The McLaren 650S draws 1 complaints per production run against 3.73 for the average car — better than typical. Failures cluster at 4 years, so only 0% of them fall inside the 3-year basic warranty.
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 |
|---|---|---|---|
| 4 years | 100% | you pay |
Basic warranty on this car is 3 years / 36,000 miles. Only 0% of reported failures happen inside it — the remaining 100% come out of the owner's pocket. Powertrain cover (5 years / 60,000 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. On a McLaren 650S the early trouble is Air Bags and Exterior Lighting — reported at around 4 years, so a car still under warranty is the one to check for it.
| System | Complaints | Typical age | Crash | Fire |
|---|---|---|---|---|
| Air Bags | 4 yrs | — | — | |
| Exterior Lighting | 4 yrs | — | — |

How we measure it
Reliability scores usually arrive as a number out of five with no working shown. The McLaren 650S figure here comes out of 2 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 McLaren 650S alone splits into 2 runs carrying 2 complaints — 1 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 McLaren 650S the file runs from 2015 to 2015, so the older years carry a full life of reports and the newest carry almost none.
