I have recently noticed that there are no LTE or WiFi signals in the garage after waking up the car. I made of appointment for this. I had chat with them and a person from Tesla also came in my house. They said it's normal. Normally, I don't get software update information on my phone. I always need to do manually on the monitor. Luckily, I got latest software update notification on my phone during the chat. I couldn't show him the problem at that time when he was there. I'm seeing no signals after he left. Is it normal for everybody's tesla model 3?
