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.

Ford Police Interceptors dominate Michigan State Police testing

Once again, Ford Motor Company builds the fastest police vehicles. The Blue Oval touted the news in an official release following Michigan State Police and Los Angeles County Sheriff's Department testing. Ford did very well. Except for one acceleration metric – zero to 10 miles per hour – the Blue Oval's Taurus and Explorer-based cop cars were the quickest, with particular praise coming for the EcoBoost-powered models, which bested Chevrolet and Dodge's V8-powered variants. Dearborn's products also posted the fastest average times around MSP's vehicle dynamics course. But it wasn't all positive for Ford. The only four-cylinder in the contest, the 2.0-liter, EcoBoost Ford SSP Sedan, had both the lowest top speed, 120 mph, and the slowest acceleration figures. It was also the slowest in track testing. Ford's products also failed to match the braking and top speeds of its rivals from Detroit and Auburn Hills – the rear-drive Charger Pursuit posted the best braking stats of the entire test, while the V8-powered Chevrolet Caprice hit the highest top speed, at 155 mph. Ford did score a top speed award, among SUVs, but at 132 mph, the naturally aspirated Police Interceptor Utility had to share its award with the equally fast, rear-drive Chevrolet Tahoe. The LA County Sheriff's timing isn't publicly available, but according to Ford, the EcoBoost-powered police cars put on a similarly impressive show for cops on the West Coast. We've assembled a spreadsheet on Google Docs that offers an easy to browse comparison of the different stats assembled by the Michigan State Police, and divided the vehicles between standard V6-powered sedans, high-performance sedans (EcoBoost and V8 models), and SUVs.

Playing in the snow | 2017 Dodge Challenger GT First Drive

The previous day was miserable. An icy rain fell over Portland, Maine, coating the pavement and making even walking a chore. Driving a muscle car like the Dodge Challenger seems ill-advised. But this is exactly the weather Dodge hoped for, because we're here to test the new all-wheel-drive 2017 Challenger GT. The morning of our test drive dawns sunny and cold. The remnants of a late January nor'easter now past, we nonetheless steel ourselves for a day of unruly roads. Stepping into an inch of slush, we open the huge door, climb inside, and nestle into the heavily bolstered driver's seat. Immediately comfortable, we know the Challenger well. It's an old friend. Late in life, it's finally finding stability. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Heading onto the Maine turnpike, we're struck by the Challenger's poise. All-wheel drive civilizes the coupe's brutish nature. We confidently navigate the first on-ramp – still wet from the storm – and merge onto the highway. A rear-wheel-drive car would come unsettled here, yet this Challenger's 19-inch wheels wrapped in all-season Michelin rubber are not disturbed. At the very least, the specter of tire spin would have made us overcautious. All-wheel drive doesn't morph the Challenger into a Subaru Outback, but it does make the Mopar a realistic year-round option for buyers north of the Mason-Dixon line. Dodge arrived at this conclusion after some introspection. The Challenger and its sibling the Charger sedan are usually cross-shopped with each other, and design is often the deciding factor. With Charger AWD sales remaining strong (in 17 Northern states at least 50 percent of Chargers are sold with the system), not offering an all-wheel Challenger leaves money on the table. Ben Lyon, Challenger brand manager, says the common refrain was, "I would have bought a Challenger, or I would have bought a two-door muscle coupe, if it was available with all-wheel drive." View 50 Photos Naturally, the Dodges share an AWD system, which has an active transfer case and the ability to disengage the front axle, making the Challenger a rear-wheel-drive car in certain conditions to help save fuel. Ambient temperature, wheel slip, Sport mode, passing situations, and the driver's behavior can trigger the all-wheel capability.
