2015 Jeep Cherokee finds a bit more fuel mileage thanks to stop/start and aero tweaks

Just a year after it burst onto the scene, Jeep has already made a pretty substantial addition to its V6-powered Cherokee, which has proven to be an extremely popular seller so far for the brand, adding a new stop-start system for the midsize, off-road-ready CUV.
The addition of stop-start included a few aerodynamic tweaks to the Cherokee's polarizing body, resulting in a wallet-pleasing increase in fuel economy. According to the EPA, the front-drive, V6-powered Jeep will now return 21 miles per gallon in the city and 29 mpg on the highway, up from 19 city and 28 highway. Four-wheel-drive, V6-powered Cherokees, meanwhile, will now return 20 mpg in the city and 28 mpg on the highway, up from 19 mpg in the city and 27 mpg.
With 271 horsepower, 239 pound-feet of torque and these newly enhanced figures, it's refreshing to see a larger, naturally aspirated engine that is still able to take the fight to today's crop of small-displacement, turbocharged four-cylinders.

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

Fires, deaths continue after Jeep fuel tank recall

As Kayla White slowed her SUV behind two other cars to exit a suburban Detroit freeway on Veterans Day, it was rammed from behind by a Cadillac STS. Her red 2003 Jeep Liberty bounced off a Nissan in front of it, rolled onto its side and exploded in flames. Other drivers ran to help but were forced back by the heat. Firefighters arrived in just three minutes but were too late. White, a 23-year-old restaurant hostess who was eight months pregnant, died of burns and smoke inhalation. White is one of more than 70 people killed in fires involving older Jeeps with plastic fuel tanks mounted behind the rear axle. Fiat Chrysler, which makes Jeeps, recalled 1.56 million of them in June 2013 under pressure from US safety regulators. But only 12 percent of the SUVs have been repaired in the 18 months since the recall, a much slower pace than usual. And White's Jeep was not among those fixed. Last week, prosecutors charged the Cadillac driver with committing a moving violation that caused a death. But safety advocates and the lawyer for White's family say the blame belongs as much, if not more, on Chrysler and an auto-industry safety system that moves too slowly to prevent tragedy. The rear-mounted tanks have little structure to protect them if struck from behind, making them susceptible to punctures and fires. Moving the gas tank in front of the axle would be expensive and difficult. So Chrysler's remedy involved installing trailer hitches on the rear of the Jeeps as an extra layer of protection. Government testing showed the hitches protected the tanks in crashes up to 40 mph when stationary Jeeps were hit from behind. But at higher speeds, they wouldn't help. White tried to get the repair done a few weeks before her death but was told by a Jeep dealer that parts weren't available, according to Gerald Thurswell, her family's lawyer. He wouldn't identify the dealership, and his contention could not be independently verified by The Associated Press. Thurswell contends the gas tank ruptured, spilling fuel that touched off the fire. A Chrysler spokesman expressed sympathy to White's family but said the company had no written proof that she asked a dealer about the recall. Two crash reconstruction experts interviewed by the AP say gas wouldn't have spilled from White's Jeep if the tank had been mounted in front of the rear axle. Both say a hitch might have prevented the tank from being damaged, but because both vehicles were in motion, neither expert could say for sure.
