Basic warranty on this car is 4 years / 50,000 miles. Only 99% of reported failures happen inside it — the remaining 1% 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 11% of the complaints here.
What actually fails — and at what age
On the BMW iX, the early trouble is Electrical System and Forward Collision Avoidance — reported at around 0.6 years, so a car still under warranty is the one to check for it.

|---|---|---|---|---|
| Electrical System | 0.6 yrs | 3 | 2 | |
| Forward Collision Avoidance | 0.6 yrs | 16 | 1 | |
