The recall affects trucks built with RH Shift Stalk part numbers Q21-6155-000, Q21-6164-000 and Q21-6165-000 and their released dash variations built from Nov. 9, 2020, to Jan. 31, 2024, that have not previously had warranty claims regarding the RH Shift Stalk. The components were manufactured by Kongsberg Automotive.
As of March 8, 2024, when the recall was issued, Paccar received 11,395 warranty claims and 56 reports about trucks in the field that are related to the problem between Jan. 24, 2021, and March 3, 2024. No reports of deaths or injuries have been received.
