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.

NHTSA closes book on Jeep 'trailer hitch' recall after all

After much debating and hand-wringing, the National Highway Traffic Safety Administration now says it has "no reservations" with Chrysler's plan to recall certain Jeep Liberty and Grand Cherokee models over concerns that their fuel tanks, which are located behind the rear axle, could rupture or leak in the event of a rear impact. The longstanding argument between the two entities saw Chrysler openly defy the Feds after a request to recall 2.7 million units back in June.
Chrysler's "voluntary campaign" will instead see it recall 1.56-million 1993-2004 model year Grand Cherokee SUVs, along with 2002-2007 Liberty models. Affected vehicles will get a trailer hitch installed free of charge, which Chrysler says will provide an additional degree of protection for the fuel tanks in the event of a crash. Jeeps with Mopar-branded hitches or hitches that were installed at the factory aren't affected by this recall.
Chrysler's argument throughout this battle has been that the Jeeps in question are no more susceptible to fires than comparable vehicles from the same time period, a position that NHTSA has seemingly arrived at as well. "Those vehicles performed at a rate similar to their peers. That is the keystone analysis as to whether something poses an unreasonable risk to safety," said outgoing NHTSA boss David Strickland during an interview with the The Associated Press.

Some Jeep Cherokees and Chrysler 200s to get standard stop-start in 2015

Automakers the world over are striving to find ways to make their models more efficient, and Chrysler has a solution for some versions of the 2015 Chrysler 200 and 2015 Jeep Cherokee (2014 model shown). The Tigershark 2.4-liter four-cylinder in the 200 and the 3.2-liter Pentastar V6 in the Cherokee are getting a slight boost later this year thanks to the addition of Chrysler's Engine Stop-Start system as standard equipment. The company predicts modest gains - a three-percent improvement in fuel economy and a three percent reduction in CO2 emissions with the new tech compared to without it. While it's not much, those who sit in traffic a lot may see a difference.
Chrysler's stop/start system uses a high-speed starter motor to restart the vehicle in a claimed a third of a second. It works by detecting when the vehicle comes to a stop and turning off the engine. A more powerful battery maintains all of the model's accessories while it sits. When the driver lets off the brake, the car starts up again to drive away. There is even a button in the cabin to turn the ESS off, if desired.
The Jeep will be the first to receive ESS in the third quarter of this year to coincide with the start of production of the 2015 model-year version. The 200 will follow in the fourth quarter as a rolling change in production.
