LEXUS IS250 AWD Posted February 8, 2010 Share Posted February 8, 2010 Does anyone notice a rattling sound from under the hood after starting the car? It lasts just about 1 second. Used to happen once in a while, now it's a bit more frequent. Any idea what it could be? Link to comment Share on other sites More sharing options...
tex2670 Posted February 8, 2010 Share Posted February 8, 2010 There's a TSB for it. But the dealer won't do the fix unless they can replicate it. I only get it about 1x every 6 months. Link to comment Share on other sites More sharing options...
