Fiat 500 312 (thermique) (2007 – 2023)

Reliability score : 7.4/10

The Fiat 500 (generation 312) is an icon of modern automotive design. Launched in 2007, it resurrected the 'Cinquecento' myth with phenomenal commercial success, based on the Fiat Panda II platform. It received a major facelift (Phase 2) in 2015. Although its primary purpose is urban, Fiat made the choice (very popular at the time in Europe) to equip it with the small 1.3 MultiJet diesel engine. While this unit is intrinsically robust and very economical on the road, its association with purely urban use has generated numerous reliability problems (DPF, EGR valve, timing chain). This report focuses on the diesel versions while providing an exhaustive overview of other powertrains to help you make the right choice.

✅ Strengths

Timeless design and unparalleled charm
1.3 MultiJet engine, very torquey and economical on open roads
1.2 Fire petrol engine with exemplary reliability
Ideal size for parking (3.57 m)
Very low cost of spare parts (excluding TwinAir and Diesel DPF)

⚠️ Weaknesses

Diesel engine (1.3 MJT) catastrophic if used only in the city (DPF, EGR, Chain)
Imperfect driving position (steering wheel not depth-adjustable)
Very limited rear passenger space and boot volume (185 liters)
Dualogic automated gearbox slow, prone to jerks and actuator failures
Rapid wear of front wishbone bushings and shock absorber mounts

🎯 Verdict

The Fiat 500 is an emotional purchase that can prove very rational, provided you choose the right engine. Regarding the 1.3 MultiJet Diesel: it's an excellent engine for a Punto or a Tipo that drives a lot, but it's nonsensical in a 500 intended for the city. If you buy a used 1.3 MJT, make sure the previous owner drove on the open road and absolutely check the condition of the timing chain. For 90% of Fiat 500 buyers, the modest but indestructible 1.2 Fire 69 hp (or the recent 1.0 hybrid) is the absolute preferred choice. Avoid TwinAir versions and the Dualogic automated gearbox.
