Hey all, was doing a Google search that brought me here. I have a 2020 Silverado 1500 high country. I went to go start it and was completely dead. Now before this happened I noticed that the parking sensors switch was disabled. Every time I tried to enable it would enable and quickly disable. Also noticed when I start the truck with the remote start, the headunit would be black when I get inside the vehicle and hit push to start. So I would literally have to turn the truck off then on for it to come back up. Just about 2 days later the vehicle was dead. I jumped everything was back to normal. I called the dealership to notify them that this was happening and had them check it out. Dealership said no issues with the battery and etc. It was about a week, all over again except the parking sensors were working fine. So I said maybe I left something on which is impossible but let the second time go but closely monitored to see if anything was out of the norm. Finally, about a week or two go by, and the headunit issue starts again. Black screen after I go into the vehicle after it was remote started and hit the push to start button to leave. I knew it right away that it was going to once again drain the battery. New thing I noticed was that the wifi hotspot, after the truck was off for HOURS was still on. I noticed this because my phone was connected to it. This was at least 16 hours where the truck was not touched. I planned on the next day for it to be dead, and there it was completely drained. I made another appointment and I will update you guys on what I find. What I would recommend is see if your vehicle has a hotspot and if it does see if it stays on for hours after your vehicle has been turned off. I use my hotspot but there is a way to turn it off. Whether that works or not I'm not sure. I will further troubleshoot though because the dealership is probably going to give me the run around again. Good luck
