Ford is sued by three drivers from Ohio who claim that the automaker’s six-cylinder EcoBoost engine is defective.
According to the lawsuit, the 3.5-liter V6 EcoBoost engine shudders, shakes and then quickly lose power when drivers accelerate. Two of the plaintiffs, a married couple, claimed that their 2010 Ford Taurus SHO lost power and stalled several times, while the third plaintiffs says that his F-150 pickup lost power when he was accelerating.
The NHTSA received more than 100 complaints related to the V6 EcoBoost loss of power, but the agency has not opened an investigation and Ford has not recalled any vehicles. The lawsuit claims that the US automaker has informed its dealerships about this issue, but not the owners too. Since 2009 Ford has been selling the V6 EcoBoost engine, which comes as an option for the Taurus SHO, Ford Flex, Lincoln MKS and Lincoln MKT sedans 2010-2013 model years, 2013 Ford Explorer Sport and 2010-2013 F-150 pickup.
There were no complaints regarding Ford’s four-cylinder and three-cylinder EcoBoost engines, even if all three engine models use turbocharging and direct injection, to provide the power of a larger engine and the economy of a smaller one.
