NHTSA upgrading Jeep Grand Cherokee, Dodge Durango headliner fire probe

The National Highway Traffic Safety Administration investigation into headliner fires experienced by a small number of Jeep Grand Cherokee and Dodge Durango owners has been upgraded to an engineering analysis, the step before the initiation of a recall. In August last year the investigation began with 146,000 Grand Cherokees from 2012 after three complaints were received, but a report on Edmunds says it has been expanded to include 593,299 vehicles covering the 2011-2013 model years for the Jeep and the Dodge Durango, which uses the same headliner assembly, because of possibly 52 incidents of fire.
In some of those incidents drivers have reported a burning odor, smoke or open flames that were contained to the headliner or migrated to another area of the passenger compartment. The culprit has apparently been found: NHTSA blaming an electrical short in the sun visor vanity light wiring, which is routed under the headliner and held in place by three screws. Chrysler began its own probe into the issue when it was first reported and is still looking into the situation while, "fully supporting the National Highway Traffic Safety Administration's investigation."

Watch this 650-hp Hennessey Jeep Grand Cherokee go from 0-60 in 3.9 seconds

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower - 530 hp at the wheels, according to Hennessey - and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.
There's more than just a Roots-type supercharger bolt-on, with ported cylinder heads and high-flow headers among the many changes made to the engine. You can watch this pre-2014 facelift silver model prove its spec sheet on the drag strip in the video below.

Jeep Wrangler Copper Crawler is our idea of a restrained Mopar shopping spree

According to a recent report, the Jeep Wrangler is the most popular SUV for customization, and this is backed up by the fact that the iconic off-roader was just named the Hottest 4x4-SUV at SEMA for the fourth year in a row. Looking for ways to keep its customers in-house rather than going aftermarket, Jeep and Mopar are always teaming to offer exciting new parts and pieces for the JK Wrangler.
Compared to most other Wranglers on display at SEMA - as well as other Chrysler Mopar SEMA concepts - the Jeep Wrangler Copper Crawler is surprisingly reserved, but should be no less exciting for owners to give their Wrangler a distinctive look. Starting off with an eye-catching copper paint scheme, the Jeep then goes on a Mopar catalog shopping spree with its matte black grille, black beadlock wheels, two-inch lift, Rubicon bumper (with a winch and aero end caps up front) and rocker panel and taillight guards.
Jeep also upgraded the Wrangler's transfer case for low-speed rock crawling (hence the vehicle's name) and cold-air intake for extra measure.
