What is the actual lifespan of Nissan's CVT transmission?

Nissan's CVT transmission can last between 400,000 to 500,000 kilometers, but minor issues typically start appearing after 100,000 kilometers. Here's more information about CVT transmissions: 1. CVT refers to a type of automotive transmission, also known as a continuously variable transmission. It mainly consists of two conical pulleys and a steel belt or chain. The two conical pulleys can be tightened or loosened via electronically controlled hydraulic pressure, changing the diameter of the steel belt wrapped around them to achieve different gear ratios. During startup, the driving pulley has the smallest diameter while the driven pulley has the largest diameter; during high-speed driving, the driving pulley's diameter increases while the driven pulley's diameter decreases. The entire diameter-changing process is controlled by a computer, enabling seamless and stepless adjustment. 2. CVT transmissions provide excellent fuel efficiency for vehicles, ensuring smooth driving experiences while effectively reducing emissions.
The actual lifespan of Nissan's CVT transmission varies from person to person, but based on my experience driving Nissan cars, most start having issues between 120,000 to 180,000 kilometers. My old Sylphy began experiencing transmission vibrations and rough shifting at 150,000 km, and the mechanic said it was due to internal chain wear, costing several thousand to repair. A friend's Qashqai had similar issues, with severe slipping at 180,000 km. CVT designs are inherently less durable than traditional transmissions, especially since Nissan cuts corners on cooling to save costs. Avoid aggressive acceleration and change the specialized fluid every 40,000 km to slightly extend its life. But honestly, don’t expect it to last beyond 200,000 km—get it checked immediately if problems arise, or you risk dangerous stalling on the road.
