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.

Watch these Super Bowl car commercials [UPDATE]

On Sunday, February 3, the New England Patriots take on the Los Angeles Rams in Super Bowl 53 at Mercedes-Benz Stadium in Atlanta, Georgia. Some will watch because of the storyline of the old-school dynasty facing off against the new-school wunderkinds, but a large chunk of people will solely be watching for the commercials. Lucky for those who slot into the latter category, many of the manufacturers release their super bowl ads ahead of time, or have simply opted to release the commercials only online. Scroll down to see what car companies have already shown their cards. Audi Audi goes the comedic route in its clip for the Big Game. It starts with a grandpa showing his grandson a gorgeous Audi e-tron GT tucked away in a garage before he's shaken awake. Turns out he was just choking on a cashew in his cubicle at his boring job. Dodge Dodge does what it knows: create enough smoke to punch more holes in the ozone layer. Set to "The Devil Went Down to Georgia (the Super Bowl is in Atlanta, get it!?), a Challenger SRT Hellcat widebody, Charger SRT Hellcat, and Durango SRT are seen ripping through a city, leaving a trail of rubber crumbs in their wakes. Genesis Genesis has not yet released a commercial prior to the Super Bowl, but it is the official luxury vehicle of the NFL. Because of this, Genesis is hosting a fan experience for 10 days before the game. It will showcase the brand's cars, offer games, and have photos opportunities and autograph days. Hyundai Jason Bateman alert! Hyundai is one of the few companies to hook a major celebrity for its advertisement, and the casting is perfect. Bateman plays a doorman who takes people to various terrible events in life, including root canals, the middle seat, and shopping for a car. The ad centers around Hyundai's Shopper Assurance, which is Hyundai's new method for car shopping.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.
