We just bought a 2016 SE and are having the same problem. According to our dealer, who has tried to fix this twice, they were just notified by Supra that this is known issue for which there is an update. We just dropped our boat off yesterday to have this done. I hope it fixes it because this is quite the pain in the ass. With ours, almost none of the switches work, including the ballast, and our underwater lights never work when they are under water. Also the vision screen gets very hot. After seeing this problem, it concerns me that if vision goes out one cannot empty ballast (and get the boat out of the water). Therefore, I think it is important to learn how to bypass the system in order to empty ballast. When we purchased the Supra, we were under the impression that the switches were a good redundancy feature, but they are obviously not. I am surprised the Supra people don't monitor this site and have not addressed your concern. Good luck to both of us!
