Thomas Built Buses and Detroit Expand Warranty Coverage for DD5, DD8 Engine After-treatment Systems

HIGH POINT, N.C. — Industry leader Thomas Built Buses, Inc., along with Detroit Diesel Corp., a leading manufacturer of heavy and medium-duty diesel engines, have expanded the warranty options for the Detroit DD5 and DD8 engine after-treatment systems.

The Saf-T-Liner C2.


Currently, a standard warranty of 5 years/100,000 miles/160,000 km, including 100 percent parts and labor, covers both the engine and the after-treatment system of the DD5 and DD8 engines. Now, customers have the option of adding on an extended warranty for just the after-treatment system.

“We continue to stand behind the quality and durability of our school buses and now our new Detroit engines,” said Caley Edgerly, president and CEO of Thomas Built Buses. “The after-treatment systems of our new Detroit DD5 and DD8 engines are one-of-a-kind with some of the greatest fuel efficiency in the marketplace; and variable cam phasing, which in the end, cause less wear and tear on the after-treatment system. This results in far [fewer] faults and a system that requires far less maintenance than conventional after-treatment systems. We are pleased to offer our customers a state-of-the-art after-treatment system and additional peace of mind through this extended coverage.”

Coverage options vary but can cover up to 10 years with unlimited miles/km. Detroit’s after-treatment extended warranty will cover only the after-treatment system. Additional engine warranty coverage is also available to cover progressive damage to the engines. For complete information about Thomas Built Buses or warranties, customers can consult their local dealer.
