Chrysler recalling 644k more Dodge Durango and Jeep Grand Cherokee SUVs over brakes

Early last month, we reported on Chrysler issuing a preemptive, proactive recall for about 25,000 units of the Jeep Grand Cherokee and Dodge Durango. The issue revolved around a brake system that wasn't causing any actual problems, but delivered an unsatisfactory brake feel, so Auburn Hills called in a good 25,000 of SUVs around the world, including 18,700 in the United States.
Now Chrysler, having apparently determined that the brake problem on its sport utes is actually much bigger than it initially realized, has drastically broadened the scope of the recall. As a result, the National Highway Traffic Safety Administration has issued a recall for precisely 655,354 examples of the Grand Cherokee and Durango, covering the 2011 through 2014 model years. In addition, Chrysler is recalling 42,380 units in Canada, 21,376 in Mexico and 159,685 overseas.
The problem which Chrysler found revolves around the brake booster, whose center shell has been found to be subject to corrosion, allowing water to get into the brake system. That water in turn could freeze, preventing the brakes from working as well as expected.

Chrysler axes old V6s, goes all-Pentastar

Old technology has a way of lingering on, particularly at Chrysler headquarters in Auburn Hills. So while the Pentastar V6 has replaced the older engine architecture in just about every application, it still soldiered on in some export markets. But the introduction of a new 3.0-liter Pentastar V6, produced in Michigan and meant only for the Chinese market, has put the final nail in the old engine's coffin.
Fitted into the 2014 Jeep Grand Cherokee and Jeep Wrangler just introduced to China at the Chengdu Motor Show, the downsized six uses the same architecture as the larger 3.6-liter Pentastar V6. But because of its 2,997cc capacity, it can be exported to China without the increased duty the 3.6-liter or even 3.2-liter Pentastar engines would incur. The 3.0-liter V6 develops 230 horsepower at 6,350 rpm and 210 pound-feet at 4,400 rpm.
Admittedly, it's unlikely, but even though the engine was said to be created solely to undercut tax thresholds in China and Europe, the 3.0-liter Pentastar has recently surfaced in rumors of an application here: as the boosted heart of a potential Cherokee SRT with anywhere from 375 to 410 hp.

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.
