I have a 2015 LS460 with 25K miles. I just went to start it and there is no power what so ever. No interior lights, no start button lights, no nothing. There were no signs of a weak battery or any other indications that there was a problem. The battery is one year old, and I'm sure it's fine. It seems more like a fuse or computer module that has blown. Does anyone have an idea of what it could be?

 

 

 

Thanks for your input!!!

Just got it jumped this morning and it seems fine at this point, so obviously the battery was dead. Just so strange as there was zero indication that the battery was weak. When power was restored, there were no signs of interior lights being left on. I'm thinking the headlights might not have done the "auto" shut off as designed. I believe it has been mentioned before in this forum, that there are door sensors that detect if the door has been close all the way. If one of those is acting up, the headlights won't turn off. Hopefully this wont be a problem going forward.
