Jeep Liberty under investigation for door fires

The Jeep Liberty has already had plenty of attention for possible fires thanks to the first-gen model's fuel tank, but now the midsize Jeep is under the microscope of the National Highway Traffic Safety Administration for another fire-related concern. NHTSA has opened an investigation for the 2012 Liberty after receiving two reports of electrical fires in the driver's door.
According to the investigation summary, around 80,000 vehicles could potentially be affected by this problem. In both reported fires, the drivers noticed smoke and then flames from the master power window switch, and they had to pull to a stop and exit through the passenger side of the SUV. According to Autoguide, there was one injury to a motorist who suffered burned fingers while trying to open the driver's door.
Interestingly, the Dodge Nitro is not yet involved in this investigation, even though it was still around for the 2012 model year; the Nitro ended production in 2011 about a year before the final Liberty rolled off the line for the 2013 model year.

Watch this 840-hp Jeep Grand Cherokee SRT8 walk away from GT-Rs and M3s

This last-generation Jeep Grand Cherokee SRT8 does things that SUVs just shouldn't be able to do, like win drag races against tuned Nissan GT-R and BMW M3 coupes. Granted, the owner isn't coming into this fight with a stock Jeep – far from it. In addition to twin turbos whistling away, he says the engine is a 449-cubic-inch V8, which is nearly 7.4 liters of displacement. As it runs here, the driver claims that the turbos are pumping out around 14 psi of boost to give an estimated 840 horsepower. What's more, he further maintains the powertrain could reach around 1,200 hp with things fully cranked up. Even somewhat dialed back, this Jeep is ready to take on a breadth of formidable challengers, including a couple of Chevrolet Corvette models and a Lamborghini Aventador. Check out the video to see how this menacing Grand Cherokee fares in a day at the races.

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).
