INFINITI QX60 — what actually breaks, by engine
2015–2018 · 212 federal complaints · 1 engines
Reliability ratings usually stop at the model. But two QX60s with different engines can fail in completely different ways — and the engine is a choice you make at purchase. Here is what owners actually complained about, separated by engine.
Ownership profile
Each axis is this model's percentile within its own segment — comparing a pickup's fuel economy against a compact car's would say nothing. Built from EPA test data.
Value for money
$44,000
Capability per relative dollar, ranked against the same segment. It divides this model's average percentile across the axes above by its price relative to the segment median — so 80 means it delivers more per dollar than 80% of its class.
Price source: author's estimate, not verified against an authoritative source. Unlike every other figure on this page, the price is not drawn from NHTSA or EPA records and has not been verified against an authoritative source. Treat this one axis as indicative, not exact.
What each engine's complaints are about
Share of component mentions. One complaint can name several components, so these describe what an engine's complaints are about — they are not a failure rate.

Method, sources and limitations
How this was built
- Source: NHTSA public complaint database (api.nhtsa.gov), retrieved 2026-08-16. Every complaint carries the first 11 characters of the vehicle's VIN.
- Those partial VINs were decoded through NHTSA's vPIC service to identify the exact engine — 98.0% resolved successfully. This is how the data gets to engine level; model-level ratings cannot do this.
- Percentages are the share of component mentions, not of complaints. One complaint can name several components, so the figures describe what a given engine's complaints are about — they do not sum to a failure rate.
What this does not tell you
- This is not a reliability ranking. Complaint totals track how many were sold, not how often they fail. Nobody publishes per-engine sales volume, so comparing totals between engines would be misleading. Read each engine's own breakdown; don't race them against each other.
- Engines with fewer than 50 complaints are omitted — too small to say anything honest about.
- Complaints are self-reported by owners. They skew toward problems that are alarming or expensive, and toward vehicles under active recall attention.
