Daimler Trucks North America (DTNA) has added to the Select Limited Warranty coverage options available through its used truck retail network, SelecTrucks.  The new warranty will cover the aftertreatment system (ATS) on both Detroit and Cummins engines, a service not offered by others, the company says. The warranty is available on used Freightliner and Western Star trucks.

Covered repairs can be completed at any Freightliner or Western Star authorized service center in the U.S. and Canada.

The new ATS warranty covers major system components including the diesel oxidation catalyst (DOC), the selective catalyst reduction (SCR), and both the doser injector and the diesel exhaust fluid (DEF) injector. The coverage also includes temperature and pressure sensors.

A key feature included in this warranty is coverage for the failure of the diesel particulate filter (DPF) which could potentially cost customers something in the range of $3000. The cost to replace an entire ATS without this warranty could easily exceed $10,000, says DTNA.
