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.

2013 Ram Heavy Duty seeks to obliterate rivals with claimed 30,000-pound max tow rating

No one can accuse Ram of backing away from the full-size truck arms race. Chrysler has officially dropped the payload details on its 2013 Ram Heavy Duty, and the 3500 now packs a maximum trailer weight of 30,000 pounds. Chew on that number for a moment. That's 15 tons, or the equivalent of a dozen Mazda MX-5 Miata convertibles stacked on a trailer, and it's also a whopping 6,900 pounds more than the closest competitor to the Ram 3500, the Chevrolet Silverado 3500 HD. Ram engineers have cranked the truck's 6.7-liter Cummins turbo-diesel engine to a ludicrous 850 pound-feet of torque, up 50 lb-ft over the 2012 model. "Shock the world" figures, all.
Throw in a stiffer frame, stouter transfer case, beefed-up transmission and brawnier U-joints in the driveline, and you have what Ram is calling "the most capable trucks we've ever built." That includes the Ram 2500, which has seen its towing capacity swell to 18,350 lbs and its Gross Combined Weight Rating jump to 25,000 lbs. Look for the 2013 Ram 3500 HD to bow at the 2013 Detroit Auto Show, and be sure to check out the full press release below for more information.

Chrysler recalling 2009-2010 Ram 1500, Dodge Dakota pickups over axle pinion nut

Chrysler is issuing a recall for the 2009 and 2010 Ram 1500 and Dodge Dakota pickup trucks due to improper installation of the rear axle pinion nut. According to the National Highway Traffic Safety Administration, a total of 44,300 trucks are affected by the recall, and there have been 12 confirmed incidents including one crash.
The issue on both trucks is that the pinion nut is loosening on some trucks due to a lack of thread adhesive, and it is causing the rear axle to lock up resulting in loss of vehicle control. NHTSA's recall notice says that eight incidents occurred at speeds over 35 miles per hour and most also exhibited driveshaft failures as well since the loss of the pinion nut would cause the gear to separate from the driveshaft. In one complaint, the driveshaft separated from the rear axle and punctured the gas tank.
Chrysler will begin sending out recall notices to affected owners in November, but scroll down to see the official NHTSA notice.
