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.

How privacy fears are driving automakers in the age of the connected car [w/poll]

A recent GAO report concluded car companies don't adequately disclose how and why they share location data. As cars collect and store more and more data about the whereabouts of their drivers, automakers are responding to critics who say they should be more transparent about how those details are used. Ford is hiring a global privacy policy attorney to craft the company's customer privacy policies in the era of connected and autonomous cars. "In this emerging space, there is an important need to address customer privacy policies," reads a job description posted on the "people and careers" portion of the company's website. "As part of our compliance and ethics organization at Ford, this person will have an immediate and direct impact in shaping existing and future policy and corporate thinking in this area." Ford is creating the new position, based at its Dearborn headquarters, at a time technology advances are outpacing privacy protections. Earlier this year, a report from the federal government concluded car companies don't adequately disclose to motorists how and why they share location data. That report, from the Government Accountability Office, found many car companies did not describe how they shared location data, did not allow consumers to request their data be deleted and that there was a "wide variation" in how car companies retained vehicle-specific or identifiable location data. It noted there is increased risk of location data being used in ways "consumers did not intend." Ford was one of 10 companies the GAO surveyed while compiling its report. Customers are opting to share that data largely by using features like maps and turn-by-turn direction that are run by a vehicle's telematics unit. Depending on the company, it can be unclear how that data is collected, retained or shared. At the time the GAO report was issued, AAA, the nation's largest motoring club, urged carmakers to be more transparent in how they handle data and to offer stronger security protections. Shaping Autonomous Car Regulations At Ford, the new hire could change how the company handles that data. According to the job description, the successful applicant will, "demonstrate visionary thinking around privacy strategy – imagine how consumer and employee expectations around privacy may evolve and how business should adapt, develop approaches that maximize the benefit of data sharing for consumers and business, etc." (Emphasis from Ford).
