Procon and Workshops Reveal the 4 Car Brands That Accumulate the Most Complaints in Brazil in 2025, with Mechanical Failures, Problematic Transmissions, and Criticized After-Sales.
The Brazilian automotive market is undergoing significant transformations, with the arrival of hybrid and electric cars and a strong expansion of compact SUVs. However, amidst so much innovation, one problem remains constant: consumer complaints against manufacturers. Data from the National Consumer Defense Information System (Sindec/Procon), combined with surveys from authorized workshops and reports from owners in 2025, reveal that some brands stand out negatively due to the volume of complaints.
This list is not just a ranking but a portrait of the dissatisfaction of drivers facing mechanical failures, after-sales issues, and high maintenance costs. Below, you can see which are the 4 car brands that accumulate the most complaints in Brazil in 2025 and the reasons that put them at the top of this survey.
Fiat: Volume Champion but Criticized for High Maintenance Costs
Fiat continues to be the market leader in Brazil, with popular models such as Argo, Cronos, Strada, and Pulse among the best-selling.

-
Fiat works miracles in the Brazilian market, lowers the price of its 0 km hatch to R$ 69,990, reestablishes the model as the cheapest car in the country, and reignites the battle against Kwid and C3.

Fiat launches the new 2027 Toro hybrid with 48V, 176 hp, an electric motor of 15.5 hp, a 0.85 kWh battery, up to 7% fuel savings, 8% fewer emissions, and possible exemption from IPVA.
However, precisely because it has a huge consumer base, it also concentrates a high number of complaints recorded with Procon and in workshops.
The main points of complaint in 2025 include:
- Automated GSR Transmission in used models, which continues to be criticized even after its discontinuation;
- Expensive electronic parts that are difficult to replace in recent models;
- Reports of high fuel consumption in some SUVs such as the Pulse and Fastback.
Independent workshops also highlight that the cost of maintenance has increased in the last two years, generating dissatisfaction among customers who chose the brand precisely for its cost-benefit. Despite this, Fiat maintains a strong appeal in the PCD and fleet markets, which explains part of the loyalty even with so many complaints.
Volkswagen: Transmissions and Electronics at the Center of Criticism
Volkswagen appears as the second brand with the most registered complaints in Brazil in 2025. Although it has well-established models, such as the Polo, T-Cross, and Nivus, many consumers report problems ranging from embedded electronics to defects in Tiptronic and DSG automatic transmissions.
According to data from Procon and reports in workshops, the main points of dissatisfaction are:
- DSG Transmission in Used Cars: overheating, vibrations, and high repair costs;
- Electrical Problems in multimedia centers and driver assistance systems;
- Complaints about high prices for original parts.
For workshops, the T-Cross and Virtus models frequently appear for maintenance service regarding transmissions, while owners complain that the wait time for parts can exceed weeks at some dealerships.
Chevrolet: After-Sales and Constant Recalls
Chevrolet, another giant in Brazil, also ranks among the brands that receive the most complaints in 2025. With popular models like Onix, Tracker, and S10, the manufacturer faces criticism mainly related to after-sales.
According to the gathered data:
- Many customers report slow service at dealerships, especially in rural areas;
- There are recurring complaints about delays in recall processes, as occurred with airbags and injection system problems;
- Independent workshops point out that the Tracker 1.0 turbo is the leader in records of failures in turbines and fuel pumps.
Additionally, consumers complain that depreciation in some models, such as Cobalt and Spin, is more pronounced compared to rivals.
Renault: Cost of Parts and Durability Questioned
Closing the list is Renault, which has highly popular models in Brazil, such as Kwid, Logan, and Duster.
Despite affordable prices and appeal among app drivers, the brand accumulates a large volume of complaints mainly linked to part durability.
Among the main reported problems are:
- Fragile Suspension in Logan and Sandero, which require frequent replacements;
- Expensive replacement parts compared to the car’s value;
- Complaints about the CVT automatic transmission, which requires costly maintenance on older models.
Authorized workshops highlight that the Kwid and Logan models are common in suspension and clutch repairs, affecting the cost for owners seeking economy.
Industry Trends: Electrification Could Change the Ranking
Automotive market experts point out that this landscape may change in the coming years with the arrival of hybrid and electric vehicles. Manufacturers such as BYD, GWM, and even Toyota itself have fewer complaints in 2025, but still do not represent significant volumes in the market to feature among the most complained brands.
Additionally, consumer defense agencies note that complaints are not only related to technical failures but also to relationship issues. Delays in parts delivery, lack of transparency in recalls, and poor after-sales service weigh as heavily as mechanical defects.
What Does This Mean for the Consumer?
Knowing which brands accumulate the most complaints can serve as a warning for those considering buying a car in 2025, whether new or used.
The choice of a vehicle should not only take price or design into account but also mechanical reliability, maintenance costs, and the brand’s reputation in customer service.
In the end, there is no perfect car: even the most complained brands have models that are well-rated in durability. The key issue is that consumers stay informed, research before buying, and assert their rights if they face problems.
Com relação ao Logan da Renault discordo pois tenho um 14/15 1.6 nunca deu problema algum e todas as vezes que precisei fui bem atendido
Pq vc não teve não significa que outros motoristas tiveram a mesma sorte.
