Jeep reveals annual Moab Easter Jeep Safari concepts

Jeep has unveiled its annual spate of concepts before the Easter Jeep Safari. Those start with the Grand Cherokee Trailhawk Concept (below left), complete with the company's EcoDiesel V6 engine. Designers threw in a set of 35-inch Mickey Thompson tires wrapped around 17-inch Rubicon wheels, and a set of custom fender flares help keep all that rubber under wraps.
Meanwhile, the Wrangler Mopar Recon (below right) packs a 6.4-liter Hemi V8 good for 470 horsepower. All that grunt gets to the ground via a five-speed automatic transmission and a set of a Dana 60 axles frond and rear with 4.10 gears. The Recon also makes use of a 4.5-inch prototype long-arm kit and a set of prototype eight-lug bead lock wheels.
The Wrangler Stitch (below left) builds on the momentum of the Wrangler Pork Chop Concept. Engineers once again set out to strike as much weight as possible from the vehicle, and actually managed to trim the curb weight down to 3,000 pounds. That effort has given the machine the same power to weight ratio as the Grand Cherokee SRT8. Plenty of carbon fiber, door deletes and a chrome moly roll cage all help trim those pounds, and a set of DanyTrac Pro Rock 44 axles with 4.88 gears and ARB lockers front and rear let this machine scramble over whatever is in its path.

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.

What's really going on with the 2014 Jeep Cherokee's transmission issues?

On September 23, Automotive News reported that Chrysler had idled the second shift workers it hired just five weeks prior at its Toledo Assembly Complex to build the 2014 Jeep Cherokee. At the time, Chrysler said it had "built the critical number of vehicles we need to stock dealerships once containment is released" and did not want "to put additional strain on our logistics partners ... upon release." That reasoning was not only unusual, it didn't seem to make sense.
It appears the center of the nine-speed issue is software, not hardware.
That same day, the Detroit News ran a piece claiming workers at the Toledo factory said the halt was due to issues with the Cherokee's transmission. It put the number of already-built Cherokees needing fixes at 1,000 and said that some of the workers not laid off had been instructed "to take the Jeep on long test-drives." That made more sense. Three days later, on September 26, Automotive News reported that the 500 workers laid off had been reinstated, with engineers "speeding repairs on the SUV's powertrain software." The AN piece didn't put a number on how many units are being fixed, but it did say that 12,000 have been built and are awaiting delivery to dealers. The best it could say about when dealers will get them, however, is that "progress on a fix is being made. It's unclear when shipments to dealers will start."
