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.

2014 Jeep Cherokee musters 22 MPG city, 31 highway

Production and media drive delays included, there has been no lack of press surrounding the 2014 Jeep Cherokee. With the most recent delay reportedly due to powertrain calibrations, we've been waiting to see how the Cherokee's fuel economy looks against the highly competitive compact CUV segment. Thanks to the EPA, we now know the fuel economy figures for the newest member of the Jeep family.
Arguably, the Cherokee has the most modern powertrain in its class with an updated base engine, all-new V6 and all-new nine-speed automatic transmission, but its fuel economy figures are simply on par for the segment. Still nothing to scoff at, though. According to fueleconomy.gov, front-wheel-drive Cherokee models with the base four-cylinder mill will top out the lineup with 22 miles per gallon in the city and 31 mpg on the highway; opting for four-wheel drive with this engine drops the figures to 21 city and 28 highway. Get even crazier with the option list, and the new 3.2-liter Pentastar V6 will get you 19 mpg city and 28 mpg highway in two-wheel-drive form or 19 city and 27 highway for 4WD.
If you're wondering how that stacks up among compact CUVs, head on over to Automobile Magazine for a full fuel economy breakdown for the segment. The controversially styled crossover hits dealers this month, and we'll be driving it in just a couple of weeks.

Hellcat motor 'fits like a glove' in the Wrangler and Gladiator, says Jeep

Just like "technically correct" is the best kind of correct, "technically possible" is the best kind of possible. Specifically, it's technically possible to slot a Hellcat crate motor into the Jeep Wrangler and Gladiator, as confirmed by Jeep brand chief Tim Kuniskis. Speaking to Australian media last week, Kuniskis went on to say that "everybody" keeps asking him if the supercharged, 6.2-liter Hellcat V8 fits in the Wrangler and Gladiator, and that the answer is yes. "It fits like a glove," said Kuniskis. But — there is a but — the fitment is so close for comfort, it makes the combination one that Jeep can never produce. "There's no air space around the engine [...] so you have no crush space, you have nothing that can be used to absorb energy in a crash. It's not a problem to put it in — other than emissions and fuel economy — except it would never pass any crash tests, and that's a problem," as Kuniskis told Drive. However, since the Hellcat is now out of the bag, it's probably only a matter of time until hobbyists with access to these engines will start putting them into Wranglers and Gladiators. And with the time-honored piece of advice — just don't crash into anything — it'd be a combination worth seeing and hearing. Just to throw it out there, a "Hellcrate" engine costs less than $20,000 new. Kuniskis also said that Jeep is "gauging interest" for the J6 concept, one of the Easter Jeep Safari concepts that were just revealed. "[The J6] is just a concept at this stage. But that doesn't mean we're not going to gauge interest for it." However, he said justifying its production is apparently "tough."
