I live in the Yukon Territoies and bought a 2013 Tundra 4x4 double cab long box in November. I have a problem with moisture dripping out of the headliner and want to know if anyone else is experiencing this problem. There is a 3/4" gap between the headliner and the roof of the truck. Because I live in a very cold and dry climate the moisture from my breath, coffee cups and melted snow on my work boots goes up into my headliner and freezes when it comes in contact with the cold roof. This leaves little drops of frozen water all over my roof and when the weather takes a change to above freezing it starts to melt, has nowhere to go so it comes out through my lights in the overhead console. The first time it happened I got over a cup of water poured onto my lap. Ive been in contact with toyota and they gave me a fix for it which was two small pads they placed inside the headliner. This doesnt change my problem all it does is hold the water and when it gets warm it drips out of the lights instead of pours. I want to know if anyone else is having the problem or has heard of this. As far as I know it only happens in cold climates. I have my AC running all the time and will crack my window when its warm enough to. I have the TSB for the problem and it was for 2007 - 2008 tundras. My 2013 is the first to have the "diaper" put in it and the problem isnt resolved. Any information would be really appreciated as Im at a stalemate with dealing with Toyota. Thanks a lot!
