I have had my V6 for about 5 months now. I have never used it much, until lately. I notice when driving at slow speeds there is a rattle, that sounds to be under the rear seats. It sounds like something is loose. But I can't track it down. Also when turning sharp there is a snapping sound coming from the rear. I had it to the dealer, but as usual they say is normal and run it. Does anyone with a V6, hear this rattle and snapping? If so what did you find to be the culprit? Thanks.
