NHTSA closes investigation into Jeep Liberty fires

The investigation that the National Highway Traffic Safety Administration opened into the Jeep Liberty in October 2013 has been closed. NHTSA received two (!) complaints about fires starting in the driver's door, thought to be caused by the master power window switch. The initial estimate was that 80,000 Libertys could be roped into a possible recall, but according to a report in the Detroit News the agency examined records for 425,000 Chrysler products that used the same window switch, including the Dodge Nitro and Chrysler Town & Country minivan.
After canvassing 265 warranty claims related to the master switches, NHTSA concluded that the rate of fires compared to the "large population of vehicles" was rather low, and that there was no trend pattern behind the few issues it did find. Perhaps with that, and the closure of the trailer hitch investigation, the Liberty can finally rest in peace.

Chrysler 3.0L EcoDiesel V6: Autoblog Technology of the Year finalist

Offering a diesel engine in an American pickup is anything but new - Ford, General Motors and Chrysler all offer excellent and almost impossibly powerful oil-burning engines in their various fullsize trucks. What is new and novel about the 3.0L EcoDiesel, though, is its size, and the variety of vehicles that use it. It's the smallest engine, as far as displacement is concerned, currently offered in a large truck in the US, and, for 2014 and 2015, it is available in the Ram 1500 and the Jeep Grand Cherokee.
Though it may be small, it's got muscle. While 240 horsepower isn't particularly impressive these days, the engine's 420 pound-feet of torque more than makes up for that. The torque rating is even greater force than even the big 5.7-liter Hemi can muster. Chrysler's well-regarded eight-speed automatic transmission makes the most of all that bull-headed pulling power in both the Ram and Grand Cherokee. Chrysler claims the Ram EcoDiesel 1500 can tow as much as 9,200 pounds when properly equipped, which makes it "90-percent of the Hemi with a night and day difference in fuel economy."
Make no mistake; it's that promise of a sizable fuel economy improvement that many long-haul truckers will be most interested in. In the Ram 1500 that we tested for our Tech of the Year competition, the diesel engine costs $2,850 more than the gas-fed V8, and Ram estimates that EcoDiesel buyers will pay off their investment when compared to the Hemi engine in less than three years, which is considerably less time than the 4.5 or so years the average buyer will keep his or her fullsize pickup. The more you drive, the more you'll save, and the math proves equally as effective in the Jeep Grand Cherokee.

2014 Jeep Cherokee musters 22 MPG city, 31 highway

Production and media drive delays included, there has been no lack of press surrounding the 2014 Jeep Cherokee. With the most recent delay reportedly due to powertrain calibrations, we've been waiting to see how the Cherokee's fuel economy looks against the highly competitive compact CUV segment. Thanks to the EPA, we now know the fuel economy figures for the newest member of the Jeep family.
Arguably, the Cherokee has the most modern powertrain in its class with an updated base engine, all-new V6 and all-new nine-speed automatic transmission, but its fuel economy figures are simply on par for the segment. Still nothing to scoff at, though. According to fueleconomy.gov, front-wheel-drive Cherokee models with the base four-cylinder mill will top out the lineup with 22 miles per gallon in the city and 31 mpg on the highway; opting for four-wheel drive with this engine drops the figures to 21 city and 28 highway. Get even crazier with the option list, and the new 3.2-liter Pentastar V6 will get you 19 mpg city and 28 mpg highway in two-wheel-drive form or 19 city and 27 highway for 4WD.
If you're wondering how that stacks up among compact CUVs, head on over to Automobile Magazine for a full fuel economy breakdown for the segment. The controversially styled crossover hits dealers this month, and we'll be driving it in just a couple of weeks.
