5,600 Fiat 500e EVs recalled for buggy software

Fiat will be recalling some 5,600 of its all-electric 500e hatchbacks, all of which hail from model years 2013, 2014 and 2015. Weirdly, this recall is being caused by a March 2015 software update. According to The Detroit News, last month's update addressed the software in the Electric Vehicle Control Unit and Battery Pack Control Module "to implement improvements in charging system robustness, diagnostic capability and range estimation over life. In addition to the primary reasons for the software update, Limp Home Mode was included as part of battery pack software continuous improvement," FCA explained. "It was because of this software update that the software incompatibility occurred where the EVCU did not recognize the Limp Home Mode." Should your car go into limp mode, "incompatible software between Electric Vehicle Control Unit (EVCU) and Battery Pack Control Module (BPCM) may cause the electric propulsion system to fully shut down," according to the National Highway Traffic Safety Administration bulletin. So yes, the March software update can cause your EV to stall. Vehicles built between March 27, 2012 and November 1, 2014, which sounds like basically all 500es, are affected by the recall. Chrysler will begin notifying owners with recall operations to begin in the middle of next month. Scroll down for the official NHTSA bulletin.

If the vehicle goes in to limp home mode, incompatible software between Electric Vehicle Control Unit (EVCU) and Battery Pack Control Module (BPCM) may cause the electric propulsion system to fully shut down. CONSEQUENCE: An electric propulsion system shut down will cause a stall-like condition, increasing the risk of a crash. REMEDY: Chrysler will notify owners, and dealers will update the vehicle software to ensure compatability between components, free of charge. The recall is expected to begin May 15, 2015. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is R15. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

Marchionne offers belated apology for 'wop engine' comment

Automotive News reports Fiat-Chrysler CEO Sergio Marchionne has issued a written apology for his comments regarding his decision to stick with an Italian engine for the upcoming Alfa Romeo 4C. As you may recall, back in January, Marchionne was quoted as saying, "I cannot come up with a schlock product, I just won't. I won't put an American engine into that car. With all due respect to my American friends, it has to be a wop engine." The CEO penned an apology to the Italian American ONE VOICE Coalition for using the racial epithet, saying that he made the comment in jest. Marchionne also said he realizes his remarks were unacceptable.
ONE VOICE, an organization aimed at fighting discrimination and stereotyping of Italian Americans, thanked Marchionne, Chrysler and Fiat for the apology. Marchionne is an Italian-born Canadian citizen, and he's gotten in trouble for other comments in the past. In 2011, he called high interest rates Chrysler was paying to the Canadian government "shyster rates." He apologized a day later.
