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.

Lexus gets top brand marks from Consumer Reports; Ford, Jeep hit hard

Consumer Reports has released its 2014 Car Brand Report Cards, with Lexus again reigning at the top and doing so with the same industry-topping score of 79 that it registered in last year's Report Cards. This year, the institute credited its lineup for being "usually quiet, comfortable, and fuel-efficient," noting it's the only brand on the list "to achieve an excellent average overall reliability score." The Car Brand Report Cars list is meant to rank the best all-around vehicles based on CR testing and reliability results tallied by subscribers it surveyed. Each brand included must have sufficient test and reliability data for at least three models, a standard which left out 11 marques including Fiat, Jaguar, Land Rover and Porsche.
This 2014 Brand Report Cars edition is the first of a new format in which sub-brands have been broken out from their parent brands, with Acura using this year to move up the leaderboard into second place with a score of 75 for its "reliable, well-finished and somewhat sporty models." The top three was rounded out by Audi, climbing from eighth to third by scoring a 74 for "well-crafted interiors, nice handling and good gas mileage." Audi scored highest in the road-test portion, its improved reliability aiding its rise. The top nine was completed by Subaru, Toyota, Mazda, Honda, Infiniti and Mercedes-Benz.
Ford and Jeep weighed in at the other end of the rankings, Jeep taking the lowest overall score in the road tests and hampered by "a mix of spotty reliability." Ford was sunk by reliability issues with its MyFord Touch infotainment system which consumers found troublesome enough to negate its cars earning "solid test scores" for being "very nice to drive." Perhaps the rumored switch from Microsoft to Blackberry's QNX for the next generation SYNC will help them out. Cadillac's score also took a hit for infotainment reasons after it was the leading US brand last year, the CUE system in the XTS dragging Cadillac to the bottom of all General Motors brands.

Chrysler axes old V6s, goes all-Pentastar

Old technology has a way of lingering on, particularly at Chrysler headquarters in Auburn Hills. So while the Pentastar V6 has replaced the older engine architecture in just about every application, it still soldiered on in some export markets. But the introduction of a new 3.0-liter Pentastar V6, produced in Michigan and meant only for the Chinese market, has put the final nail in the old engine's coffin.
Fitted into the 2014 Jeep Grand Cherokee and Jeep Wrangler just introduced to China at the Chengdu Motor Show, the downsized six uses the same architecture as the larger 3.6-liter Pentastar V6. But because of its 2,997cc capacity, it can be exported to China without the increased duty the 3.6-liter or even 3.2-liter Pentastar engines would incur. The 3.0-liter V6 develops 230 horsepower at 6,350 rpm and 210 pound-feet at 4,400 rpm.
Admittedly, it's unlikely, but even though the engine was said to be created solely to undercut tax thresholds in China and Europe, the 3.0-liter Pentastar has recently surfaced in rumors of an application here: as the boosted heart of a potential Cherokee SRT with anywhere from 375 to 410 hp.
