Navistar to Pay $159 Million to Settle MaxxForce Lawsuit

May 30, 2019

Navistar has entered into a $159 million class-action settlement with fleets and truck owners who purchased 2011-2014 11-liter and 13-liter MaxxForce engines. The settlement resulted from Navistar’s use of exhaust gas recirculation, or EGR, to control nitrous oxide emissions. According to, the technology failed to meet federal standards.

According to CCJ Digital, that engine line contains defects that piled up “millions of dollars” in warranty claims for the company. The MaxxForce line in has led to several years of billion dollar losses for the company.

According to, trucks with faulty MaxxForce engine technology will qualify for a $2,500 payout, or a $10,000 rebate on a new truck. Not including the latest settlement, Navistar has spent over $1 billion in warranty costs to cover reliability and fuel-economy problems with the trucks, according to

Although the engines caused Navistar to lose almost half its market share, says the company expects the settlement will “accelerate our efforts” to move past the MaxxForce hurdle.
