Dear Kenworth Customer,
Kenworth Truck Company has determined that certain T680, T800, T880, and W900 chassis manufactured from 01/23/2014 through 02/21/2017 with
Engine Model Year 2016 PACCAR MX-13 or MX-11 engines fail to conform to Federal emission control requirements.
If you no longer own this vehicle, we would appreciate you using the below contact information to advise us of the new owner’s name and
address.
Your vehicle has been identified as having an affected emission control system. The issue pertains to the OBD monitoring system and has no negative
impact on tailpipe emissions. These repairs, including engine software, and labor, will be performed at no charge to you. If this repair is not completed, it
may cause the vehicle to fail a vehicle inspection when such tests are required under state law.
Federal regulation requires that any vehicle lessor receiving this recall notice forward a copy of this notice to the lessee within ten days.
