Engine Cooling System problems of the 2004 Volkswagen New Beetle

To whom it may concern, my 16 year old daughter drives a 2004 Volkswagen beetle with automatic transmission that has been very well maintained and only has about 47,000 actual miles. Recently she has been having some very scary experiences with the vehicle and we are highly concerened for her safety. When the vehicle reaches 55 miles per hour on the freeway, it starts to automacially slow down while her foot is on the excelerator and then as she continues to keep her foot on the gas, it all the sudden violently jerks into gear and starts to excelerate again. She was on flat teranine and was not going up a hill when this happens. She said the experience today left her terrified to drive the vehicle!! also, she placed the vehicle in reverse to back out of the driveway, and the breaks and steering wheel both locked. She couldn't steer or stop the car without using the emergency brake. I asked her if she is sure the care was not in neutral and she said it was absolutely 100% in the reverse position. Also she stated the brakes are making a hissing sound like when you let air out of tires, but not all the time and her brakes seem fine. I would like to know about any recalls this vehicle has had and also would like to know what you are willing to do to rectify this issue. I do not feel comfortable that this vehicle is safe for her to be driving at the moment and she has stated that when the issue happens, it feels like her and the car jerk forward with a very violent excessive force. I would like corrospondance started in case in case anything happens to my daughter while operating this vehicle. Your prompt response is appreciated. Traci rivera 702-218-0422 tracir3966@yahoo. Com.
