Canon EOS 650D images over exposure (viewfinder vs liveview)

I used to have a Canon 450D with Sigma 17-50mm f:2.8

I was using the camera for family photos and using it in P mode.

I am always shooting RAW since I want to get the best result from my camera. After shooting the photos... I was doing just minor correction in Photoshop. Sometimes I was making no corrections... I was satisfied from the result.

A few days now I sold my 450D and bought 650D (I wanted to have video too)

So I took my camera.... I put almost the same settings I was using with my 450D.

After 2 days I realised the following problem

The images came out over exposured!!! I was surprised since I had to correct ALL the pictures in Photoshop in order to get a correct exposure.

So I started playing with the camera settings to has what was wrong...

As a result.... the camera (when using the viewfinder) gives almost 1 f stop more exposure... the image becomes too bright

I tried shooting with liveview and the camera was able to select correct exposure.

I tried different metering modes but the same problem exists.

The only way to correct the issue is to put -2 in exposure AEB

This corrects my photos but then the liveview becomes too dark!!!!

I googled this issue and find out that many people have this problem...

Any ideas? any fix? I can upload sample images to see what I mean.

By the way... when I use Manual mode I do not have a problem... same image on both viewfinder and liveview.

The problem is that I can not use any AUTO mode

VERY DISSAPOINTED

I found that exposure metering is something that can be miscalibrated. see old thread:

most "problem" posts are about misfocus, but as my experience shows the exposure metering system can also be off. I think often it's brushed aside as wrong operation, or one simply uses correction, so it's not on people's radar like focus issues.

If you take an image of a grey card (too bad you don't have the old camera anymore) and see what values you get (compared to other body and life view). you can then send it to canon for calibration under warranty.  Check that centering (spot) is also ok, like in my thread.
