NHTSA investigates a million-plus Jeep Cherokees for parking brake issue

The National Highway Transportation Safety Administration (NHTSA) is investigating a potential safety issue that could be present in more than 1 million Jeep Cherokees sold for the 2014-2020 model years. Per owner complaints, these cars may be equipped with an electronic parking brake control module that is susceptible to water intrusion. If the water causes a short, it can result in uncommanded activation of the parking brake while the vehicle is in motion, which can lead to a stall, NHTSA says.  If you follow Jeep Cherokee news closely (and who doesn't?), this issue may ring a bell. That's because Jeep was on the hook for recalling the Cherokee for water intrusion into the liftgate control module, which is fitted right next to the parking brake module. In that instance, short circuits had the potential to cause a fire, which has not so far been indicated as a potential side effect of the new parking brake issue, but any time electricity is involved, there's usually at least some risk for ignition.  The Cherokee is just one of four Stellantis models with a new open investigation, the Detroit Free Press reported Tuesday. NHTSA is also looking into reports of a transmission problem that could strand owners of 2019-2021 Chrysler Pacifica plug-in hybrid minivans and a crankshaft and/or camshaft position sensor problem that could cause a stall in the 2016 Dodge Journey and Jeep Compass. Between the two, these investigations cover an additional 300,000 vehicles.  None of these vehicles are being recalled at this point, however a NHTSA investigation is the first major step toward a recall being initiated. The regulator will work with Stellantis to determine whether a recall is necessary.  Related video: This content is hosted by a third party. To view it, please update your privacy preferences.

2018 Jeep Wrangler four-cylinder fuel economy revealed

Fuel economy numbers for the 2018 Jeep Wrangler with the turbocharged 2.0-liter four-cylinder have finally been announced by the EPA. In the city, the two-door model gets 23 mpg, and the four-door Unlimited gets 22. Highway fuel economy for the two-door is 25 mpg and 24 for the four-door. Combined for the two-door and four-door is 24 and 22 respectively. These aren't Prius numbers, but they do make the four-cylinder Wrangler the most efficient version of the off-roader so far. The rest of the Wrangler range with V6 power gets 20 mpg combined, with the exception of the manual four-door, which gets 19. The most efficient V6 models in the city are the automatic models, which, regardless of length, get 18 mpg. On the highway, the best V6 is the manual two-door, which manages 25 mpg, and only loses 1 mpg in the city to the automatic. The question is, is the improved fuel economy worth the price premium of the four-cylinder? The automatic-only four-cylinder engine is an extra $1,000 over a V6 automatic, and $3,000 over a V6 manual. And when looking at the annual fuel cost estimates at fueleconomy.gov, you might only save $50 to $100 each year. The problem being that, while it's more efficient, it also demands premium fuel that the V6 doesn't. So it could be quite a while before the upfront cost is recouped. But if you want a Wrangler that's a little nicer to the planet, it's probably the way to go, plus you get an extra 35 pound-feet of torque over the V6, even if it means sacrificing nearly 20 horsepower.

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.
