Wow...will this issue EVER be put to bed???
I'm about 300 miles shy of 16K on my car (got it the second week of January) and I've driven it in just about every condition out there including Arizona and Nevada deserts and 100+ degree weather and at numerous autocross events; I take care of my cars but I don't baby them - I've yet to have a problem.
I'm not trying to discount legitimate concerns but really, if you track your car or if you are just worried about it then get a cooler and get on with life and enjoy your
car!
