Fiat Cronos problems (2018–today)

We have documented 1 engine and 1 gearbox for the Fiat Cronos; the Dualogic gearbox has high or critical severity faults. None has a «Buy» verdict; the safest option is the 0.9 TwinAir and 1.0/1.3 FireFly, with a «With caution» verdict.[1][2]

Outside the engine: Outside the engine, the Cronos (a saloon derived from the Argo, built in Córdoba, Argentina) has accumulated four safety campaigns in Brazil, all resolved at dealerships: the electric steering shaft (2018), the GSR automated gearbox sensor (2018), the handbrake lever (2024) and the engine control unit (2025).[3][4][5][6]

Fiat Cronos rating: acceptable reliability

Calculated using only 6 documented faults and their sources: the most serious and frequent faults weigh more. Limited evidence: it is based on few sources or few documented faults, so it is not included in the rankings. Having few documented faults does not mean it is reliable: it may simply be little studied. One of this car's engines has no documented faults in the versions it uses, but there aren't enough sources to call it reliable either, so it doesn't count towards the engine score.

Documented engines, from highest to lowest risk

The first label is the most serious fault affecting that engine in this car; the second, our verdict for the versions it is fitted to. Each engine's risk index is calculated only from the faults that affect this car (how we calculate it). We only show engines we have documented with sources: if yours does not appear, we have not analysed it yet. View all engines

    With caution

    There is no systemic fault acknowledged by the manufacturer, but owner testimonies repeatedly document jerking and an interruption of drive on every gearchange (inherent to the design of a single clutch), as well as minority cases of clutches worn out early and of actuator or hydraulic pressure faults that make the gearbox drop into neutral on its own while driving; the car should be thoroughly test-driven, weighing whether the driving comfort, very different from a conventional automatic, is worth its low cost.[10][11]

Faults that affect the Cronos

  1. High severityFrequency: OccasionalElectronicsActuator or hydraulic pressure fault: the gearbox drops into neutral on its own or refuses gearsYes: when the actuator, the position sensor or the electrohydraulic control pressure stop validating the engaged gear, the Dualogic can drop into neutral on its own while driving or refuse to engage gears. Several cases are documented, some described as very dangerous, on a bend or when leaving a motorway.
  2. Medium severityFrequency: OccasionalClutchPremature wear or breakage of the Dualogic clutchThe Dualogic clutch can wear out or break sooner than expected: there are documented cases of a failed clutch ("HS") at 27,000 km on a Fiat 500 0.9 TwinAir and of breakage at 35,000 km on a 1.2, far below the usual life of a clutch.Appears at around 27,000 km

Verdict for the versions it uses

  • A Fiat campaign from December 2022 replaced the fuel supply pipe, which can degrade especially with ethanol, on 143,474 cars from 2022 and 2023, including the Argo, Cronos and Mobi. The sources do not name the engine, but these cars use these versions, so it is worth checking with the chassis number that the replacement was carried out. We found no other engine-specific faults, but also no reliability analyses.[1][2]

Among the 1 engine and 1 gearbox we have documented, none has a «Buy» verdict; the safest option is the 0.9 TwinAir and 1.0/1.3 FireFly, with a «With caution» verdict. A Fiat campaign from December 2022 replaced the fuel supply pipe, which can degrade especially with ethanol, on 143,474 cars from 2022 and 2023, including the Argo, Cronos and Mobi. The sources do not name the engine, but these cars use these versions, so it is worth checking with the chassis number that the replacement was carried out. We found no other engine-specific faults, but also no reliability analyses.[1][2]

What problems does the Fiat Cronos have apart from the engine?

Outside the engine, the Cronos (a saloon derived from the Argo, built in Córdoba, Argentina) has accumulated four safety campaigns in Brazil, all resolved at dealerships: the electric steering shaft (2018), the GSR automated gearbox sensor (2018), the handbrake lever (2024) and the engine control unit (2025). The most important documented faults are: intermediate shaft of the electric steering column with a faulty weld (2018 campaign) (steering, critical severity), handbrake lever that may fail to hold the car (2024 campaign) (brakes, high severity), GSR automated gearbox that can drop into neutral because of the gear selection sensor (gearbox and clutch, high severity) and water ingress into the engine control unit that can switch off the car while driving (2025 campaign) (electronics and infotainment, high severity).[3][4][5][6]

What faults does the Fiat Cronos have?

The most important by severity and frequency, on the engines we have documented, are: actuator or hydraulic pressure fault: the gearbox drops into neutral on its own or refuses gears (Dualogic, high severity) and premature wear or breakage of the Dualogic clutch (Dualogic, medium severity).

What is the best year to buy a Fiat Cronos?

According to our rating by year, the best are 2026, 2024, 2023 and 1 other years with the same rating (10.0/10); the worst rated is 2018 (5.5/10). Each year's rating counts only the engines sold that year and the faults that affect those units: open each year to see what changes.

Does the Fiat Cronos have recalls?

Yes: we have documented 4 campaigns for the Fiat Cronos, such as stellantis campaign of May 2025: water ingress into the engine control unit (2025). Check with your VIN at the official service centre whether yours has been done.[6]
