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 recalling nearly half a million Durangos and Grand Cherokees

Rule number one of public relations – save the bad news for Friday. Fiat Chrysler has adhered to that, announcing today that it'd be voluntarily recalling 467,480 SUVs. This latest recall could actually be thought of as a continuation of a September 2014 recall, relating to the fuel-cell relay. In that case, some 188,723 Dodge Durango and Jeep Grand Cherokee CUVs from model year 2011 were recalled. And this time, it's the Durango and GC in trouble again. FCA is adding crossovers from model years 2012 and 2013 to the fuel-pump recall, although only diesel-powered Jeeps with the 3.0-liter V6 that were sold outside of North America are affected this time around. As with the previous recall, deformities in the fuel-pump relay, which could affect its functioning. In most cases, FCA reports that the affected vehicles simply won't start, although they also could be prone to stalling. A new relay circuit will be installed that promises increase durability. Of the 467,480 vehicles being recalled, 338,216 were sold in the US market, 18,991 went to Canada and 10,829 were shipped south of the border, to Mexico. Outside of the NAFTA region, FCA is recalling 99,444 vehicles. No injuries or accidents have been associated with this recall. Statement: Fuel-Pump Relay February 27, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 467,480 SUVs worldwide to install new a relay circuit that improves fuel-pump relay durability. FCA US engineers have determined a condition identified in a previous investigation may extend to additional vehicles. The previous investigation, which led to a recall, traced a pattern of repairs to fuel-pump relays that are susceptible to deformation. This may affect fuel-pump function, preventing a vehicle from starting, or leading to engine stall. Of the two scenarios, the no-start condition is the more common. FCA US is unaware of any related injuries or accidents. The fuel-pump relay is located inside the Totally Integrated Power Module (TIPM), which also helps manage other vehicle functions. None of these other functions, including air-bag deployment, is affected by the fuel-pump relay. The new campaign affects an estimated 338,216 vehicles in the U.S.; 18,991 in Canada; 10,829 in Mexico and 99,444 outside the NAFTA region. Covered are model-year 2012 and 2013 Dodge Durango full-size SUVs and non-NAFTA 2011 Jeep Grand Cherokee mid-size SUVs equipped with 3.0-liter diesel engines.

Chrysler says its 8-speed transmissions will save 700 million gallons

Chrysler Group's TorqueFlite eight-speed transmission could be earning some serious green bragging rights if the company's projections are correct. The recently widely proliferated automatic gearbox, which is now in more than a million vehicles around the world, is poised to save drivers an estimated 700+ million gallons of fuel over the vehicles' lifetimes (an expected cost savings of $2.5 billion). In addition, Chrysler expects a reduction in CO2 emissions by more than six million metric tons. According to Chrysler, and depending on the vehicle, the TorqueFlite can improve fuel economy. The TorqueFlite autobox features particularly close ratios from fifth to eighth gear (see the press release below for the specific numbers), and uses low-viscosity fluid that doesn't need to be replaced. Transmission software adapts to the driving situation to optimize efficiency based on driver behavior, temperature, grade, stability control, and longitudinal and lateral acceleration. The TorqueFlite is capable of handling a variety of duties. As evidenced by the wide range of vehicles Chrysler Group has seen fit to equip with the eight-speed transmission, the TorqueFlite is capable of handling a variety of duties. Since its 2012 introduction, the TorqueFlite has gone from performing cog-swapping duties in Dodge Charger and Chrysler 300 models equipped with the 3.6-liter Pentastar V6 to changing gears in vehicles such as the Pentastar- and Hemi-powered Dodge Durango, Jeep Grand Cherokee and even the Ram 1500 EcoDiesel. For the 2015 model year, the eight-speed is finding its way into even more vehicles with the addition of a third version. In addition to the American-made TorqueFlite 845RE and 8HP70, the new 8HP90 will be manufactured in Saarbrucken, Germany. The 8HP90 is designed for higher torque loads, making it ideal for high-performance vehicles like the 2015 Dodge Challenger SRT Hellcat. The already-in-use 8HP70 will expand its duties to be used in 2015 Hemi models such as the Dodge Charger, Challenger, and Challenger SRT8. You can see the list of those benchmarks in Chrysler's press release below.
