Transmission Fluid Leaking problems of the 2003 Hyundai Sonata

I have a 2003 Sonata bought new in July 2003, now has 11000 miles. 3 weeks ago texaco discovered a leak around the rt. Cv joint. I took it to key Hyundai who said they fixed it. It was still leaking as of yesterday. Yesterday I was driving home from work when I heard a rattle from the rear. My engine started ticking. Suddenly the car shot forward and sounded like something fell out from the back. I was about 100 ft from my driveway (thank goodness this did not happen on the interstate) so I pulled in with a trail of red fluid following me. My driveway is now covered with this fluid. The key Hyundai of jacksonville had someone bring me a loaner car and said they'd clean up the spill. I had the car towed to them. No word yet. I travel the interstate before dawn daily and home again sometimes very late. I can't imagine what would have happened if this occured during those times. I will never trust this car again and refuse to drive it again. It scares me. I want my money back.
