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.

Midsize Ram truck coming to U.S.

The midsize truck segment is officially back in full force. Today, at FCA's new five-year plan, company CEO Sergio Marchionne and Ram head Mike Manley announced that America will be getting Ram's new global midsize truck. The new model is designed for a global audience. It will not be based on the Mitsubishi Triton, we're told. FCA already sells that model in certain markets as the Ram 1200. Trucks for the North American market will likely be built in Mexico on the old Ram Heavy Duty production line. The upcoming Ram HD — set to debut at the 2019 Detroit Auto Show — will be built in the US. The timing of the new midsize Ram isn't pinpointed, but the above slide from FCA's presentation suggests we'll see it by 2022. A with all upcoming Ram models, look for some form of electrification, likely in the form of the 48-volt mild hybrid system that's set to debut later this year in the 2018 Ram 1500. Don't expect the truck to tailor too heavily to US tastes like the Toyota Tacoma or Chevy Colorado. Like the upcoming Ford Ranger, this is a global truck first and foremost. Marchionne said that Ram's focus in the US will remain mostly on full-size trucks. Still it will be sold in the U.S., just not in any expected large volumes. Related Video:

A beginner's guide to plowing snow with a heavy-duty truck

I live in a desert, so the only things getting plowed around here are mud flows and brewer neighbors. But I enjoy machinery and haven't plowed any snow since a "loaded" truck meant one with A/C and a CD player, so I jumped at the chance for a plow primer in a Ram HD on a Canadian airfield. Running a plow is like welding – the basics come quickly but experience pays dividends. The first thing to deal with is a frequently changing horizon because, stout as they are, even three-quarter-ton heavy-duty trucks will move up and down in front considerably with a 600-to-800-pound plow hanging off, and fast plow hydraulics rival some low-riders for bounce effect. Getting going is easy unless you forgot blocks and the plow froze to the ground, rookie. If you have to drive to your plowing assignment, blade height needs some experimentation to find the best cooling airflow; if you think sub-freezing temperatures negate that concern, remember you've installed what amounts to a 20-square-foot air brake up front that the truck has to overcome, and blowing snow could block some cooling air passages. Whether it's a "straight" blade or V design, always have it tilted to the right lest you catch a hidden post, solid mailbox, or edge of a snow bank. Most plow operators I spoke to rarely exceed 45 mph in transit because of cooling, front suspension travel, and common sense, and you should go even slower if you don't have some ballast like chains, extra fuel tanks, or a salt spreader to balance the load on the back. With trucks' relatively slow steering and all that weight up high, oversteer is best avoided. With a little clean space to get a run, stick it in Drive to gather momentum and lower the plow simultaneously to float, where the weight of the plow rests on and lets it run along the surface. Momentum is good until you hit something you didn't know about, at which point the plow's breakaway systems limit damage but your truck could still hit something big; caution never hurts. Start out at 10 to 15 mph, depending on consistency and depth, making a clean wave off one side. If you have to push it straight, as you slow coincidentally raise the blade at the bottom of the pile to shove it up higher. Carry too much speed here and you'll stop with an unceremonious thud. Common mistakes cited among a few experts were people pushing banks of snow rather than plowing it, and rushing the shift between Drive and Reverse, throttling up before the shift is completed.
