Marion Body Works Inc.

(Marion) is recalling certain 2021 Freightliner M2, 2020 Kenworth T3, and 2018 International SR525 emergency vehicles equipped with certain Cummins diesel engines.

  • Which ones, by part or lot: the recall’s report on NHTSA’s site gives them where the maker did; this file gives part numbers only where its maker listed them.
  • How many have been returned or fixed isn’t in the notice.
