Chrysler is facing some production problems with their new 2014 Jeep Cherokee model that was supposed to go on sale September 30. The new Jeep models have been plagued with some “recalibration” issue with the new nine speed transmissions mated to the Jeep’s standard four cylinder engine according to two Chrysler spokesmen. The “recalibration” issues have idled 500 Chrysler workers at their Toledo Jeep plant. The new Jeeps replace the Jeep Liberty model and are built on a Fiat designed platform. They offer 22-31mpg fuel economy, which is substantially better than the early AMC-Jeep designed Cherokee models that only offered mileage in the teens with their 4.0 liter six cylinder engines. The new Cherokees should start at $22,250, however the larger model Jeep Cherokees will range in prices up to $47,000, with the larger models offering larger engines than the smaller Cherokee models. A new V6 engine option will also be available for new smaller Cherokee models.
