Radio/tape Cd Player problems of the 2017 Chevrolet Colorado

Truck only has 30,000 miles and always keep up on maintenance through chevy dealership. When driving home on highway truck shut off on busy highway with construction going on and no where to turn off when shut off. Radio was playing but lost totol power. . . No problems with truck prior to this and full tank of gas. . When was able to stop and put in park started up with no additional problems. Although as lightly pushing pedal to continue it peeled out as if the pedal was pushed all the way down. Was going 60mph when engine died and all lights including head lights shut down. . . Very very scary situation. . .

When automatic transmission downshifts into 1st gear coming to a stop, it lunges forward. If when nosing into a parking space with any kind of pole or vehicle directly in front of my truck, not leaving enough space my truck would hit whatever. When driving slowly with my 8 speed automatic transmission sometimes it rattles as if I am on a rumble strip and sometimes it just clunks or thuds. This and other shift issues make me even more hyper vigilant when driving. 6 months after I purchased my brand new 2017 Colorado, during a spell of negative degree weather I lost the following: my cruise control, traction control, four-wheel drive; my engine light came, oil light all lights came on and my radio stopped working. I was told by my chevy dealer that this was normal in cold weather. Next, I was informed it must be because I washed my vehicle the day before. This went on for a few months, with me showing them videos and them telling me they could not duplicate the issue. October of 2018 they replaced my radio because evidently the radio had a bulletin that showed all of the things I had complained about. I want to say this happened in excess of 10 or more times. Driving to my mothers one evening in the dark my dash lights were not dimming correctly and then went out. As I got to a four way intersection with cars coming they came on so brightly I almost got in an accident which prompted me to make an appointment and I wasn't willing to hear silly excuses.
