Feds chastise Marchionne over Jeep recall, only 13% repaired so far

Following the significant outcry surrounding the General Motors and Takata airbag safety crises this year, the National Highway Traffic Safety Administration seems to be taking a much more aggressive role in pushing owners to repair their recalled vehicles. In the agency's latest move, it's urging Jeep drivers to get their models fixed. Acting NHTSA administrator David Friedman even sent a letter to Fiat Chrysler Automobiles CEO Sergio Marchionne pressing him to get more of the SUVs fixed. The problem goes back to the recall of the 2002-2007 Liberty and 1993-1998 Grand Cherokee because of the possibility for the fuel tank to rupture in some rear crashes. The campaign affected over 1.5 million vehicles, but Chrysler initially refused NHTSA's request for a repair campaign. The automaker eventually came up with a fix that involved adding a trailer hitch to provide extra protection to the tank. The feds believe the danger "will be reduced by the remedy now offered by Chrysler," according to the statement. However, this latest push comes out of NHTSA's concern that only three percent of the affected vehicles are repaired, although Chrysler maintains some 13.4 percent have actually been fixed. The agency is asking the automaker to reach out to owners "proactively," and get them to bring the Jeeps in dealers. According to the the feds' statement, the company "has nearly 400,000 parts available" to perform the fixes, and it's still producing more. Friedman's letter to Marchionne goes even further, alleging NHTSA has received reports that dealers are turning customers away who request the recall. He asks the CEO to prove within 15 days that these claims are false. "Given the low rates of repair that Chrysler has reported more than a year after the recall, significantly more aggressive steps are required," says a portion of the note. According to The Detroit News, Chrysler has subsequently promised to speed up the recall work, vowing that all dealers will have at least 12 repair kits in stock by Monday. Further, it has announced plans to ramp up its notification campaign with Facebook ads and public service announcements.

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.

2016 Jeep Wrangler to ditch solid axles to save weight?

Hey, Jeep fans. If you think the idea of a funky-looking, car-based Cherokee revival is offensive, have a listen to what might be in store for the next-gen Jeep Wrangler. Automotive News is reporting that as Jeep develops the 2016 Wrangler, weight reduction is a crucial target, and the Wrangler's rugged solid axles could be sacrificed in the name of better fuel economy.
We've already heard the next Wrangler will go on a serious diet using aluminum body panels and an air suspension system, so the idea of a four-wheel independent suspension setup for this OG SUV isn't all that surprising. Besides, it's not like an independent suspension would limit the Wrangler's off-road abilities - just check out the Hummer H1. In fact, it might be the aftermarket parts companies - not Wrangler enthusiasts - who would be most disappointed by such a drastic suspension change, as the article states that the Wrangler's solid axles and coil-link suspension make it the most popular SUV for customization.
There are probably still a couple years before we'll start hearing any concrete details about the 2016 Wrangler, at which time it will be interesting to see how stricter fuel economy and crash safety regulations have been balanced with traditional Wrangler cues like its removable doors and roof and folding windshield. Let us know in the comments below if a Wrangler sans solid axles is any less of a Wrangler.
