I bought a used mini MPV Nissan Tino, 8 yrs old. It is running with Hyper CVT, I have some problem when running for more then 20 min or running with higher speed like 100 km/h. The car will jerk a while like transmission is shifting up and down and later I can notice that the rpm is higher then before. when stop down and start to move, feel no power at all, it just like stay at 3rd gear of normal AT. I stop the car and start the engine, the "sport" light will blink for 16 times but with constant timing, no improvement after restart the engine. However, it will back to normal when the car is left to cool down and restart, everything back to normal.
