Driver's seat came unattached from the floor mounted slides/brackets that allow for leg length adjustments. car was in motion, travelling approximately 35 mph, and in the center of three lanes of traffic at the time. i pulled over and examined the seat. washers were under the seat, and the seat would move up and down 8-10 inches on the left (door-side) side. seat was still attached to brackets/slides on the right (center-line / gear-lever) side.
A recall was issued on the 2011 mazda 2 models related to a problem with the seat height adjuster mechanism becoming loose. based on the description of the issue, my 2013 mazda 2 is exhibiting the same issue. the seat 'rocks' back and forth, as if it's only partly secured. i contacted mazda and they reiterated that the 2013 model is not currently covered under their recall, however the problem is clearly present on mine. it is mazda's responsibility to ensure that all seat mechanisms are functioning safely and securely. the issue was noticed earlier this year and has subsequently gotten worse.
