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.

Chrysler investigating complaints of vehicles with faulty power modules

Chrysler owners are hopping mad after experiencing a series of electrical gremlins in some of the company's vehicles. Issues range from mere annoyances - windows rolling down and radios turning off of their own accord - to serious safety issues, with headlights that randomly shut off at night and cars that stall and refuse to start.
The issues are being blamed on the total integrated power module, which can cost up to $1,000 for customers to replace. This, of course, has led to a hefty batch of complaints to the National Highway Traffic Safety Administration, with 240 owners expressing their displeasure so far. Another site, CarComplaints.com, has registered over 300 complaints relating to the 2010 to 2011 Jeep Grand Cherokee and Dodge Durango, alone, according to The New York Times.
Chrysler has acknowledged that it's investigating the complaints and is analyzing the faulty TIPMs, but that isn't quite enough for customers of the affected vehicles. The newspaper has snagged a few of the more harrowing tales with the electrically challenged Chrysler products, culled from the NHTSA complaints.
