The National Highway Traffic Safety Administration (NHTSA) has decided to not issue a recall for some 2004-2007 Ford Freestar and 2004-2007 Mercury Monterey minivans after a year long investigation. The NHTSA started the investigation in August 2010 after receiving complaints that water could run down onto the cowling under the hood in the windshield wiper area and would drip onto the power train control module (PCM). The module would short, causing a variety of problems including stalling, poorly shifting transmission, erratic power, and a lit malfunction light. The NHTSA found that the failure rate was below what would be considered a defect trend and decided not to issue a recall. The agency will continue to monitor complaints and take further action in the future if warranted.
