2017 Jeep Grand Cherokee Trailhawk Quick Spin

Jeep won't come out and say it, but the 2017 Grand Cherokee Trailhawk exists to bloody the nose of the Toyota 4Runner TRD Pro. America's off-road brand hasn't built a wheeling-specific version of its Grand Cherokee flagship in years, and the last GC Trailhawk was mostly stickers and tires. It was time for a true trail-spec Grand Cherokee again. We took a quick spin (two of them, actually) in the latest Trailhawk model, which joins Renegades and Cherokees with the same badge and off-road bent for 2017. Our time was limited, and so were our initial findings. After driving on and off pavement at Fiat Chrysler's proving grounds in Chelsea, Michigan, we can tell you that on the road, this Grand Cherokee has the same refined driving dynamics as any other. As for off-roading, the capability is still somewhat of an open question. Driving Notes The suspension and off-road system tuning are what really set the Trailhawk apart from other Grand Cherokees. Jeep tweaked the four-corner Quadra-Lift air suspension to improve articulation and suspension travel, while retaining the 10.8 inches of ground clearance of lesser Quadra-Lift Grand Cherokees. Paired with the standard Quadra-Drive II four-wheel-drive system, rear electronic limited-slip diff, and 20-inch Goodyear Adventure off-road tires, the Trailhawk is not short on capability (at least on paper). Unfortunately, paper is almost where this stops. The Trailhawks we drove were pre-production models with unfinished software calibrations. The throttle on the 3.6-liter V6 Trailhawk we took on the off-road course was super touchy and hard to modulate, regardless of which Selec-Terrain off-road mode was selected. Without a reliable throttle, we were bounding over obstacles instead of negotiating them patiently. This was back in June, and Jeep's PR reps assured us at the time that the engineers knew about the oversensitive throttle and have since confirmed that the issue has been fixed for production models, which are rolling off the line in Detroit now. We're planning to get into one of those vehicles as soon as one becomes available for a full review. Like the standard model, the Trailhawk's air suspension offers more comfort than the double-wishbone front and four-link rear suspension on the 4Runner.

2014 Jeep Cherokee: Introduction

When we look back at some of the more shocking product launches of recent yeras, the Jeep Cherokee is certainly high up on the list. And we aren't just talking about its off-the-wall, polarizing design.
For starters, it brought back the iconic Cherokee nameplate - something Jeep enthusiasts have coveted for ages. But beyond that, it brought a new evolution for the Jeep brand. After all, the Cherokee is car-based - using the same compact platform that underpins the Dodge Dart and Chrysler 200. It has a greater focus on technology and refinement than ever before, in an effort to appeal to a new crop of Jeep customers. And powering it all is a new (optional) V6 engine paired with an equally new nine-speed automatic transmission.
Can the Cherokee's car-based roots still allow for a vehicle that's superb when the going gets tough? Will its design still be a love/hate affair in one year's time, or will it start to blend in? Is the powertrain strong enough to not only support the needs of daily driving and road trips, but blaze a few trails as well? We're aiming to answer all these questions, and more, over the next 12 months. Welcome to the Autoblog long-term garage, Cherokee.

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.

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.
