The National Highway Traffic and Safety Administration has officially closed its investigation into the more than 500 reports of Ford's F-150 EcoBoost V-6 engines stalling under certain conditions. According to the Detroit News, the investigation looked at 2011 to 2013 model F-150s that were reported to misfire due to moisture accumulating through the intake process.
The specific conditions necessary for the reduced power situation to occur have been addressed with several intake and air cooler modifications. Ford issued a technical service bulletin to dealers that addresses how to deal with it. The fix includes the installation of a small deflector shield in the air stream. The 2014 F-150 has the fix. No word as to what effect this will have on any pending or future litigation.
No doubt NHTSA will be ramping up its recall review procedures given how much exposure it has incurred with the GM ignition recalls and the role the government safety review board played in the delayed recall.
