Check Engine Light On problems of the 2016 Chevrolet Colorado

The check engine light came on it popped up engine power reduced wouldn't go over 35 miles and hr on the interstate is not a good thing. I pulled over turned car off. Turned key back on started it was fine. A couple weeks later pulling out in traffic check engine. Light. Comes on and loses power again almost get hit. Go to parts. Store to plug machine for diagnosis. First it said unknown. So we do it again pa201 00 code. Computer said co2 sensor. I was told a TSB bulletin came in for this software update but nobody wants to talk about it they just want to fix it then charge. U for it. But. I think it should be covered software issues shouldn't be absorbed at customers exspense. My truck is a turbo diesel its hard to find parts for it at part store and diagnostic machine just getting in oil filters. Anyway in response of software it should be covered by someone else besides me. Before it loses power and vet's me killed or I. A wreck need issue resolved.

Driving at about 60 miles a hour and lost all power engine was running but going no were all light were lite on dash like you turn key on before starting thank god no one was coming the other way or the car behind me would have hit me. He was a good driver. Shut it off and restarted it then it would run with all light on dash even brake light and anti skid light and it said on infro. Running at reduced speed. Drove to my home a slow speed it let me. Shut it down let it sit a few min. Restarted it still the same. Shut it down for about ten mim. Restarted it. Seem to run ok but check engine light is till on now I afraid the will just reset it and say it is ok. And next time I won't be so lucky. It has 5500 miles on it. I did see my life before my eyes hopping it dose not happen to others. Taking dealer tomorrow it happen at about 5pm 3/24/2016.
