At the end of 2019, the debut of the second installment of the Chevrolet Onix It completely transformed the rules of the game in the region. What was previously a basic and compliant car evolved into a proposal that forced its rivals to step up to the plate in terms of technology and passenger protection. However, the passage of time and massive filming have made it clear that, despite its virtues, this model is not free of “sins” mechanics.
If you are looking for a second-hand unit in markets such as Chile, Mexico, Brazil or Colombia – or if you already keep one in your garage and suspect some unusual behavior – this x-ray is essential. We gather direct experiences from expert mechanics, user communities, and factory alerts to tell you what’s really going on under the hood of a Onyx.
What versions and engines does this article analyze?
This technical breakdown focuses specifically on the architecture GEM (Global Emerging Markets)covering all units manufactured during the period 2019-2022.
Engines: The analysis covers from the dynamic 1.0 3-cylinder turbo (the soul of the Premier and RS variants) to the 1.2 atmospheric (protagonist on the streets of Mexico and Colombia) and the efficient 1.0 aspirated (the favorite of the Brazilian market).
Transmission Systems: Evaluations are included for both the boxes 5 and 6 ratio manuals as for the 6 speed automatic.
Bodies: The information is valid for both silhouettes in the catalog: the youth Hatchback and the family Sedan (baptized as Onix Plus in various territories).
Common faults of the Chevrolet Onix (2019–2022)
1. The ghost of fire: Recall 2019-2020
It is inevitable to review the history of this model without stopping at the massive recall that marked its first steps on the market.
The origin: A mismatch in the engine programming (mapping) generated excess pressure and heat in the cylinders. In extreme situations, this fractured the piston, allowing oil to escape towards incandescent components, sparking fires.
Appearance: It manifested itself in vehicles practically from the dealership or with very little run-in.
Risk level: Critical. The vast majority of the specimens were cleaned in official workshops. If you are interested in a 2019 or 2020 model, it is mandatory to confirm that the software patch has been applied.
2. Submerged timing belt: The Achilles heel
This technical design is the most determining factor for the useful life of the 1.0 Turbo and 1.2 engines.
The origin: The belt runs inside the crankcase to minimize friction. However, using an oil that does not meet exact standards or extending maintenance periods breaks down the rubber. These debris clog the suction of the oil pump, causing the engine to seize due to lack of flow.
Appearance: Serious failures usually arise after 60,000 km if there was negligence in the lubricant.
Risk level: Very High. Engine survival depends on the exclusive use of synthetic oil Dexos 1 Gen 2 or Gen 3.
3. Electronic elves and the MyLink interface
Although its connectivity is enviable for its category, digital management usually presents certain “whims.”
The origin: Screens that lock, unexpected interruptions with the smartphone and, sometimes, excessive consumption that drains the factory battery prematurely.
Appearance: It can happen at any time, even from the first 10,000 km.
Risk level: Low/Medium. It is usually corrected with a software refresh or by installing a higher capacity battery.
4. Automatic gearbox: Jumps or abrupt transitions
Although the 6-speed transmission is typically robust, not all owners have had a smooth experience.
The origin: Sensation of “kicking” or jerking when changing between first and second, or when downshifting. Typically, the culprit is an out-of-calibration pressure sensor or the need for a new version of the module (TCM) software.
Appearance: It has been documented in the range of 30,000 to 50,000 km.
Risk level: Half. In most cases, this is an electronic adjustment and not an internal breakage of the case.
5. Wear on the running gear and braking
The car is urban by nature, but the punishment of Latin American potholes accelerates the wear of certain components.
Suspension: Sharp knocks at the front, usually from the stabilizer bar bushings or linkages.
Brakes: Short pad life (sometimes they last less than 20,000 km) and metallic squeaks due to dust entering the mechanism.
Risk level: Low. They are routine maintenance details that do not cost a fortune.
6. Adjustment noises in the cabin (“Crickets”)
The origin: The predominance of rigid plastics makes it easy for small sounds to arise in the console, door panels and central pillars with daily vibration.
Risk level: Aesthetic. It doesn’t compromise the integrity of the car, but it can be annoying if you’re looking for a quiet driving experience.
Reliability Summary and Key Points
Power Plant (Turbo): Moderate Incidence / Critical Risk. Requires absolute discipline in maintenance and the use of sealed lubricant Dexos.
Electrical System: Frequent Incidence/Slight Risk. These are mainly programming errors in the interface MyLink.
Automatic Box: Low Incidence / Moderate Risk. It is essential to confirm that the gear transitions are fluid during the test drive.
Running and Braking Gear: Moderate Incidence/Slight Risk. It presents a natural deterioration that is accentuated by the irregular conditions of the regional asphalt.
Specialist Verdict
He Chevrolet Onix (2019-2022) It stands out as an outstanding option if you value gas savings and onboard protection, especially since its 6 factory airbags broke the mold in its category. However, the performance of your turbo engine depends directly on meticulous maintenance. A carelessness by the previous owner with the type of lubricant or ignoring recalls can turn a good purchase into a headache.
Closing recommendation: When exploring the second-hand market, give preference to units Chevrolet that they have their maintenance log stamped by the dealer. Also, don’t forget to take a look at the oil filler cap; A visual inspection of the timing belt can tell you a lot about the actual health of the engine.
