The front passenger heat seat is automatically turned on whenever car is turned on from phone. This time when driving in the evening there was a burning smell for 1 hour which I thought was from the vents. Then the passenger seat started smoking and the fumes were so bad that I could not breathe. No one was in the passenger seat at that time thank goodness. It created a hole in the seat. Tesla will replace the seat under warranty, but service center is 2 hours away.
