Jeep hackers return to take over your steering wheel

Last year, security researchers Charlie Miller and Chris Valasek made headlines by remotely hacking a Jeep, killing the transmission and applying the brakes while Wired reporter Andy Greenberg was behind the wheel and driving in traffic. The hack led to a 1.4 million-vehicle recall for Fiat Chrysler and new jobs at Uber's Advanced Technology Center for Miller and Valasek. Despite the cushy new gigs, the two of them apparently aren't done hacking Jeep Cherokees for sport. In their latest exploit, the pair can gain even more control over a vehicle, but it would also be extremely difficult to pull off in a real-world setting. Here's the harrowing part first: Miller and Valasek can do more than just apply the brakes at low speed or cut the transmission this time around. Now they can turn on the parking brake, mess with the cruise control and hijack the auto-parking system to jerk the steering wheel a dangerous 180 degrees while the car is in motion. It looks about as frightening as it sounds: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Although it's not hard to see how that would make for a very terrifying drive, there's a big grain of salt that comes along with it: Miller and Valasek actually used the same model 2014 Jeep Cherokee as the original demonstration, but without the software patch applied. Or, as Wired put it, "imagine an alternate reality," where a fix had never been made. Unlike before, the latest hack requires a physical connection plugging their laptop into the Jeep's OBD-II diagnostic port under the dash. The team also had to update the Jeep with their own firmware to disable some of the car's built-in safety checks before they could get much control. In other words: In order to get hacked, Jeep owners would first need to roll back their car's firmware to an older version, invite someone to remove security features and then also let them ride shotgun with a computer. Or, as Engadget's resident security expert Violet Blue wrote on Twitter, it's sort of a non-threat. This content is hosted by a third party. To view it, please update your privacy preferences.

That said, The Verge points out that it may still be possible to exploit OBD-connected wireless dongles like the Metromile Tag, Automatic Link or other similar devices currently marketed by insurance companies.

Junkyard Gem: 1983 Jeep DJ-5L Mail Dispatcher

When it comes to putting mail in boxes, a simple and reliable vehicle works best. Say, a zero-frills steel box on wheels, with right-hand-drive, a fuel-efficient four-cylinder engine, no-hassle automatic transmission, sliding doors, and a big mail-sorting table instead of a passenger seat. That's what the AM General Mail Dispatcher DJ-5 was all about, and these bouncy little trucks were everywhere for decades. Here's a late-production example, still in USPS colors, spotted in a Denver-area self-service wrecking yard. Neither snow nor rain nor heat nor gloom of night stayed this courier from the swift completion of its appointed rounds. Note the "Sonic Eagle" USPS logos on the doors; this became the official USPS logo in 1993, nearly a decade after the final Jeep DJ-5s were built. Plenty of these trucks stayed in service into our current century, and a few are still being used by private mail-delivery contractors in rural areas. During the American Motors era of Jeep DJ production (1970 through 1984), a bewildering assortment of engines went into postal Jeeps. This is a 2.5-liter GM Iron Duke four-cylinder; before that, DJ-5s came with Audi power (more or less the same engine used in the Porsche 924, in fact), AMC straight-sixes, and Chevy Nova four-cylinders. The 1984 DJ-5Ms ran the AMC 2.5-liter four-cylinder. The earliest DJs were equipped with three-speed manual transmissions, but the American Motors-built postal-delivery versions all had automatic transmissions. This one has a three-speed Chrysler Torqueflite A904, a weird engine/transmission combination that should help you stump your friends during car-trivia debates. Check out the ultra-bare-bones heater/ventilation controls! These trucks were badged as AM Generals, not Jeeps (I couldn't find a single Jeep label anywhere on this one), just like the original HMMWV. However, you'd have to be a real hair-splitter to refer to this as an AM General DJ-5 instead of just Mail Jeep or Jeep DJ-5. Next time you complain about your subcompact rental car lacking driver-comfort features, consider this vehicle. I had a few high-school friends who owned DJ-5s, back in the early 1980s when they were available for a couple hundred bucks at government-surplus auctions. The first thing civilian DJ-5 owners always did was tear out the mail-sorting table and replace it with a random junkyard bucket seat (or an aluminum lawn chair). These trucks were very noisy, very bouncy, and very slow, but they always ran.

Jeep Cherokee sales rival Wrangler after two months

In our First Drive article on the 2014 Jeep Cherokee we said, "our informal and thoroughly unscientific opinion is they're going to sell tons of them. Why? Because it is very good." So far, it appears the public concurs. Of course, it's very early - the new compact utility has logged just one month of confirmed sales, but Larry Vellequette at Automotive News says dealers have told him that the second month of sales will be even better, a message that mirrors what we've heard from company execs.
In its first, severely truncated month on sale, the Cherokee sold 579 units. With all of November to play with, though, dealers moved 10,169 of them - compared to 11,753 Wranglers and 14,798 Grand Cherokees. That helped propel Jeep to a 30-percent year-on-year improvement for the month, Chrysler Group to a 16-percent improvement and the group's 44th consecutive month of sales growth, exceeding analyst expectations in posting its best November numbers since 2007.
If it can just keep replicating the its first month of sales, the finalist in North American Truck of the Year voting will smoke the trade done by the outgoing Liberty, which didn't break 7,900 units in a month in the last four years of its life (and normally didn't get close to even that). In March this year, Chrysler said it wants to build 250,000 Cherokees in its Toledo assembly plant for global sales. It's early yet, but with second-month sales quoted as being as "strong as death," the bookies might be resetting the odds.
