The Chevrolet Onix draws 1 complaints per production run against 3.73 for the average car — better than typical. Failures cluster at 1 years, so only 100% 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 |
|---|---|---|---|
| 1 year | 100% | covered |
Basic warranty on this car is 3 years / 36,000 miles. Only 100% of reported failures happen inside it — the remaining 0% 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 Chevrolet Onix the early trouble is Air Bags — reported at around 1 years, so a car still under warranty is the one to check for it.
| System | Complaints | Typical age | Crash | Fire |
|---|---|---|---|---|
| Air Bags | 1 yrs | 1 | — |

How we measure it
Reliability scores usually arrive as a number out of five with no working shown. The Chevrolet Onix figure here comes out of 1 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 Chevrolet Onix alone splits into 1 runs carrying 1 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 Chevrolet Onix the file runs from 2021 to 2021, so the older years carry a full life of reports and the newest carry almost none.
