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.

Chrysler recalling 31k SUVs and vans

Chrysler is issuing recalls covering roughly 31,700 vehicles worldwide due to two separate problems. In both cases the company believes that most of the affected vehicles are either still on, or in transit to, dealer lots.
One recall covers roughly 10,700 Dodge Durango, Jeep Cherokee, Grand Cherokee and Grand Cherokee SRT models from the 2014 model year built between January 16 and April 17, 2014. The SUVs need a software update for the cruise control. It's possible that when the cruise is on and the driver presses on the throttle, the acceleration could last a second after the pedal is released or two seconds for the SRT. Afterward, they return to the speed originally set by the driver.
Chrysler says it isn't aware of any accidents, injuries or even reported incidents of this happening in the real world. Also, in all cases, if the driver presses on the brake, the cruise shuts off. The automaker believes that there are about 6,100 affected SUVs in the US, 950 in Canada, 425 in Mexico and 3,200 outside of North America. The software upgrade will be ready shortly, the company says.
