Jeep Renegade sales being held due to powertrain issue [UPDATE]

UPDATE: An unnamed FCA US source has clarified to Automotive News that while there is a software issue, it does not concern the transmission. The Jeep Renegade appears to be facing early software problems that are similar to the ones at the introduction of the Cherokee a few years ago. The issue is keeping the brand's latest compact crossover away from dealers until the situation can be resolved. The fault reportedly deals with the software controlling the Renegade's nine-speed automatic transmission. FCA CEO Sergio Marchionne briefly talked about what was happening in an interview with Automotive News. "I'm having a very bad engineering day," he said. "It's a combination of attributes of that vehicle that is making my life horrible." The company boss predicted at the longest it could take until mid-June to fix things. Through April, Jeep has sold 5,157 Renegades, including 4,214 of them in that month alone. Autoblog reached out to an FCA US spokesperson to learn more about the software problem, but the company had no comment. Getting the software right to control the nine-speed automatic plagued development of the Cherokee. The issues delayed the model's launch in 2013, and the company was still releasing improvements for some vehicles this year.

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).

2014 Jeep Grand Cherokee probed by NHTSA for brake problems

Remember how Toyota got in all kinds of trouble over unintended acceleration? Well, the National Highway Traffic Safety Administration is investigating Jeep over unintended braking. NHTSA has announced a probe of 20,000 Grand Cherokee SUVs from model year 2014. Nine complaints have been received, with owners alleging that their Jeeps have issued brake warnings or gone ahead and applied the brakes when no threat was presented. Each complaint alleges that the vehicles have exhibited this behavior repeatedly, leading to a "sudden reduction in vehicle speed in traffic." So basically, a system designed to prevent accidents could actually increase the odds of a collision happening. Speaking to the Associated Press, Jeep spokesperson Eric Mayne said owners whose vehicles are exhibiting this behavior should report to dealers, while adding that the automatic braking/adaptive cruise control systems can be deactivated.

Date Investigation Opened: JUN 01, 2015 Date Investigation Closed: Open NHTSA Action Number: PE15021 Component(s): FORWARD COLLISION AVOIDANCE Manufacturer: Chrysler (FCA US LLC) SUMMARY: The Office of Defects Investigation (ODI) has received nine complaints alleging inappropriate activations of the autonomous braking system in model year (MY) 2014 Jeep Grand Cherokee vehicles. All nine reports alleged unexpected braking incidents preceded by collision imminent brake warnings and resulting in sudden reduction in vehicle speed in traffic. Two complaints reported autonomous braking incidents with no objects on the road resulting in rapid increase in brake force and anti-lock braking system (ABS) activations. The complaints alleged experiencing multiple events at different locations and road conditions. A Preliminary Evaluation has been opened to assess the frequency, scope and consequences of the alleged defect.
