Reporter: We're talking about a car that was later recalled for major safety issues. After miraculously surviving that accident and those six days in the ravine she and her lawyer now believe gm knew about those problems for years. What's the first moment that you remember?

Reporter: This morning a year and a half after the devastating accident that kept her trapped in her car for six days and resulting in the amputation of both her legs below the knees 45-year-old Kristin Hopkins is speaking out only on "Gma" demanding answers from general motors. What is your message now to gm? Basically why did this happen? I mean, it's -- I think it was something that could have been taken care of. Reporter: A complaint filed Tuesday against the automotive company claims gm's inappropriate quality control and manufacturing practices are to blame for the crash. Hopkins' 2009 chevrolet malibu plummeting 300 feet from this Colorado road. The complaint alleging that the power steering, traction control, electronic stability control and panic braking assist all failed. Gm knew about these problems and knew they put an unsafe car on the road and acted entirely too late to correct that failure. Reporter: Gm has issued safety recalls for the 2009 malibu, but according to the lawsuit, Hopkins received her first recall letter from gm nearly two months after her accident. The second just weeks ago. So you think at this point that the two recalls are connected to the accident. 100%.
