Does CVT Have Jerking Sensation?

"The charging fan of new energy vehicles will keep making noise. This is because charging the vehicle can easily cause the battery pack to overheat. When the internal sensors of the battery detect the temperature, they will send an alarm to the BMS (Battery Management System). The BMS will then send a signal to the fan, which will activate the fan control terminal to start the fan. Once overloaded, the noise from the vehicle's fan will become very loud. Reasons for noise during charging of new energy vehicles: This is because the components converting current and voltage generate heat, triggering the cooling fan of the electronic control system, which is a normal phenomenon. If the ambient temperature is relatively low and the heat dissipation is good, the fan may not start or operate at a low speed. If the temperature exceeds 40 degrees, the fan will start running. If the temperature exceeds 50 degrees, the fan will run at full speed, and the owner will hear a very noticeable noise. If the quality of the fan is poor, the noise during operation will also be louder. Long-term use of new energy vehicles can lead to dust accumulation in the charging system, which can also produce loud noises. During charging, new energy vehicles generate static electricity, which attracts dust from the environment to the charging system, impairing heat dissipation. As a result, the temperature rises immediately when the owner plugs in the charging gun, and the fan runs at maximum speed all the time. In this case, the dust can be cleaned, and the fan can be lubricated. If necessary, a better-quality fan can be replaced to reduce noise."
I've been driving a CVT car for several years, and it feels very smooth during daily commutes with almost no jerking during acceleration from a standstill, making the driving experience quite comfortable. However, when climbing hills or during sudden braking, there's occasionally a slight hesitation, especially in slow-moving traffic jams. I've noticed that some CVT models simulate shift points to add a bit of sportiness and prevent monotony. Regularly checking the transmission fluid and maintaining the chain can reduce such issues—don't wait until the fluid deteriorates. Driving habits also matter; stomping on the accelerator may increase unnecessary jerking. Overall, CVTs are designed for smoothness and are much more fluid than manual or traditional automatic transmissions, so there's no need to worry too much. If frequent significant jerking occurs, it's best to visit a shop to check for worn parts or software issues.
