What is the failure rate of Baojun CVT transmission?
3 Answers
Baojun CVT transmission has a relatively low failure rate. With proper maintenance, its service life can reach up to 300,000 kilometers. The main components of the CVT system include the driving pulley set, driven pulley set, metal belt, and hydraulic pump. This type of transmission uses a belt and variable-diameter pulleys to transmit power, achieving optimal matching between the transmission system and engine conditions. Below are the advantages of CVT continuously variable transmission: Smooth driving without jerking: Since there are no traditional automatic transmission gears, the gear-shifting jerking sensation is eliminated. Therefore, the power output of the CVT transmission is linear, providing an exceptionally smooth driving experience. More flexible gear setting: Theoretically, a CVT transmission system can have an unlimited number of gears, allowing for more flexible gear settings. It easily achieves a balance between gear ratio, speed ratio, performance, fuel consumption, and exhaust emissions in traditional transmission systems. High fuel efficiency: The mechanical efficiency and fuel economy of CVT transmission are significantly better than those of conventional automatic transmissions, second only to manual transmissions, making it much more fuel-efficient.
I've repaired quite a few Baojun models with CVT transmissions. The overall failure rate isn't extremely high but also not low. Common issues include steel belt slippage or control unit malfunctions, which can lead to jerky shifting or power interruption. Baojun typically sources its CVTs from budget suppliers, such as those used in some 510 or 530 models. Owner feedback indicates that prolonged driving with high oil temperatures may accelerate wear. Regular transmission fluid changes and avoiding aggressive driving can significantly reduce the likelihood of problems. If you notice unusual noises or lack of power during acceleration, I recommend getting it checked early rather than waiting until after the warranty expires. Overall, the failure rate is heavily influenced by maintenance—proper care will help it last much longer.
As a Baojun owner, I've been driving the CVT version 510 for three years and feel the failure rate varies by individual. My car has had no major issues, but some in my social circle complain about rough shifting or transmission overheating failures. Economy car CVTs may use simpler materials, resulting in slightly higher failure rates compared to premium brands, especially in congested urban driving. I strictly adhere to oil changes every 20,000 km, which prevents many issues. Online forum discussions show Baojun CVT failures were concentrated in early production batches, with newer models showing improvements. The key is choosing the right maintenance shop and avoiding cheap, low-quality oils.
