NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.

FCA and ZF issue recall on nine-speed automatic transmission

After years of complaints, German transmission manufacturer ZF is finally issuing a recall of its much maligned 9HP nine-speed automatic transmission. Although it has been criticized for a number of issues, ZF is issuing the recall to address the possibility of the transmission unexpectedly shifting into neutral. The issue covers 505,000 vehicles in the United States alone. This issue is related to an improper crimp on the transmission wiring harness. Rather than a physical fix, ZF is issuing a software update to remedy the problem. The company doesn't recommend dealers attempt to fix the crimp. Although the transmission can be found in a number of models by various manufacturers, currently only those from FCA are being recalled. This is the second recall in less than a year related to a ZF transmission shifting into neutral. FCA recently recalled more than a million vehicles worldwide because of a poorly designed shifter for ZF's 8HP eight-speed automatic. That issue may have resulted in the death of actor Anton Yelchin in June. Although there are no deaths related to this new recall, NHTSA reports that the issue has resulted in at least 10 injuries. Issues with the transmission have been known for years. A number of software updates have attempted to address various problems, making us wonder if there could be a fundamental hardware issue as the complaints span across a number of automakers. Vehicles equipped with the 9HP include 2014 and newer versions of the V6 Acura TLX, Chrysler 200, Fiat 500X, upper-level Honda Pilots, Jeep Cherokee and Renegade, Land Rover Discovery Sport and Range Rover Evoque, and Ram ProMaster City. Only FCA is issuing a recall and only on 2014 and 2015 models. Related Video: News Source: NHTSA Recalls Chrysler Fiat Jeep Safety FCA nine-speed transmission

Jeep Grand Cherokee SRT gets power increase, minor tweaks for 2015

As a brand within Fiat Chrysler Automobiles, SRT may have an uncertain future, but it's pumping out some seriously mean machines anyway. The supercharged Hellcat V8 may be gobbling up most of the headlines with its 707 horsepower, but even the Grand Cherokee SRT is getting some small updates for the 2015 model year.
Most importantly for many enthusiasts, the Grand Cherokee SRT is getting a slight power bump. Don't expect the 700+ hp from the Hellcat, but this SUV sees a modest 5-hp and 5-pound-feet of torque improvement to bring output to 475 hp and 470 lb-ft for its 6.4-liter V8 with an eight-speed automatic. The minor change doesn't change the sprint to 60 miles per hour, clocking in at the same 4.8 seconds, or the tow rating at 7,200 pounds. Still, more grunt is never a bad idea.
Another new addition is the Active Noise Canceling system as a standard feature for this powerful SUV. It adds four microphones around the vehicle and uses the stereo system to nullify extraneous sound. However, Jeep claims that the meaty exhaust note from the V8 still gets through into the cabin for driver enjoyment.
