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.

Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.

2014 Ram 1500 Diesel

Remember when Mahindra & Mahindra was close to offering a compact diesel pickup here? A million voices from the truck-and-bed-loving tribes of the Internet cried out at once in anticipation, only to be silenced in disappointment when it didn't happen. And this was for a jitney with a bed that didn't exactly look robust in its press photos. The message these fans had was clear: light-duty truck + a diesel engine = a prayer answered for a significant contingent of truck buyers.
Ram tells us a fullsize diesel half-ton has been the number-one demand from customers, and it will be the first manufacturer to grand the wish when the 2014 Ram 1500 goes on sale early next year - "late availability" in Q1 of 2014 is the official word - with a 3.0-liter, six-cylinder turbodiesel provided by VM Motori. If you're wondering about the engine source, VM Motori has been a Chrysler supplier since 1992. DaimlerChrysler bought VM Motori in 2000, and after a few ownership-stake changes since then, it is presently a 50-50 joint venture between General Motors and Fiat. That will change shortly, however, with Fiat recently announcing it will buy GM's share and take full control of the company.
