I have an IS300h purchased new August 2015, (approx 8000miles). It has recently come to my attention that the offside headlight does not always dip after being on high beam. The fault is intermittent. I did snag this on the 1 year service but was told by the dealership that there was no fault found. Recently the fault has become more frequent, and I have to dip the lights twice to get the off side to go down. This tends to annoy oncoming traffic. After investigations, and replacing some headlamp parts, and swapping parts L-R, the dealership is now sourcing a new O/S headlight unit to cure the problem. Has anyone else experienced this problem or anything like it.
