Engine Clicking And Tapping Noises Problems of Saturn Aura

I was having trouble with my engine light coming on and reduced engine power and traction control off and throwing codes. Mostly 0641, 0107, 0106 and 1682. I have a code reader and was always able to clear them. I they came back right away I would disconnect the negative cable and that would seem to work. Sometimes I would drive for a couple weeks to a month or two with no problems. Then on Aug. 21, 2017 the engine light came on again and I had a hard time getting it started again. When I did it was running rough. So I drove it to my local dealer, they reset the codes and updated the ecm. The next night I was driving, car was running smooth, no problems. I pulled into a parking lot and the engine light and reduced power and traction off warning came on. It was running rough and stalled. I tried to restart it and the was a fairly loud noise from under the hood. There were codes set 1682, 0452, 0641, and 0107. I tried to clear them with my code reader but they wouldn't clear. I un did the negative cable and that didn't work. I tried to restart the car and all I got was a mild clicking sound I noticed a burning smell from under the hood, so I thought the ecm burnt up. Since I was unable to get it started I called a tow truck and had it towed back to the dealer. The next day the when I contacted the dealer they asked me if I wanted to have the repairs needed from the previous day done. None of the noted repairs had anything to do withe the car dying. I told them to just figure out why the car will not start. While they were working on it I called gm owner assistance because at this point I had some feelings of mistrust. The dealer called me after 3 hours and told me they were not going to charge me the service fee and my engine was seized. I was flabbergasted. I asked them how could the engine just seize up with no warning. I.

While passing another car to merge onto an off ramp, I accelerated and then let up on the gas pedal as I exited. Immediately the engine started making a loud ticking noise which continued as I drove home on surfaces streets. Upon starting the car the next day I heard a light knocking noise. I drove to the chevy dealer and the knock got louder. They advised tearing the engine down for $1,000 to determine the issue. They said there was metal in the oil. I believe my issues are the same as many 3. 6ltr vvt engine owners, the timing chains and supports for them. The noise is persistent and varies in tone. I had barely 50,000 miles on it and have kept the oil changes regular, I even had mobile 1 synthetic put in its last oil change. I am extremely frustrated as this was my first american made new car purchase and there were only eight months after it was paid off when this failure occured. I am a usaf vet and retired from a city job of 30 years. After spending $32,000 on this car, I expected so much more.
