I just wanted to share my service experience living on Kauai because I had no idea how it would go. I didn't buy my car here, I had it shipped from the mainland when I moved here.
My daytime running light went out. No indication from the car, I just noticed it in a reflection .... which I thought was odd. You'd think it would know. Anyways, so I tried calling the Honolulu service center and couldn't get ahold of a person. So I scheduled a service appointment in the app and wrote in the notes "I'm on Kauai, I'm not shipping my car to Oahu."
It took about 5 days for someone to call me and confirm that they saw my note and would be sending a replacement headlight with a mobile technician to my house. They had to order the part which took about two weeks. From the day I called until install it was about 40 days.
Everyone I talked to was super helpful. They called me at least 3 times to keep me updated on the appointment and the status of replacement parts.
Hopefully it's that easy to have someone come out and install the FSD computer.
