Chevrolet Onix

Brazil's best-selling car for most of a decade, and the highest-volume Chevrolet in South America — a car almost invisible in Western sources despite that. Flex-fuel is the fact that changes its diagnosis: it runs on any mix of petrol and ethanol, so long-term fuel-trim adapts across a range that would read as a fault on a petrol-only car, and a cold-start complaint is often an ethanol starting-aid question rather than an ignition one. The 1.0 turbo three-cylinder is the current volume engine.

Service information

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:

  • The car — make, model, year and engine. The same fault behaves differently on each.
  • What you measured, not only what you replaced.
  • What actually fixed it — or that nothing did, which is worth knowing too.
