Feds fretting over remote hack of Jeep Cherokee

A cyber-security gap that allowed for the remote hacking of a Jeep Cherokee has federal officials concerned. An associate administrator with the National Highway Traffic Safety Administration said Thursday that news of the breach conducted by researchers Chris Valasek and Charlie Miller had "floated around the entire federal government." "The Homeland Security folks sent out broadcasts that, 'Here's an issue that needs to be addressed,'" said Nathaniel Beuse, an associate administrator with the National Highway Traffic Safety Administration. Valasek and Miller commandeered remote control of the Cherokee through a security flaw in the cellular connection to the car's Uconnect infotainment system. From his Pittsburgh home, Valasek manipulated critical safety inputs, such as transmission function, on Miller's Jeep as he drove along a highway near St. Louis, MO. The scope of the remote breach is believed to be the first of its kind. The prominent cyber-security researchers needed no prior access to the vehicle to perform the hack, and the scope of the remote breach is believed to be the first of its kind. A NHTSA spokesperson said the agency's cyber-security staff members are "putting their expertise to work assessing this threat and the response, and we will take action if we determine it's necessary to protect safety." A Homeland Security spokesperson referred questions about the hack to Chrysler. Fiat Chrysler Automobiles has already been the subject of a federal hearing this month, in which officials scrutinized whether the company had adequately fixed recalled vehicles and repeatedly failed to notify the government about defects. But cyber-security concerns are a new and different species for the regulatory agency. Only hours before the Jeep hack was announced by Wired magazine earlier this week, NHTSA administrator Dr. Mark Rosekind said hacking vulnerabilities were a threat to privacy, safety, and the public's trust with new connected and autonomous technologies that allow vehicles to communicate. NHTSA outlined its response to the cyber-security challenges facing the industry in a report issued Tuesday. In it, the agency summarized its best practices for thwarting attacks and said it will analyze possible real-time infiltration responses. But the agency's ability to handle hackers may only go so far.

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.

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000. Rank Make & Model Powertrain Green Score MSRP Estimated Annual Fuel Cost* 1 Mercedes-Benz AMG G63 Gas 20 $184,000 $4,242 2 Ram 1500 TRX 4x4 Gas 22 $98,335 $3,819 3 Ford F150 Raptor R Gas 24 $79,975 $3,777 4 Cadillac Escalade V Gas 26 $152,295 $3,388 5 Dodge Durango SRT Gas 26 $74,995 $3,332 6 Jeep Wrangler 4dr 4X4 Gas 27 $35,895 $3,260 7 Jeep Grand Wagoneer 4x4 Gas 28 $91,945 $3,058 8 Mercedes-Benz G550 Gas 28 $143,000 $3,186 9 GMC Hummer EV SUV EV 29 $98,845 $1,746 10 GMC Sierra Gas 29 $37,700 $3,069 11 Chevrolet Corvette Z06 Gas 30 $114,395 $3,169 12 Mercedes-Benz Maybach S680 Gas 30 $234,300 $3,031 *ACEEE analysis using EIA data of the annual cost of driving 15,000 miles In terms of numbers, the dirty dozen of the meanest includes seven SUVs and three trucks. Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid
