What Are Some MaxxForce 7 Problems?

According to CCJ Digital, lawsuits filed against Navistar-International, the company that makes MaxxForce engines, claim multiple problems with the MaxxStar engines that Navistar concealed from buyers. The lawsuit claims that the engines could not handle the heat and pressure they generate, causing exhaust leaks and EGR cooler failures.

Although this lawsuit does not apply solely to the MaxxForce 7 engine, the class action suit included any MaxxForce International engine purchased between 2008 and 2013. Most claims in the suits involve early engine failures and breach of security laws by the manufacturer. One claimant says that the engines have very low trade-in and resale values because the problems with the engines are widely known.
