Why The Truck You Bought In 2008 Was Designed To Fail By 2015

Why The Truck You Bought In 2008 Was Designed To Fail By 2015 The failure of the 6.0-liter Power Stroke, the 6.4-liter Power Stroke, and the first generation of DPF-equipped Duramax and Cummins trucks was not bad engineering and it was not bad luck. It was the predictable downstream consequence of an EPA enforcement action from October 1998 that forced seven diesel engine manufacturers to meet the 2004 NOx standard fifteen months ahead of schedule — and the only technology available in that timeframe was exhaust gas recirculation hardware that had not been field-proven at scale in American work trucks. The 7.3-liter Power Stroke was not replaced because something better was built. It was removed from production because its architecture had no provision for the EGR system the consent decree required. More than two million 7.3-liter engines had been produced. The engine that replaced it in fall 2002 had failed its own pre-production durability testing. Ford approved it anyway. By February 2007, the 6.0-liter's warranty costs had exceeded $400 million — 80 percent of Ford's entire engine warranty spending from 10 percent of its engine volume. Ford sued Navistar for $493 million. Thirty-five class action lawsuits were consolidated into federal MDL-2223, covering more than one million claimants. The 2007 EPA mandate then added diesel particulate filters — and the 6.4-liter Power Stroke, the LMM Duramax, and the first-generation 6.7-liter Cummins all entered service carrying both EGR and DPF hardware on a regulatory timeline. The pre-buy before the 2007 mandate was the largest diesel truck pre-buy in American history. The 2027 mandate is generating the same pattern right now.
