This just happened to my mom's 2007 rx350. She didn't know about it, no lights, until she drove home across town and heard a knocking. Oil was empty and dripping from the entire underside. The dealer did 6k worth of repairs. Corporate will cover 50% but after repairs there is still a knock. Now she is screwed and is considering a lawsuit. She has impeccable service records from the dealer, they never suggested that part be replaced during any service. She never got a letter about the part, I suppose since she bought it third party initially.
Poor mom, we convinced her to buy Lexus due to the excellent build quality. Engine only had 100k and now probably needs to be replaced.
