What’s wrong with it?
Insufficient air volume can reduce braking performance and increase the risk of a crash.
PACCAR Incorporated (PACCAR) is recalling certain 2009-2021 Kenworth C500, 2012-2021 Kenworth T440, 2009-2015 Kenworth T660, 2015-2024 Kenworth T680, 2009-2024 Kenworth T800, 2009-2020 Kenworth T370, 2014-2023 Kenworth T880, 2011-2016 Kenworth T470, 2023 Kenworth T480, and 2009-2019 Kenworth W900 vehicles.
The air tanks have an insufficient volume of air for the brake system.
As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, “Air Brake Systems.”
