Chrysler recalling 644k more Dodge Durango and Jeep Grand Cherokee SUVs over brakes

Early last month, we reported on Chrysler issuing a preemptive, proactive recall for about 25,000 units of the Jeep Grand Cherokee and Dodge Durango. The issue revolved around a brake system that wasn't causing any actual problems, but delivered an unsatisfactory brake feel, so Auburn Hills called in a good 25,000 of SUVs around the world, including 18,700 in the United States.
Now Chrysler, having apparently determined that the brake problem on its sport utes is actually much bigger than it initially realized, has drastically broadened the scope of the recall. As a result, the National Highway Traffic Safety Administration has issued a recall for precisely 655,354 examples of the Grand Cherokee and Durango, covering the 2011 through 2014 model years. In addition, Chrysler is recalling 42,380 units in Canada, 21,376 in Mexico and 159,685 overseas.
The problem which Chrysler found revolves around the brake booster, whose center shell has been found to be subject to corrosion, allowing water to get into the brake system. That water in turn could freeze, preventing the brakes from working as well as expected.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

Dream Cruising in three Jeep concept cars

Those of you that have attended the yearly Woodward Dream Cruise, know that the rolling car show is many things to many people. A chance to pull the Corvette out of the garage; a time to ogle rare models you've never yet seen in the metal; a weekend for drinking a cold one with friends and simply taking in the festivities. But for our roving editor Brandon Turkus, this year was a chance to cruise in some concept Jeeps that most people will never see, let alone drive. As Turkus aptly points out from the start, Woodward isn't exactly Moab. But wheeling the off-roaders is nevertheless an eye-opening experience; they may not be upcoming products, but these Jeeps tease out a lot we'd like to see from the brand in the future. You can find these mini Short Cut reviews above, and below, but here's a recap of what Turkus got to drive. Jeep Wrangler Staff Car Concept This one's a proper salute to the Jeep military service vehicles of yore. It's an open-air concept based on the four-door Wrangler, with tons of heritage design cues. It looks old, but we promise, it's totally new. It's got basic steel wheels, a stretched canvas roof, bench seats, a painted steel floor, a built-in cooler that accommodates up to 85 cans, and is painted in an iconic Sandstorm color. When the going gets tough, the Staff Car can handle it with aplomb, thanks to the Jeep Performance Parts two-inch lift kit, Fox shocks, Dana 44 axles, and the Wrangler's 3.6-liter V6. Jeep Chief Concept This Wrangler-based concept is an excellent tribute to the classic, fullsize Jeep Cherokee from the 1970s. It's painted in a vintage Ocean Blue color, with a white, "French Bread" roof. There's also a custom razor grille (something made famous on the original Wagoneer), removable sides, chrome bumpers, and classic-looking, 17-inch wheels. Inside, there's surfer-inspired pink, blue, and white cloth mixed with leather trim, with more fun details like a Rosewood front passenger grab handle and tiki-look shift handle. Of course, this thing looks to be truly capable off-road, too, with a two-inch lift kit, Fox shocks, Dana 44 axles at the front and rear, and a 3.6-liter Pentastar V6 underhood. Jeep Wrangler Africa A take on the Wrangler Unlimited, painted in Desert Tan, and powered by a 2.8-liter diesel engine. It looks killer, with 17-inch, body-colored steel wheels wrapped in 35-inch BF Goodrich Mud Terrain tires. There's a two-inch lift kit, Dana 44 axles, and Fox shocks.
