NHTSA investigating power modules on Chrysler Group SUVs and minivans

The Center for Auto Safety is officially petitioning the National Highway Traffic Safety Administration to begin scrutinizing alleged problems with the totally integrated power module (TIPM) on about 24 Chrysler Group SUVs and minivans. The advocacy group claims that the part's failure can cause affected vehicles to stall or not start at all. NHTSA is still looking into the accusations and deciding whether a full investigation is actually warranted.
The CAS petition claims at least 70 TIPM failures, but according to NHTSA, six of the complaints are for models that don't have the modules. In 34 of the reported cases, the vehicles refused to start, and in 17 of them the engine stalled. There were also two allegations of smoke and one of a fire. However, none of these affected airbag deployment or resulted in a crash.
This petition isn't the first TIPM-related problem for Chrysler Group. A recent report in the New York Times alleged that it found 240 complaints potentially related to the issue on NHTSA's website alone. In September, the automaker also recalled 230,760 examples worldwide (188,723 in the US) of the 2011 Jeep Grand Cherokee and Dodge Durango replace the fuel pump relay circuit inside of the TIPM-7 with one external to the unit. The original part could allegedly cause the models to stall without warning. Even earlier, the company also recalled about 80,000 examples of the Jeep Wrangler and Dodge Nitro in 2007 to have the module reprogrammed.

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.
