With cautionThe chain eliminates the belt problem, but you need to confirm that the 2025 recall for a possible petrol leak has been done and, on units built up to February 2024, the correction of the camshaft sprocket bolts.[3][4]
Faults that affect the 600
Only those that affect the versions and years that this car used. The 1.2 PureTech has 7 documented faults in total.
- Critical severityFrequency: RareFuelPossible petrol leak in the high-pressure circuit (chain-driven generation)In 2025 Stellantis recalled the new-generation 1.2 turbos (chain-driven, 100 and 136 hp, hybrids included) built from 2023 to 2025: a joint on the high-pressure pipe could leak petrol, with a risk of fire. It is fixed with a free re-tightening taking under 30 minutes.Repair: €0
- High severityFrequency: RareTimingTiming misalignment from the camshaft sprocket bolts (chain-driven generation)On the third-generation 1.2 (chain-driven) built up to 17 February 2024, the camshaft sprocket bolts could be incorrectly fitted and throw the timing out: engine warning light, loss of power and, in the worst case, contact between pistons and valves.

Faults of the Fiat 600 outside the engine
Suspension, brakes, electronics and the rest of the car: they occur with any engine.
- High severityFrequency: OccasionalGearbox and clutchJerking, lock-ups and risk of early failure in the e-DCS6 hybrid gearboxYes: fiches-auto.fr documents that the e-DCS6 hybrid dual-clutch gearbox in the Fiat 600 can produce jerking and lock-ups, with cases of early failure, and several owners have reported transmission faults; the source itself notes that this recently introduced gearbox 'has yet to prove its reliability'.
- Critical severityFrequency: RareElectrical systemFire risk from water ingress into the 48 V belt-starter generator protection (built 2023-2025)Yes: a recall covers cars built between 28 July 2023 and 19 December 2025 in which insufficient clearance between the petrol particulate filter pipe and the protective cap of the 48 V starter-generator allows water in and can cause an electrical arc and a fire.
- Critical severityFrequency: RareSteeringPower steering motor with a crack that can lock the steering (built April-May 2024)A European campaign covers the Fiat 600 and 600e built in April-May 2024, in which a crack in the electric motor of the steering rack can release plastic pieces from the worm wheel and lock the steering.
- Medium severityFrequency: OccasionalElectronics and infotainmentInfotainment screen and driver-assistance sensor faults (pedestrian detection, camera, rear radar)Yes: two pages on fiches-auto.fr document central screen freezes, pedestrian detection warnings with no apparent cause, warning lights that come on without a clear explanation, and slow responses or loss of the camera and rear parking radar.
- Medium severityFrequency: RareElectronics and infotainmentRadio software that allows emergency braking and lane keeping to be switched off together (built March-April 2024)CarWiki lists a campaign under which, on Fiat 600s built from late March to early April 2024, a radio software fault allowed the emergency braking and lane keeping assistants to be switched off together.
