164K Jeep Cherokees recalled to protect liftgate from moisture

FCA is recalling 164,003 examples of the 2014 and 2015 Jeep Cherokee because moisture can damage the power liftgate controls on models that are equipped with that feature. Regionally, this includes 99,436 of them in the US, 13,195 in Canada, 2,406 in Mexico, and 48,966 outside of NAFTA. The problem came to light after the automaker started investigating a fire in one of the SUVs. There were no injuries, though. According to FCA US' research, the power hatch's control module potentially can be exposed to water. This can cause a short circuit and possibly a fire, as in this case. Until the issue is repaired, the company is advising owners to keep the cargo area dry on Cherokees equipped with this feature. To fix things, dealers will install a shield around the controls to protect them from moisture and will replace any modules showing exposure to water. Statement: Water-Shield Installation June 24, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 99,436 SUVs in the U.S. to install shields that protect their power liftgate control modules, and related components, from moisture. FCA US LLC began an investigation after learning of a reported vehicle fire. The probe revealed power liftgate control modules in certain SUVs may be inadvertently exposed to water. This may cause a short-circuit, creating a fire hazard. However, the Company is unaware of any related injuries or accidents. The campaign affects model year 2014 and 2015 Jeep Cherokee SUVs, but is limited to vehicles equipped with power liftgates. An estimated 13,195 customers are affected in Canada, along with an estimated 2,406 customers in Mexico and 48,966 outside the NAFTA region. The estimated total recall population is 164,003. All affected customers will be advised when they may schedule service. If the modules show signs of water exposure, they will be replaced. All recall-related work will be performed free of charge. In the interim, the cargo areas of 2014-15 Cherokees equipped with power liftgates should be monitored and kept dry. Customers with questions may call the FCA US Customer Information Center at 1-800-853-1403.

Vile Gossip | Adventures in tire testing

Jean Jennings has been writing about cars for more than 30 years, after stints as a taxicab driver and as a mechanic in the Chrysler Proving Grounds Impact Lab. She was a staff writer at Car and Driver magazine, the first executive editor and former president and editor-in-chief of Automobile Magazine , the founder of the blog Jean Knows Cars and former automotive correspondent for Good Morning America . She has lifetime awards from both the Motor Press Guild and the New England Motor Press Association. This is her first column for Autoblog — look for more Vile Gossip in the future. I began writing at Car and Driver magazine back in its golden age in the 1970s, before I'd actually read it. I knew very little about cars. The only magazine I read religiously was Four Wheeler because I owned big trucks and liked to go off-roading with my Chrysler Proving Grounds friends. My vast 10 years of driving experience up to that point (high-speed dirt-road idiot, taxicab driver, Chrysler Proving Grounds test driver) had less bearing on my being hired at Car and Driver than the fact that the editor just wanted to rile up the all-male staff. He didn't need me for that. They were already in full dudgeon when I arrived. They'd just spent a chunk of time testing a stack of tires for their big tire-test issue, and the editor-in-chief was toe-to-toe with the technical editor over the rankings of the top 10 tires. It was loud, and it was angry. I had no idea that car magazines tested tires. Cab driving had led me to believe that airing up a tire and changing a flat was all you needed to know. I changed so many flats on that cab, I eventually wound up in front of a live audience on the " Oprah Winfrey Show" demonstrating my brilliance with a jack and a tire iron. My point, of course, is that tires are more controversial, and also more essential, than you'd think. My other point is that it's good to get worked up about the subject, but not quite so good to let yourself be seen, as I did, on my hands and knees with my ass up in the air on national TV. This is how I prefer to test a tire: First, pick a top brand. Then accept their invitation to try and beat the crap out of their tire. I chose Yokohama, celebrating its 100th anniversary this year. The big news for them was the GEOLANDER M/T G003!

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.
