Safety advocates encouraging a recall of certain 2002-2004 Ford Escape vehicles are also asking the National Highway Traffic Safety Administration (NHTSA) to include the 2002-2004 Mazda Tribute in their investigation. According to the group, both sport utility vehicles (SUV) are similar vehicles built on the same assembly line. In 2004 Ford and Mazda issued identical recalls for unintended acceleration caused by an accelerator cable that may not return to the idle position. Ford later issued a technical service bulletin that warned dealers that an improper repair could lead to an adjacent cruise control cable being damaged and snagging on the engine cover causing unintended acceleration. The Center for Auto Safety say that because the vehicles are so similar and there is no way of knowing whether the recalls were carried out correctly, Ford and Mazda should issue a recall to ensure the safety of the vehicles.
