My new Sail is 1.2EMT, and I ran1800km. In the last two days, I suddenly found a slight jitter when starting and braking. What is the reason?

This situation may be caused by improper running-in of the clutch. It is recommended that you check or replace the clutch pressure plate when you go to the 4S shop for maintenance. In addition, when driving, try to avoid stepping on the clutch for a long time, or let the vehicle be in the semi-linkage state of clutch and throttle, that is, simply shift gears as much as possible, which can reduce the occurrence of clutch problems.
