What is the situation that there is water under Xuanyi's foot pad?

There is water under the Xuanyi floor mat, which is caused by the leakage of the drain plug at the bottom of the carriage, the leakage of the skylight drain pipe, the leakage of the door, the leakage of the antifreeze in the warm air water tank, and the damage or failure of the air conditioning drain pipe. It is recommended to go to the 4S shop for inspection and maintenance. The water under the car mat can be taken out first, and then the residual water in the car can be cleaned. There are several sealant plugs under the vehicle chassis. Opening the sealing plug can release the accumulated water in the cabin.
