The BMW 325iS draws 1.29 complaints per production run against 3.73 for the average car — better than typical. The worst model year is 1992 at 1.75 complaints per run; the best is 1994 at 1 — a 1.8-fold gap between two cars wearing the same badge. Failures cluster at 8 years, so only 4.8% of them fall inside the 4-year basic warranty.
BMW 325iS years to avoid — and the best ones
The BMW 325iS year to avoid is 1992, at 1.75 complaints per production run. The best is 1994 at 1 — 1.8 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? |
|---|---|---|---|---|
| 1995 | 4 | 4 | yes | |
| 1994 | 5 | 5 | yes | |
| 1993 | 11 | 9 | yes | |
| 1992 | 7 | 4 | yes |
Among the 4 BMW 325iS years with enough history, the three to walk away from are 1992, 1993, 1994; the three worth hunting are 1995, 1994, 1993. 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 |
|---|---|---|---|
| 3 years | 4.8% | covered | |
| 4 years | 14.3% | you pay | |
| 5 years | 23.8% | you pay | |
| 6 years | 42.9% | you pay | |
| 7 years | 47.6% | you pay | |
| 8 years | 61.9% | you pay | |
| 10 years | 76.2% | you pay | |
| 11 years | 90.5% | you pay | |
| 14 years | 100% | you pay |
Basic warranty on this car is 4 years / 50,000 miles. Only 4.8% of reported failures happen inside it — the remaining 95.2% come out of the owner's pocket. Powertrain cover (4 years / 50,000 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 Structure at 8.8 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 BMW 325iS, 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 325iS.
| Same class as the 325iS | Complaints on record | Recall campaigns | Years built |

How we measure it
Reliability scores usually arrive as a number out of five with no working shown. The BMW 325iS figure here comes out of 27 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 BMW 325iS alone splits into 21 runs carrying 27 complaints — 1.29 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 BMW 325iS the file runs from 1992 to 1995, so the older years carry a full life of reports and the newest carry almost none.
