I was wondering if it is ok to leave your cc weapon in a hot car? (or extreme cold) it gets pretty warm in my car during the summer. I have a polymer gun also.
Extreme Temperature a problem?

I think it's ok as long as it isn't in direct sunlight. More for finish and evaporative reasons. Firearms aren't made by Hasbro. 
Temperature will affect the pressure created by a given round, but only would make a difference when you are near extremes.
Example: an IPSC club I go to required competitors to leave their ammo in the shade prior to testing because some shooters(cheaters) would load their .45ACP rounds just below Major Power factor levels. Then, they would leave their rounds exposed in the sun until just before they were tested to check if they make the Power factor minimum. The heated rounds would make the power factor due to increased pressure and would be approved, but later when they cooled down would fall beneath the required levels and supposedly be tamer recoiling.
Another example: I once reloaded very light loads with just enough powder to work the slide during the summer. During the winter on cold mornings they would no longer develop enough pressure to move the slide completely.

Guns are made for war, stop worrying about it.
It can get to 140 degrees in Iraq, and that hasn't stopped anyone from killing each other there.
In your case, polymer guns actually do better in extreme temperatures because the plastic (polymer) does not expand or contract like metals can, nor will it get brittle in low temperatures.

How about lubricants breaking down in extreme heat? I would think that could be a problem but it would need to be pretty darn hot. How hot are most gun lubes rated?

Most gun lubs will be fine in high heat, after all steel frames can get HOT when shoot a good bit on the range. I would keep a eye on them to make sure the heat doesn't cause it to evaporate a little quicker than average, other than that it will be fine.
I use Gun Butter and that stuff never evaporates, but the old Rem Oil, it'll be gone a little sooner than normal if you leave it continually exposed to heat.

Lubes will generally be rated for high and low extremes. Break free is rated from -50C to 250C (couldn't find in F)
The pressure in the bullet case would scare me more, and over time worry about effectiveness of the power would be a concern.
Overall, my biggest worry would be theft. Look into options for securing it in the car if you must leave it.
