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.

NHTSA investigating Ford's solution to May 2014 power steering recall

The National Highway Traffic Safety Administration is investigating a complaint that Ford's response to a May 2014 recall of the 2008 to 2011 Ford Escape and Mercury Mariner doesn't quite go far enough to solve a troubling power-steering problem. Roughly a year ago, Ford recalled nearly a million vehicles after it was found that a problem with the torque sensor's communication with the power steering control module could cut steering assistance for drivers. While manual steering would still be available, the problem was enough to ask drivers to report in to have the PSCM inspected, and if necessary, replaced (along with the torque sensor, or in dramatic cases, the entire steering column). That would only happen, though, if trouble codes were being thrown. If there weren't any problems, dealers were told to simply update the PSCM's software so that any issues between it and the torque sensor would simply throw a visual and audio warning – power steering would still be maintained. The petitioner claimed that following the recall work, he still experienced a problem with the torque sensor. According to NHTSA, a claim was made that Ford didn't go far enough in its solution to the problem, and that "the software update itself may in fact cause further issues with the affected vehicle's power steering, causing it to fail, and ultimately requiring replacement of the torque sensor or entire steering column." The petition was filed in early February and is now officially being looked into by NHTSA.

NHTSA closes rollaway investigation into 1.56M Ford SUVs

It's taken four years of study, but the National Highway Traffic Safety Administration has finally closed the books on its investigation into rollaway accusations surrounding 1.56-million Ford SUV models.
The probe, which centered on the 2002-2005 Ford Explorer, 2002-2005 Mercury Mountaineer and 2003-2005 Lincoln Aviator, ends without the federal agency calling for a recall. According to The Detroit News, the investigation was closed due to a "low number of complaints" - NHTSA documented 180 such complaints that resulted in 14 crashes and six minor injuries, but the number of incidents have been slowing. The suspected defect rate for the trucks' automatic transmissions was found to be 4.4 per 100,000 units, and the brake-shift interlock mechanism failure rate was judged to be even lower at 3.4 per 100k.
