Seat belt buckle in 2nd row is designed so that it is forward of seat crack and cannot move to a completely upright position. This causes major movement/isecure belting of a child convertible booster seat, especially front-to-back movement. This movement occurs even with the tether anchor strap installed. We complained to Mazda and wanted the seat belt buckles replaced (to match the redesigned and workable seat belts in the 2001 models) or the entire seat replaced with the 2001 seats. So far, we have had little success getting any feedback from Mazda. Additionally, once we began pursuing this weith Mazda, threee different people within the company have informed us that no child seats of any kind are to be used in the 2nd row of the 2000 Mpvs. However, they went ahead and installed a tether anchor mounting kit behind the second row (as they have done for many other customers too). Doesn't that imply that you could use child seats in the second row? if you truly cannot install child seats in the 2nd row of the 2000 Mpvs, then an entire year's worth of Mpvs were sold under false pretenses as most minivan owners have small children and belt their car seats in the second row. Also, the 2000 MPV user manual illustrates putting child seats int he 2nd row -- contradicting what we have been told repeatedly by Mazda. We are very concerned that a major vehicle manufacturer can sell minivans which apparently are not designed for safe use of car seats in the 2nd row. Probably many uninformed MPV owners currently have their child seats in the 2nd row. We had hoped that Mazda would take a proactive stance on this issue, but what we have mostly heard is, "child seats must be installed in the 3rd row only and cannot be installed in the 2nd row." Please investigate how Mazda is able to sell these vehicles without first informing the consumer of this issue, and investigate Mazda's unwillingness to investigate fixing this issue.
