NHTSA closes Ford F-150 EcoBoost acceleration probe

Typically when we report on the findings of an investigation from the National Highway Traffic Safety Administration, it's because the government body has discovered a safety issue and prescribed a recall. In this case, however, NHTSA has closed an investigation into a reported performance deficit without ever getting to the recall stage.
The issue revolves around the Ford F-150 - specifically those equipped with the 3.5-liter EcoBoost engine - of which some 360,000 were built in the 2011, 2012 and 2013 model years. After receiving an initial 95 complaints, NHTSA opened an investigation last May - almost a year ago - into the reported issue of reduced engine power under hard acceleration. The agency has since received a total of 525 such complaints, and Ford itself reported receiving over 4,000.
Together, NHTSA and Ford determined that the problem resulted from cylinders misfiring, an issue itself stemming from water getting into the charge air cooler (CAC) mated to the turbochargers. In particularly humid or rainy conditions, water was found to get into the CAC, causing some of the cylinders to misfire, which in turn triggered the ECU to disable those cylinders in order to protect the catalytic converter from damage.

Ford F-150 EcoBoost in NHTSA probe for acceleration issue

According to Automotive News, the National Highway Traffic Safety Administration is launching a probe into 400,000 Ford F-150 models over possible acceleration problems. According to the article, NHTSA has received 95 reports "alleging incidents of reduced engine power during hard accelerations" on 2011 to 2013 F-150 models equipped with the company's 3.5-liter EcoBoost V6 engine.
Automotive News reports that Ford has issued three technical service bulletins "related to intermittent stumble/misfire on acceleration from highway cruise in humid or damp conditions," according to the government agency's documents. About one third of the 95 reports NHTSA has received cited humid or rainy conditions when these problems allegedly occurred.
These technical service bulletins have allowed dealers to address a "condition related to moisture accumulation in the charge air cooler during extended highway cruising at constant throttle in humid or damp conditions," AN reports, citing NHTSA documents. Furthermore, the TSB outlines details for "reprogramming the powertrain control module with the latest calibration and installing a new CAC and air deflector plate."

2015 Ford Focus gets more Aston-y [w/video]

With more and more members of the Ford brand adopting a new familial face, the Focus has been left looking like an odd man out. At the Geneva Auto Show, though, it properly rejoined the family, adopting the now familiar Aston Martin-ish grille that's proliferated throughout the range.
Overall, we're liking the refreshed Focus' look. Aside from the new grille, the headlights have been restyled and now look like elongated versions of the lamps on the Focus ST. Functionally, those headlamps are bi-xenon units, complete with an adaptive front lighting system. Out back, the rear retains the same overall look, which has been smoothed out for 2015.
In the cabin, the second-generation of Ford's much-maligned Sync system makes its debut. Sync 2, as it's called, is supposedly more intuitive than the first-gen system. Ford is promising "one-shot" navigation functions for the system. Saying "I'm hungry," should bring up a list of nearby restaurants. Of course, we'll be reserving final judgment until we can test the new system in person.
