FCA issuing software update for 1.4M vehicles to prevent hacking

In the wake of a Jeep Cherokee being hacked remotely while on the road through its Uconnect infotainment system, FCA US is now issuing a software update for 1.4 million vehicles in the United States. Affected customers will receive a USB stick in the mail with the improved version; owners can check this website to see if their cars are affected. A large variety of models with FCA's 8.4-inch touchscreen infotainment system are affected. They include the 2015 Chrysler 200, 2015 Chrysler 300, 2015 Dodge Charger, and 2015 Dodge Challenger; 2013-2015 Dodge Viper; 2013-2015 Ram 1500, 2500, and 3500; 2013-2015 Ram 3500, 4500, and 5500 chassis cab; 2014-2015 Jeep Grand Cherokee and Cherokee; and 2014-2015 Dodge Durango. According to FCA in its announcement, the new software "insulates connected vehicles from remote manipulation." As of July 23, the company also "fully tested and implemented within the cellular network" additional security to prevent access to many of a vehicle's systems. FCA US says that it's conducting this campaign out of an abundance of caution and disputes the notion that there's a defect with these vehicles. Beyond the demonstration of the hack in the Cherokee, the automaker says that it's unaware of any other reports of these attacks actually happening. Related Video: Statement: Software Update July 24, 2015 , Auburn Hills, Mich. - FCA US LLC is conducting a voluntary safety recall to update software in approximately 1,400,000 U.S. vehicles equipped with certain radios. The recall aligns with an ongoing software distribution that insulates connected vehicles from remote manipulation, which, if unauthorized, constitutes criminal action. Further, FCA US has applied network-level security measures to prevent the type of remote manipulation demonstrated in a recent media report. These measures – which required no customer or dealer actions – block remote access to certain vehicle systems and were fully tested and implemented within the cellular network on July 23, 2015. The Company is unaware of any injuries related to software exploitation, nor is it aware of any related complaints, warranty claims or accidents – independent of the media demonstration.

Chrysler Recalls Jeep SUVs For Ignition Switches

The ignition switch defects that engulfed General Motors are now a rapidly growing problem at Chrysler. Chrysler said Tuesday it is recalling up to 792,300 older Jeep SUVs worldwide because the ignition switches could fall out of the "run" position, shutting off the engine and disabling air bags as well as power-assisted steering and braking. That's the same problem that has forced GM to recall more than 15 million cars over the last six months. Chrysler's recall covers 2005-2007 Grand Cherokees and 2006-2007 Commanders. The company said it is not sure exactly how many will be recalled, but said it will notify customers by mid-September. Chrysler said an outside force such as a driver's knee can knock switches out of the "run" position. Engineers are working on a fix. The Auburn Hills, Michigan-based automaker, now part of Fiat Chrysler Automobiles NV, said it knows of no related injuries and only one accident. But it said owners should keep clearance between their knees and keys until repairs are made. Chrysler has now recalled more than 1.7 million vehicles for ignition-switch problems. In June, the company added 696,000 minivans and SUVs to a 2011 recall to fix faulty ignition switches. Those recalls covered Dodge Journey SUVs and Chrysler Town & Country, Dodge Caravan and Volkswagen Routan minivans - which Chrysler made for the German automaker - from the 2007 to 2010 model years. Tuesday's recall is the outgrowth of two investigations opened by U.S. safety regulators last month as part of a broader probe into ignition-switch and air-bag problems across the auto industry. The agency wouldn't say Tuesday whether its investigation could lead to recalls at other automakers. The National Highway Traffic Safety Administration said in June that it was investigating Jeep Commanders and Grand Cherokees after getting 32 complaints that a driver's knee can hit the key fob or key chain, causing the ignition switch to move out of position. The federal investigation is still open. The agency said Tuesday that it is requesting additional information from Chrysler to ensure that its repairs will be effective. The investigations and recalls come after GM bungled an ignition-switch recall of older small cars. GM acknowledged that it knew of the ignition problem for more than a decade but failed to recall the cars until earlier this year, when it recalled 2.6 million small cars such as the Chevrolet Cobalt.

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.
