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.

Chrysler resolves recall issue with NHTSA, will inspect, upgrade affected Jeeps

Chrysler made big news earlier in the month by refusing a recall request from the National Highway Traffic Safety Administration for the 1993-2004 Jeep Grand Cherokee and 2002-2007 Jeep Liberty. Last week, NHTSA boss David Strickland countered by defending his agency's request for the recall of 2.7 million Jeep SUVs. Today marked the deadline for Chrysler to formally respond to NHTSA, and it seems that both parties have met in the middle with Chrysler inspecting and upgrading some of the affected vehicles without using the word "recall," which would constitute the admission of a defect; instead, Chrysler said that it is conducting a "voluntary campaign."
At issue on these vehicles is the positioning of the fuel tank behind the rear axle that could get damaged during a rear-end collision. NHTSA has stated that at least 51 people have been killed in rear-end collisions involving these Jeeps after the vehicles caught fire, to which Chrysler countered by pointing out that both models "met and exceeded" the requirements for fuel-system integrity.
As a compromise on the situation, Chrysler says that it will inspect all pre-2004 Grand Cherokees and pre-2007 Liberty models and, "if necessary, provide an upgrade to the rear structure of the vehicle." According to Automotive News, this upgrade will consist of adding a trailer hitch that will presumably better protect the rear-mounted gas tank. Vehicles already equipped with a factory or Mopar hitch will not be modified. Chrysler's official statement on the matter is posted below, but no additional information has been released, such as when the campaign will begin and how many vehicles could be affected.

Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.
