The trailer hitch (for the 2004 Sienna installed at Toyota dealership) scrapes almost every time we pull in or out of a parking lot (with a medium to small dip), or go over speedbumps etc. It happens intermitently when the only person in the van is the driver, and happens all the time if we have passengers. We cringe at the thought of trying to pull pull a loaded trailer, with the van loaded. It seems to me that the hitch we have should not have been offered as an accessory for this vehicle. We're waiting to see how our dealership plans to rectify this problem.
Does anyone else has a similar problem?
