Jeep recalls 228k Cherokees over airbag deployment fears

Jeep is recalling an estimated 228,181 examples of the 2014 and 2015 Jeep Cherokee worldwide because the airbags can inadvertently deploy in some situations. Specifically, the campaign covers 168,092 vehicles in the US, 19,557 in Canada, 4,133 in Mexico and 36,399 outside of North America. According to Jeep, the problem occurs when drivers execute extremely hard handling maneuvers and upset the vehicle's balance, which causes the side-curtain and seat-mounted side airbags to deploy. "The air-bag systems, sensing potential rollovers, automatically activated," according to the automaker's announcement. While this occurred in "a small number" of cases, according to Jeep, the problem caused no reported injuries or accidents. To fix the fault, the company will issue a software update to recalibrate the bags' deployment. Statement: Restraint-System Software Upgrade February 2, 2015 , Auburn Hills, Mich. - FCA US LLC is launching a global recall of an estimated 228,181 SUVs to upgrade software governing side-curtain and seat-mounted side air bags. The action follows an investigation by FCA US engineers after a small number of inadvertent deployments involving drivers who executed extreme maneuvers. These maneuvers dramatically changed the vehicles' angle of operation, relative to the ground. The air-bag systems, sensing potential rollovers, automatically activated. FCA US is unaware of any related injuries or accidents. The software upgrade will recalibrate the threshold for deployment and the vehicles will remain compliant with all applicable safety regulations. Affected are certain 2014 and 2015 Jeep Cherokees. Estimated volumes by market are as follows: 168,092 in the U.S.; 19,557 in Canada; 4,133 in Mexico and 36,399 outside the NAFTA region. The Company will notify affected customers. Software will be available at that time. Customers with additional concerns or questions may call 1-800-853-1403.

Here's what it'll take to build a Jeep Grand Cherokee Hellcat

Let's get one thing straight: We want a 707-horsepower Grand Cherokee Hellcat to happen. Badly. The latest report from Motor Authority is encouraging; the bonkers SUV supposedly has a codename, Project K, and has been given the green light for production. Fingers crossed. You might be wondering why the Trackhawk isn't already a thing. Hellcat engines exist, SRT Grand Cherokees exist, so just combine the two, right? It's not quite that easy. Here, we outline what needs to happen, why it should be the quickest Hellcat vehicle out there, and why it won't come anywhere near 200 miles per hour. How To Build A Hellcat Jeep The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged V8. The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged Hellcat V8. Breathing is important on two counts: pulling in enough air for the combustion to put out 707 hp, and then cooling the various heat exchangers once the engine is up to temperature. Dodge did it with the Charger and Challenger, it can do it with the Jeep. This is one place where the Grand Cherokee's larger frontal area might be a boon, as it gives the engineers more surfaces through which to suck air. Once you generate the 707 horsepower and 650 pound-feet of torque, it has to get to the wheels somehow. Jeep's current SRT all-wheel-drive system will at least need some beefing up to handle the torque. It could require a more complete re-engineering. We at least know the ZF-supplied eight-speed auto, used in the Dodge Hellcat models, is up to the task. The Hellcat engine should fit in the Grand Cherokee, as it's about the same size as the 6.4-liter currently in SRT Jeeps, but the Hellcat is taller because of its supercharger. The hood may need to be raised or at least resculpted for clearance, as well as to address those cooling needs. Quicker Than Everything, But Not Faster 200 mph? We're skeptical, from both a physics standpoint and a legal one. A reminder of the quick/fast distinction: quick is acceleration, fast is road speed. The Jeep's all-wheel drive will help put the Hellcat engine's power to the ground in a more manageable way than the Charger and Challenger do through just the rear wheels. That means better acceleration times than the Dodges (11.0 seconds in the quarter-mile for the Charger Hellcat, 11.2 for its Challenger sibling).

Next-gen Jeep Wrangler to pack 300-hp Hurricane turbo four

Fiat Chrysler has been working for some time now on a new turbocharged four-cylinder engine. Dubbed "Hurricane," the engine is now said to produce nearly 300 horsepower. And its first application could be in the next-generation Jeep Wrangler. With that much power coming from such a small engine, the Hurricane would offer an even higher level of specific output than the 1.75-liter engine in the Alfa Romeo 4C – one of FCA's highest-stressed engines – far eclipsing the 4C's 120 horsepower per liter with 150 hp/l. By way of comparison, the latest 2.0-liter, four-cylinder version of Ford's EcoBoost engine produces "only" 245 hp (122.5 hp/l). The 2.0-liter turbo four in the latest Mercedes-AMG CLA45 and GLA45, however, produces 375 hp. To get so much out of so little an engine, FCA will utilize a twin-scroll turbocharger and variable valve timing. That could make it ideally suited towards a compact performance model, but according to Automotive News, its first application could be in the new the Wrangler. The larger 3.6-liter Pentastar V6 produces 285 hp, nearly as much as the Hurricane will. But with a smaller engine, an eight-speed transmission, and aluminum construction, the new Jeep will likely benefit from dramatically-improved fuel consumption. Related Video:
