100,000 Jeep Cherokee models subject to further 9-speed recalibration

It seems that the software problems with the nine-speed automatic gearbox in the Jeep Cherokee continue to mount. The programming already caused multiple development delays and even postponed the Cherokee's market launch by roughly two months. Now, Jeep has issued another recalibration to hopefully assuage unhappy drivers.
According to Automotive News, this reflash for the allegedly jerky transmission covers over 100,000 Cherokees built before May 5, but it's not technically a recall. If owners are having problems and complain to the dealer, they get the new software. Otherwise, they continue with the current version. New vehicles on dealer lots also receive the latest revision to the programming. It takes only around five minutes to install, but technicians need to take the Cherokee on a test drive to adapt the gearbox to the changes.
The Cherokee's transmission software has been problematic practically since the beginning. The Jeep plant in Toledo, OH, briefly idled its second-shift workers last year to take care of the issue. Since the launch issues for the crossover, demand has been strong. Jeep added another 1,000 temporary workers to the Toledo factory to keep up, and sales were on par with the Wrangler in just its first two months.

Jeep, Ram tease SEMA builds, and one looks like a Ram 1500 TRX PHEV

SEMA is back this year, and shows no signs of cancellation. And that means a whole new crop of custom builds from not only aftermarket companies, but OEMs such as Jeep and Ram. The two brands released teasers of their modified trucks for the show, and there are a couple of seriously intriguing ones. And the most brow-raising is the silver Ram 1500 TRX that could be a plug-in hybrid. What makes us say that? Well, take a look at the badging. The "RAM" badge in the grille is bright blue. And the front tow hooks are blue, too. Those cues are signatures of the Jeep 4xe plug-in hybrid models. And Jeep isn't the only one to utilize blue badging for electrified models. Ram 1500s with the 48-volt eTorque hybrid assist get blue-highlighted badges. So it seems like a slam-dunk that the wide-bodied desert-stomper in the teaser has a hybrid powertrain. We'd bet on it being the 375-horsepower turbo-four from the Wrangler, but maybe Ram put something unique together. The next curious model is what's quite clearly a variant of the military M715 truck. It's undoubtedly this year's restomod, as Stellantis brands are wont to build. Looking closer, it has a very high roof and center-mounted spotlight. Those are cues shared with the M725 ambulance. We wouldn't be surprised if Jeep took one of the old ambulances and turned it into one beast of an overlanding rig. We're excited to see what sort of other upgrades have been done, such as what engine will be powering it. Then we come to the interior of a Jeep Wrangler Unlimited. At first glance, there doesn't seem to be much going on, at least until you look at the roof. The cargo area has a significantly raised section. And there are safari windows letting light in. It will be interesting to see what it looks like from the outside. Finally, we have teasers of what's probably a Wrangler Rubicon 4xe and a Ram 1500. The Wrangler shot is of the front fender, and the Ram is of the rear. They don't show much except what seem to be Mopar accessories. As such, we suspect these are show pieces for the Mopar catalog, and they might each have a couple of concept parts, but are otherwise a bit tame compared to the Jeep and Ram one-offs. All of these trucks will be revealed and on display at the SEMA show in Las Vegas. The show will run Nov. 2-5. Related Video: This content is hosted by a third party.

2018 Jeep Wrangler Rubicon Off-road Review | Earning our trail rating the easy way

LAKE TAHOE, Calif. — When all 4,145 pounds of Jeep slams down on the rock, the BANG! cuts the tranquility of California's Sierra Nevada mountains, echoes off the surrounding hillsides, and travels for miles through the thick unmolested forest of ancient pines. The brutality of the impact sends a shutter though the Wrangler's chassis, compresses our spines into its seat padding, and momentarily yanks my hands from its leather wrapped steering wheel. Then comes the high-pitch screeching as the torque of the Jeep's 3.6-liter V6 and the frenetic clawing from its knobby BFGoodrich All-Terrains as it violently drags the steel of the Wrangler's floorpan along the rock's face. There's a groan from the front suspension as it reaches max articulation and the inevitable crunch when the solid mass mangles the thin gauge stainless steel of the JL's tailpipe. With the first obstacle cleared and 16 miles of America's most challenging off-road trail still ahead, I realize the Rubicon Trail Foundation has a lively sense of humor. Flip open the organization's printed map of the "world-famous Rubicon Trail" and the first thing you see is a quick list of tips to help you get from one trailhead to the other safely and responsibly. Right under where it advises you to pack out all trash and use the portable toilets, it states, "High clearance vehicles recommended." LOL. ROTF. LMAO. Bwaaaaahaaaaaaaa. That's a good one. But I guess it takes just one jerk in a Camry to ruin it for the rest of us. Jeep Jamboree USA, an organization famous for its off-road events on the trail, makes the point with a little less comicality, "A minimum of 33-inch tires, front & rear lockers, tow points, skid plates, rocker panel protection and CB Radios are mandatory requirements for the Rubicon Trail Jeep Jamboree," states its website in oversized bold letters. Our 2018 Jeep Wrangler Rubicon, the latest ultimate off-road factory Jeep on the new JL chassis, has all of it with the exception of the CB radio, which is unfortunate since black bears are easier to come by on the Rubicon than cell service. Our iPhones are as useless out here as mechanical sympathy for our steed. "Don't even try it," says one of our trail guides as he watches me fish my device from my luggage. "There's no service until we get back to Tahoe." That's a big 10-4. Lake Tahoe's crystal blue waters and charming downtown are about 30 miles from the Rubicon's eastern most trailhead. It's our finish line.
