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.

Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.

Chrysler Recalling Nearly 907,000 Cars, SUVs

Nearly 907,000 Chrysler, Dodge and Jeep SUVs and cars are being recalled for alternators that can fail and heated power mirror wiring that can short and cause minor fires. The recalls, posted Thursday by U.S. safety regulators, push the total number of recalls so far this year 544, totaling a record of more than 52 million vehicles. The largest of Thursday's recalls covers nearly 470,000 Jeep Grand Cherokees, Chrysler 300s, and Dodge Chargers, Challengers and Durangos from the 2011 through 2014 model years. The alternators can fail, causing the 3.6-liter V6 engines to stall unexpectedly. The problem also can cause the electrical system to fail, as well as knock out power-assisted steering, antilock brakes and electronic stability control. It can even cause fire or smoke, according to documents Chrysler filed with the U.S. National Highway Traffic Safety Administration. NHTSA opened an investigation into the problem in July, and Chrysler began its own probe in August. The company analyzed warranty complaints and alternators that had failed. The alternator generates electricity to recharge the battery and run other devices. Chrysler investigators traced the problem to heat fatigue in an alternator diode. Chrysler said it received 322 complaints about the problem, while 55 people complained to NHTSA. The company said it knows of one crash related to the problem, but no injuries or fires. The company will replace the alternators with upgraded versions for free. Owners will be notified in November. The company says customers who see warning lights or suspect a problem should contact their dealers. The recall affects cars and SUVs sold mainly in the U.S. and Canada, but some were sold in Mexico and overseas markets. The second recall covers almost 437,000 Jeep Wranglers from 2011 through 2013. Water can find its way into the heated power mirror wiring harness and cause corrosion. That can cause a short and could cause a minor fire and smoke, as well as cause loss of function of the mirror. The problem was discovered in February after three Wranglers in Canada were damaged. Chrysler says it has 26 complaints about the problem, but it knows of no fires, crashes or injuries. Dealers will move the wiring and install a protective shield to keep water out at no cost to owners, starting in December. Most of the Wranglers are in the U.S., Canada and Mexico, but more than 78,000 were sold overseas.
