Lol maybe! If you would have noticed before you drove it off the lot they certainly would have replaced it.
I think it really depends on how you act when you go back to the dealer to inquire about it.
If you ***** they will most definitely laugh at you after they send you on your way.
If you are sincere and genuinely worried about it to the point of shedding a tear they may feel bad for you and replace it... at the price of your dignity of course
If you are technically inclined and explain a failure in the composition of materials in that specific batch of parts you may baffle them into replacing it.
Or just wait a couple more years and get a replacement off of a total if it bugs you that much.
Unfortunately, if you drive it, it is like getting that first ding or scratch, it is inevitable, a fact that you need to accept.
It's the fact that it cracked on its own. I would understand if I did it on my own. Toyota quality is not the way they used to be. I mean I bought it new and inspect interior and exterior before I took delivery. I only I have 5050 miles on the thing.
