I have a 19 tahoe with the 6.2L with 23K miles on it. Taking a road trip with my family and suddenly the media screen began displaying the traffic behind my as I was cruising down the highway. The radio still functioned via the steering wheel controls but the screen was just a display of the backup camera. When the vehicle was shut off the display returned to normal. As soon as I started my tahoe the display would again show the backup camera view. I also found that my reverse lights were on whenever I started the tahoe. We'll approximately 800 miles later on my family road trip the display began blinking and I cheered as my screen returned to the media screen it was supposed to. A moment later my 7 year old daughter yells daddy there is smoke! From my rear view mirror I could see smoke coming from the rear hatch. I pulled over evacuated my family and opened the rear hatch. There was a bit more of smoke that came from the rear hatch door. I waited several mins and reloaded my family with no other problems 400 miles later. Now I have no reverse lights and no backup camera but my media screen works fine. I'm in FL enjoying vacation with my family 2/19/22. I depart back to Buffalo NY in about a week. I have a warrantee from my dealer where I bought my tahoe. Any ideas what could have caused this? Thanks fellas
