I just encountered a similar problem. I have a 2017 LS460, bought in 2021. Only 42K miles. Because of recent medical problems, I had to leave the car parked for like a week. When I tried to start it up…nothing! This happened twice over a period of 3 months. I’m not sure if this is the original battery, and when I asked the dealership service tech, he says they couldn’t find any record of it having been replaced. So, it came down to me just pressuring them to test the battery, and they found one cell in it failed. I know very little about cars, but I do know when I have to be somewhere, I expect my car to help make that happen! I’m due for more downtime. Should I locate that switch?
