I have a 2009 Nissan Pathfinder. I noticed that the center console (where the AC, radio are) is running hot under the carpet by my legs (probably about ankle high). I can feel the heat coming off it with my legs. Is this normal and I’ve just never noticed it before?
Have you had your exhaust system checked, possibly you have lost a heat shield.
edit: just realized that your engine is mounted longitudinally so this is where your transmission is. Do you have an automatic transmission, and if so, does your owners manual call for a transmission service at specific intervals? If it does, has it been done? If it does not call for servicing, I’d still recommend that someone at least look at the ATF to see if it is breaking down.
If it is breaking down, then maybe one of the cooling lines for the transmission has gotten kinked or something has happened inside the radiator to the heat exchanger for the transmission. Worse case, the heat exchanger has gotten a hole in it and you are getting coolant into the transmission so it is critical to get the ATF checked pretty soon.
