According to the Chrysler's Group official statement, a routine warranty data review prompted an investigation from which it was discovered that a PIM defect may seep coolant onto electrical components, causing a loss in power or even the short circuit of the drivetrain.
The coolant ensures the ideal temperature of the 24kWh lithium-ion battery pack powering the Italian all-electric vehicle. The power inverter module (PIM) alters the electric current from DC-to-AC and DC-to-DC to accommodate battery-powered propulsion. Up till now, Fiat USA is aware of five such incidents, that fortunately didn't end up in accidents or the injury of vehicle occupants.
2013-2014 Fiat 500e built between September 24th, 2012 and April 4th, 2014 are subjected to this latest recall. Affected customers, all of whom are in the United States, will be contacted as soon as possible by the company to be informed on the call-back operation and scheduling the repair job.
Owners who are concerned may call the Fiat Customer Assistance Center at 1-888-242-6342.
