I did installed foglights which are hotwired, to meet the DRL regulation. In my other car, I just went to CT with switch at auto mode, and they passed the car, as DRL works at auto position. But this depends on the inspector.
Warranty is honoured by both lexus and toyota dealers, so I think I have upper hand.
We bought 4 cars in our family. 2 Siennas, and 2 Camrys (XLE + TCH) all new and no issues at border.
