G37 get's really hot inside even with a/c on full blast

[Nocturnal]

I have an 09 G37 sedan. It has roughly 2000 miles on it. I noticed sometimes after I've driven the car for an extended period of time, the area where the gas pedal is, and directly next to it where the center console is, gets really hot. This leads to my feet becoming hot, especially when I'm wearing flip flops.

Has anyone else experienced this and or found a fix? I did a search on Google and I did find someone else who had the same problem. He didn't appear to have found a solution. I'll be contacting the service department soon to see if I can have them take a look at it.

Thanks for looking.

I had this problem on my I30 and also on the G.

I read something about necessary venting, but I think it's a poorly designed vent system if that's the case.

Just curious but where'd you read about this?

Can't find the original, but search for "Hot air on feet car" or some variation. You'll see that the problem isn't isolated to the Nissan family.

Have you tried to use the floor vents with the AC on?

I have, on high and it still makes no real big difference.

I did a search on what sentient said to search on and sure enough I've found sevral others, especially luxury car owners from the likes of Lexus, BMW, etc. all with the "auto" mode a/c and it seems to be a recurring issue. Apparently it's a feature. The thing is, I normally set my a/c to always on, no auto necessary yet the heat still builds up near the gas pedal.

Spontaneous human combustion seems to always start at the feet. Make sure you put the system in auto to keep that area as cool as possible.

Based on what I've read, I think the stuck heater core valve is a likely culprit followed by the mixer valve.

What makes me lean towards the heater core valve is the fact that the heater core should be inactive when the heater is not in use. So if the mixer valve was malfunctioning, wouldn't it give you ambient air, not hot air?

I live in Hawaii so using the heat is really not an issue. I may have an a/c shop just bypass the heater core altogether so that there is no heat whatsoever. If that doesn't fix it then I have no idea what it might be. My last option is going to be calling Infiniti and seeing if they can take a look at it since it's still under warranty.

As long as the heater core is in fact not normally active. Otherwise it may come into play because of the heat.
