The verdict in the Milan case is the latest chapter in Navistar's continued headache over its MaxxForce engine line, which it discontinued without fanfare in recent years. In addition to facing lawsuits from fleets over the engines' reliability and the ouster of some of its top executives, the company also faced criminal charges from the Securities and Exchange Commission related to the MaxxForce line. The company reached a settlement agreement with the SEC last March, and the criminal charges were dropped. Navistar has also seen billions of dollars in financial losses in the last half decade stemming from warranty issues related to the MaxxForce engine line.
