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.

Amazon is showcasing its big push into cars and transportation at CES

From making cars talk using Alexa's voice to managing data from factories full of robots, Amazon wants a big piece of the action in transportation, and next week at CES will unveil more about its strategy to achieve that goal than ever before. The Seattle retail and cloud services powerhouse plans to use the annual technology show in Las Vegas to unveil its plan to be a major player in self-driving vehicle technology, connected cars, electric vehicles and management of the torrents of data generated by automakers and drivers, company executives told Reuters. Amazon Web Services, which provides large-scale cloud computing and data management services, is central to Amazon's strategy. "We really are extending ourselves more and more out in the ecosystem from manufacturing to connected car," Jon Allen, head of professional services in Amazon Web Services' automotive practice, said in a telephone interview. "The takeaway message on this is if you go to CES this year we really are taking it as a 'One Amazon' view." Until now, Amazon has shown its transportation strategy to investors — and rivals — one piece at a time. Amazon has invested in self-driving software startup Aurora. It also has signed deals with automakers to deliver packages to vehicle trunks, help develop electric vehicle charging networks and use AWS to network their factories. The Seattle company will share the CES stage with partners such as virtual reality firm ZeroLight, electric vehicle startup Rivian, Canada's BlackBerry Ltd and video game software development company Unity Technologies. "It's our attempt to weave everything together in a single experience for our customers," Dean Phillips, AWS' automotive technical leader, told Reuters. "Customers don't distinguish AWS from Alexa from Amazon.com. It's Amazon."   Related: As GM readies Alexa convenience for vehicles, we ponder its dark side   At CES, ZeroLight and GM's Cadillac will demonstrate how they are partnering to develop an online vehicle configuration experience that will allow high-fidelity images of vehicles that consumers build online to be taken with them on visits to dealers, Phillips said. The process can open the door to dealers better meeting customer needs by knowing what users focused on when building their dream car. It has already boosted profit per vehicle at Volkswagen's Audi brand by an estimated 1,200 euros ($1,340), he said.

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.
