NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.

Updated 2014 Jeep Grand Cherokee ace same controversial moose test it failed in 2012 [w/video]

Some background: one of the more scandalous international incidents of he-said/he-said from 2012 was when Swedish magazine Teknikens Varld put the Jeep Grand Cherokee through its "moose (or elk) test" and reported that the SUV nearly rolled over. That lead to a whole lot of accusations and rebuttals: more than one website and Chrysler's own blog reported that the Jeep was overloaded; Chrysler said Teknikens printed the magazine then let Chrysler respond, Teknikens answered all of the charges in a lengthy post and said Chrysler was given a chance to comment before it went to print; when Chrysler sent investigators to oversee the test and the Jeep didn't go up on two wheels as it did in the first test, furthermore all four wheels stayed on the ground when Auto Motor und Sport tested a Grand Cherokee in the same way.
Teknikens then re-ran the test with a new vehicle and said it's been doing this test since the 1970s, uses the loading information that Chrysler provides to the Swedish motor authority and the previous Grand Cherokee passed with no problem. In the second test, the Jeep failed again, then it gave Chrysler engineers access to the car's electronics and ran the test again. In that second round the Grand Cherokee didn't repeat the lurid two-wheel action, but in eleven runs it blew out front left tire seven times. Chrysler still objects to the results of all of those tests and maintains that vehicle was safe.
The 2014 Grand Cherokee was given its shot at the gauntlet in the latest round of moose tests, and Teknikens Varld reports that it passed without any problem at all, its stability control working perfectly, controlling motion at low speeds and all the way up to 44.1 miles per hour. You can watch the video of the new test and read the press release from the magazine on the updated Grand Cherokee below.

NHTSA closes book on Jeep 'trailer hitch' recall after all

After much debating and hand-wringing, the National Highway Traffic Safety Administration now says it has "no reservations" with Chrysler's plan to recall certain Jeep Liberty and Grand Cherokee models over concerns that their fuel tanks, which are located behind the rear axle, could rupture or leak in the event of a rear impact. The longstanding argument between the two entities saw Chrysler openly defy the Feds after a request to recall 2.7 million units back in June.
Chrysler's "voluntary campaign" will instead see it recall 1.56-million 1993-2004 model year Grand Cherokee SUVs, along with 2002-2007 Liberty models. Affected vehicles will get a trailer hitch installed free of charge, which Chrysler says will provide an additional degree of protection for the fuel tanks in the event of a crash. Jeeps with Mopar-branded hitches or hitches that were installed at the factory aren't affected by this recall.
Chrysler's argument throughout this battle has been that the Jeeps in question are no more susceptible to fires than comparable vehicles from the same time period, a position that NHTSA has seemingly arrived at as well. "Those vehicles performed at a rate similar to their peers. That is the keystone analysis as to whether something poses an unreasonable risk to safety," said outgoing NHTSA boss David Strickland during an interview with the The Associated Press.
