NHTSA closes investigation into Jeep Liberty fires

The investigation that the National Highway Traffic Safety Administration opened into the Jeep Liberty in October 2013 has been closed. NHTSA received two (!) complaints about fires starting in the driver's door, thought to be caused by the master power window switch. The initial estimate was that 80,000 Libertys could be roped into a possible recall, but according to a report in the Detroit News the agency examined records for 425,000 Chrysler products that used the same window switch, including the Dodge Nitro and Chrysler Town & Country minivan.
After canvassing 265 warranty claims related to the master switches, NHTSA concluded that the rate of fires compared to the "large population of vehicles" was rather low, and that there was no trend pattern behind the few issues it did find. Perhaps with that, and the closure of the trailer hitch investigation, the Liberty can finally rest in peace.

Jeep Cherokee won't get diesel until sales of oil-burning Grand Cherokee improve

Okay Jeep fans, you want more diesel options? Time to step up and prove it. The only way Jeep will offer a diesel powerplant in the Cherokee, according to brand head Mike Manley, is if sales of the Grand Cherokee EcoDiesel nearly double.
Currently, about eight percent of the Grand Cherokees sold feature the 3.0-liter, EcoDiesel V6. That's simply not enough to warrant the bringing an oil-burning Cherokee to the US market, despite the vehicle's presence in Europe, where it's sold with a 2.8-liter diesel V6.
"Cherokee is slightly different because of its weight and size. When I think about bringing Cherokee diesel here, I would like to see Grand Cherokee diesel get much higher than eight percent," Manley told Automotive News. "It would have to be in mid-double digits."

2018 Alfa Romeo Stelvio Quadrifoglio vs. 2018 Jeep Grand Cherokee Trackhawk: On-paper sibling rivalry

Pricing was revealed for the 2018 Alfa Romeo Stelvio Quadrifoglio, and with its $81,590 price tag, it's within range of yet another high-performance SUV from Fiat-Chrysler: the 2018 Jeep Grand Cherokee Trackhawk. The Hellcat-powered Jeep is more expensive than the Stelvio at $86,995, but depending on options, the price advantage might go either way. This left us wondering, how similar are these two high-powered SUVs? Besides sharing the same number of words in their very-long names, we took a look at some of their performance specs and put them in the spreadsheet below. As always, if you want to compare either of these with other speedy SUVs, be sure to try out our comparison tools. As far as outright speed, both SUVs are surprisingly close. The Trackhawk is just a bit quicker in a straight line, hitting 60 mph in just 3.5 seconds as opposed to the Alfa's 3.9. The Jeep's 180-mph top speed is also 3-mph quicker than the Alfa. But neither of these differences is especially huge. What makes this interesting is how different the paths each SUV takes to get to its results. The Trackhawk accomplishes the task with pure grunt. It has Dodge's Hellcat supercharged 6.2-liter V8 making 707 horsepower and 645 pound-feet of torque to overcome its hefty 5,363-pound body. The Alfa, on the other hand, makes do with less power and torque, 505 and 443, respectively, from its twin-turbocharged 2.9-liter V6. It has less weight, though. Exactly how much less we're not sure, since Alfa hasn't revealed that number, but a regular Stelvio weighs right around 4,000 pounds, so we would guess the weight is similar, possibly a little more. View 14 Photos The differences in how each SUV achieves its performance should result in pretty different driving characteristics, and probably different buyers. Each SUV's bragging points also indicates this. The Trackhawk boasts an impressive 11.6-second claimed quarter-mile time, something that American muscle car fans everywhere care about. The Alfa brags about how it's the fastest production SUV to lap the Nurburgring, something sure to impress fans of foreign cars and those that value handling over straight-line performance. So really, although these two SUVs have performance similarities, they're also very different, and the right one for you depends on what you value.
