Infiniti Reliability — Frequently Asked Questions
How many NHTSA complaints does Infiniti have?
Infiniti has 9,623 NHTSA consumer complaints across 30 distinct models in the VinItel database (1995–present). 6.4% of those complaints involved a crash, and 38 involved a fatality. Source: NHTSA Office of Defects Investigation via VinItel.
Which Infiniti model has the most NHTSA complaints?
By total complaint volume, the top Infiniti models are: Infiniti G35 (1,854 complaints), Infiniti Qx60 (793 complaints), Infiniti G37 (720 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/infiniti.
What are the most common Infiniti problems?
Across all Infiniti models in the NHTSA database, the most-reported issue categories are: Airbags (1,125 complaints, 10.2% crash rate); Electrical Faults (951 complaints, 2.3% crash rate); Engine Problems (856 complaints, 2.1% crash rate). Crash percentages indicate how often that component failure resulted in an accident — higher percentages are safety-critical.
Which Infiniti model years should I avoid?
Infiniti models with the highest severity scores include Infiniti I35 and Infiniti Q45. Specific model years to avoid depend on the model — click any Infiniti 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 Infiniti model is the most reliable?
Among Infiniti models with at least 200 NHTSA complaints (enough data for a confident comparison), the lowest severity scores are: Infiniti Qx50 (354 complaints), Infiniti Qx60 (793 complaints), Infiniti Q50 (704 complaints). Lower complaint volume plus lower crash/fire/injury rates indicates fewer reported safety issues per vehicle on the road.
Is Infiniti a reliable car brand?
NHTSA complaint data shows reliability varies significantly by model and year within every major brand — including Infiniti. 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 Infiniti model + year and view that specific page for actionable reliability data. See vinitel.com/stats/nhtsa-complaints/infiniti to browse all 30 Infiniti models.
Should I buy a used Infiniti?
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 Infiniti issues to ask about during inspection include airbags.
