NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.

2018 Jeep Grand Cherokee Trackhawk Drivers' Notes | Haulin' the groceries

Powered by the same supercharged Hemi at the heart of Dodge's Hellcat cars, the 2018 Jeep Grand Cherokee Trackhawk is the sort of vehicle that comes from a " Why not?" attitude from the maniacs at SRT. It's not for the faint of heart, nor for the cash-strapped. With 707 horsepower and 645 pound-feet of torque, it's capable of a 0-60 sprint of just 3.5 seconds. Its base price, however, is $86,995, though our tester's sticker totaled just a few bucks shy of $100,000. Senior Editor, Green, John Beltz Snyder: "What business does a Jeep have going 0-60 in 3.5 seconds?" This was my thought as I merged into rainy rush-hour traffic on Woodward Avenue in the 2018 Jeep Grand Cherokee Trackhawk. "Why does an SUV need to have 'Track' in the name?" I thought as I unintentionally broke the tires loose pulling away from a stoplight. I hit the "Eco" button, but the Jeep still roared with every toe-tap, and still managed to gulp down nearly a quarter of a tank of gas on my ride home. That sound, though, is amazing, and surely more unsettling to other drivers coming from such a big beast of a ute. Anyway, this Jeep feels more grown-up than other Hemi-powered vehicles I've driven. The fit and finish in this $99,000 Jeep is far nicer than, say, the Dodge Durango SRT (though at a much higher cost). If another driver didn't pay close attention to the badging, they might see this and think it just another Jeep. The sound, though, will give it away every time. Associate Editor Joel Stocksdale: If Fiat-Chrysler knows how to do anything, it's making fast SUVs, and the Grand Cherokee Trackhawk is further proof of that. And by that I mean, they know how to make them fast, and they know how to make them pleasant to drive. The Trackhawk definitely handles the fast part better than its SRT Durango and SRT Grand Cherokee cousins, what with its extra 230-odd horsepower. This big beast seriously rockets when you punch the throttle. The nose rises up, the supercharger screams, the exhaust rumbles and the speedometer ticks up much faster than you'd ever think. And it feels strong at all revs. Also impressive is that you don't have to really think when flooring it. The all-wheel-drive and fat tires offer so much grip the Jeep simply goes. The pleasant to drive part comes in the fact that the Trackhawk is very comfortable. The suspension has plenty of give, providing a good ride over pockmarked Motown roads.

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.
