JL Jeep Wrangler experiencing death wobble, NHTSA checking into it

The redesigned 2018 JL Jeep Wrangler is selling remarkably well, but it looks like it's still susceptible to age-old Jeep solid front axle vehicle issues. Recently, the NHTSA has received 11 JL Wrangler-specific complaints for a problem referred to as "death wobble" in the Jeep community. It's currently looking into the complaints to see if further action is necessary. Death wobble is a term used predominantly by Jeep and specifically Wrangler owners to describe a violent steering wheel oscillation, typically caused by hitting some form of bump or pothole at higher speeds. For it to occur, there has to be something loose or damaged within the front steering or suspension system. The death wobble gets its name, because the vibrations through the steering wheel are far more frightening than any kind of a wheel imbalance problem. However, using the word "death" would be a misnomer as well, because there are no reported deaths due to the issue over decades of Jeeps experiencing the issue. A little over a month ago, FCA decided it needed to recall 18,000 JL Wranglers because of a faulty weld around where the track bar is welded to the frame. As of now, there's no evidence linking this faulty weld with death wobble (an FCA spokesperson told us as much), but one of the most common causes of death wobble is a track bar issue. If a bad track bar weld is your problem, you're in far worse shape than any death wobble, because you'll end up with a complete loss of steering. We asked Jeep about death wobble and a company spokesperson said that it "is not a widespread condition, nor is it a safety issue." FCA also said most of the incidents are linked to poorly installed suspension modifications, such as a lift-kit. However, the most current complaints for JL Wranglers describe unmodified and recently purchased vehicles. This means some vehicles still experience the issue despite being stock Wranglers. For now, if you experience the death wobble in your new Jeep, it's best to slow down immediately in a safe place. Most are taken by surprise by the sudden oscillations from the wheel, but you should still be able to control the car. FCA says that even if you do experience the issue, it is routinely corrected on its own. We'll keep tabs on this, and update if there are any developments. Related video:

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.

Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.
