Temperatures inside a closed car in the summer can reach 180F.
That said, we leave multiple cell phones in multiple cars year round,
and have never had problems (We live in Ohio; we get 90 degree
temperature days, but we also get -5F days).
I think a bigger concern with your idea is leaving the charger on all
the time. While I don't think that will hurt the phone, I do think it
will kill the battery prematurely.
