When it starts to break
| Age at failure | Complaints | Running total | Warranty |
|---|---|---|---|
| 3 years | 50% | you pay | |
| 5 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 the engine and transmission, which account for few of the complaints here.
What actually fails — and at what age
On the McLaren 720S, the early trouble is Unknown Or Other — reported at around 3 years, so a car still under warranty is the one to check for it. What waits further out is Suspension at 5 years — past every basic warranty, and the bill lands on whoever owns the car then.
| System | Complaints | Typical age | Crash | Fire |
