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.

Ram Long-Hauler prototype spotted testing, world about to get new largest pickup?

In the past few months, Chrysler's Ram brand has gone from also-ran status behind Ford and General Motors to a class leader in many truck categories including fuel economy (25 miles per gallon highway) and towing (30,000-pound maximum capacity). Now, based off these spy shots recently taken, it looks like Ram is preparing to introduce the be all and end all of pickup trucks, with a production version of its leviathan 2011 Long-Hauler Concept.
Our spy shooters recently caught the two-year-old concept truck running around Auburn Hills, MI covered in stickers that would indicate the truck could be testing for a production model, and last we heard back in September, Chrysler has been trying to build a business case for the massive hauler. On the other hand, seeing as how the only changes made to this truck since it was first unveiled are a full factory tailgate and various Mopar accessories (mud flaps, exhaust finisher and bed step), it doesn't appear that any changes have been made that fit in with the recently announced 2013 Ram HD models.
As a refresher, the Long-Hauler rides on the 197.4-inch wheelbase of the Ram 5500 chassis - usually reserved for stake or box trucks - allowing it to combine the luxury of the Mega Cab with the cargo capability of an eight-foot bed and enough room in between to fit a 60-gallon reserve fuel tank. This, along with the 50-gallon, in-bed fuel tank and the truck's factory fuel tank means that the Long-Hauler has the ability to carry 162 gallons of diesel fuel - enough for one incredibly long haul.
