Not owner surveys, not warranty statistics, not forum lore: what we actually found.

How long does a Infiniti last?
Across every Infiniti body style we've inspected — sedans, SUVs and anything else pooled together — the average one's condition dips below decent (a 55/100 score) around ~121k miles. It ranks Infiniti #11 of 24 brands we have enough data to rate; the longest-lasting, Tesla, holds up to ~182k. Shopping a Infiniti near that mileage? Expect more wear ahead — see which makes give the best odds at your budget.
Good cars by mileage
Good cars by age
Share of Infinitis in good shape (scoring 60+/100) by mileage and by age when we inspected them (each dot ≥5 cars; a band under 20 cars follows the nearby bands, so a run above the all-cars line stays above it, and a band of 20 or more uses the rate we measured; where a band has too few cars, the line follows the trend between the bands on either side; rolled-back odometers excluded from the mileage curve). The dashed grey curve is all cars we check.

The bottom line
Shiny paint is the norm, not proof of care, so treat it as a cue to look for structural repair. The real cost sits in the engine and the electronics: oil leaks lead, cooling problems follow, steering fluid weeps, and codes are often active or cleared. Condition tends to dip below decent around 121,000 miles, and longevity only ranks mid-pack. Scan before you talk price, check a cold engine for oil and coolant leaks, and walk if you find structural work or miles well past that point unless the discount already pays for those fixes.
