The conjecture is a known problem for Kia Sorento 2.
The easiest way to remove the bubble is to contact an authorized dealer who has to fix the warranty issue. Dealer is familiar with the problem. However, you can try to solve the problem yourself.
Inside the unit is a large bag of silica gel (as in shoes-absorbing the moisture of the ball), which drained the space inside the unit-headlights. If there is excessive humidity, the silicon can absorb moisture in excess quantity and stop working.
To resume the function of the Silicel, it will be necessary to drain the headlamp with a hairdryer.
There are also several reasons for the conjecture, as well as the ways to deal with them.
The following are withdrawn from the rear of the unit:
-A moisture pipe is worth checking whether it is bogged down by dirt;
-an emergency cell. It is in a muted state, but if necessary, it can be used to provide additional ventilation. To do this, you cut down the tip and reconnect the rubber tube to remove the moisture.
