Lieff Cabraser Heimann & Bernstein, LLP, a national law firm, is seeking class action status for lawsuits it filed last week against Navistar regarding the OEM’s Maxxforce Advanced EGR (exhaust gas recirculation) diesel engine models.

The current lawsuit involves three motor carries in California, Illinois, and Washington State regarding the MaxxForce EGR engines powering their 2008-2013 model trucks, alleging that the Maxxforce Advanced EGR engine is defective and that the alleged defects lead to repeated failures – well before completion of its intended and expected useful life – requiring costly repairs often at the expense of owners and lessees.

Lead attorney Jonathan Selbin further alleged in a statement that when those trucks were brought in for repairs during the warranty period, Navistar didn't properly repair the emission system and instead replaced them with another equally defective failure-prone system.

"The problems with these engines have cost buyers and lessees – including many small, family-owned businesses – thousands of dollars," he added. "In some cases, the unexpected mechanical problems endangered owners' ability to earn a living. The lawsuit seeks to hold Navistar responsible for the quality of its engines and ensure that buyers and lessees of Navistar trucks get what they paid for."

The class action status proposed by Lieff Cabraser Heimann & Bernstein follows on the heels of similar lawsuits filed by the law firm of Miller Weisbrod earlier this week.
