5,600 Fiat 500e EVs recalled for buggy software
Tue, Apr 14 2015
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.
