Even with a history of heavy criticism, some automakers insist on technologies that could jeopardize consumer confidence. Recurring mechanical failures, such as those caused by problematic transmissions and oil-soaked timing belts, continue to appear in recent models. These automotive engineering choices have been a warning to attentive drivers.
The Instagram profile of Dr. Mauro Costa, known for revealing curiosities and warning about automotive pitfalls, raised the red flag once again. Among the highlights of the analysis are vehicles that run the risk of becoming real headaches for their owners. Check out some examples of cars with chronic problems.
Hyundai Creta Ultimate 1.6 Turbo with DCT transmission
The Hyundai Creta Ultimate 1.6 turbo, one of the cars with chronic problems, equipped with a dry dual-clutch gearbox, is among the brand's risky bets. Despite promising improvements, this technology already has an unreliable history in Brazil, with frequent jolts and overheating in models from other brands, such as Ford and Volkswagen.
Especially in large cities, where traffic requires constant gear changes, the transmission can suffer premature wear, compromising its durability and increasing maintenance costs. Even with Hyundai's guarantees of improvement, the DCT transmission still raises doubts.

Chevrolet Onix and Onix Plus 1.0 three cylinders
The Chevrolet Onix and Onix Plus models, with three-cylinder engines, use the controversial oil-immersed timing belt. Although it offers benefits such as reduced noise and greater durability, it requires extra care. If the oil is not in good condition, the belt can deteriorate quickly, causing serious damage to the engine.
Reports of engine failures due to belt problems have already emerged, making cars with chronic problems a growing concern among drivers. Chevrolet reinforces the need to strictly follow the manual's guidelines to avoid losses.
Caoa Chery Tiggo 5X until 2022
Until 2022, Caoa Chery's Tiggo 5X was equipped with a dry dual-clutch transmission, similar to Ford's infamous Powershift. Problems such as overheating and jerking left many consumers frustrated.
Starting in 2022, the automaker switched to a CVT transmission, seeking greater reliability. However, those who own the previous models need to be careful, as transmission headaches are still a real risk.
Ford Ranger 2.0 turbodiesel
The Ford Ranger's 2.0-liter turbodiesel engine uses the same oil-immersed timing belt found in other troubled models. When not properly maintained, this part can wear out quickly, accumulating debris and compromising the engine.
For those who depend on their Ranger for long trips or heavy-duty work, the cost of improper maintenance can be high. This makes the Ranger, one of the cars with chronic problems, yet another example of engineering that has yet to prove its robustness.
Chevrolet Montana three cylinders
Following the same line, the Chevrolet Montana with a three-cylinder engine adopts an oil-immersed timing belt. Although modern and silent, the durability of the part in adverse conditions leaves something to be desired. For drivers who use their cars intensively, the risk of wear is a reality that cannot be ignored.
Alert for drivers
Choosing a vehicle involves more than just design and price. Mechanical reliability and the engineering behind the design are key factors in avoiding frustrations and unexpected costs. Pay attention to expert recommendations and, whenever possible, research the models before investing.
With cars with chronic problems increasingly in evidence, the consumer needs to be informed and ready to make safer decisions when buying. After all, no one wants a “bomb” parked in the garage.
Who would have thought that GM would include an engine of this size (oil-immersed belt) in its cars? It has completely lost confidence!
Just use the oil and carry out the changes according to the Manual. It is so reliable that GM has increased the warranty for the part.
It's easy to talk. The hard part is changing people's perceptions. Proof of this is the drop in sales.
