I HAD MY CAR IN PARK WHEN THE CAR PROCEEDED TO GO BACK BY ITSELF WITH MY CHILD IN IT.I RAN AFTER THE CAR AND THE CAR DRAGGED AND SCRAPED ME AND SMASHED MY RIGHT LEG.IT STOP WHEN IT HIT MY NEIGHBOORS FENCE. IF IT WEREN'T FOR THE FENCE IT WOULD HAVE RAN ME OVER.I CONTECTED THE MANUFAUTURE AND THEY SEND SOME ONE OUT TO INVESTICATE AND PROCEDED TO TELL MY THAT THIER WS NOTHING I COULD DO.I CONTACTED SEVERAL ATTORNEYS AND THEY SAID THEY COULDN'T HELP ME. I FEEL THAT THE CAR IS UNSAFE AND I HAVE THREE CHILDREN AND CAN NOT AFFORD TO PURCHASE A NEW CAR TO KEEP MY CHILDREN SAFE. I HOPE THAT YOU CAN PLEASE HELP.
