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 Cherokee faces on-sale delay

A report in The Wall Street Journal looks at some of the obstacles to the 2014 Jeep Cherokee that go beyond its mootable yet "very contemporary" looks, almost all of them based on Fiat's financial position. Starting with that sheetmetal, in defense of it SRT president Ralph Gilles and Jeep design head Mark Allen said they wanted to "make sure the design still looks modern five years from now."
The WSJ piece doesn't cite longevity as a factor, instead saying that its features originated in a design for an Alfa Romeo, the transformation into a Jeep design meant allowing Chrysler get it to market more quickly and save "hundreds of millions of dollars" in engineering.
The need for Fiat to save money while it weathers the European situation has cut budgets for development, engineering and the pace of retooling the Toledo, Ohio plant to build the Cherokee. In a familiar case of snowballing at work, among the effects will be pushing back the Cherokee's volume sales date and delaying updates to some of Chrysler's other products.

Jeep Cherokee won't get diesel until sales of oil-burning Grand Cherokee improve

Okay Jeep fans, you want more diesel options? Time to step up and prove it. The only way Jeep will offer a diesel powerplant in the Cherokee, according to brand head Mike Manley, is if sales of the Grand Cherokee EcoDiesel nearly double.
Currently, about eight percent of the Grand Cherokees sold feature the 3.0-liter, EcoDiesel V6. That's simply not enough to warrant the bringing an oil-burning Cherokee to the US market, despite the vehicle's presence in Europe, where it's sold with a 2.8-liter diesel V6.
"Cherokee is slightly different because of its weight and size. When I think about bringing Cherokee diesel here, I would like to see Grand Cherokee diesel get much higher than eight percent," Manley told Automotive News. "It would have to be in mid-double digits."
