Engine Belts And Pulleys problems of the 2006 Buick Rendezvous

At any given speed the "reduced engine power" light comes on and the car comes to a complete stop. There is no power steering, etc. It's extremely dangerous because of being able to get the car off the road. I am reduced to driving on the service road and still do not feel safe. Interstate is out of the question. After reading many reviews regarding repairs, I am not inclined to spend a tremendous amount of money for repairing a car that obviously no one can repair. I believe the manufacturer should be responsible for recalling this car. It's extremely dangerous and I cannot believe there have been no fatalities due to the fact at any given time the vehicle loses power. I noticed there was a recall on seat belts, believe me that is minor compared to the terror of being on an interstate or secondary road with grandchildren and the engine on your car completely stops. Please intervene on behalf of myself and countless others. Obviously this vehicle is not safe for anyone to drive. I will be parking mine because from what I have read it appears this problem is a factory one and the mechanics cannot repair these cars. Thank you for your time and consideration and hopefully with enough input the manufacturer will begin recalling the Rendezvous and make it a safe vehicle. By the way, on one occasion I started the car, and while still in our garage, "reduced engine power" light came on. Thankful I was still in my garage that day. Shortly after trying a few times, the car started, then on the way to pick up grandchildren, died again on a two-lane road and had to find a tiny area to pull off. I am not in a position to buy another car. I haven't been able to read where anyone has actually had their car repaired. I bought this car especially for driving my 4 grandchildren. I'm 72 and now unable to have that pleasure due to the danger of stopping.
