Fiat 500e Update and Recall

Fiat 500e Lined Up

Fiat has announced the Fiat 500e all electric vehicle will receive a hardware and software update. The first is a voluntary recall to update the Power Inverter Module. The second involves updating the software in multiple control modules for enhanced operation.

Voluntary Recall
During the course of routine warranty data reviews, Chrysler Group engineers discovered an issue with the Power Inverter Module (PIM) in the Fiat 500e that may cause a loss in power while driving. It is possible the PIM may over time begin seeping coolant and this leak could cause a short circuit if the coolant gets into electrical components. This could result in a loss of power. Chrysler is aware of five such incidents happening, however, they are unaware of any related accidents or injuries.

Fiat 500e PIM

The PIM function is to convert the direct current (DC) of the high voltage battery into alternating current (AC) necessary to power the electric motor. The PIM is located in the under-hood area above the eMotor and under the On Board Charging Module (OBCM). Coolant is circulated through the PIM to remove the heat that it produces.

The PIM also acts as a replacement for the alternator used in gasoline engines, charging the 12 volt battery and providing current up to 170 amps to support the vehicle low voltage electrical accessories. These include:
• The Electric A/C Compressor (EAC)
• The Air Electric Heater (AEH)
• Lighting
• Infotainment

Affected Cars
Fiat Chrysler Automobiles is replacing PIMs in 2013-14 Fiat 500e vehicles assembled between Sept. 24, 2012 and April 4, 2014. This amounts to approximately 4,141 cars. Owners of the Fiat 500e will be contacted directly and advised when they may schedule service. Associated costs will be borne by the Company.

Customers who are concerned may call the Fiat Customer Assistance Center at 1-888-242-6342.
