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.

Dodge Challenger spied exercising supercharged Hellcat Hemi V8

One of the prime complaints against the Dodge Challenger is that, even in SRT8 guise, its 470 horsepower is responsible for hauling over 4,200 pounds of vehicle. For comparison, the 420 hp in the Ford Mustang GT only has to deal with 3,618 lbs. Things only get worse from there, as the higher-performance variants of both the Mustang and the Chevrolet Camaro are far more powerful than an SRT8 without adding on much heft.
So what is Chrysler to do? The correct answer is add a whole lot more grunt to its hefty two-door and even the odds. That's where the all-new Hellcat engine comes into play. We reported on this engine in May, and suggested that the Hellcat, a supercharged powerplant based on a 6.4-liter V8, would easily generate 500 to 570 hp and could likely arrive boasting more than 600 ponies.
Chrysler's ace in its sleeve has now been spied testing, with a number of Hellcat-equipped Challengers running the potent new engine both in more urbanized areas and under the sun of Death Valley. The hoods on these testers have been raised to accommodate the engine, and that camouflage over the fascias of these prototypes is there to hide a larger air intake. We also note what appears to be a new split grille under wraps. As for power output, our spies are now suggesting a Viper-equalling 640 hp from the Hellcat-equipped cars.

Almost 70 percent of FCA-PSA Groupe models to ride on two PSA platforms

With the merger between PSA Groupe and Fiat Chrysler having been officially announced this week, we still don't know where everything will settle once the process concludes. We covered the catalog of models herded by the combined company's 12 brands, all of which will remain for now. Profound changes must be afoot somewhere, though, else there'd be no reason for the tie-up. Automotive News has a report on one of the big moves, writing that "more than two-thirds of [PSA-FCA] production would be concentrated on just two platforms." Around 2.6 million cars built by the combined company would sit on PSA's Common Modular Platform, also known as the EMP1, for B-segment city cars, entry-level and mid-range C-segment sedans, and compact crossovers. Three million vehicles would ride on the EMP2 architecture intended for C- and D-segment cars and higher-end crossovers. Those figures account for around 5.6 of the 8.7 million vehicles the combined company expects to sell annually. AN didn't mention the Giorgio platform that's already spread throughout the FCA kingdom to support numerous current and future offerings like the next-gen Jeep Grand Cherokee, but did write that "larger Jeep models will continue to use FCA underpinnings." The body-on-frame chassis' under Ram trucks and the Jeep Wrangler and Gladiator should hold pat. We'll wait for word on the fate of the Compact U.S. Wide platform carrying the Chrysler Voyager and Pacifica and Jeep Cherokee. Dodge products with questionable futures are anyone's guess; we've heard the Dodge Durango, still built on a Mercedes-derived platform it shares with the current Grand Cherokee, could go body-on-frame for the next generation, or die and have the Giorgio-based, three-row Jeep Grand Cherokee take its place. More mystery comes with the long-lived LA and LD platforms in the big sedan and coupe trio Chrysler and Dodge still milk quite successfully. And if there were ever a time for the Dodge Journey – last reported as a Giorgio recipient – to modernize or die, we don't know when that time is. Although FCA platforms have been designed with alternative powertrains in mind, AN says the PSA Groupe architectures "are more modern than FCA's equivalent platforms." After PSA acquired GM's Opel/Vauxhall division, the French company didn't waste time moving the Anglo-German products to in-house platforms, helping to put the formerly money-losing operations into the black in just 18 months.
