I have my doubts. Can't get any help with service issue. Felt "chatter" and had tires checked. Rears had flat spots and unusual wear pattern. Used app to schedule Service Center - two week wait. Few days before get notice of at home appointment. Send note saying can't be handled at home. Get appointment a week later. Go in explain issue. Wait three hours - car ready, balanced tires. Said thought needed alignment, but left. Immediately noticed still a vibration. Try to get a human? Nah. Tesla service is fully automated. Use app and it offers one appointment, have another meeting at that time. App won't allow search for another time. Accept time. 10 more days. Arrive at Service Center, 50 mile drive btw, only to be told they have no loaners. Tell rep unacceptable, when can I get new appointment. HE CAN'T DO IT!! HAS TO BE CUSTOMER SERVICE AND THEY WILL CALL ME. "WHEN?" I ASK. "I DON'T KNOW. SOON." HE REPLIES. Three days later and nope, no call. Suggestions please.
