My 2018 model 3 72k miles in the service center now, issue started with the cameras no longer showing on screen, which obviously disables multiple systems. The initial estimate was fsd computer failure (2k). When I dropped it off Saturday, they said they had to troubleshoot it and the expect it back by Wednesday which I thought was strange since the original hw3 replacement only took 1.5 hours in my driveway. Anyways, get a message Tuesday that they confirmed that the fsd computer needed to be replaced. Wednesday afternoon I asked for an update as that was the original day for completion, SC responded that they were "having issues programming the computer." Which is also strange to me. Has anyone else had an issue with fsd computer failure and what has been the experience with tesla communications on repairs in general?
