Temperature going rapidly up
2nd time happening to me: I started my car, backed up and drove few hundred feet before stopping at a traffic light.
While stopping there, I noticed the engine cooling fan was running at max and the temperature was going rapidly up (in less than 10sec the gauge almost hit the red line).
While the gauge was going up I shifted the gear stick to P and the gauge dropped to normal in less than 5sec.
I shifted back to D and the car drove normally ever since.
Will take her for a check up but I'm curious what may be the culprit?

I would guess that one of the radiator hose is collapsing either because the hose is defective or the radiator cap is defective or the cooling fluid reservoir is not properly vented.

I took it in today...
First reaction from the lead mechanic was: it's a malfunctioning thermostat.
Upon further inspection he found bad thermostat, leaking water pump, and around half of the coolant was already out!
Not sure what would cause the thermostat to die, but it did.
Will let you know how the fix goes.
Thanks gentlemen.

I just got the car back.
They replaced the thermostat, water pump and the coolant.
I drove about 80 miles at various speeds with a lot of stops & go's. The temperature gauge is exactly at the splitting point between the two lines in the middle (it used to be slightly up most of the time with two times going rapidly up as described in the original post).
Thanks gentlemen for the input.

marylandlp:
I'm not sure why the low coolant light didn't come on, but maybe because it wasn't low enough to trigger the warning light. I never asked and the dealer never said anything about it.
I saw the area around the water pump. It was covered with coolant residues where it looked like the coolant had been dripping for quite some time already.
