Jeep Renegade's development a template for new Fiat Chrysler Auto

"We figured we'd take the best of both worlds." - Ralph Gilles.
The international makeup of the 2015 Jeep Renegade will serve as a template for cooperation within the newly formed Fiat Chrysler Automobiles, Senior Vice President of Product Design Ralph Gilles said.

Jeep Wrangler diesel likely after 2015 model refresh

We automotive journalists aren't always the right people to ask about whether a US-spec vehicle should or should not be offered with a diesel powertrain (hint: the answer is usually "YES"). But when it comes to the iconic, off-road-ready Jeep Wrangler, we aren't the only ones who have been clamoring for an oil-burning engine behind that famous seven-slat grille. To that end, it appears there's good news on the horizon, as Jeep CEO Mike Manley recently told Ward's Auto that the "Wrangler is on the radar to get (a) diesel."
"I'm confident that the Grand Cherokee will show just how large a demand there is for diesel, and I think what that will do is reinforce the need for us to target Wrangler as a vehicle that can take a diesel," Manley told Ward's. The most rugged of Jeeps is scheduled to get an overhaul around 2015-16, and the diesel powertrain will likely be introduced around that time.
This year alone, Chrysler will be adding a diesel engine to the Grand Cherokee SUV, as well as the Ram 1500 pickup and Promaster utility van.

100,000 Jeep Cherokee models subject to further 9-speed recalibration

It seems that the software problems with the nine-speed automatic gearbox in the Jeep Cherokee continue to mount. The programming already caused multiple development delays and even postponed the Cherokee's market launch by roughly two months. Now, Jeep has issued another recalibration to hopefully assuage unhappy drivers.
According to Automotive News, this reflash for the allegedly jerky transmission covers over 100,000 Cherokees built before May 5, but it's not technically a recall. If owners are having problems and complain to the dealer, they get the new software. Otherwise, they continue with the current version. New vehicles on dealer lots also receive the latest revision to the programming. It takes only around five minutes to install, but technicians need to take the Cherokee on a test drive to adapt the gearbox to the changes.
The Cherokee's transmission software has been problematic practically since the beginning. The Jeep plant in Toledo, OH, briefly idled its second-shift workers last year to take care of the issue. Since the launch issues for the crossover, demand has been strong. Jeep added another 1,000 temporary workers to the Toledo factory to keep up, and sales were on par with the Wrangler in just its first two months.
