2012 Mazda 3: Rocking Seat
June 13, 2012
Seems our longterm 2012 Mazda 3 has a screw (okay, a bolt) loose. The bottom part of the driver's seat will pop up and down a couple of mm if you lean into the seatback, and the associated play is somewhere between the seat bottom and the seat slider/track.
Seems earlier Mazda 3s and other models exhibit this tendency, according to this TSB. Ours is a 2012 model but it's possible it employs the same seat and track design as those models. Should be an easy fix. Therefore I'll let someone else do it. Say, the dealer at the next service.
