Earlier this year, we found out that a class-action lawsuit had been filed against Ford over issues with its EcoBoost V6 engines. It turns out, those aren’t the only EcoBoost engines in legal hot water. Another class-action suit, this one filed in California, is taking on the four-cylinder line of turbocharged engines. It covers basically all the different four-cylinder variants from the humble 1.5-liter that was offered in the Ford Fusion, up to the 2.3-liter units in the Ford Mustang.
