Basic warranty on this car is 4 years / 50,000 miles. Only 43.5% of reported failures happen inside it — the remaining 56.5% come out of the owner's pocket. Powertrain cover (4 years / 50,000 miles) reaches further, but it only covers the engine and transmission, which account for about 33% of the complaints here.
What actually fails — and at what age
On the Jaguar XJ, the early trouble is Service Brakes and Hydraulic — reported at around 3.5 years, so a car still under warranty is the one to check for it. What waits further out is Electrical System at 9 years — past every basic warranty, and the bill lands on whoever owns the car then.
| System | Complaints | Typical age | Crash | Fire |
|---|---|---|---|---|
| Service Brakes | 3.5 yrs | 1 | — | |
| Hydraulic | 1.3 yrs | 1 | — | |
| Vehicle Speed Control | 2 yrs | — | — | |
