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.

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.

2018 Jeep Wrangler to get 8-speed auto

Remember when the Jeep Wrangler had a three-speed automatic? That wasn't that long ago – as recent as the 2007 redesign – but Chrysler is keen to leave those days behind on the dusty trail. The current model ushered in a four-speed, then a five-speed, but the latest intel indicates that an eight-speed automatic is in the cards. According to a report filed with the Securities and Exchange Commission, and cited by Automotive News, Jeep plans on fitting its eight-speed automatic transmission to the next-generation Wrangler. Chrysler already uses the ZF-sourced slushbox on the Jeep Grand Cherokee, Ram 1500, Chrysler 300, and versions of the Dodge Challenger, Charger and Durango. But according to the SEC filing, the Auburn Hills automaker intends "to use this transmission in all of our rear-wheel-drive vehicles, except for heavy-duty versions of the Ram pick-up truck and the SRT Viper." AN says that Chrysler wanted to slot the transmission straight into the current Wrangler, but it wouldn't fit. Between the transmission and shift to aluminum construction, the next-generation Wrangler promises to deliver a significant reduction in fuel consumption. In correspondence with Autoblog, however, company spokesmen declined to comment on the eight-speed's suitability towards either the current Wrangler or the upcoming one.
