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.

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.

Jeep Grand Cherokee, Dodge Durango still catching fire after recall

Automakers issue recalls all the time. It's part of the cost of doing business. We just assume that once the recall has been carried out, the problem in question has been fixed. But that's not always the case, as this latest investigation being undertaken by the National Highway Traffic Safety Administration goes to show. The problem stems back to a recall issued by Chrysler last summer. It revolved rather the sun visor in the SUVs it makes at its Jefferson North Assembly Plant – specifically, the screw affixing the sun visor could end up rubbing against the wiring for the lamp in the vanity mirror, potentially causing an electrical short and even a fire. 62 such short circuits, 38 fires and three injuries reported, prompting Chrysler to recall nearly 900,000 units of the 2011-2014 Jeep Grand Cherokee and Dodge Durango (over 650,000 of them in the United States). The plastic spacers they installed to rectify the problem, however, may not have done the trick. Eight reports (but none involving injuries) have been filed with the NHTSA regarding the same issue recurring, spurring the government agency to open a new investigation into the matter. If deemed necessary, the NHTSA could ask FCA to issue another recall to fix the issue again, which we may necessitate the installation of a fuze to prevent any such the electric short.

The recall was in response to the Office of Defects Investigation (ODI) investigation EA14-001 during which data provided by Chrysler indicates that the fire is caused by an electrical short in the vanity lamp wiring for either one of the sun visors mounted on the vehicle. The sun visors are mounted to the roof of the vehicle through the headliner with three metal screws.
