Hotter Climate makes my Prius act funny
I have a 2012 Prius and just moved from Northern California to Central
Texas. When I come out to my car now after it has been sitting in 100 degree
heat for a while, when I turn it on the whole engine sounds stressed, and
hums/revs in a way I've never heard before. I do turn up the AC, but that's
not new. The car calms down after about 10 minutes of driving, but I'm
concerned. Makes me feel like my car isn't happy in the heat. What is going
on?
