NHTSA closes probes on Jeep Grand Cherokee, Ford Freestar and Mercury Monterey

The Detroit News reports the National Highway Traffic Safety Administration has officially closed its investigations into 2012 Jeep Grand Cherokee, 2004-2005 Ford Freestar and Mercury Monterey models. The separate probes found no issues that pose safety concerns. NHTSA began investigating certain Grand Cherokee SUVs over complaints that power steering hoses could detach during operation, thereby increasing the risk of a vehicle fire. Of the 24 reports of failure, none alleged smoke or fire in the engine bay, and Chrysler has since modified the power steering cooler assembly to reduce the likelihood of the failure.
Meanwhile, certain Ford Freestar and Mercury Monterey vehicles garnered a government probe after receiving complaints that the models were equipped with faulty scissor jacks. The agency had received six reports of the jacks failing or causing injuries, including one incident that resulted in a fatality. But NHTSA says the jack failure rate is similar to those found in other vehicles. In those six cases, the government agency found the jacks were being used for something other than changing a tire, and investigators could not determine whether the emergency brake was set or the rear tires were properly chocked.

Ford to show special edition Raptor on April 9

There are precious few details, but what we do know is that Ford will be revealing images of "appearance upgrades" for a special-edition 2014 F-150 SVT Raptor on April 9. The slideshow will happen during a Motor Press Guild luncheon at Ford's Design Center Showroom in Irvine, California.
Without photos or further details, we're left to wonder about the extent of these changes, but aren't expecting anything too significant given the venue. Ford is understood to be revealing a next-generation F-150 with a big weight loss - as much as 700 pounds - for 2014, though it isn't yet clear if that's the truck's model year or simply its on-sale year. For at least a couple of years, Ford forums have been suggesting changes will come with the 2014 Raptor, so there could still be a bigger surprise in store. Either way, we'll know what all this means in a little more than a week. The press release below has the official details, but for the moment, we'll content ourselves by ogling the 2013 model above.

Ford will add lots of carbon fiber to new vehicles

With BMW receiving a bunch of positive press for its usage of carbon fiber to build its i3 and i8 plug-in vehicles, Ford is jumping into that game as well. The US automaker has reached a manufacturing agreement with Dow Chemical to speed up the use of that material in Blue Oval vehicles. Carbon fiber usage will cut weight from Ford's new products, boosting fuel efficiency as a result. Ford will work with DowAksa, a 50/50 joint venture between Dow Chemical and Turkey-based Aksa Akrilik Kimya Sanayii A.S, on a manufacturing partnership. The goal is to speed up technology research to make it cheaper to make cars and trucks with carbon fiber materials. Ford's light-weighting efforts received a boost of sorts this week when its aluminum-body 2015 F-150 was awarded a five-star Overall Vehicle Score in the National Highway Traffic Safety Administration's testing, making this year's version the safest to date. The new body construction cut 700 pounds from the truck's curb weight. Take a look at Ford's press release about DowAksa below. FORD, DOWAKSA TO JOINTLY DEVELOP CARBON FIBER FOR HIGH-VOLUME AUTOMOTIVE LIGHT-WEIGHTING APPLICATIONS Ford and DowAksa formalize agreement to advance the adoption of cost-effective carbon fiber components through technology validation and proof of concept to reduce vehicle weight and increase fuel efficiency without sacrificing strength Agreement provides pathway for a high-volume manufacturing partnership New joint development agreement accelerates joint research announced in January in partnership under new U.S. composites manufacturing institute Ford and DowAksa today signed a joint development agreement (JDA) to formally advance research on cost-effective, high-volume manufacturing of automotive-grade carbon fiber, a material poised to play a significant role in the drive to make vehicles lighter for greater fuel efficiency, performance and capability. The agreement, between Ford Motor Company, Ford Global Technologies and DowAksa – a 50/50 joint venture between The Dow Chemical Company and Aksa Akrilik Kimya Sanayii A.S – will combine DowAksa's feedstock capacity, carbon fiber conversion and downstream intermediates production capabilities with Ford's expertise in design, engineering and high-volume manufacturing. The goal is to produce materials that make cost-effective carbon fiber composite parts that are much lighter than steel but meet automotive strength requirements.
