I am with you. Tesla is out to prove what Toyota has proven time and again in terms of being a dependable manufacturer. Not to say I've had major problems with the Tesla, but Toyota Care is a huge asset and I'd have no questions about build quality and service options. It's likely by then too that the market will equal out and Tesla may be able to place a larger emphasis on QC. Until then the market has favored Tesla in spite of these issues, so there's no reason to invest resources there.I'm not going to know until that time comes... likely not for another 5yrs or so when my 2017 Prime is up for replacement.
When the time comes to replace a car I have little brand loyalty. it plays a factor, but not a major one. First is requirements. what do I want my car to do? Then I whittle down to 5 or so car models. It's at that point that my perception of the brand comes into play along with the minor price differences.
To be honest, Toyota/Lexus have impressed me the most over the years. Tesla is in the middle. That doesn't mean I won't buy a Tesla again, it just means if my requirements are all met by both a Toyota and a Tesla and all other things are equal, I'd get the Toyota.
I like to keep my cars for 10yrs before getting a new one, so it's hard for me to say. I've only had my Model Y for a year, I may feel differently about Tesla in a few years (for better or worse).
