My 2018 Chevy Traverse Radio Screen Is Showing a Black screen come's on only when I Go in reverse The Sound Still works just no display

I have no communication to starter when I turn key

When my traverse warms up. It starts sounding likae a tractor while heating up

My radio, turn signals sound( click,click), backup sound (beeb,beeb,beeb) don't work most of the time like 99% of the time, and ones in a blue everything just start working from nowhere while im driving, or sometimes when i turn the car on, and i have checked all the fuse and everything is good, the mechanic on the dealer said it is the fuse box, and i already changed and still doing the same, and now i got 2 good fuse box that works, the one inside the hood passenger side, and the one inside the car on the passenger side too, all the fuses are good and the fuse box are good too

The chevrolet trasverse is emitting white smoke from the tailpipe. You can be driving it, then it will give you a response the the engine power is low, then it will start emitting white smoke from the tailpipe, after a while it will stop smoking

When I turn the key doesn't crank

Driver side marker light out on hatched changed bulb no help looking for fuse

Car stalls after idling running for a few minutes. Issue with service stabilitrak, traction disabled.
