Hello. I don't own the ct200h yet. I'm still driving a prius, but both cars are the same in most features.

I think there is nothing wrong with your car. 95ºF = 34ºC ...pretty hot.

Driving into the city makes the car (and its battery) achieve higher temps than driving in a highway.

So your battery reached temps over 40ºC for sure.

The fan you heard has 1 to 6 different speed. Positions 1 and 2 you'll not hear. Position 3 you can hear if the car interior is quiet. The rest of positions make a very noticeable noise.

A last AND VERY IMPORTANT THING: NEVER NEVER NEVER cover the grill in the back seat. Don't let anybody sit nearby or put clothes on it.

Some prius taxicab are experiencing battery failures here in Spain because the fan is full of dust, locks, fluff... and the battery cooling failed. This only happened to taxi cars because they drive a lot of miles with people sat in the back.
