2015 Jeep Cherokee finds a bit more fuel mileage thanks to stop/start and aero tweaks

Just a year after it burst onto the scene, Jeep has already made a pretty substantial addition to its V6-powered Cherokee, which has proven to be an extremely popular seller so far for the brand, adding a new stop-start system for the midsize, off-road-ready CUV.
The addition of stop-start included a few aerodynamic tweaks to the Cherokee's polarizing body, resulting in a wallet-pleasing increase in fuel economy. According to the EPA, the front-drive, V6-powered Jeep will now return 21 miles per gallon in the city and 29 mpg on the highway, up from 19 city and 28 highway. Four-wheel-drive, V6-powered Cherokees, meanwhile, will now return 20 mpg in the city and 28 mpg on the highway, up from 19 mpg in the city and 27 mpg.
With 271 horsepower, 239 pound-feet of torque and these newly enhanced figures, it's refreshing to see a larger, naturally aspirated engine that is still able to take the fight to today's crop of small-displacement, turbocharged four-cylinders.

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.

Jeep Renegade and Fiat 500X finally on the way to dealers

After a brief pause, the Jeep Renegade and Fiat 500X are on their way to dealers again. While initially reported as a software bug, the issue had nothing to do with the models themselves. According to a statement from FCA US to Autoblog, the "vehicles were built with an atypical Vehicle Identification Number that may not be recognized as valid by some computer systems." That problem has now been fixed. FCA US held the compact crossovers back from dealers until the company could rectify the bug. If the CUVs had been delivered, there would have been difficulty registering the vehicles, according to Automotive News. Before discovering the situation, about 20 of these Renegades were sold to customers. FCA CEO Sergio Marchionne originally discussed the predicament in late May. "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." While the boss predicted the problem would be fixed as late as mid-June, the company apparently got things working much quicker than that.

This VIN issue has been resolved. FCA US has been working with governmental agencies, insurers and financial institutions with whom customers may interact to ensure successful registration, financing and insurance coverage. Renegade and 500X vehicles are being shipped and are in stock at dealerships for purchase. The VIN issue is entirely separate from the operation of the vehicle.
