This page covers 1 recall and 151 owner complaints for the 2016 Fiat 500x.
The dominant complaint pattern for the 2016 Fiat 500X centers on the powertrain and engine. Transmission complaints are the most common, with owners frequently describing unexpected loss of drive, the vehicle slipping into neutral without input, sudden deceleration at highway speeds, and the transmission entering limp mode, conditions that often triggered a service transmission warning light. Some owners report the gear selector becoming unresponsive, leaving the vehicle stuck and unable to move. Engine-related complaints follow closely, with owners describing stalling at speed, complete loss of electrical power during a stall, and the vehicle requiring multiple restart attempts before it would run again. A recurring sub-theme in engine complaints involves the evaporative emissions system, where a failed pressure sensor triggered check engine lights and fuel gauge irregularities. Exterior lighting rounds out the top three reported systems, though at lower volume.
