Fiat 500 312 (thermique) (2007 – 2023)

Reliability score : 7.8/10

The Fiat 500 (Generation 312) is an icon of modern automotive design. Launched in 2007, this neo-retro city car saved Fiat thanks to its timeless design and immense commercial success. Based on the Fiat Panda II platform, it received a major facelift in 2015 (Phase 2) improving sound insulation, the infotainment system (Uconnect), and the light signature. Although its overall design is old, it remains a benchmark in urban environments. Its reliability depends drastically on the engine and gearbox chosen. The internal combustion versions coexisted with the new electric 500 (Gen 332) until their gradual withdrawal.

✅ Strengths

Timeless design and enduring appeal
Legendary reliability of the 1.2 FIRE 69 hp engine
Very low maintenance and insurance costs
Exceptional maneuverability in the city (City mode for steering)
Availability and price of spare parts
Very low depreciation (excellent resale value on the used market)

⚠️ Weaknesses

Catastrophic Dualogic automated manual gearbox (slow, jerky, actuator failures)
Imperfect driving position (steering wheel not adjustable for reach)
Rear tailgate wiring harness that breaks over time
Very fragile 'Blue&Me' Bluetooth/USB module (before 2015) (causes the odometer to flash)
Rapid wear of front suspension components (wishbones, strut mounts, silentblocks)
Interior door handles whose hinge breaks easily

🎯 Verdict

The Fiat 500 is an 'emotional purchase' that can prove very rational if you choose the right version. The verdict is clear: absolutely prioritize the 1.2 FIRE 69 hp engine or the recent 1.0 FireFly MHEV, always with a manual gearbox. In this configuration, the 500 is one of the most reliable and economical city cars on the market. However, you must avoid the Dualogic automated manual gearbox, avoid the 0.9 TwinAir engine (too temperamental and expensive to maintain), and banish the 1.3 MultiJet diesel if you drive in the city. Minor finish defects (handles, trunk wiring harness) are real but inexpensive to repair compared to mechanical failures in other competing models.
