Radio/tape Cd Player problems of the 2011 Chevrolet Traverse

My mechanic said my timing chain is loose & there should be a recall. Also my radio goes real low in a high pitch tone & I can't hear it so that means my turn singnals are low & everything else that makes a sound is very low. Also my window controls are all starting to not work one by one. I only have 89000 miles on my car. My mechanic is telling me I should get rid of my car but I always thought chevy was a good car.

On Friday, July 25, 2014, my 2011 chevy Traverse stalled/shutdown while driving. I pulled out of a local gas station and immediately noticed that there was a noise coming from the engine. Almost simultaneously the car began to stall/shutdown. I pulled over to the shoulder (fortunately there was one). I turned the ac unit and radio off. I started the car without any noise. I drove approximately 1 mile, turned the ac back on and the car stalled/shutdown once again, this time as the car was going approximately 35 mph. To say the least, I was extremely distraught as the car lost power and steering. Fortunately, (for my family and chevy), there were no children in the car and there was no accident. The service manager told me that the problem was related to the ac unit and wants to charge me almost $2,000 to fix! the ac unit was "fixed" back in June 2013 while car was under warranty. It is no longer covered by warranty. My issue is that the car stalled/shut down. A car shutting down at any speed is a clear and present danger. Traveling at 35 mph creates an even more dangerous situation. If the ac unit can stall a vehicle then this has to be an inherent design/production issue. There is no acceptable way that an ac unit can fail and thus cause the vehicle to shut down putting people's lives in danger. Hopefully, my incident report will prevent any future problems like this from occurring, and most importantly, protect people's lives.

Around may 11, 2012, on the ohio turnpike, accelerating to 65 mph, my car began to make a loud repetitive noise under the hood. After a few miles, a battery service light came on. The car began to overheat and become difficult to steer. As I reached a pullover, the power steering failed and everything else quit working (radio, lights, etc. ) I turned the car off and could not turn it back on. When the car was towed, we found the belt was shredded and dragged behind the car. I was told there was a problem with the water pump. The car was about 11 mos old and had about 11,000 miles on it. On June 2, 2013, deja vu. As I left a store and accelerated to 45 mph, my car began to make a loud repetitive noise under the hood. As I accelerated, the noises were louder and faster. I drove about 5 miles to walmart, the noises continued, so I drove home, about 5 miles. In the morning, I drove the car very slowly because I thought the belt was shredding again, and as I drove more slowly, the noise (from the pieces of the belt slapping around the engine) became less and I hoped I could make the belt last until I got to the dealer. The service battery light came on and when I turned left at an intersection near the dealership, the car was very hard to steer and I could barely turn into the dealership. The driver following me said he could see the shredded belt dragging. I learned there had been other cars on which the belt had shredded and that there was a service bulletin to put a lining in to protect the belt from damage, not sure if this had been done on my car I learned there is also a recall related to the water pump. In both cases, I was fortunate not to be in heavy traffic, near trucks, or passing on a country road. This seems very dangerous to me.
