Chevrolet Onix: Common Problems & Reliability
Overview
The Chevrolet Onix has been one of Latin America’s best-selling cars for years, so its reliability is well understood. The first generation (2012–2019) is simple and durable. The second generation’s 1.0 turbo engine is efficient and lively but, like other small turbos, is sensitive to oil condition and can develop carbon and oil-consumption issues if neglected. Common complaints centre on ignition/misfire, suspension wear on rough roads, and multimedia electronics.
Most common problems
| Problem | Severity | Typically at | Rough cost |
|---|---|---|---|
| Oil consumption / carbon (1.0 turbo, gen 2) The turbo three-cylinder can consume oil and build intake carbon if oil changes are stretched; check the level regularly and service on time.

| Ignition coil / spark plug misfire Worn plugs or a weak coil cause a misfire and rough idle — a common, low-cost fix. Related code: P0300 🔧 Doing it yourself? Buy the part: Spark plugs · Ignition coil | medium | after ~60,000 km | $60–$250 |
| Front suspension / strut mount wear Knocks and clunks from front struts and mounts are common, especially on poor roads. | low | after ~60,000 km | $120–$400 |
| MyLink multimedia / electrical glitches Screen freezes, reboots and connectivity issues are frequently reported; updates and connector cleaning help. | low | — | $0–$250 |
| Air-conditioning / compressor issues Weak cooling or a noisy compressor can develop with age; a recharge and inspection usually resolves it. | low | — | $80–$400 |
Years / engines to watch
Neglected gen-2 1.0-turbo cars (oil-change history unknown) are the riskiest; the simpler gen-1 cars are very forgiving.
Maintenance tips to avoid trouble
- On the 1.0 turbo, check oil level often and never stretch oil-change intervals.
- Replace spark plugs and inspect coils on schedule.
- Service front suspension and mounts if you drive rough roads.
- Keep MyLink software updated to reduce glitches.
