Radio/tape Cd Player problems of the 2013 Chevrolet Cruze

The chevy eco Cruze has been giving me problems from the start. I was driving with the ac on and came to a signal light when the ac shuts of & comes back on. Also at the signal light I thaught I had gotten a tap from the back from another vehicle because the car jerked. Turned out no car behind me but car still jerks forward with foot all the way down on brake pedal. Next if I'm driving and slow down to make, let's say a left hand turn once I make the turn the car is sluggish as if it has trouble picking up speed. Happens all the time from a stopped position or if I slow down it takes for ever to pick up momentum. Making it scarey to merge or just be on the road. Also if I turn the radio up the lights will die or fade so I've replaced the alternator but it still does it. Ive checked connections wires you name it.

While driving the lights in the radio began to flash on and off and radio would also come on and off, the windows became stuck while trying to roll them up, lights would go on and off as well.

Coming to stop light doing only 15 mph from where I was coming from and all electrical went down. The radio was still on but couldn't : turn up/down music, use any controls on steering wheel, the infotainment screen was black. Had to turn the car off at a stop light and it didn't want to start until I did it twice. After that it was fine and hasn't done it since- but now I see others are having same issues. Also, notice the lights inside do sometimes get brighter then duller on their own- everything including the dashboard and infotainment center. Car also does have an odor with the heat on.

The cars radio and other electrical components (ex. On-star, phone chargers, usb products) will turn on and off at random. It occurs randomly and intermittently. This has happened a number of occasions roughly 15-20 times over a couple of months. It mainly happens at a red light and then will turn back on once I accelerate. This has happened on a highway going 60-70mph and the every light on the dashboard went on and on the display screen it stated stablitrax is off. Immediately pressed my onstar button and asked them to run diagnosis and the whole conversation was going in and out of being able to hear them. My radio was going on and off the entire time when the radio was on I could hear when it was off and all power was off. We did loss connection to onstar and I repressed the button. I have had them run their "diagnosis" multiple times when this happens and they never have anything come up wrong. They advised me to tale the dealer. I have been to the dealer where they advised me that unless it was happening at that time it would pretty much be impossible to figure out the problem. I have heard some clicking or switching sounds come from under the hood while I have been driving occasionally not sure if and my engine temp always runs cold not sure if either of those relate. It would be nice to feel safe in my new car and it would be nice to be paying for onstar and not have a doubt they would be reachable if this causes a bigger problem! be safe fellow chevy Cruze drivers!.
