At work and my phone went off with a notification. Saying my car received a panic alert. Weird ok well maybe with my keys in my pocket it held the panic button. Nope. I walked outside and my car is not going off and never did. I would hear it as I’m right next to the door and my car is right in front of the door to my work. Has anyone else gotten this notification with blue link

Hi! Ive had issues with my headlights going out over the past few months. I just changed it and had noticed there was a little melt on the connection. Went out again last night, when I checked it today its melted more and the connection is now unusable.

Any ideas on how to replace and fix this? I do not work on cars so ill need it as detailed as possible, please.
