Lexus UX years to avoid — and the best ones

| 2020 | 5 | 5 | yes |
When it starts to break
| Age at failure | Complaints | Running total | Warranty |
|---|---|---|---|
| 2 years | 22.2% | covered | |
| 3 years | 33.3% | covered | |
| 4 years | 77.8% | you pay | |
| 6 years | 100% | you pay |
Basic warranty on this car is 4 years / 50,000 miles. Only 33.3% of reported failures happen inside it — the remaining 66.7% come out of the owner's pocket. Powertrain cover (6 years / 70,000 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 Lexus UX, the early trouble is Service Brakes and Air Bags — reported at around 4 years, so a car still under warranty is the one to check for it. What waits further out is Visibility at 6 years — past every basic warranty, and the bill lands on whoever owns the car then.
