Buy this instead of a Wrangler | 2017 Jeep Grand Cherokee Trailhawk Review

In our first encounter with the 2017 Jeep Grand Cherokee Trailhawk at Fiat Chrysler's Chelsea Proving Grounds, we saluted the new model's impressive on-road demeanor. In its off-road mode, however, we couldn't ignore the pre-production throttle calibration – it was super sharp and difficult to modulate with the precision needed to navigate obstacles. We were told then that Jeep's engineers were aware of the problem and were fixing it for production models. So we recently set off for Bundy Hill Off-Road Park in Jerome, Michigan, in a production-spec Grand Cherokee Trailhawk to check their work and get a better idea of the overall package. We can report that the Trailhawk's throttle has been fixed for production, landing it properly in Goldilocks territory. In the off-road Mud setting, the throttle is soft and easy to modulate. You can balance this rig with the gas pedal, reaching just past tip-in to steadily prod forward. But the gas pedal doesn't delay when you really need power. Move beyond the initial tip-in, and the engine responds quickly, which is a good thing, as a sluggish throttle is almost as dangerous off-road as one that's too sharp. Rock mode promises even more precise control over the throttle, although our lack of a spotter and a desire to avoid damaging the 700-mile-young Trailhawk kept us from hitting Bundy Hill's rockier sections. The wet, non-snowy weather meant we didn't properly test Snow or Sand mode. This test model was equipped with FCA's popular 3.6-liter V6, but like the rest of the Grand Cherokee range, more power is available from the 3.0-liter EcoDiesel V6 and the 5.7-liter Hemi V8. You don't need them – the 3.6-liter and eight-speed automatic are perfectly fine on the trails. Faced with an incline, the transmission holds its gear without complaint – you don't even need to switch into manual mode. Despite the 4,800-rpm torque peak, the V6's 260 pound-feet arrive early enough that you don't need to strong-arm the throttle. So that's resolution for the pre-production issue. But our time at Bundy Hill exposed a different and ultimately much easier to fix problem for the production model. Late fall in Michigan is not always a good time to go off-road – sub-40-degree temperatures and a steady, depressing drizzle can turn a relatively simple trail into a slippery mess of wet clay. Conditions like these can easily overwhelm an on-road tire like the Goodyear All-Terrain Adventures the Trailhawk uses.

Jeep Wrangler Polar Edition coming to America

Jeep originally took the wraps off its Polar Edition Wrangler at the Frankfurt Motor Show in September, and at the time, we figured this would be a Europe-only affair. (Perfectly fine, since we US customers haven't exactly been lacking special edition Wrangler models over the years.) But now, and as Jeep says, just in time for winter, the automaker has announced that the ice cold Wrangler will be hitting North American showrooms in November.
Based on the Wrangler Sahara model, the Polar Edition can be had in either two- or four-door body styles, with a unique Hydro Blue paint job as the featured color. (Buyers can also opt for less-special Billet Silver and Bright White hues.) Other exterior enhancements include a body-colored hardtop, 18-inch gloss black wheels, the Powerdome (power bulge) hood, and unique decals all around the body.
But the Polar Edition isn't just about some paint and stickers. Jeep has fitted this Wrangler with a Dana 30 front axle and Dan 44 rear axle, as well as the Trac-Lok anti-spin electronic rear differential. Like all US-spec Wranglers, the Polar Edition uses Jeep's 3.6-liter Pentastar V6, producing 285 horsepower and 260 pound-feet of torque. Both a six-speed manual and five-speed automatic transmission are available.

How to update and secure a vulnerable Chrysler Uconnect system

If you own one of the 1.4 million vehicles affected by the recent Chrysler software recall, you may want to watch this video. In it, we explain how to get the latest infotainment software loaded onto the 8.4-inch Uconnect system. The recall was a response to the findings of researchers who were able to hack into and remotely control a 2014 Jeep Cherokee through its cellular connection. Although Fiat Chrysler has worked with Sprint to plug most of the holes on the carrier side, there are still some vulnerabilities that only this latest software version can patch. Owners have three options to get the update: download it now, wait for a USB stick in the mail, or take the vehicle to an FCA dealer. Chrysler will be sending USB sticks loaded with the software update to customers. Anyone with an internet connection and a USB stick of their own with at least 4 GB capacity can speed things up by downloading the patch from the Uconnect website. We cover that process from start to finish in the video, with the final portion still applicable to those using the FCA-supplied USB stick. If after watching this you still don't want to tackle the patch yourself, you can take your vehicle to the dealer to have it done. Also note that this process is the same for all Uconnect updates, not just the one patching the exploits. Our demonstrator vehicle is a 2015 Ram 1500 pickup. The procedure should be very similar on other products with the 8.4-inch Uconnect system, with only the location of the USB port varying. Once you have the USB stick with the software on it – either after having downloaded it yourself or receiving it in the mail from Chrysler – the installation process is relatively simple. It takes about 15 minutes to perform the update; we edited out the wait in the video. To check whether or not your car's 8.4-inch Uconnect system is running the latest software, go to System Information on the touch screen's Settings page and look at Software Version. The update related to the recall is version 15.17.5. Related Video: Recalls Chrysler Dodge Jeep RAM Safety Technology Infotainment Videos Original Video hacking
