Is Fiat reliable? Quick answer
Based on 1,879 real NHTSA complaints across 5 Fiat models
Fiat reliability varies significantly by model and year. Some Fiat models have consistently low complaint rates; others show recurring transmission / drivetrain patterns across multiple generations. The brand-level reliability score is less useful than picking the specific model + year you're considering.

Fiat Reliability — Frequently Asked Questions
How many NHTSA complaints does Fiat have?
Fiat has 1,879 NHTSA consumer complaints across 5 distinct models in the VinItel database (1995–present). 5.3% of those complaints involved a crash. Source: NHTSA Office of Defects Investigation via VinItel.
Which Fiat model has the most NHTSA complaints?
By total complaint volume, the top Fiat models are: Fiat 500 (1,116 complaints), Fiat 500X (311 complaints), Fiat 500L (300 complaints). Note that higher-volume models naturally accumulate more complaints, so per-model severity depends on sales volume and crash rate. See the full sortable ranking at vinitel.com/stats/nhtsa-complaints/fiat.
What are the most common Fiat problems?
Across all Fiat models in the NHTSA database, the most-reported issue categories are: Transmission / Drivetrain (565 complaints, 1.8% crash rate); Electrical Faults (246 complaints, 2.4% crash rate); Engine Problems (216 complaints, 1.4% crash rate). Crash percentages indicate how often that component failure resulted in an accident — higher percentages are safety-critical.
Which Fiat model years should I avoid?
Fiat models with the highest severity scores include Fiat 124 Spider and Fiat 500. Specific model years to avoid depend on the model — click any Fiat model to see its year-by-year breakdown with complaint counts, crash rates, and recalls. Our AVOID label is applied when a year's normalized complaint rate exceeds 1.5× the model's median.
Which Fiat model is the most reliable?
Among Fiat models with at least 200 NHTSA complaints (enough data for a confident comparison), the lowest severity scores are: Fiat 500X (311 complaints), Fiat 500L (300 complaints), Fiat 500 (1,116 complaints). Lower complaint volume plus lower crash/fire/injury rates indicates fewer reported safety issues per vehicle on the road.
Is Fiat a reliable car brand?
NHTSA complaint data shows reliability varies significantly by model and year within every major brand — including Fiat. A brand-level reliability verdict is misleading because it averages a bad year of one model with a great year of another. VinItel's approach: pick your target Fiat model + year and view that specific page for actionable reliability data. See vinitel.com/stats/nhtsa-complaints/fiat to browse all 5 Fiat models.
Should I buy a used Fiat?
Buying used requires two checks: (1) research the specific model + year for known problems using the NHTSA data on this page, and (2) run a VIN report on the exact car to check for hidden accidents, title issues, and odometer rollbacks. VinItel offers both — reliability research is free, individual VIN reports are $4.99 (vs. Carfax $44.99). Common Fiat issues to ask about during inspection include transmission / drivetrain.
