2012 Fiat 500 problems

• 1.3 Multijet II 16v Euro 5 (75-95 hp, 2009-2015)

  75–95 hp · Z13DTH, 199B1.000

  It improves consumption and noise compared with the first generation, but shares the same chain and tensioner design, with documented cases of stretching. Ask for the maintenance history and watch for oil dilution if the car is used mostly in town.^[3][4]

Faults that affect 2012 cars

• Critical severityFrequency: CommonTimingTiming chain stretch and tensioner failureYes: the timing chain's hydraulic tensioner can lose pressure and let the chain slacken; if it skips teeth or breaks, it can destroy the engine. It is a documented problem on Fiat, Opel, Suzuki and Ford cars with this engine, mainly linked to long oil change intervals.Repair (garage): €350–€550Appears at around 70,000 km
• High severityFrequency: CommonEmissions controlIncomplete particulate filter regenerations and oil dilutionIn heavy urban use, with short journeys that do not let the particulate filter regeneration finish, unburnt diesel passes into the sump and dilutes the oil; the level can rise on the dipstick and the oil loses its ability to lubricate. Repeated many times, it speeds up engine wear.
• High severityFrequency: OccasionalTurboSeized variable-geometry turboOn versions with a variable-geometry turbo, the vanes can seize through soot build-up, especially on cars used in town for short journeys. The engine loses power gradually and may give off black smoke when accelerating.Repair (garage): €450–€700
• High severityFrequency: OccasionalInjectionInjector and high-pressure pump wear from contaminated fuelThe Bosch injectors and the high-pressure pump of the common rail system are sensitive to poor-quality fuel or fuel with condensed water. With contaminated diesel they can generate metal shavings that damage first the pump and then the injectors themselves.Repair (garage): €600–€1,200
• Medium severityFrequency: CommonEmissions controlEGR valve blocked by sootThe 1.3 Multijet's EGR valve easily accumulates soot on short urban journeys, causing an unstable idle, loss of power and the engine warning light. It is one of the most cited problems among owners of this engine.Repair (garage): €130–€400

• 0.9 TwinAir 78-105 hp (2010-2020)

  78–105 hp

  No source consulted documents a systemic fault or one affecting most units; the turbo, MultiAir unit, clutch/flywheel and oil consumption cases covered on this page always appear in a minority of the reports analysed. It is worth checking the service history and test-driving the car from cold before buying.^[6][7][8][9]

Faults that affect 2012 cars

• High severityFrequency: OccasionalTurboEarly turbocharger failure (0.9 TwinAir)The 0.9 TwinAir's turbo can fail, in some cases at low mileage: there is one documented case replaced under warranty at 13,000 km in the Fiat 500 and another, a turbo hose, at 51,000 km in the Fiat Panda III. A specialist German source describes it as an infrequent problem.
• Medium severityFrequency: OccasionalIntakeMultiAir/UniAir hydraulic unit failure (0.9 TwinAir)The 0.9 TwinAir's MultiAir (or UniAir) hydraulic unit, which controls the intake valves with oil pressure, can fail and cause loss of power or rough running; there is one documented case replaced at 30,000 km in the Fiat 500. It is a minority problem, not a systemic fault.
• Medium severityFrequency: OccasionalClutchClutch and flywheel wear (0.9 TwinAir)The 0.9 TwinAir's clutch and flywheel can wear sooner than expected: there are documented cases in the Fiat 500 (27,000 km), the Fiat Panda III (73,000 km) and the Fiat Punto, where a faulty flywheel went on to damage the clutch. The more uneven running of a two-cylinder puts more strain on these parts.
• Low severityFrequency: OccasionalLubricationOil consumption (0.9 TwinAir)The 0.9 TwinAir can use more oil than normal: several reports for the Fiat Panda III describe having to top up almost a litre a month. Fiches-auto.fr describes it as a problematic tendency of this engine in that model; no technical origin has been identified in the sources consulted.
• Low severityFrequency: OccasionalElectronicsStart&Stop system faultsThe Start&Stop system can stop working or become unreliable: there are cases in the Fiat Panda III and the Fiat Punto (unusable from 40,000 km) with the 0.9 TwinAir, and in the Jeep Renegade with the 1.0 GSE T3 Turbo. It does not affect normal driving, but the electrical system is worth checking.

• Dualogic 5-speed (2003-present)

  · C510

  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.^[6][7]

Faults that affect 2012 cars

• 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.
• 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

• 1.2 8v VVT 69 hp (2007-2020)

  69 hp

  This is the variant with the most reliability data available. In the Fiat Panda III (50 reviews) barely 1 engine-related case is documented and none involving the timing belt; in the Fiat 500 (147 reviews) the most repeated issues are the ignition coil and oil consumption, always in a minority of cases. Gebrauchtwagenberater.de describes the engine as robust in both the Fiat 500 and the Fiat Panda III.^[6][7][8][9]

Faults that affect 2012 cars

• Medium severityFrequency: OccasionalElectronicsSensor failures: lambda sensor and crankshaft position sensor (TDC)The 1.2 8v Fire can suffer sensor faults: the lambda sensor (warning light, rough running) and, in the Fiat Punto, the crankshaft position sensor (TDC sensor), linked to misfires. These are minority issues, but they recur across several models with this engine.
• Low severityFrequency: OccasionalLubricationOil consumption or leak, in one case from the rocker cover gasketThe 1.2 8v Fire can start to use or lose oil after a certain mileage; the only case with an identified origin points to the rocker cover gasket. It is the issue that recurs most for this engine, always in a minority of cases and without damaging the block.
• Low severityFrequency: OccasionalIgnitionFaulty ignition coil (misfire, engine warning light)The 1.2 8v Fire's ignition coil can fail and switch on the engine warning light, with rough running; there is one documented case replaced at 40,000 km in the Fiat 500. It is one of the issues that recurs most in the sources consulted for this engine, though always in a minority of cases.
• Low severityFrequency: RareTimingTiming belt: preventive replacement, no documented breakage patternThe 1.2 8v Fire has a timing belt, which must be replaced preventively according to the interval set by the manufacturer of the specific car. The reliability sources consulted document no case of premature breakage for this engine: it is scheduled maintenance, not a recurring fault.

• Critical severityFrequency: RareSuspensionFront wheel bearing that could come loose (2024 campaign)In 2024 Fiat opened a recall campaign (code 6687) to check the bearing of a front wheel that, on certain 500 units, could come loose. The source consulted does not specify the production period covered or the number of cars affected.
• Critical severityFrequency: RareElectrical systemRisk of the auxiliary battery overheating on mild-hybrid versions (October 2022 campaign)In October 2022 Fiat opened a safety campaign for the mild-hybrid versions of the 500 over a hybrid system deficiency with a risk of the auxiliary battery overheating. The source consulted does not detail the production period or the number of units affected.
• Critical severityFrequency: RareSteeringSteering mount made of unsuitable material that can make the car harder to control (June 2021 campaign)In June 2021 Fiat opened a campaign because the steering mount on some 500 units was made of unsuitable material that could make the vehicle harder to control. The source consulted does not detail the production period or the number of cars affected.
• Critical severityFrequency: RareGearbox and clutchRight-hand front driveshaft (half-shaft) that can give way on the move (July 2019 campaign, ref. 6228)In July 2019 Fiat registered campaign 6228 because the right-hand front driveshaft (half-shaft) on some 500 units could develop problems and give way while the car was moving. The source consulted does not detail the production period or the number of units affected.
• High severityFrequency: RareGearbox and clutchPremature clutch wear and jumps into neutral on the Dualogic gearboxTestimonies from Fiat 500 owners with the Dualogic robotised gearbox describe a clutch that wears out sooner than expected (cases between 27,000 and 55,000 km) and involuntary jumps into neutral or refused gear changes in automatic mode; there is no official campaign or specialist press to confirm it.Appears at around 27,000 km
