I took my Model X in for service in Portland, OR for the AC that wasn't working consistently. When I retrieved my car, it appears that the technician blew something out of the vents and I had black crap all over my white seats. I am used to Lexus and Porsche service where paper is put over the seats and the floor mat so that the service techs do not dirty your car and give it back to you in the same condition or cleaner. I was appalled that my car was left for me to retrieve with dirty seats. I have had service twice and they have screwed up both times. Anyone else have this issue?
