog lamps or turn signals are not on. This is non-compliant with Canadian Regulation CMVSS 108, which states that the DRLs must be on while the vehicle is in motion without certain other lamps being activated. This bulletin will be updated when a repair is available.
21-PBD2021-07-06. Service bulletin. FUEL SYSTEM, GASOLINE. Safety Recall – Cummins Fuel Rail Leak – NHTSA ID: 21V391 / TC: 2021-323, Cummins Recall: C2423. Cummins PX9 and ISX12 fuel rails may leak around a sealing washer, potentially resulting in fuel leaks. Undetected prolonged diesel fuel spray in the presence of an ignition source may increase the risk of fire.
E2652021-06-02. Service bulletin. ENGINE AND ENGINE COOLING. Selected engines have been identified to receive a camshaft inspection and an update for improved camshaft lubrication.
02-1602021-03-10. Service bulletin. VISIBILITY; EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY; VISIBILITY:WINDSHIELD WIPER/WASHER. Information Only – Windshield washer pumps have a high No Trouble Found rate. Washer pumps may fail to spray due to a clogged filter.
32-0182021-03-10. Service bulletin. ENGINE AND ENGINE COOLING. Non-Safety Campaign – Chassis with the City Horn option may generate unexpected alerts. A VECU software update is available to resolve the issue.
32-0172021-03-10. Service bulletin. ELECTRICAL SYSTEM. Non-Safety Campaign – The batteries may drain quickly due to the VECU not going to sleep. Updated VECU software is available to resolve the issue.
116-12021-02-01. Service bulletin. EQUIPMENT. SmartNav 2.0 Hardware retrofit for quality validation and vehicle validation units.
26-0372021-01-06. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN; EQUIPMENT ADAPTIVE/MOBILITY. Fix-As-Fail - Prior versions of Eaton Endurant transmission software may be prone to setting Linear Clutch Actuator (LCA) fault codes leading to possible LCA hardware replacement.
26-0352021-01-06. Service bulletin. POWER TRAIN; EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT. Non-safety campaign: Vehicles equipped with an Eaton Endurant 12 speed transmission may experience transmission service lamp activation, no gear engagement from neutral, and/or DTC 511 FMI 7 or 10 is set. Resolution is to update the transmission software and calibrations.
T0112021-01-06. Service bulletin. POWER TRAIN. Fix-As-Fail - Prior versions of PACCAR transmission software may be prone to setting Linear Clutch Actuator (LCA) fault codes leading to possible LCA hardware replacement.
01-0792020-12-05. Service bulletin. ELECTRICAL SYSTEM. Fix as Fail The HVAC system, on model 579 and 567 vehicles manufactured since 1/20/2012 may have inadequate temperature control. The HVAC may intermittently stop blowing cold air, typically after a truck restart. Driver may notice the system returns to normal after key cycle. The remedy is updating HVAC software.
13-0552020-11-05. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; SERVICE BRAKES, AIR. Fix as Fail: Peterbilt has introduced an improved mounting bracket for low mount air tanks for vehicles built between January 01, 2017 and July 06, 2020. Torsional vibration may stress the currently-installed brackets and cause them to fail near the bottom of the frame rail.
20PBE2020-10-06. Service bulletin. POWER TRAIN; EQUIPMENT. Safety Recall: Peterbilt has decided that a condition could exist in certain model 348, 365, 367, 389, 520, and 567 vehicles built between 11/19/2019 and 4/09/2020. Vehicles equipped with Watson & Chalin SL2065 lift axles may have lower rear pivot bolts that are not long enough to sufficiently engage the locking feature of the corresponding nuts. In some cases, this condition may cause a loss of clamp load of the pivot joint (arm to axle). Extended use of the lift axle in this condition can result in foreign object debris on the roadway, increasing the risk of a crash and/or injury.
02-1582020-09-03. Service bulletin. EQUIPMENT; STRUCTURE; EQUIPMENT ADAPTIVE/MOBILITY; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Fix as Fail: Peterbilt has determined that certain model 348, 365, 367, 382, 384, 386, 388, 389, 567, 579, and 587 trucks, built between 4/13/2010 and 3/16/2020 and equipped with a flush mounted battery box, utilized rubber washers that could rub through and cause the aluminum box mounting tabs to rub directly on the steel frame brackets. This could result in cracked battery box mounting angles. Resolution is to add the reinforcement bracket(s) to affected vehicles.
14-0262020-08-05. Service bulletin. STRUCTURE. Fix as Fail: Peterbilt has designed an improved Secondary Chassis Module (SCM) bracket which is available for Models 567/579 built between January 01, 2018 and February 20, 2020. SCM brackets impacted by torsional stress may separate from the back of cab crossmember.
