Ford Bronco II Reliability

Ford Bronco II years to avoid — and the best ones

The Ford Bronco II year to avoid is 1988, at 1.7 complaints per production run. The best is 1990 at 1.2 — 1.4 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.

Among the 5 Ford Bronco II years with enough history, the three to walk away from are 1988, 1986, 1989; the three worth hunting are 1990, 1987, 1989. 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.

What actually fails — and at what age

Systems by number of complaints, with the age at which each typically goes. The age column is the useful one — it tells you what to expect next on a car you already own, and what to inspect on one you are about to buy.

What else in this class

Same vehicle class as the Ford Bronco II, 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 Bronco II.

These are totals, not rates: a model that sold in millions collects more of both. Open one to see its complaints per production run — the figure this site is built on.

How we measure it

Reliability scores usually arrive as a number out of five with no working shown. The Ford Bronco II figure here comes out of 150 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 Ford Bronco II alone splits into 107 runs carrying 150 complaints — 1.4 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 Ford Bronco II the file runs from 1984 to 1990, so the older years carry a full life of reports and the newest carry almost none.
