You'd be better off to start your own thread rather than piggybacking on this one. You might call it "Rattling sound on acceleration 2016 LS". You will likely get more help and advice that way.My 2016 LS with 500 miles is now making a metallic rattling sound sometimes when I accelerate. I took it to the dealer for a recall fix on the battery and mentioned it to a service advisor. He told me everything was fine because it passed a multi-point inspection. I'm trying to catch the sound on video but no luck just yet. Any advice?
