2.1 million vehicles recalled again over faulty airbags

Fiat Chrysler Automobiles, Honda and Toyota will recall 2.1 million vehicles to fix faulty airbag modules "after the manufacturers' original attempts to fix the defects proved ineffective in some vehicles." These vehicles had all previously been recalled, but the National Highway Traffic Safety Administration found that the airbags could still potentially malfunction. This recall will cover Acura MDX, Dodge Viper, Jeep Grand Cherokee, Honda Odyssey, Pontiac Vibe, Toyota Corolla, Toyota Matrix and Toyota Avalon models made in the early 2000s. NHTSA has reportedly received about 40 reports of airbag deployment in such vehicles, even though the vehicle had not been involved in a crash. Roughly one million of these same vehicles, all from Honda and Toyota, are also subject to recalls due to faulty Takata airbag modules, though this particular recall is for "an electronic component manufactured by TRW" that is separate from the actual airbags from Takata. According to NHTSA Administrator Mark Rosekind: "This is unfortunately a complicated issue for consumers, who may have to return to their dealer more than once. But this is an urgent safety issue, and all consumers with vehicles covered by the previous recalls should have that remedy installed. Even though it's a temporary solution until the new remedy is available, they and their families will be safer if they take the time to learn if their vehicle is covered and follow their manufacturers' instructions. A hassle is much better than a family tragedy." If you're the owner of an affected car, expect to hear more from the official automaker and government channels in short order. In the meantime, we'd suggest getting your car checked and fixed at your local dealer. The official statement and recall information can be found below. Previously Recalled Vehicle Remedies Not Working as Designed; NHTSA Announces Follow up Recall of 2.12 Million Cars and SUVs Saturday, January 31, 2015 Contact: Gordon Trowbridge, 202-366-9550, Public.Affairs@dot.gov WASHINGTON – U.S. Transportation Secretary Anthony Foxx announced today the recall of more than 2.12 million Acura, Dodge, Jeep, Honda, Pontiac, and Toyota vehicles for a defect that may cause airbags to deploy inadvertently. The recalls will provide vehicle owners with a new remedy after the manufacturers' original attempts to fix the defects proved ineffective in some vehicles.

Here's what it'll take to build a Jeep Grand Cherokee Hellcat

Let's get one thing straight: We want a 707-horsepower Grand Cherokee Hellcat to happen. Badly. The latest report from Motor Authority is encouraging; the bonkers SUV supposedly has a codename, Project K, and has been given the green light for production. Fingers crossed. You might be wondering why the Trackhawk isn't already a thing. Hellcat engines exist, SRT Grand Cherokees exist, so just combine the two, right? It's not quite that easy. Here, we outline what needs to happen, why it should be the quickest Hellcat vehicle out there, and why it won't come anywhere near 200 miles per hour. How To Build A Hellcat Jeep The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged V8. The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged Hellcat V8. Breathing is important on two counts: pulling in enough air for the combustion to put out 707 hp, and then cooling the various heat exchangers once the engine is up to temperature. Dodge did it with the Charger and Challenger, it can do it with the Jeep. This is one place where the Grand Cherokee's larger frontal area might be a boon, as it gives the engineers more surfaces through which to suck air. Once you generate the 707 horsepower and 650 pound-feet of torque, it has to get to the wheels somehow. Jeep's current SRT all-wheel-drive system will at least need some beefing up to handle the torque. It could require a more complete re-engineering. We at least know the ZF-supplied eight-speed auto, used in the Dodge Hellcat models, is up to the task. The Hellcat engine should fit in the Grand Cherokee, as it's about the same size as the 6.4-liter currently in SRT Jeeps, but the Hellcat is taller because of its supercharger. The hood may need to be raised or at least resculpted for clearance, as well as to address those cooling needs. Quicker Than Everything, But Not Faster 200 mph? We're skeptical, from both a physics standpoint and a legal one. A reminder of the quick/fast distinction: quick is acceleration, fast is road speed. The Jeep's all-wheel drive will help put the Hellcat engine's power to the ground in a more manageable way than the Charger and Challenger do through just the rear wheels. That means better acceleration times than the Dodges (11.0 seconds in the quarter-mile for the Charger Hellcat, 11.2 for its Challenger sibling).

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.
