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.
