DETROIT (AP) - Three Ohio drivers are suing Ford Motor Co., claiming the company's six-cylinder EcoBoost engine is defective.
The lawsuit says the 3.5-liter V6 EcoBoost engine can shudder, shake and rapidly lose power while drivers are trying to accelerate. It says more than 100 drivers have complained about the engine to the National Highway Traffic Safety Administration.
Ford has been selling vehicles equipped with the V6 EcoBoost since 2009. The engine is used on the F-150 pickup, Ford Taurus and Lincoln MKS sedans and the Explorer, Flex and Lincoln MKT utilities.
The suit claims Ford has acknowledged the problems in messages to dealers, but hasn't informed owners.
Ford declined to comment Tuesday, saying it hasn't seen the lawsuit.
The suit was filed late last week in U.S. District Court in Columbus, Ohio.
