What Peterbilt told its dealers about the 2019 Peterbilt 579: known faults, fixes and updates.
| Bulletin | Summary |
|---|---|
| 11010926 | Info Only Unnecessary starter replacements can result from customer complaints regarding engine starting issues. A new Starter Troubleshooting Guide has been created to provide a comprehensive list of starting system checks, which should reduce unnecessary starter replacements and associated warranty claims. Engine starting system warranty claims now require a completed Starter Checklist, a Battery Pack Midtronics Report, and a Cable Drop Midtronics Report. Claims filed without these documents may be denied. |
| 11009757 | 7/700 Service Agreement - Letter Only. |
| 11005516 | Fix As Fail The height control valve (HCV) rod on vehicles with low air leaf suspensions is prone to toggling over center during rough road conditions. With full suspension articulation, HCV bracket flexes and toggles over center the HCV linkage, which results in either deflated airbags or makes them unable to inflate. Fix-as-fail start date is 07/30/2024. |
| 10245639 | Fix As Fail Updated: Two part numbers added: 1818119 DPF Delta Pressure Sensors for MX-13-2 EMY18 2200138 DPF Delta Pressure Sensors for MX-13 -2, EMY19 Per Environment and Climate Change Canada (ECCC) regulations and guidance (Canadian Environmental Protection Act, 1999 (CEPA)), a letter has been provided to owners of Canadian registered chassis that provides a list of emissions components that have been reported (to ECCC) as having a defect. |
| 10244481 | A testing procedure has been created for the coolant level sensor on model 520. |
| 10243354 | For all Peterbilt chassis equipped with an air shifted PTO. Oil from the air shift cover of the PTO may leak into the air line, causing the EOA solenoid to become inoperative. |
| 10238387 | Fix-as-Fail - HVAC Intermittently Stops Blowing Cold Air |
| 10235714 | Fix As Fail Certain 579, and New Model 579 chassis that were manufactured with a Bendix forward looking camera system may experience bracket failure causing the bracket and camera to fall from the windshield. |
| 10235704 | Fix As Fail All New Model 579 chassis with Bendix radar opti on may have a harness rub against the radiator that is causing possible damage. |
| 10232162 | Fix As Fail Chassis that were manufactured with certain battery cable routing brackets may experience rubbing or chafing of the battery cables. |
| 10232160 | Certain Engine Model Year 2018 PACCAR MX-11 engines must have the crankcase pressure sensor replaced due to contamination during assembly. |
| 10231101 | This campaign is the final opportunity to replace the oil filter screw cap to reduce occurrences of broken bypass valve tabs. Broken oil valve tabs can cause oil flow obstruction to critical engine parts, resulting in serious engine damage. Customers that do not receive this repair may be responsible for progressive engine damage caused by broken oil bypass valve tabs. |
| 10227172 | 21PBN LNG/CNG Methane Detecti on System Will Not Warn Operator if System Loses Power NHTSA ID:21V00N, TC: 2021-793 |
| 10225578 | Info Only - PACCAR is introducing Over-the-Air (OTA) software updates for engine MY17 and newer chassis equipped with Cummins X15, X12, ISX12, ISX12N, L9N, PX-7, and PX-9 engines The technology will leverage the existing Remote Diagnostic cs hardware to deliver secure software updates remotely. This will reduce downtime and save on maintenance costs for eligible vehicles. |
| 10222269 | 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. |
| 10219235 | The service information for Bendix Air Dryer maintenance is being updated to include new procedures. |
| 10210949 | A roof fairing reinforcement kit increases structural support for one-piece 579 roof fairings that are experiencing fatigue from external forces such as reverse towing. |
| 10208758 | 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. |
| 10208756 | 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. |
| 10207154 | 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. |
| 10206097 | 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. |
| 10206090 | 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. |
| 10206084 | 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. |
| 10203783 | 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. |
| 10201965 | 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. |
