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.

Chrysler to accelerate production of 2013 Ram and V6 engines

Chrysler is adding a third shift at its Warren Truck plant to meet demand for the new 2013 Ram pickup. And with tight supplies of its Pentastar V6, the company is also boosting output at its Mack Engine plant.
The expansions will add 1,250 jobs and are part of a $238 million investment by Chrysler in the Detroit area. Warren's third shift will begin work sometime in the spring, a Chrysler rep told Automotive News. Mack's increased Pentastar production a could include both 3.6 and 3.2-liter engines.
The company says it also plans to invest $40 million in its Trenton Engine plant to allow for production of a 3.2-liter V6 as well as the Tigershark inline-four for the upcoming Jeep Liberty replacement.

Jeep reveals annual Moab Easter Jeep Safari concepts

Jeep has unveiled its annual spate of concepts before the Easter Jeep Safari. Those start with the Grand Cherokee Trailhawk Concept (below left), complete with the company's EcoDiesel V6 engine. Designers threw in a set of 35-inch Mickey Thompson tires wrapped around 17-inch Rubicon wheels, and a set of custom fender flares help keep all that rubber under wraps.
Meanwhile, the Wrangler Mopar Recon (below right) packs a 6.4-liter Hemi V8 good for 470 horsepower. All that grunt gets to the ground via a five-speed automatic transmission and a set of a Dana 60 axles frond and rear with 4.10 gears. The Recon also makes use of a 4.5-inch prototype long-arm kit and a set of prototype eight-lug bead lock wheels.
The Wrangler Stitch (below left) builds on the momentum of the Wrangler Pork Chop Concept. Engineers once again set out to strike as much weight as possible from the vehicle, and actually managed to trim the curb weight down to 3,000 pounds. That effort has given the machine the same power to weight ratio as the Grand Cherokee SRT8. Plenty of carbon fiber, door deletes and a chrome moly roll cage all help trim those pounds, and a set of DanyTrac Pro Rock 44 axles with 4.88 gears and ARB lockers front and rear let this machine scramble over whatever is in its path.
