The Oil-Coated Timing Belt of Chevrolet Should Last Longer, But Drivers Complain That It Does Not Go Beyond 100 Thousand KM. GM Replies, Blaming the Incorrect Use of Oil, But Customers Disagree. Now, the Manufacturer Draws Up a Plan to Try to Contain the Anger of Owners!
Owners of the Chevrolet Onix have been complaining about problems with the car’s timing belt, which, although designed to last over 200 thousand kilometers, shows failures before reaching 100 thousand.
GM responded by claiming that vehicle maintenance does not follow the recommendations in the manual, but announced actions to support consumers. The information comes from the portal Auto Papo.
The Chevrolet Onix, one of the best-selling cars in Brazil, is facing a controversy related to its timing belt.

Various owners of the model have complained that the component, which should have a lifespan of over 200 thousand kilometers, starts to show problems soon after 100 thousand.
The case has sparked protests from consumers claiming that the defect compromises the reliability and durability of the vehicle, which could further harm the brand’s image.
The main reason for the complaints revolves around the timing belt of the Onix, which is oil-coated, and which, according to the owners, is not meeting the durability expectations promised by the manufacturer.
Normally, the component of a modern engine of this type should have a lifespan of over 200 thousand kilometers, but in the case of the affected cars, the item begins to show wear much earlier, around 100 thousand kilometers.
According to GM
The explanation for the problem lies in the way owners have been maintaining their vehicles.
The manufacturer claims that the oil used in the engine does not follow the specifications in the manual, which could compromise the integrity of the timing belt.
According to GM, it is not enough that the oil has the indicated viscosity and additives, as the vehicle owners claim.
The manufacturer emphasizes that the oil used must be from the brand recommended in the owner’s manual, as it contains an essential additive to protect the rubber of the belt and prevent the oil from attacking the material.
This explanation, however, has not been well received by the owners.
Many claim they use the oil indicated by GM, regarding both viscosity and additives.
In addition, they point out that the quality of the product should be sufficient to ensure the durability of the belt without the need for a specific oil from a manufacturer-defined brand.
GM Has Not Ignored the Complaints
And, to deal with the situation, it is taking steps to support Onix owners facing this problem.
The company announced it is organizing an initiative aimed at providing technical support and assistance to affected consumers, intending to alleviate repair costs and prevent greater damage to the vehicles.
The controversy surrounding the timing belt of the Onix has already generated a lot of buzz on social media, with consumers questioning GM’s stance and the quality of the components used in the model.
For some, the manufacturer’s explanation seems evasive, and many believe that the durability of the belt should be higher, regardless of maintenance conditions.
After all, the timing belt, although a wear item, plays a fundamental role in the proper functioning of the engine and should have a durability compatible with other components of vehicles in the same category.

The Debate Surrounding This Problem Also Raises Questions About Consumer Expectations Regarding Modern Cars
With the evolution of automotive technology, it is expected that vehicles like the Onix, which are mass-produced and sold at affordable prices, offer good cost-benefit over time.
This includes the durability of key components such as the engine, transmission, and, of course, the timing belt.
The fact that the Onix is a popular model in Brazil makes consumers more attentive to any failures or defects, especially in components fundamental to the car’s operation.
The situation of the timing belt of the Onix adds to other problems faced by consumers regarding the quality of components in popular vehicles.
Issues such as failures in parts that should be more durable, like the suspension, braking system, and now the timing belt, generate discomfort among drivers and directly impact brand perception.
After all, a car that presents recurring problems in essential components can lead to a loss of consumer trust.
In Response to This Scenario, GM Reaffirms That the Durability of the Onix’s Timing Belt Is Compatible with the Manual Specifications
However, the manufacturer also understands that the consumer experience is fundamental and is working to adjust its service and support processes.
The manufacturer has not yet revealed specific details about the assistance that will be offered to owners but promises effective solutions for those facing problems with the timing belt of the model.
Additionally, the case also raises discussion about the importance of preventive maintenance and the choice of the correct products to ensure the good performance and longevity of the car.
The consumer often has the right to expect that the information provided by the manufacturer, especially those present in the owner’s manual, is sufficient to ensure that the vehicle operates reliably and durably.
The problem faced by Onix owners, therefore, can be seen as a wake-up call for the importance of transparency in the guidance provided by car manufacturers.
