Government Ending Jeep Investigation

The government is closing its investigation into older-model Jeeps with fuel tanks that could rupture and cause fires. The National Highway Traffic Safety Administration said Friday it has "no reservations" with Chrysler Group's plans to recall the vehicles. The agency is expected to release a report on its investigation in a few weeks. The decision ends an unusually public struggle between Chrysler and NHTSA. The agency asked Chrysler to recall 2.7 million Jeeps last June, contending that their gas tanks - which are positioned behind the rear axle - were at risk of rupturing and catching fire in rear-end crashes. Involved were Grand Cherokee SUVs from the 1993 to 2004 model years and Liberty SUVs from 2002 to 2007. Chrysler initially refused to recall the vehicles. The company said the rate of fuel leaks and fires after crashes was similar to comparable vehicles that were sold during the time in question. It was the first time in two years that an automaker had refused NHTSA's request for a recall. Chrysler later agreed to recall 1.56 million of the Jeeps and install trailer hitches on them to help protect the gas tanks. The company sent notices to the remaining customers saying their vehicles were fine if they have factory-installed or Chrysler-made trailer hitches. NHTSA said late Friday that it has been in close contact with Chrysler and will monitor the recall as it continues. Chrysler has told customers that it will start installing the hitches soon. "Consumers should have their vehicles serviced promptly once they receive final notification from Chrysler,"NHTSA said in a statement. In its own statement Friday, Chrysler said, "We share NHTSA's commitment to safety." NHTSA's outgoing chief, David Strickland, told The Associated Press in an interview last month that Chrysler had convinced NHTSA that the Jeeps were no more dangerous than similar vehicles sold at that time. "Those vehicles performed at a rate similar to their peers. That is the keystone analysis as to whether something poses an unreasonable risk to safety," Strickland said. Friday was Strickland's last day at NHTSA. He is joining Venable, a law firm. NHTSA began investigating the Jeeps at the request of the Center for Auto Safety, a Washington-based advocacy group. "It is tragic that NHTSA approved Chrysler's sham trailer hitch recall for Jeeps that explode in rear impacts," the Center for Auto Safety's director, Clarence Ditlow, said Friday.

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).

FCA expands Jeep Cherokee recall to 68k more vehicles

FCA is expanding its airbag software update for the 2014 and 2015 Jeep Cherokee to cover 68,593 more of the vehicles worldwide. This brings the total to 316,774 Cherokees. Of those, there are now 230,240 in the US, 28,110 in Canada, 6,367 in Mexico, and 52,057 outside of NAFTA. According to the automaker, after reviewing the potentially affected population, it discovered these additional Cherokees in need of the upgrade. The original campaign to repair these vehicles was announced in early February. Engineers found a small number of cases where dramatic changes to the angle of the vehicle that upset its balance caused the side-curtain and seat-mounted side airbags to deploy because they anticipated a rollover. This especially occurred when driving off-road. According to FCA, there're no additional reports of this happening, and the company isn't aware of any injuries or accidents. The fix is simply a software upgrade that recalibrates the airbags' deployment. Related Video: Statement: Restraint-System Software Upgrade May 12, 2015 , Auburn Hills, Mich. - FCA US LLC is expanding by an estimated 62,148 vehicles its recall of U.S.-market SUVs** to upgrade air-bag software. The action follows a routine review of the originally reported vehicle population by FCA US engineers. There have been no additional incidents and FCA US is unaware of any related injuries or accidents. The campaign will upgrade software that governs side-curtain and seat-mounted side air bags following a small number of inadvertent deployments – most of which occurred in harsh, off-road environments. They were prompted by maneuvers that dramatically changed the vehicles' angle of operation, relative to the ground, and the air-bag systems – sensing potential rollover conditions – automatically activated. The software upgrade will recalibrate the threshold for deployment and the vehicles will remain compliant with all applicable safety regulations. Affected are certain 2014 and 2015 Jeep Cherokees. The revised estimate for the U.S. totals 230,240. Revised estimates for other markets are as follows: 28,110 in Canada; 6,367 in Mexico and 52,057 outside the NAFTA region. The revised global total is 316,774 – a difference of 68,593. The Company will notify affected customers. Software will be available at that time.
