our GX470 is 4 mo. old, 2600 miles. About 1-2 seconds after coming to a stop at a light we can feel and hear a "thunk" in the drivetrain- feels like a loose U joint or as if someone tapped you in the rear with their vehicle. Louder/stronger sensation with sudden or firm stops. Service Mgr. described phenomenon accurately, says it happens in his GX and it's normal. We find this strange- neither our LX450 or LX470 had this problem. Anyone else have this? Suggestions? Thanks.
