SOS...DSLR overexposing / light meter NG or some thing else...Pictures added

SO my Sony a580 is now constantly over exposing by about 2 full spots.
Tried various things, different lenses, all metering modes but not much help. Either there is some wrong with my camera light meter or may be there is something terribly wrong that I am doing. Please please please help.
Adding some pics and some vitals for refernce

Picture 1) Aperture priority, f2.8, ISO 100, EV ±00, Sunny morning(around 9 ~ 9:15), AWB, Shutter speed achieved 1/400, Multi Metering........................way overexposed

Picture 2) Aperture priority, f2.8, ISO 100, EV -2 , Sunny morning(around 9 ~ 9:15), AWB, Shutter speed achieved 1/1250 Multi Metering

Picture 3) Manual Mode, f16, ISO 100, Shutter speed 1/125, EV -2, Sunny morning(around 9 ~ 9:15), AWB, Multi Metering.
Yes EV -2, I shot this pic keeping extreme left(minus) by dialing shutter speed of 1/125
Camera defying the Sunny 16

Picture 4) Manual Mode, f16, ISO 100, Shutter speed 1/13, EV ±00, Sunny morning(around 9 ~ 9:15), AWB, Multi Metering.
By dialing down the Shutter speed to a low 1/13, I could achieve EV ±00

Exposure compensation should have no effect in manual mode, right?!

yes you cannot set EV on manual mode. The last 2 pictures the EV values I provided are the one's I achieved after dialing in the Aperture value and the shutter speed

alright, just making sure ...

does this happen to all the pictures? maybe you have bracketing turned on?

I happened rarely but I didn't pay heed to it. But now almost every shot is like that. No bracketing, but the DRO is set to auto.
but I will still give it a check

have you tried more than 1 lens? it could be lens issue or body issue, try to isolate it.

How many shutter actuations?

I recall reading something a while back on DPReview's Sony DSLR forum re a sticky shutter.

By any chance were you standing in the shade? Or could your camera have been covered by your own shadow? I'm not sure how the camera fully determines the EV value but I suppose any shadow thrown onto the camera could affect it.

@ ds2chan : Initially, i thought waht you said as when i noticed the problem, i was indeed in the shade, shooting/metering in the sun. But today i rechecked it by standing and shooting in the sun.....same crap
