NHTSA investigates FCA for SUVs that roll out of Park

The National Highway Traffic Safety Administration is opening a preliminary evaluation into the 2014 Dodge Durango and 2014-205 Jeep Grand Cherokee after 14 complaints of the SUVs rolling out of Park. An estimated 408,000 of them could be affected, if a recall is necessary. All of the current complaints submitted to NHTSA about the issue concern the Grand Cherokee, and the claims allege that the SUV can roll out of Park whether or not the engine is running. Some folks report that they check the indicator each time because the gear sometimes fails to engage. Among the 14 cases, there are five accounts of crashes and three injuries, including a situation with someone allegedly being rolled over. NHTSA's preliminary evaluations are meant to investigate "the scope, frequency, and safety-related consequence" of a reported problem. They don't necessarily lead to a recall.

The unintended motion has occurred with both the engine off and the engine running. ODI has also identified EWR field report data related to the alleged defect. The model year 2014 and 2015 Jeep Grand Cherokee vehicles are equipped with an electronic gear selector (shift-by-wire system). The gear selection is made by pressing the shifter-paddle forward or backwards; the shifter does not move along a gate path as with conventional gear selectors. A Preliminary Evaluation has been opened to asses the scope, frequency, and safety-related consequence of the alleged defect. The VOQs associated with the opening of this investigation are: 10733158, 10730952, 10683556, 10679497, 10583366, 10725429, 10715401, 10711893, 10676998, 10668651, 10662619, 10662308, 10605865, and 10567538.

Build a Jeep Gladiator 392 next? The Hummer H3T Alpha blazed the trail

The 2021 Wrangler Rubicon 392 will combine the go-anywhere capability of a Jeep's iconic off-roader with the grunt of a V8 for the first time in decades. As cool as that is, we can't help but think Jeep is missing out on a huge opportunity to pair that 470-horsepower, 6.4-liter Hemi V8 with the Wrangler's pickup cousin, the Jeep Gladiator, in the form of a Mojave 392.  Autoblog took part in a media Q&A session with Jeep ahead of the Rubicon 392's announcement in which the company's product higher-ups said that there are currently no official plans to build a 392 variant of the Gladiator pickup. But whether or not Jeep has plans, it certainly has precedent, and from our perspective, a market.  Rewind to 2008, better known as one of the worst possible years to introduce a gas-guzzling, V8-powered pickup truck. Enter the 2009 Hummer H3T Alpha, the first variant of Hummer's midsize truck/SUV hybrid to be offered with a 5.3-liter V8. The 300-horsepower small-block was an upgrade to the sturdy but relatively uninspiring 3.7-liter inline-5 that the H3 lineup had inherited from its midsize pickup platform mates.  As our Jeremy Korzeniewski noted in the Rubicon 392's introductory piece, an open-top Jeep has not been offered with an optional V8 for as long as the "Wrangler" nameplate has existed. The last Jeep 4x4 to do so was still a CJ, or civilian Jeep, and the 304 cubic-inch engine came from American Motors Corporation. Incidentally, this generation of the Wrangler is also the first to be offered in a pickup variant. Cue the beard-stroking.  Now, frankly, it's not even remotely fair to compare the H3T's powertrain offerings to the decade-newer Gladiator's, but the Hummer actually boasts a few advantages over Jeep's modern pickup. While most of the Jeep's off-road specs give it an edge, the Gladiator doesn't come close to the H3T's 30.1-degree departure angle, for instance. And in more practical terms, the stubbier H3T has other maneuverability advantages. The Gladiator has 3" of wheelbase and 5" of overall length on the H3T, and a 22.4-foot turning radius to show for it. The Hummer's? Just 18.5'.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.
