A class action lawsuit was filed against Ford Motor Company in May 2010 proceeding Ford's recall. This lawsuit was filed by Plaintiff Aaron Martin against Defendant Ford Motor Company. In this lawsuit, documents were introduced which showed Ford's testing of the Benteler Axle in March 1998 resulted in failure of two out of the eleven axles tested. In August 1998, Ford determined the cause of this failure was improper heat treating. In September 1998, the axle manufacturer Bentley Automotive agreed with Ford's findings. In October 1999, Ford's internal documents show lab testing proved the axle life could be doubled by heat treating, but would require initial retooling cost and result in $3.45 piece cost increase. No changes were made until March 2003. Subframe corrosion In March 2011, the National Highway Traffic Safety Administration and Ford announced another Ford Windstar recall over corrosion concerns. 425,288 of the model year 1999–2003 Windstar vans originally sold or currently registered in some cold weather states are part of the recall. The problem involves rusting of the subframe. Most of the corrosion occurs on the passenger side of the subframe. If the subframe collapses while driving, the vehicle could potentially lose all steering control and end up in an accident. According to the NHTSA action #PE10026, some Ford Windstar owners had their drive axle detach from the transmission. Ford is offering alternative transportation to owners if their vehicle is unsafe to drive. If the minivan can't be repaired, Ford will repurchase the vehicle. IIHS crash test results The 1999–2003 Ford Windstar received an "Acceptable" rating by the IIHS for fair structural performance, moderate injuries to the left foot, and fair dummy control. Although most redesigned vehicles outperform their predecessors to cut down insurance costs and possible injuries to the driver, this generation Windstar did not perform as well as its first generation predecessor. The NHTSA graded the minivan an overall rating of 5 stars in both the frontal and side impact tests. Yearly American sales Third generation (Ford Freestar; 2004–2007) For the 2004 model year, the third generation Ford Windstar was released; as part of a mid-2000s rebranding of the Ford car model line with nameplates starting with the letter "F", the Windstar was renamed the Ford Freestar. Sharing the MV1 platform with the 2000-2003 Ford Windstar, the primary initiative of the $600 million redesign focused on driveline reliability, an issue that had plagued the
