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.

FCA recalling 63k Jeeps, Vipers and Ram ProMaster City vans

Fiat Chrysler Automobiles has announced a pair of recalls cover nearly 63,000 vehicles. The bigger of the two actions covers manual-transmission-equipped vehicles from 2006, including the Jeep Liberty and Wrangler, as well as the Dodge Viper. FCA engineers uncovered that the clutch ignition interlock switches use a kind of wire that was part of a previous recall campaign. Because of this, the company said that affected vehicles may not start, although in rare cases, "if recommended starting procedures are not followed," the affected vehicles may lurch forward after turning the key. Those recommended starting procedures "include activating the parking brake, placing the shift lever in neutral and pressing the clutch pedal before turning the vehicle's ignition key." Recall number two affects the company's 2015 Ram ProMaster City cargo and passenger vans. Owners will need to report to dealers to have a piece of tape removed from the side-curtain airbags. The tape is added during assembly and in some cases, may not have been removed. That could prevent the airbags from deploying in the event of a crash. Just under 59,000 vehicles are included in the first recall, including 43,874 in the United States, 11,309 outside of North America, 2,944 in Canada and 706 in Mexico. The ProMaster City recall includes just over 3,900 vehicles. FCA claims it's unaware of any injuries, fatalities or accidents related to either recall and will perform repairs free of charge. Scroll down for the official press release on both campaigns.

The Company will replace their clutch ignition interlock switches at no charge to customers. The action follows an investigation by FCA US engineers that discovered these vehicles are equipped with switches that contain a certain type of wire implicated in a previous campaign. The wire, which was temporarily substituted by a supplier for the specified material, may break. As a result, the vehicles may not start, and in rare cases – if recommended starting procedures are not followed – a vehicle may exhibit unintended movement when its ignition key is turned. FCA US is unaware of aware of any related injuries or accidents involving this population of vehicles.

Jeep in St. Louis hacked from Pittsburgh

One of America's most popular vehicles contains a security flaw that allows hackers to remotely commandeer it from anywhere on the planet. Cyber-security researchers Chris Valasek and Charlie Miller say they've accessed critical vehicle controls on a 2014 Jeep Cherokee that allowed them to remotely control critical vehicle functions like braking, transmission function, and steering. Automakers have downplayed the possibility a car could be remotely compromised, but the significance of the findings detailed Tuesday could cause them to reevaluate the threats posed to hundreds of thousands of vehicles already on the road. A key finding – the pair needed no physical access to the Jeep to pull off the attack. Valasek and Miller accessed the controls via a security hole in the Sprint cellular connection to Chrysler's UConnect infotainment system. In the course of their research, Valasek sat in his Pittsburgh home and remotely manipulated Miller's Jeep as he drove along a highway outside St. Louis. If you know a car's IP address, they say, a hacker could control it from anywhere. "We didn't add anything, didn't touch it," Valasek told Autoblog. "A customer could drive one of these things off a lot, and they'd have no clue it had these open attack surfaces." Remotely, he disabled brakes, turned the radio volume up, engaged windshield wipers and tampered with the transmission. Further, they could conduct surveillance on the Jeep, measuring its speed and tracking its whereabouts. They conducted the experiments over multiple breaches. They made their findings public on the same day the National Highway Traffic Safety Administration, the federal agency in charge of vehicle safety, released its latest report on the readiness of government and automakers to fend off these sorts of cyber attacks. Later today, two US Senators are expected to introduce legislation that would help consumers better understand the potential risks of car hacking. In the early stages of their research, Valasek and Miller found a security flaw in the car's wi-fi that allowed them to remotely manipulate controls from a range of about three feet. But in recent months, they found another vulnerability in the Sprint cellular connection in the UConnect system. That was a key breakthrough. "Lo and behold, we found we could communicate with this thing using cellular, and then more research, and 'Holy cow,' we're using the Sprint network to communicate with these vehicles," Valasek said.
