Other Faults on This Variant
Exhaust Back Box Corrosion
MinorThe mild steel exhaust back box rots through exceptionally quickly, often causing the exhaust to snap and drag on the floor.
Body Control Module (BCM) / Wiring Loom Failure (Hatch Wiring)
ModerateElectrical gremlins are common on the Fiat 500. The most notorious is the wiring loom snapping where it passes from the body into the boot lid/hatch.
Air Conditioning Condenser Leak (Stone Damage)
MinorThe air conditioning condenser is mounted at the very front of the cooling pack, making it highly susceptible to stone damage from the road, leading to refrigerant loss.
