If you are thinking about buying a car, whether new or used, you know that the right choice can mean savings and peace of mind — while the wrong one can turn into a mechanical and financial nightmare.
As someone who has closely followed the Brazilian automotive market, I decided to create this guide to help you avoid problematic models and make an intelligent decision. 10 cars that give the most defects in Brazil, based on consumer complaints, data from Procon and reports from specialized workshops.
🚗 Why Are Some Cars So Problematic?
Before listing the models, it is crucial to understand what makes a car prone to defects. Chronic manufacturing problems, lack of “tropicalization” for Brazilian conditions (such as irregular roads and intense traffic), neglected maintenance and poorly executed technological complexity are key factors.

🔥 The 10 Cars That Give the Most Defects in Brazil
Here is the list of models leading in complaints in 2025, based on data from Procon, NHTSA (American agency) and reports from mechanics:
10. Nissan Kicks (with CVT transmission)
Most common problems: Overheating of the CVT transmission, jerks when changing gears and loss of power.
Repair cost: Between R$ 10 thousand and R$ 15 thousand.
Why avoid: Despite being a popular SUV, its CVT transmission cannot handle Brazil's intense urban traffic.
9. Honda Civic (2016-2020 generations with CVT)
Most common problems: Premature wear of the CVT belt, slipping of the gearbox and risk of locking.
Repair cost: Can reach R$ 18 thousand.
Why avoid: Honda has a reputation for reliability, but these generations of Civic have tarnished that reputation.
8. Volkswagen Golf and Jetta (with DSG transmission)
- Most common problems: Overheating of the mechatronic module, jerks and total transmission failure.
- Repair cost: Between R$ 15 thousand and R$ 18 thousand.
- Why avoid: The DSG gearbox is sensitive to heat and intense traffic, common in large Brazilian cities.
7. Ford Focus (with Powershift transmission)
- Most common problems: Double clutch failures, faulty electronic module and loss of acceleration.
- Repair cost: Up to R$ 14 thousand.
- Why avoid: This model has already been the target of lawsuits and recalls.
6. Chevrolet Onix Plus (first units with 6-speed automatic transmission)
- Most common problems: Transmission oil pump failure, overheating and accelerated wear.
- Repair cost: Between R$ 8 thousand and R$ 12 thousand.
- Why avoid: Despite being one of the best-selling cars, the first automatic units are problematic.
5. Renault Captur (with CVT)
- Most common problems: Overheating on long journeys, loss of pressure in the gearbox and risk of “melting” the transmission.
- Repair cost: Between R$ 9 thousand and R$ 13 thousand.
- Why avoid: Owners in hot regions, such as the Northeast, report frequent problems.
4. Jeep Renegade (with 6 or 9-speed automatic transmission)
- Most common problems: Leak in the heat exchanger, overheating and jerks when changing gears.
- Repair cost: Can reach R$ 20 thousand.
- Why avoid: Chronic factory defects and high repair costs make this SUV risky.
3. Sonata 2011
- Most common problems: Engine stalling, serious electrical defects and problems with airbags.
- Repair cost: Up to US$ 5 thousand (about R$ 25 thousand) .
- Why avoid: This model has accumulated more than 5,000 complaints with the NHTSA, making it a high-risk choice.
2. 2011 Jeep Grand Cherokee
- Most common problems: Recurrent electrical problems, engine and brake system failures.
- Repair cost: High maintenance and unpredictable costs.
- Why avoid: Jeep's robustness does not apply to this model, which suffers from below-average reliability.
1. 2013 Nissan Altima
Most common problems: Faults in the CVT transmission, noises in the power steering pump and defects in the windshield.
Repair cost: Up to US$ 3,300 (about R$ 16 thousand).
Why avoid: With 3,000 complaints to the NHTSA, this sedan is synonymous with high and unforeseen costs.
💡 Why Are These Models Problematic?
Most problems are related to complex automatic transmissions (CVT, DSG and Powershift), which were not fully adapted to Brazilian conditions. design flaws, such as insufficient cooling systems and the use of low-durability materials, worsen the situation. neglected preventive maintenance — many drivers ignore changing the transmission oil, believing in the “oil for life” myth.
✅ Conclusion: Invest in Reliability
