| Bulletin | Summary |
|---|---|
| 10254164 | Certain C500/T440/T470/T660/T680/T800/T880/W900 chassis may have air tank reservoirs that do not meet air volume requirements per FMVSS/CMVSS 121 Air Brake Systems. This bulletin will be updated when repair parts and procedures are available. |
| 10244494 | E304: PACCAR MX-11 and MX-13 EMY2016 NOx and N2O Exceedance Emissions Recall Certain vehicles with PACCAR MX-11 and MX-13 EMY2016 engines with less than 300,000 miles (482,803 km) have been shown, in testing, to exceed regulatory limits for NOx and N2O emissions. This bulletin now applies to both Canadian and U.S.-registered vehicles. Software is now available to remedy this emissions non-compliance. NOTE California-registered vehicles that received a letter must have the software updated AND California documentation completed regardless of vehicle mileage. |
| 10238385 | Emissions Recall Certain Vehicle Model Year 2017-2019 chassis equipped with EPA2017 compliant PACCAR MX-13 engines have an EGR flex pipe that can develop cracks and leak untreated exhaust. The EGR Flex pipe will be replaced if it has a suspect part number. |
| 10238382 | Certain chassis with Engine Model Year 2016-2021 PACCAR MX-11/MX-13, or EPA13 and EPA21 Cummins ISX12/ISX15/X15 engines that had a previously failed DEF sensor and with DEF sensor software disabled due to industry DEF sensor shortages will now be able to receive a replacement DEF sensor, DEF tank heater coolant control valve, and re-enabled DEF diagnostic software. Please note that chassis equipped with PACCAR PX engines will be eligible for this repair at a future date when software is available. |
| 10238376 | E279: PACCAR MX-13/MX-11 Engine MY17 Software Incorrectly Sets DTC P1092 PACCAR MX-13/MX-11 Engine MY17 Software Incorrectly Sets DTC P1092 Emission Recall - PACCAR MX-13/MX-11 MY2017 software incorrectly sets DTC P1092, which could result in reduced available engine torque and/or engine protection mode. An engine software update is available that corrects the issue. |
| 10232496 | Certain Model Year 2021-2024 chassis with PACCAR MX engines and optional fuel filter restriction virtual gauge may display incorrect restriction levels. The virtual gauge will be temporarily disabled until a revised sensor strategy is developed. |
| 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. |
| 10218895 | Kenworth is providing guidance for PACCAR MX Engine Composite Oil Pan leak troubleshooting to avoid over-repairs and to provide warrantable repair guidance. Oil leaks, if not repaired, can lead to severe engine damage. |
| 10208770 | 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 |
| 10203780 | Non-Safety Campaign - The TPMS ECU is not communicating properly with TPMS sensors. The result is a delay or failure of communication between the TPMS ECU and the TPMS sensors , causing inaccurate TPMS readings. A firmware update resolves 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. |
| 10198762 | Information Only C hassis equipped with MY2021 B EPA emission s standards will be shipped through atleast the end of the 2021 calendar year without particulate matter (PM) sensors installed . |
