EPA-compliant Engines a Drag on Class 8 Satisfaction

July 2, 2012

According to J.D. Power and Associates, heavy-duty truck customers are experiencing problems with EPA-compliant diesel engines and those problems are driving down heavy-duty truck quality and customer satisfaction.

The company's 2012 U.S. Heavy-Duty Truck Customer Satisfaction Study, detailed in Fleet Owner, said that overall customer satisfaction with heavy-duty trucks declined versus 2011, primarily due to an increase in the number of problems experienced. Navistar has been particularly hard hit, with increased warranty costs and the reversal of an EPA ruling allowing it to sell non-compliant engines.

“Emission-related technology results in a high rate of problems, particularly with ECM calibration, exhaust gas recirculation (EGR) valves and engine sensors,” said Brent Gruber, director of the commercial vehicle practice at J.D. Power. “The new, more complex engines are resulting in more problems and downtime.”
