The National Highway Traffic Safety Administration (NHTSA) has opened a preliminary investigation on 2011-2013 model year Ford F-150 pickups for reported acceleration issues.
A total of 400,000 F-150s are under investigation after NHTSA has received 95 reports of incidents of reduced engine power under hard acceleration. The affected F-150s under investigation are equipped with the American automaker’s 3.5-liter, turbocharged engine.
Ford has already issued three technical service bulletins related to intermittent stumble and misfire on acceleration from highway cruise in humid or damp conditions for its 2011-2012 Ford F-150s equipped with the 3.5-liter GTDI engine. One-third of the reports NHTSA received were in humid or rainy conditions.
No crashes or accidents have been reported related to the issue.
