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. Scroll down for the official NHTSA investigation summary.

NHTSA investigating power modules on Chrysler Group SUVs and minivans

The Center for Auto Safety is officially petitioning the National Highway Traffic Safety Administration to begin scrutinizing alleged problems with the totally integrated power module (TIPM) on about 24 Chrysler Group SUVs and minivans. The advocacy group claims that the part's failure can cause affected vehicles to stall or not start at all. NHTSA is still looking into the accusations and deciding whether a full investigation is actually warranted.
The CAS petition claims at least 70 TIPM failures, but according to NHTSA, six of the complaints are for models that don't have the modules. In 34 of the reported cases, the vehicles refused to start, and in 17 of them the engine stalled. There were also two allegations of smoke and one of a fire. However, none of these affected airbag deployment or resulted in a crash.
This petition isn't the first TIPM-related problem for Chrysler Group. A recent report in the New York Times alleged that it found 240 complaints potentially related to the issue on NHTSA's website alone. In September, the automaker also recalled 230,760 examples worldwide (188,723 in the US) of the 2011 Jeep Grand Cherokee and Dodge Durango replace the fuel pump relay circuit inside of the TIPM-7 with one external to the unit. The original part could allegedly cause the models to stall without warning. Even earlier, the company also recalled about 80,000 examples of the Jeep Wrangler and Dodge Nitro in 2007 to have the module reprogrammed.

SUV lifts you up where you belong and leapfrogs traffic jams

So, you're at a dead stop, stuck in traffic, when it pulls up behind you. It appears to be a garden-variety Jeep Grand Cherokee. That is, until its undercarriage lifts the Jeep 9 feet into the air, and the whole rig straddles you and the cars ahead of you in a bid for open road. The car is called the Hum Rider, and no, you can't buy one at the Jeep store. It's a one-off publicity stunt intended to promote Verizon Telematic's Hum platform, which plugs into a car's OBD port and for $10 a month provides vehicle diagnostics, roadside assistance, location tracking, and speed and geo-fencing alerts. (Not sure if Hum tracks vertical leaps.) Verizon enlisted viral marketing agency Thinkmodo to promote the Hum, and this idea was head and shoulders above the rest. "We saw this one [and said], 'Wow, that is crazy,' said Jay Jaffin, Verizon's VP of marketing. "We loved the idea." Thinkmodo co-founder James Percelay told Mashable that they wanted to represent the upgrade Hum brings to cars. So the car goes up. Get it? Here's the star of this story: Hum Rider's designer, Scott Beverly, has done visual effects for Hollywood in The Dark Knight, Inception and Interstellar. He works for A2Zf, a Lancaster, Calif., design and engineering firm that keeps the world filled with Batmobiles, Red Bull Can Cars and beautifully designed VWs and Audis. A2Zf has also worked with NASA on X-planes and with Northrup on the B2 bomber, so compared to those projects, a car-straddling car is hardly a stretch. So what does it take to make a car do this? How about: Over 300 feet of hydraulic lines that operate everything - the lift mechanism, steering, braking and power to the drivetrain. A gas-powered Honda generator under the hood that powers hydraulic pumps pushing out 900 pounds of pressure. A lot of mechanical structure. Hum Rider weighs 8,500 pounds, almost double a standard Grand Cherokee. Heavy-duty truck tires to support all that weight. Four undercarriage cameras that allow the driver to see and clear what's beneath him. What did it cost? They're not saying. What would it be worth, the next time you're stuck in traffic? Priceless.
