Sounds like the BCM. After five years of owning two H2s, I've found the main weakness with dealers is their reluctance to change the BCM which controls a myriad of things, from windows, to seats, to door locks, to instrument cluster, to sunroof, to the automatic lights, to the air suspension & leveling (is so equipped),, to inputs to the TCM and transmission. The only problems I've had with my H2SUT has been the back window would just go down on its own, the automatic lights would stay in the night mode all the time as well as the Nav display and the passenger seat electric heater stopped working. It all seemed unrelated to me and to the dealer on the first visit. The second time they replaced the BCM and voila, everything normal again and no problems since.
