Well, I have a complaint about the Odyssey. Had to remove our carseats to fit in some lumber this weekend. Turns out the seat belt guide on the base of our infant carrier actually made a lengthwise gouge through the seatbelt. None of the previous cars we've put this seat in had this problem. I suspect the stitching/construction is to blame, but it could have been a different force/angle in the Odyssey that caused it.
I doubt it has made the belt unsafe, but I will probably have to have it replaced eventually. I wonder if I can get it done as a warranty repair somehow.
