Fiat Chrysler recalls 4.8 million U.S. vehicles for cruise control defect

WASHINGTON - Fiat Chrysler said on Friday it is recalling 4.8 million U.S. vehicles over a defect that could prevent drivers from deactivating cruise control and warned owners not to use the function until they get software upgrades. The Italian-American automaker said no injuries or crashes are related to the large recall campaign but said it had one report of a driver of a 2017 Dodge Journey rental car unable to deactivate the cruise control. Fiat Chrysler, which in 2015 was hit with penalties from U.S. regulators totaling $175 million for safety lapses, did not say how much the recalls would cost. The recall addresses what Fiat Chrysler called an "extremely rare" series of events that could lead to drivers being unable to cancel cruise control. The National Highway Traffic Safety Administration (NHTSA) said on Friday it "strongly encourages vehicle owners to follow a warning" to stop using cruise control on the recalled vehicles until repaired. NHTSA said drivers could overpower the system by forcefully applying the brakes until the vehicle stopped. Fiat Chrysler also said the vehicle could be stopped by shifting into neutral and braking. Fiat Chrysler shares fell more than 2 percent in premarket trading in New York on the recall. Fiat Chrysler noted that at times cruise control systems automatically initiate acceleration to help vehicles maintain driver-selected speeds, including when going up an incline. If an acceleration occurs simultaneously with a short-circuit in a specific electrical network, a driver could be unable to deactivate the function. Fiat Chrysler said vehicles may be placed in park once stopped, at which point cruise-control is canceled. The recall involves a group of gasoline-powered vehicles with automatic transmissions from various model years built from 2014 through the 2019 model year. Most of the vehicles being recalled cover the 2014-2018 model years. Among the vehicles being recalled are the Chrysler 200, Chrysler 300, Chrysler Pacifica, Dodge Charger, Dodge Challenger, Dodge Journey, Dodge Durango, Jeep Cherokee, Jeep Grand Cherokee, Jeep Wrangler and Ram 1500, 2500 and 3500 pickup trucks and Ram 3500/4500/5500 cab chassis trucks. Fiat Chrysler made the announcement going into the busy Memorial Day weekend, which traditionally kicks off the summer driving season.

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).
