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.

Jeep celebrates with 75th anniversary editions [w/video]

Jeep is celebrating its 75th anniversary this year. That's one heck of a milestone, and it's celebrating with a special edition. Not just one special edition, either. The all-American off-road brand has wheeled out six – one for each model in its lineup. Though the specifications for each of these 75th Anniversary Edition specials differs from model to model, they each feature an available green paintjob, wheels in a low-gloss bronze finish, orange trim, interiors upholstered in a unique mesh fabric, and (of course) special badges inside and out. They also each feature some manner of open-air aperture, from the fully convertible roof on the Wrangler through the fabric roof panel on the Renegade to the more conventional power sunroofs on the Cherokee, Grand Cherokee, Compass, and Patriot. The shades of green paint depend on the model. The Compass, Patriot, Cherokee, and Grand Cherokee offer Recon Green, the Renegade a brighter Jungle Green, and the Wrangler and Wrangler Unlimited can be had in Sarge Green. If you don't dig the verde approach, you can still order yours up in a different color. The Wrangler special naturally comes the most prepared for off-road duty, packed with rock-crawling equipment like Dana axles with a choice of axle ratios. For more details, you'll want to delve into the press release below, and for a closer look you can scope them out in the accompanying image gallery and video footage. The 75th Anniversary editions are set to hit dealers within the next few months, with prices starting at $22,475 (plus $995 destination) for the Patriot. This content is hosted by a third party.
