Thanks for your thoughts… a few more details. The dealer has actually had the car in on 4 separate occasions and other than replacing the battery has not been able to find anything. This last time, they had it for a week, during which they talked to Toyota engineers from the US and Japan. They even had the car “camp out” in my garage overnight and came back the following day to be certain that there is no mysterious electrical interference in the vicinity. They have never been able to measure more that a 22 milliamp draw, just enough to run the clock, presets, etc. At this point, they have given up… and I guess I’m on my own until it happens again. This our 8th new Toyota vehicle over the last 12 years and the first I have had any problems with. It has been a rude awakening to learn quickly the dealer is willing to write off a significant problem. Live and learn.
