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.

100,000 Jeep Cherokee models subject to further 9-speed recalibration

It seems that the software problems with the nine-speed automatic gearbox in the Jeep Cherokee continue to mount. The programming already caused multiple development delays and even postponed the Cherokee's market launch by roughly two months. Now, Jeep has issued another recalibration to hopefully assuage unhappy drivers.
According to Automotive News, this reflash for the allegedly jerky transmission covers over 100,000 Cherokees built before May 5, but it's not technically a recall. If owners are having problems and complain to the dealer, they get the new software. Otherwise, they continue with the current version. New vehicles on dealer lots also receive the latest revision to the programming. It takes only around five minutes to install, but technicians need to take the Cherokee on a test drive to adapt the gearbox to the changes.
The Cherokee's transmission software has been problematic practically since the beginning. The Jeep plant in Toledo, OH, briefly idled its second-shift workers last year to take care of the issue. Since the launch issues for the crossover, demand has been strong. Jeep added another 1,000 temporary workers to the Toledo factory to keep up, and sales were on par with the Wrangler in just its first two months.

2015 Jeep Renegade

It's no secret that the midsize crossover segment is one of the most hotly contested battlegrounds in the automotive industry. Long have vehicles like the Ford Escape, Honda CR-V and Toyota RAV4 duked it out for those ever illusive consumer dollars. For many customers, though, even something like a Nissan Rogue is too big, whether in terms of price, fuel economy or just plain size.
For those customers, a growing market segment seems poised to fulfill their needs. Compact crossovers and tall wagons like the Nissan Juke and Kia Soul offer the high-riding driving experience with all the utility that comes from their two-box layout. It's an underrepresented segment among manufacturers, with big names like Toyota, Ford, General Motors and Honda lacking a true competitor.
To capitalize on this growing class, Chrysler's Jeep brand has readied this: the Renegade. That's right. Not Jeepster - Renegade. This diminutive off-roader, which rides on Fiat Chrysler's new small-wide 4x4 architecture, represents Jeep's first foray into the subcompact CUV segment as we know it, and it's making its official debut this week, on the floor of the 2014 Geneva Motor Show. Join us as we take a close look at one of Jeep's most important products in some time.
