Vehicle was parked in garage. Metal support bar in the back upper portion of driver seat broke. Seat was being used as ordinary and snapped when I went to retrieve item from back seat by reach over center console and to back seat to grab purse. I weight 135 pounds and am small person. No extraordinary pressure or weight shift. I have found numerous complaints online from people seeking solutions on how to repair this extremely common issue as to lead me to believe these seats are defective and dangerous . Refuse to drive truck as not certain that safety belt will be of any use in an accident as seat flops around now and has awkward tilt back to one side on the console side and lays back to far to clearly see over dash even when fully posturing erect.
