External Temp Sensor

External Temp Sensor
My 2009 Vantage's external temp sensor seem to be overly sensative to sunlight in a way other cars have not. I would not really care but the external temp effects the A/C system.
Example, it was in the mid 80s yesterday and while driving the display was accurate. I parked the car (in the sun) and when I get in it a few hours later (do not think engine heat is the issue) and the display shows 106! So when I start driving the a/c is blasting. Within a minute or so of driving the display temp starts falling and in 4-5 minutes the display is in the mid 80s and the ac is acting normal. My work around is to turn the A/C off for the first couple of min until the display temp falls and then turn teh A/C on.
Is this how everyones car behaves or is my sensor faulty? My car is still under warrantee and before I have it looked at during my next service I want to know when the dealer says "they all do that" if that is the truth.

Yes and yes. My sensor reads around 120 degrees all the time. It's become the basis of a recurring joke between me and my girlfriend. Although it is common for cars to misjudge outside temps, the Aston is really bad with it. There was a service bulletin a while back (attached), but my 2011 still has this problem.
