In August 2013 Chrysler issued a recall to replace bolts that secure the Fiat 500e half-drive-shafts. The recall was not related to the 500e's electric powertrain and affected 291 model year 2013 Fiat 500e cars, including vehicles at dealers' lots. When an investigation was launched after a customer's 500e exhibited power loss, engineers discovered two assembly steps that had not been properly completed, thereby creating a condition that could lead to half-shaft separation. Fiat 500e owners affected by the recall were to receive free rental vehicles while their cars were repaired at no charge.
