Before you buy a used Fiat 500X.
Taken only from Testigo's sourced sheets. Use it to question the seller and on the test drive: it does not confirm that any particular car is affected.

The essentials.
- 3 documented, sourced faults across its 3 engines.
- 2 of them depend on the equipment or the production date: ask what this car has.
- 1 official recall on record: ask for the chassis number (VIN) and confirm it has been done.
- According to the data we have, the engines with the fewest documented faults are: 1.0 / 1.3 FireFly (Petrol), 1.6 / 2.0 Multijet (Diesel).
Typical faults by engine
The period and mileage are those mentioned by each sheet's sources. They are not a maintenance interval and do not predict that any particular car will fail.

We have no faults specific to this engine, only those common to every version.
Which engine has the fewest documented faults?
| Engine | Documented faults | Recalls |
|---|---|---|
| 1.4 MultiAirPetrol | 32 with conditions | 0 |
| 1.0 / 1.3 FireFlyPetrolFewest documented | 22 with conditions | 1 |
| 1.6 / 2.0 MultijetDieselFewest documented | 22 with conditions | 1 |
According to the data we have, the engines with the fewest documented faults are: 1.0 / 1.3 FireFly (Petrol), 1.6 / 2.0 Multijet (Diesel).
By fuel type, the one with the fewest documented faults is: Diesel.
We only count the sourced sheets we have. An engine with fewer is not guaranteed to be more reliable: it may have been studied less or sold in smaller numbers.
Official recalls: ask before you pay
A recall existing does not mean this car is affected or that it is still outstanding: it depends on the chassis number, the market and the production date.
- Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
- Ask an official Fiat dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
- Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.

Valvetrain (MultiAir actuator)
Look out for: Hard or rough cold starts, hesitation, stalling and an engine light with P1523 (low oil pressure in the MultiAir system).
Ask them to check: Change the oil and filter with the correct specification, inspect the MultiAir mesh filter and measure oil pressure before replacing the actuator.
Exhaust and emissions
Look out for: Below freezing the starter turns but the engine does not start; on days without frost it starts fine. More likely after short trips.
Ask them to check: Ask the garage about bulletin 09-004-20 and whether the silencer already has the drain hole; until then, avoid leaving the car outside in frost right after a very short trip.
Known weak points
Look out for: A turbo that often fails on the 1.4 MultiAir; oil dilution and carbon build-up on the direct-injection petrols, even at low mileage; on the Multijets, particulate filter, dual-mass flywheel, turbo, EGR and injectors at high mileage; failing tail lights, electronic faults, squealing brakes and poor build quality in early years.
Ask them to check: Check the campaigns by VIN; on the MultiAir, listen to the turbo; check the tail lights and electronics.
