I have a 2003 Rx300 that has a rattle in the rear cargo area. I have taken it to the dealer and they say it performs as new. I still have the rattle, that occurs while driving into a driveway with a small raised apron. It almost sounds like a shock topping out type sound. It does not do it over larger bumps. The dealer assures me there is nothing wrong yet I DO have the rattle. I have checked the spare tire area and jack etc. nothing appears loose. Any suggestions? It is annoying and sounds like a cheap car.
