I know, I have been following your issues with your car... not very encouraging. Not including drive unit issues, the first 50K on my car would not equal $4,000 worth or repairs. I can tolerate cosmetic issues, squeeks and rattles, and some basic wear parts. I can't tolerate major repair problems, especially the fix-break-fix-break-repeat kind. This extended warranty is a very hard decision for me... I generally consider them a waste of money. If the car really can't go 50K without over $4K in repairs, then I am in trouble... If my car was seeing the issues that you have been running into, I would probably just take a bath and trade or sell. My car really has been pretty good to me. I dunno, I am still debating it with myself. I have sort of committed myself to be on the non-extended warranty side of the experiment. This whole Model S buying thing has been one big experiment.
As far as light bulbs go, it looks like a PIA to change, but so was my last car (as are most cars these days). But I am not going to pay $1,000 to have someone change a $70 bulb. Time to start learning how to take this car apart...and hopefully put it back together.
