Mack Trucks, Inc.

DEAR MACK TRUCK OWNER:

Extended Warranty Coverage ID U107
OWNER NOTIFICATION LETTER Jan 2019

This notice is sent to you in accordance with the requirements as prescribed by the California
Air Resources Board (CARB).
Mack has determined that certain vehicles equipped with a model year (“MY”) 2014 MP8 model
engine may be equipped with unit injectors that may not fulfill expected performance criteria
pertaining to the life expectancy of a unit injector.
This potential issue has no impact on fuel economy, driveability, performance, or safety of the engines.
However as the unit injector is an emissions related component, Mack is providing extended warranty
provisions.
According to our records, one or more vehicle(s) sold to you may have this condition. Mack is
addressing this condition through an extended warranty offering of 7 years or 435,000 miles for the unit
injectors, whichever occurs first, and will provide the repairs free of charge, for engines that exhibit the
condition up through the extended warranty period. Repair costs may be reimbursed if prior repair was
incurred outside of original warranty provisions but within the warranty extension. Instruction on how
to submit a claim for these repairs is provided at the end of this letter.

CONDITION:
