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 rear-mounted fuel tank controversy

2014 Jeep Cherokee musters 22 MPG city, 31 highway

Production and media drive delays included, there has been no lack of press surrounding the 2014 Jeep Cherokee. With the most recent delay reportedly due to powertrain calibrations, we've been waiting to see how the Cherokee's fuel economy looks against the highly competitive compact CUV segment. Thanks to the EPA, we now know the fuel economy figures for the newest member of the Jeep family.
Arguably, the Cherokee has the most modern powertrain in its class with an updated base engine, all-new V6 and all-new nine-speed automatic transmission, but its fuel economy figures are simply on par for the segment. Still nothing to scoff at, though. According to fueleconomy.gov, front-wheel-drive Cherokee models with the base four-cylinder mill will top out the lineup with 22 miles per gallon in the city and 31 mpg on the highway; opting for four-wheel drive with this engine drops the figures to 21 city and 28 highway. Get even crazier with the option list, and the new 3.2-liter Pentastar V6 will get you 19 mpg city and 28 mpg highway in two-wheel-drive form or 19 city and 27 highway for 4WD.
If you're wondering how that stacks up among compact CUVs, head on over to Automobile Magazine for a full fuel economy breakdown for the segment. The controversially styled crossover hits dealers this month, and we'll be driving it in just a couple of weeks.
