Dash rattles

Just bought a certified 2002 Sequoia with 33,600 miles on it. We have had for about 3 weeks and noticed that when going over small bumps something in the dash vibrates or rattles a little bit. Does anyone know if the dealer would correct this or if anything at all could be done. I have a Nissan and a dodge with over 140,000 miles on them and never had this problem. Just thought spending this kind of money on a vehicle with low miles I shouldn't have this problem.

any input would be helpful....many thanks

Still under factory warranty so Ride with someone at your dealer and show them the noise they will take care of u
