The Infiniti FX35 draws 2.13 complaints per production run against 3.73 for the average car — better than typical. The worst model year is 2003 at 2.27 complaints per run; the best is 2012 at 1.75 — a 1.3-fold gap between two cars wearing the same badge. Failures cluster at 8 years, so only 15.8% of them fall inside the 4-year basic warranty.
Infiniti FX35 years to avoid — and the best ones
The Infiniti FX35 year to avoid is 2003, at 2.27 complaints per production run. The best is 2012 at 1.75 — 1.3 times cleaner for a car wearing the same badge. Both figures are rates, not totals: a raw count only tells you which year sold well, so the best-selling year always looks like the worst car. Dividing by the number of production runs strips sales volume out and leaves the fault rate.
| Model year | Per run | Complaints | Runs | Enough history? |
|---|---|---|---|---|
| 2012 | 14 | 8 | yes | |
| 2003 | 50 | 22 | yes |
Among the 2 Infiniti FX35 years with enough history, the three to walk away from are 2003, 2012; the three worth hunting are 2012, 2003. Anything marked «too new» sits outside the ranking on purpose — complaints keep arriving for a decade after a car is sold, so a 2026 build would look flawless next to a ten-year-old one and comparing them would be dishonest.
When it starts to break
Not the calendar year the complaint was filed — the age of the car when it failed. That age decides who pays: inside the warranty the manufacturer does, outside it you do.
| Age at failure | Complaints | Running total | Warranty |
|---|---|---|---|
| 0 years | 7% | covered | |
| 1 year | 10.5% | covered | |
| 2 years | 14% | covered | |
| 3 years | 15.8% | covered | |
| 4 years | 24.6% | you pay | |
| 5 years | 35.1% | you pay | |
| 6 years | 42.1% | you pay | |
| 7 years | 49.1% | you pay | |
| 8 years | 57.9% | you pay | |
| 9 years | 68.4% | you pay | |
| 10 years | 75.4% | you pay | |
| 12 years | 77.2% | you pay | |
| 13 years | 86% | you pay | |
| 14 years | 96.5% | you pay | |
| 15 years | 100% | you pay |
Basic warranty on this car is 4 years / 50,000 miles. Only 15.8% of reported failures happen inside it — the remaining 84.2% come out of the owner's pocket. Powertrain cover (6 years / 70,000 miles) reaches further, but it only covers engine and transmission, and most complaints here are not either.
What actually fails — and at what age
Ordered by how often owners reported each system, with the age at which it typically goes. What waits further out is Air Bags at 10.1 years — past every basic warranty, and the bill lands on whoever owns the car then.

What else in this class
Same vehicle class as the Infiniti FX35, so the comparison is fair — an estate against an estate, not against a coupé. These 6 share its class; open any of them to see its own build years and failure ages side by side with the FX35.
| Same class as the FX35 | Complaints on record | Recall campaigns | Years built |
|---|---|---|---|
| Subaru Outback | 137 | 2005–2026 | |
| Toyota Land Cruiser | 85 | 1981–2026 | |
| Subaru Forester | 121 | 1998–2026 | |

| Honda Element | 100 | 2003–2011 | |
| Jeep Liberty | 80 | 1993–2013 |

How we measure it
Reliability scores usually arrive as a number out of five with no working shown. The Infiniti FX35 figure here comes out of 64 individual reports, and here is exactly how they were turned into a rate — two steps in it are arguable and you should be able to argue with them.
Rate, not total. Volume alone would decide the ranking, so we divide by the number of production runs — the distinct first-eleven-character VIN prefixes on record. The Infiniti FX35 alone splits into 30 runs carrying 64 complaints — 2.13 per run against 3.73 for the market.
Age, not year. Incident date minus model year gives the age at failure, which is what the warranty question turns on. It is why our «worst year» rankings exclude anything built in the last 6 years — those cars simply have not had time to break yet.
What this is not. Filing with a federal regulator takes effort, so what you see are faults someone judged serious — not scratched paint, not running costs, not how nice the car is to live with. For the Infiniti FX35 the file runs from 2003 to 2012, so the older years carry a full life of reports and the newest carry almost none.
