2001 Odyssey EX. When accelerating and/or turning from a standstill, a "thunk" noise comes from somewhere in the front like someone was hitting the underside of the car with a rubber mallet. The dealer readjusted/tightened things a couple of times, the noise woud abide for a few days and return. Finally, the whole front sub-assembly was replaced. The noise may be temperature sensitive since it started in May and seemed to stop with the new sub-assembly in Oct though I heard it again in Nov when the temp got up over 70. Anybody else experience this weird problem? Honda cannot figure out what exactly is causing the noise.
