According to a study by J.D. Power and Associates, a coming ramp-up in production plus the release of new 2010 EPA-compliant engines may negatively impact truck quality.
Overall quality of heavy-duty trucks has improved substantially in 2011, compared with 2010, but whether these quality gains can be sustained in the face of greater production and new emissions regulations remains in question, according to the J.D. Power and Associates 2011 U.S. Heavy-Duty Truck Customer Satisfaction Study.
