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.

FCA and ZF issue recall on nine-speed automatic transmission

After years of complaints, German transmission manufacturer ZF is finally issuing a recall of its much maligned 9HP nine-speed automatic transmission. Although it has been criticized for a number of issues, ZF is issuing the recall to address the possibility of the transmission unexpectedly shifting into neutral. The issue covers 505,000 vehicles in the United States alone. This issue is related to an improper crimp on the transmission wiring harness. Rather than a physical fix, ZF is issuing a software update to remedy the problem. The company doesn't recommend dealers attempt to fix the crimp. Although the transmission can be found in a number of models by various manufacturers, currently only those from FCA are being recalled. This is the second recall in less than a year related to a ZF transmission shifting into neutral. FCA recently recalled more than a million vehicles worldwide because of a poorly designed shifter for ZF's 8HP eight-speed automatic. That issue may have resulted in the death of actor Anton Yelchin in June. Although there are no deaths related to this new recall, NHTSA reports that the issue has resulted in at least 10 injuries. Issues with the transmission have been known for years. A number of software updates have attempted to address various problems, making us wonder if there could be a fundamental hardware issue as the complaints span across a number of automakers. Vehicles equipped with the 9HP include 2014 and newer versions of the V6 Acura TLX, Chrysler 200, Fiat 500X, upper-level Honda Pilots, Jeep Cherokee and Renegade, Land Rover Discovery Sport and Range Rover Evoque, and Ram ProMaster City. Only FCA is issuing a recall and only on 2014 and 2015 models. Related Video: News Source: NHTSA Recalls Chrysler Fiat Jeep Safety FCA nine-speed transmission

Jeep to stop using bad Takata airbag inflators next week

FCA is gradually ceasing to produce vehicles equipped with Takata airbag inflaters found to be inherently faulty. These airbags, which lack a certain drying agent, have been linked with dangerous premature ruptures. According to FCA, the only vehicle still in production with the named airbag is the 2016 Jeep Wrangler, and in this case they are passenger-side airbags. Fiat Chrysler says it isn't aware of any incidents involving these air bag inflaters in Jeeps, but amidst concerns that vehicles with failure-prone airbags are still being marketed to customers, North American-market 2016 Wranglers will cease to be equipped with them starting next week. As per FCA's statement, global production is expected to end by mid-September. In addition to Toledo, Ohio, the Wrangler is produced in Egypt. FCA isn't going to sell the cars with the deemed-faulty airbags without disclosing the fact to the customers: anyone buying a 2016 Wrangler will be notified that the vehicle will most likely be subject to a recall in the future, even if there is not currently a recall announced for them. NHTSA has specified a "Coordinated Remedy Program" recall schedule for the coming years, and the airbag inflaters will degrade over a time frame of several years, when subjected to a humid environment.
