NHTSA Complaint #11649789 — 2018 HONDA ODYSSEY

During rain and snow storms I will get warning lights that the power tailgate isn’t working. Last year when I took it into the dealer they said the tailgate would open and close randomly and there was water in the rear fuse box. I thought I fixed the issue by replacing all the wires from the rear all the way to the front. They fixed my tailgate and did water testing to make sure no water was coming in through the tailgate and all was great. Fast forward to this year and the middle of February we had an all day snow and rain storm and I start having these same warning lights along with a couple others. By the end of the day the tailgate completely stops working. I take it back to the shop that had originally fixed it and water is getting in. Not from the tailgate but through some unknown opening. The fuse board is completely corroded and we have to replace it again. They could not determine where the water is coming in from. I do not want to be driving down the road and have my tailgate randomly open and have items fall on the road causing injury to someone. Nor do I want to have to pay $1000 to fix the circuit board every time it rains or snows. I live in Utah it happens frequently.
