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.

2014 Jeep Cherokee: Long-term wrap-up [w/video]

Sorry, Sweet Brown. Your place in Autoblog history as the most highly demanded long-term car has come to an end. We just finished a one-year test of a 2014 Jeep Cherokee Trailhawk, and after 27,000 miles of hard use, one thing is very clear: this is one of the best all-rounders we've ever tested. The Jeep Cherokee isn't perfect, and our long-term tester proved that. But no compact crossover is. Still, the Trailhawk oozed personality where other small CUVs seem bland, and the Jeep felt more like a trusty companion than just another test car. For road trips, the requests weren't, "Can I have a long-term car this weekend?" They were specific: "I'd like the Cherokee, please." No matter the season, the driver, or the situation, the Jeep was always a sure fit. Fiat Chrysler bet big with this one. It had a global platform, a new engine, and one heck of a funny face. The end result was a CUV that we'd gladly welcome back into our fleet any day. View 51 Photos Our car carried a sticker price of $38,059, but that's without goodies like HID headlamps, a sunroof, or even full leather seats. Lots To Like Admittedly, we picked the Trailhawk trim for cosmetic reasons (more on it's off-road capability in a second). To this day, many of us still think the Cherokee is a homely little thing, but its inherent weirdness doesn't stand out as much when you add the black accents and big, knobby tires of the Trailhawk model. The butched-up look really works here, and we wouldn't have wanted the Jeep any other way. Of course, opting for Trailhawk package meant getting one of Jeep's more expensive Cherokees. Our car carried a sticker price of $38,059, but that's without goodies like HID headlamps (which we could have used – the halogens were pretty weak), a sunroof, or even full leather seats. This car genuinely felt premium, though. Right off the bat, the Cherokee received compliments for its comfortable, supportive seats, not to mention the high quality of interior materials and the general fit and finish. Specifically, the interior packaging won us over early on. We appreciated things like the higher-end stereo, smart layout of the center console, and ample storage, including a bin under the front passenger seat cushion. (That said, we also found that this bin becomes a catch-all for wrappers, french fries, and anything else that might get dropped on the seat.) The Uconnect infotainment system was a joy to use, never giving us any finicky problems or usability issues.

Watch this 840-hp Jeep Grand Cherokee SRT8 walk away from GT-Rs and M3s

This last-generation Jeep Grand Cherokee SRT8 does things that SUVs just shouldn't be able to do, like win drag races against tuned Nissan GT-R and BMW M3 coupes. Granted, the owner isn't coming into this fight with a stock Jeep – far from it. In addition to twin turbos whistling away, he says the engine is a 449-cubic-inch V8, which is nearly 7.4 liters of displacement. As it runs here, the driver claims that the turbos are pumping out around 14 psi of boost to give an estimated 840 horsepower. What's more, he further maintains the powertrain could reach around 1,200 hp with things fully cranked up. Even somewhat dialed back, this Jeep is ready to take on a breadth of formidable challengers, including a couple of Chevrolet Corvette models and a Lamborghini Aventador. Check out the video to see how this menacing Grand Cherokee fares in a day at the races.
