I've had two Brothers, cheap ones from Walmart and Costco, and both have developed the problem of not catching every stitch, causing skipped stitches. One lasted a couple of years before doing that, the other only a short time. Can't figure out what causes it, but it does it on thicker spots, like over seams, or sewing on the binding to begin with, then the one progressed to not catching most of the stitches even on piecing.
