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.

FCA's puzzling trademark spree includes Apache and Orange Peelz

Here's one for the Mystery Machine. As noted by the WagoneerFans forum and picked up by Motor1, Fiat Chrysler recently went on a one-day trademark application spree at the U.S. Patent and Trademark Office. On March 6, the automaker applied for the names Apache, Farout, Orange Peelz, Shocker, Tomahawk, and Top Dog. All have been requested for "Land vehicles, namely, passenger automobiles," and the best guess so far has them being applied to concepts during next month's Easter Jeep Safari, which, assuming it goes ahead, will happen April 4-20. As for historical ties, one name has a connection to Dodge, another was a codename for a Dodge engine, and one was used on a previous Easter Jeep Safari concept. Tomahawk rings the loudest bell, that name applied to the four-wheeled, Viper-engined concept motorcycle that Dodge rolled out at the 2003 Detroit Auto Show. The company supposedly sold nine examples of the "rolling sculpture" through Neiman Marcus over a four-year period. It doesn't appear FCA has used the name since, internally or otherwise. There is, however, a Cherokee tomahawk — not referring to a Jeep, but the light, short-handled ax used by the Native American Cherokee tribe. This one seems made for Safari use. Apache has a Dodge and a Jeep tie-in. At one time, Apache was the codename for the 6.4-liter Hemi V8 marketed as the 392 V8 on the Charger and Challenger R/T Scat Pack trims. That engine makes 485 horsepower and 475 pound-feet of torque. But Jeep showed a Wrangler Apache concept (pictured) at the 2012 Easter Jeep Safari, built with a Mopar conversion kit for a 6.4-liter Hemi making 470 hp and 470 lb-ft. Mopar sold the V8 swap kits at least through 2016, but they appear to have fallen off the Mopar menu. At one time there were rumors of a supercharged Apache with more than 600 horsepower, and wouldn't that be a welcome surprise in Moab. The Farout could be a more or less extreme overlanding take on last year's Easter Jeep Safari Wayout concept, depending on whether one considers "way" or "far" more radical. The Shocker, Jeep might be disappointed to discover, already has an outside link in the Jeep Shocker stickers made for Wichita State fans who love America's 4x4. As for Orange Peelz, it's pretty close to Pedro's bicycling degreaser called Oranj Peelz, but a Jeep conception could be anything. Except maybe a paint color.

2018 Jeep Wrangler owner’s manuals leaked, and they tell us much — but not all

If you're looking for some light reading to start your week, we have a suggestion for you. The " Owner's Manual" and the " User Guide" for the 2018 Jeep Wrangler have leaked, and have been posted on the JL Wrangler Forums. They appear to be the real deal. There's a ton of information, and many pages to pore over, but here's a little bit of what we've gleaned so far. The documents (assuming they're not just some very elaborate and convincing hoax) confirm the power sliding top, which is not removable, though the rear quarter windows are. We're not seeing any mention of a power soft top, though. There are instructions on door removal, as well as folding down the windshield. The manuals also confirm a 4WD Auto mode that shifts power between the front and rear axles as needed. What we don't appear to have yet are complete specifications. The manuals mention the 2.0-liter and 3.6-liter engines, but not their output figures. The 2.0-liter recommends premium fuel, while the 3.6-liter only needs 87 octane. Towing capacity for the two-door models is 2,000 pounds, while the four-door versions are capable of 3,500 pounds. The manuals also provide a lot of images, if you're interested in seeing the nitty gritty details of the Wrangler's various functions. Take a look, and make sure to post any interesting findings in the comments section, below. Related Video:
