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.

Jeep Grand Cherokee, BMW i8, Ford F-150 win 2015 Green Car Awards in DC [w/video]

There were three shiny trophies handed out at the Washington Auto Show last week by Green Car Journal, and they went to three different examples of what "green" means in the automotive industry today. The Jeep Grand Cherokee EcoDiesel won the award for the 2015 Green SUV of the Year, the BMW i8 was named the 2015 Luxury Green Car of the Year and the Ford F-150 took the 2015 Green Car Technology Award honor. There is a case to be made that the aluminum body of the new Ford truck will make a bigger impact in the overall fuel usage in the US than almost any other vehicle, given the numbers of F-150s that Ford sells each year. The B20 biodiesel-capable Jeep gets up to 30 miles per gallon on the highway. And the i8 puts all sorts of new, fuel-saving technologies into an attractive package. Looking over the winners, and the list of finalists you can see in our photo gallery, and you can see that the definition of green is expanding every year. You can watch Green Car Journal editor Ron Cogan hand out the 2015 awards in the video below and we'll for sure be paying attention to what wins next year. 2015 Luxury Green Car of the Year, Green SUV of the Year and Green Car Technology Winners Announced WASHINGTON, Jan. 22, 2015 /PRNewswire/ -- Green Car Journal has named the Jeep Grand Cherokee EcoDiesel its 2015 Green SUV of the Year™ and the BMW i8 its 2015 Luxury Green Car of the Year™, with the aluminum-bodied Ford F-150 earning the magazine's 2015 Green Car Technology Award™. Winners were determined by a jury of Green Car Journal editors and automotive experts. The prestigious awards were announced in Washington, D.C. today at a Green Car Awards™ press conference held during the Washington Auto Show's Public Policy Day at the Washington Convention Center. "These are truly commendable vehicles representing the 'best-of-the-best' in so many ways," said Ron Cogan, editor and publisher of the Green Car Journal and CarsOfChange.com. "The auto industry's very early focus on small cars and efficiency-for-environment tradeoffs has evolved to now include a more dynamic field of 'greener' models in all vehicle classes. Those wanting greater efficiency or better environmental performance are no longer constrained by limited choices or vehicle types that fall outside their top purchase preferences.

Chrysler axes old V6s, goes all-Pentastar

Old technology has a way of lingering on, particularly at Chrysler headquarters in Auburn Hills. So while the Pentastar V6 has replaced the older engine architecture in just about every application, it still soldiered on in some export markets. But the introduction of a new 3.0-liter Pentastar V6, produced in Michigan and meant only for the Chinese market, has put the final nail in the old engine's coffin.
Fitted into the 2014 Jeep Grand Cherokee and Jeep Wrangler just introduced to China at the Chengdu Motor Show, the downsized six uses the same architecture as the larger 3.6-liter Pentastar V6. But because of its 2,997cc capacity, it can be exported to China without the increased duty the 3.6-liter or even 3.2-liter Pentastar engines would incur. The 3.0-liter V6 develops 230 horsepower at 6,350 rpm and 210 pound-feet at 4,400 rpm.
Admittedly, it's unlikely, but even though the engine was said to be created solely to undercut tax thresholds in China and Europe, the 3.0-liter Pentastar has recently surfaced in rumors of an application here: as the boosted heart of a potential Cherokee SRT with anywhere from 375 to 410 hp.
