I own a 2021 Telluride SX. About a week ago, I got off of a phone call using Bluetooth through the vehicle. After the call ended, everything with the entertainment system froze. Volume would not adjust, radio station wouldn’t change, screen was frozen, and climate controls could not be adjusted. I used a pen and hit the small reset button next to the volume dial and everything restarted and worked great. Then yesterday, I went out to the car to get breakfast and it was as if the battery was dead. Doors would not unlock and no lights came on. I managed to get the door unlocked with the key, got in, and sure enough, the battery was dead. I pulled my other vehicle in front of it and was going to jump it. I went to open the door of my telluride to pop the hood, and the alarm went off. I got in the car, and the screen came on, so I put my foot on the brake and the car started just fine. As if nothing ever happened. The car worked perfect the rest of the day. Today, I ran a few errands, everything worked fine. I went out about an hour ago, and I am having the same issue. Car is acting like a dead battery. Except this time it is not fixing itself, it is still acting dead. I haven’t taken the battery out this evening to have it tested because all of the stores are closed. My best guess is some type of issue with the auto-electric shut off switch, but these tellurides are so new that not many people have posted about their problems. Any thoughts would be appreciated!
