WASHINGTON — The National Highway Traffic Safety Administration has opened an investigation into an estimated 400,000 2011'-13 Ford F-150 pickup trucks after consumer complaints of possible acceleration problems.

NHTSA said it has received 95 reports "alleging incidents of reduced engine power during hard accelerations" on trucks equipped with the 3.5-liter gasoline turbocharged direct injection EcoBoost engines.

Ford told Edmunds it is cooperating with the investigation.

"Complainants allege unexpected sharp reductions in engine power during hard accelerations at highway speeds, such as attempted merging or passing maneuvers," said NHTSA in its problem description.

NHTSA noted that Ford has issued three technical service bulletins related to intermittent stumble/misfire on acceleration from highway cruise in humid or damp conditions in some 2011 and 2012 F-150 vehicles equipped with 3.5-liter GTDI engines.

"Approximately one-third of the reports received indicate that the incidents occurred while driving in humid or rainy conditions," said NHTSA. "Many complaints allege safety concerns associated with overtaking vehicles."

No crashes have been reported, according to federal safety regulators.

The affected F-150s have not been recalled. NHTSA has opened a preliminary evaluation into the matter, which sometimes can lead to a vehicle recall.

Edmunds says: There's not much that owners of the affected Ford F-150s can do at this point, except to wait for federal safety regulators to finish their investigation.

    I wonder what gas they were using. The symptoms sound like a major intervention by the knock sensor system. If Ford are tying it to damp conditions I wonder about icing in the intake system.

    And no complaints about the Flex's, Explorers, SHO's, and MKS' equipped with the same engine? Hmmm.

    They should include the Ranger, I have the same issue with a 3.0 flex fuel.
