I left my car at the airport for four days. When we landed, I went to turn on the heated seats and the app wouldn’t connect with the car. The car kept looking hollow or flashing, but not showing up. When I got to my car, the app still wasn’t working, luckily, I had my key and was able to get home.the mapping didn’t work very well on the way home nor did the radio. Once I got home and plugged the car into the charger, everything was fine. Any ideas?
