LG GR-L206CPQA SxS fridge/freezer faulty?

My 2-year old LG GR-L206CPQA SxS fridge/freezer seems to have a few faults. While back veggie drawer started freezing veggies, then lately plastic cooling coil/container for cold water behind veggie drawer was frozen and split; leaking water. Recently display panel working intermittently (supposed to be 5 lights on each side, left freezer, right fridge), which I used to keep at 3 each side. Now intermittently no lights on right/fridge side and left/freezer side one light showing at 2nd pip and one light on 4th, i.e. not consecutive. Unit sometimes rights itself to 3 consecutive lights each side and sometimes rectified by switching on and off at wall. Also, some time ago loud noise from "something" (perhaps motor, compressor - unsure), which has stopped. Help please? Is it the control panel or is it something making the control panel act wonky?
