NHTSA Campaign Number: 24V145
Manufacturer PACCAR
Incorporated
Components SERVICE BRAKES, AIR
Potential Number of Units Affected 697
Summary
PACCAR Incorporated (PACCAR) is recalling certain 2009-2021 Kenworth C500, 2014-2016 Kenworth T440, 2009-2015 Kenworth T660, 2015-2024 Kenworth T680, 2009-2024 Kenworth T800, 2013-2023 Kenworth T880, 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.”
Remedy
Dealers will install the correct volume air tanks, free of charge. Owner notification letters are expected to be mailed April 23, 2024. Owners may contact PACCAR customer service at 1-425-828-5888. PACCAR’s number for this recall is 24KWD.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
Chronology :
05-19-23: Safety and Compliance was notified by engineering that a drawing issue was identified which overrepresented the volume of certain air tanks and may result in incorrect air tank volume calculations per vehicle. No affected vehicles in field identified to have insufficient air volume due to the drawing issue, but additional vehicles showed insufficient air volume with unknown root cause. Investigation opened.
06-06-23: Current estimated affected population is 71 vehicles. Investigation and backlog search continues.
06-15-23: Investigation ongoing.
02-14-24: Investigation summarized for Safety Committee Review.
02-16-24: Safety Committee meeting held. The Safety Committee concurs that a regulatory noncompliance exists and that the affected population shall be recalled.
02-19-24: Final corrective action implemented. Backlog search was completed and did not identify any additional vehicles to include in the affected population.
As of February 16, 2024, PACCAR received zero warranty claims and zero reports about the trucks in the field that may be related to the issue. Zero reports of deaths or injuries have been received.
