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 ~184k. 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
These cars run from excellent to poor in almost equal shares, so the badge is not a filter, and fresh paint is more often a cover than a plus. Faults cluster under the hood: oil leaks, cooling trouble, and hydraulic steering seepage, with active codes and worn tires right behind. Cold-start it, watch the pavement, scan it, and check the rubber before you fall for the cabin. They tend to slip below decent around 121,000 miles, so stay under that. Original panels and a dry engine bay justify the money; repaint plus wet leaks means negotiate hard or walk.
