I dont have a sun roof but i have noticed a rattle noise comming from the back or under the car im going to take it into the dealer next monday it is really starting to bother me anybody else have or had this problem.It is worse on rough roads as expected.I hope the dealer does not tell me they will look at it when i bring it in for the annuall inspection.I really dont like the annuall and semi annuall inspections they are doing now in CANADA at our dealers are they doing the same in the U.S ?
