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.

2013 Jeep Wrangler Moab Edition

There will forever be a soft spot in my heart for the Jeep Wrangler. The last one I owned was red, and, as a 1990 model, had the square headlights derided by Jeep enthusiasts who grew up on the Civilian Jeeps that descended from their General Purpose military ancestors. As a teenager, I couldn't have cared less what shape its headlights happened to be - to me, a Jeep Wrangler represented freedom; a carefree do-it-all machine equally at home with the top stowed away in the summer or with the heater on full blast in the snowy clutches of Old Man Winter. In Dr. Seuss parlance, my square-headlighted Sneetch was just as worthy as any round-headlighted Sneetch.
All that said, I'll be the first person to advise against buying a Jeep Wrangler of any sort for owners who don't plan to use it as its makers intend. There's no good reason to punish yourself with a stiff and springy ride, a loud and somewhat drafty (though generally water-resistant) interior or the poor fuel economy expected of a block-shaped vehicle if you don't enjoy its other, more exciting benefits.
Of course, Jeep has done its darndest over the years to make the Wrangler as civilized as possible while keeping it as capable as federal law will allow. The 2013 Jeep Wrangler Moab edition is one of Jeep's latest attempts to attract attention from the upper reaches of the active lifestyle set, and I spent a week with one to see what makes the Moab special.

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.
