Searched, lots of info, need opinions

Hey guys let me ask you. I just pick up a 2013 on sunday. I noticed that when I turn off the truck after driving it. I can hear a noise which I think is the blower fan slowing down and stoping. Is this what all of you are talking about. It sounds like its rubbing against something just before it stops.


And one other thing. I have been reading on here. Is it normal to have a sometype of vibration on these taco's. I can feel it in the gas pedal when I excelerate like getting onto the freeway with a sound as if they forgot to put in some type of insulation between the passenger compartment driver side transmission area. When I am driving normal speed in 4th/OD its smooth. No vibrations. Just trying to see if these are the characteristics of these trucks. When I hold the steering wheel at 9 and 3 positions no vibrations smooth. If I hold it at 12 slight vibration. Trying not to read into these things. I have owned F150/F250/tundras, all were smooth as glass. Just checking.

Just checking I have a toyota Yaris which does not have these types of sounds and vibrations. I know that I should not compare these two but i thought that maybe there is something wrong with the taco.
