Thus I don't see the harm in posting on here to see if it's a common occurrence or not. You'll have to excuse me for wanting everything on my brand new car to function properly.

What other temperature reading are you comparing the vehicle sensor to?
Temperatures outside can vary due to gusts of wind, sun exposure, etc.... its hard to get super accurate readings using a single temperature probe.
If you find its always off by a certain amount, looking up the sensor information and find out of if its a simple thermistor and what the voltage/temperature scale is, then clever application of a resistor may bring the results more in line with what you deem accurate.
I find that mine is accurate within reason, as in a rough estimate of the outside condition.
You could probably pull the sensor off, take it to a climate controlled room, check resistance and compare it to what it should be reading at a certain temperature. This information might even be in the shop manual, I've had good shop manuals that let you bench test most sensors on a car if they are able to be bench tested
