The red neutral light is a common problem and is related to the buttons getting old. Come to a stop and select 4H and the light will go out - at least that's what the dealer told me to do. Then at a stop cycle through the 4X4 buttons. This is a problem that for many people just seems to go away after time. I had this when my H2 was new and they replaced all the 4X4 buttons under warranty and it was fine for 4 years and started doing it again for a few months and then it stopped on its own and I haven't seen the red neutral light in over a year now. I also got a service 4 wheel drive light once on the message panel with the red light on and the dealer told me to come to a stop, select 4H and the message went out and never came on again. My recirc does the same thing as yours does on a random basis.
