I would be fine with your repair bills out of warranty too... but mine on the other hand would have exceeded $25-30K if not covered by the warranty... the HV battery alone is ~$22k and the cabin heater is ~$3000 just for the part.I've had two trips to the shop in the 13,000 miles since my 2013 S went out of warranty: a rear window regulator failed and the window wouldn't roll up, the 12v battery failed, one of the TPMS sensors failed, and a few lug nuts were getting out of tolerance and my tire shop wanted new ones before they couldn't get the wrench on anymore. About $900 total in repairs over 9 months, vs. $1400/month to buy a similarly equipped 2017 to restart the warranty. I'll gamble on the occasional repair bill a little longer I think until I'm ready to replace it, hopefully once there's some semblance of value in the FSD option.
Meanwhile my wife's Lexus is going in for $3800 in front end steering and suspension work, so it's not like ICE cars can't rack up the bills out of warranty too.
