Ford sued over alleged 3.5-liter EcoBoost defects

Three Ford owners from Ohio have filed a lawsuit against the automaker over defects that they allege exist within the company's twin-turbocharged 3.5-liter V6 EcoBoost engine. Automotive News reports that the lawsuit claims the engine "contained serious latent design, manufacturing, or assembly defects." Those defects, the suit claims, cause the vehicle to shake, misfire and lose power quickly.
Two of the plaintiffs, a married couple, own a 2010 Ford Taurus SHO, and allege they experienced a loss of power and stalling, while the third, an F-150 owner, claims he lost power while accelerating. In addition to the Taurus SHO and F-150, the 3.5-liter V6 EcoBoost engine is also available in the Ford Flex, Explorer Sport and Lincoln MKT and MKS. Other three- and four-cylinder EcoBoost engines are not included in the suit. There have been no recalls associated with 3.5-liter V6 engine, and the National Highway Traffic Safety Administration is currently not investigating the matter.
The plaintiffs, however, claim Ford has known about the problem, citing several technical service bulletins issued to dealers of the F-150 that suggest possible fixes. Ford had no comment for Automotive News, saying that it's yet to review the lawsuit, which was filed last Friday in Columbus, OH.

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."

Aluminum lightweighting does, in fact, save fuel

When the best-selling US truck sheds the equivalent weight of three football fullbacks by shifting to aluminum, folks start paying attention. Oak Ridge National Laboratory took a closer look at whether the reduced fuel consumption from a lighter aluminum body makes up for the fact that producing aluminum is far more energy intensive than steel. And the results of the study are pretty encouraging. In a nutshell, the energy needed to produce a vehicle's raw materials accounts for about 10 percent of a typical vehicle's carbon footprint during its total lifecycle, and that number is up from six percent because of advancements in fuel economy (fuel use is down to about 68 percent of total emissions from about 75 percent). Still, even with that higher material-extraction share, the fuel-efficiency gains from aluminum compared to steel will offset the additional vehicle-extraction energy in just 12,000 miles of driving, according to the study. That means that, from an environmental standpoint, aluminum vehicles are playing with the house's money after just one year on the road. Aluminum-sheet construction got topical real quickly earlier this year when Ford said the 2015 F-150 pickup truck would go to a 93-percent aluminum body construction. In addition to aluminum being less corrosive than steel, that change caused the F-150 to shed 700 pounds from its curb weight. And it looks like the Explorer and Expedition SUVs may go on an aluminum diet next. Take a look at SAE International's synopsis of the Oak Ridge Lab's study below. Life Cycle Energy and Environmental Assessment of Aluminum-Intensive Vehicle Design Advanced lightweight materials are increasingly being incorporated into new vehicle designs by automakers to enhance performance and assist in complying with increasing requirements of corporate average fuel economy standards. To assess the primary energy and carbon dioxide equivalent (CO2e) implications of vehicle designs utilizing these materials, this study examines the potential life cycle impacts of two lightweight material alternative vehicle designs, i.e., steel and aluminum of a typical passenger vehicle operated today in North America. LCA for three common alternative lightweight vehicle designs are evaluated: current production ("Baseline"), an advanced high strength steel and aluminum design ("LWSV"), and an aluminum-intensive design (AIV).
