I have all the service records for my GX which I purchased in AUG2016. Prior to my purchase, radiator was replaced by Lexus in JUN2015. And I now have very tiny leak with signs of "pink crusty" on the bottom driver side of the radiator. Do you think I'd have any chance with Lexus replacing this for free even if the service was preformed when the original owner still had the vehicle? I'm certainly going to call them and ask...just wanted to know if anyone has had a similar situation.
