Steering Noise problems of the 2007 Kia Motor Rondo

On 5-9-2012, it was raining heavily. My Rondo, which drove fine the day before and the day after, started making a loud screeching noise and the steering became very "tight" feeling. I pulled off road into a parking lot, and when I did experienced total loss of steering control. I came very close to crashing into the parked car beside me as a result. I waited a few minutes, restarted the car. Pulling out of the parking space, my vehicle brakes engaged suddenly without notice, and my son and I were grabbed by our seat belts as our bodies were thrown forward so hard. I was blocking traffic so I restarted the car, and it drove ok on a straight road, but when I turned, again lost steering. When I say loss of power steering, I mean with all my might I couldn't get the car to go where I wanted. The rain stopped and I had no further problems until yesterday, 6-13-12, when it had been raining again. This time, pulling onto a busy road, moving quickly due to the approaching traffic, and again lost all ability to steer. Fortunately I was able to slam on my brakes and go in reverse to get out of the path of oncoming traffic, but had the circumstances been different, my young children and I could have suffered a catastrophe. Nhtsa had two similar reports with the 2007 Rondo: internal sequence number #736xxx dated 8-23-09 and #749xxx dated 12/2/2009. I hope NHTSA and/or kia addresses this problem before someone is injured or killed.
