Chrysler axes old V6s, goes all-Pentastar

Old technology has a way of lingering on, particularly at Chrysler headquarters in Auburn Hills. So while the Pentastar V6 has replaced the older engine architecture in just about every application, it still soldiered on in some export markets. But the introduction of a new 3.0-liter Pentastar V6, produced in Michigan and meant only for the Chinese market, has put the final nail in the old engine's coffin.
Fitted into the 2014 Jeep Grand Cherokee and Jeep Wrangler just introduced to China at the Chengdu Motor Show, the downsized six uses the same architecture as the larger 3.6-liter Pentastar V6. But because of its 2,997cc capacity, it can be exported to China without the increased duty the 3.6-liter or even 3.2-liter Pentastar engines would incur. The 3.0-liter V6 develops 230 horsepower at 6,350 rpm and 210 pound-feet at 4,400 rpm.
Admittedly, it's unlikely, but even though the engine was said to be created solely to undercut tax thresholds in China and Europe, the 3.0-liter Pentastar has recently surfaced in rumors of an application here: as the boosted heart of a potential Cherokee SRT with anywhere from 375 to 410 hp.

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.

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.
