Mark S in 04 - 09 Lexus RX330 / RX350 / RX400h Posted June 26, 2019 2009 RX 350 155k My RX occasionally makes a rattling sound for a second or two when you first start it. Once running, very quiet, and runs great. Could this be a dry Rod bearing, because it is in the morning, or something with the timing chain?
