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 recalling 630k Jeep models worldwide

Despite its refusal to recall 2.7 million Jeep Grand Cherokee and Liberty models this week over a gas tank fire risk, Chrysler will be recalling 630,000 Jeep Compass (pictured), Patriot and Wrangler vehicles around the globe for a pair of entirely different reasons.
The affected Compass and Patriot models are all from the 2010 to 2012 model years - 254,000 in the United States, 45,400 in Canada and 109,000 elsewhere in the world. In these models, a software error may result in the late deployment of the side airbags and seatbelt tensioners. In the event of a crash, failure of these systems could result in more serious injuries for the vehicle's occupants.
Jeep's go-anywhere Wrangler also faces a separate recall due to power steering fluid lines that can possibly wear a hole in the transmission oil cooler line. According to Chrysler, the vehicles could then leak fluid, possibly damaging the transmissions. Roughly 221,100 Wrangler models are being recalled because of this issue, all of which are fitted with Jeep's 3.6-liter Pentastar V6 engine. In the US, 181,000 vehicles are affected, with an additional 18,400 in Canada and 21,700 additional units worldwide. A Chrysler spokesperson said that no crashes or injuries have been reported with either case, according to the Associated Press.

Some Jeep Cherokees and Chrysler 200s to get standard stop-start in 2015

Automakers the world over are striving to find ways to make their models more efficient, and Chrysler has a solution for some versions of the 2015 Chrysler 200 and 2015 Jeep Cherokee (2014 model shown). The Tigershark 2.4-liter four-cylinder in the 200 and the 3.2-liter Pentastar V6 in the Cherokee are getting a slight boost later this year thanks to the addition of Chrysler's Engine Stop-Start system as standard equipment. The company predicts modest gains - a three-percent improvement in fuel economy and a three percent reduction in CO2 emissions with the new tech compared to without it. While it's not much, those who sit in traffic a lot may see a difference.
Chrysler's stop/start system uses a high-speed starter motor to restart the vehicle in a claimed a third of a second. It works by detecting when the vehicle comes to a stop and turning off the engine. A more powerful battery maintains all of the model's accessories while it sits. When the driver lets off the brake, the car starts up again to drive away. There is even a button in the cabin to turn the ESS off, if desired.
The Jeep will be the first to receive ESS in the third quarter of this year to coincide with the start of production of the 2015 model-year version. The 200 will follow in the fourth quarter as a rolling change in production.
