IN THE THIRD ROW THERE ARE NO KIND OF HOLDERS PREVENTING THE SEAT BELT BUCKLES FROM GOING UNDER AND BETWEEN THE SEATS WHEN THEY ARE FOLDED DOWN AND UP. THIS HAS RESULTED IN THEM GETTING TRAPPED BETWEEN THE SEATS AND UNDER THE FOLDING MECHANISM AND GETTING CRUSHED TO THE POINT OF BEING UNUSABLE AND UNSAFE. WE ARE CURRENTLY UNABLE TO USE THE BACK SEAT SEATBELTS DUE TO THEM BEING UNABLE TO BE BUCKLED AT ALL. WE DISCOVERED THIS WHILE THE CAR WAS PARKED WHEN WE WENT TO RETRIEVE THE REAR SEAT BELT BUCKLES FOR USE.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2013 Mazda CX-9 verdict →
