Your camera is under warranty.  You should get it checked..  For all we know, the delivery box may have been dropped and bounced around a few times before it arrived at your house, and damaged the camera slightly.  It could simply be misaligned.

Im comparing this to my friend who's using a 6d with the same lens,50mm1.4, and he shots car photography at 1.4 with no issues at all.

Bad lens.  Let him test your lens on his camera body, and vice versa.

[ Edited ]

Some more samples i just took.  Both done in single point af, pointed at the front door handle, using back button focus and single shot.

 

blurry one

f1.4

iso 100

shutter 1/1600

 

clear one 

f5

iso 125

shutter 1/200

 

took 5 shots, f1.4, 2, 3.2, 4, and 5. F5 was the clearest. All others came out blurry. Progressively got better by closing the aperture.

I think it has been pretty well established that your issue was a misunderstanding of the 45 point AF system, and that your 50mm f/1.4 needs AF microadjustment. 

 

Your AF microadjustment of your 50mm f/1.4 which you said had improved its performance that he said you should undo was what I was referring to, when I said telling you to undo something that worked was nonsense. 

 

I don't think there is anything wrong with your camera. 

 

I'm not certain if there is anything wrong with the other posters camera or not, but, eliminating other factors like we did with your camera is important before simply saying send it back.

 

It is next to impossible to judge how far an AF system is off using a 2D target.

 

In Canon's AF Microadjustment Guidebook they address this, and recommend a vertical target set up on grass, so you can see where the focus is actually falling. (front or back)

 

If a camera requires extreme AF Microadjustment (> +/- 15) with all lenses, yes it probably needs a trip into Canon as it is likely out of tolerance or certainly on the edge of it.

 

However if it requires smaller adjustment with most lenses, or some lenses require positive adjustment and others negative, then that indicates there really isn't an issue with the camera.

 

For the other poster, forgoing AF Microfocus adjustment and simply sending the camera back in my opinion is a waste of the user and Canon's time.

Someone recommended the reikan focall software. I was going to give that a shot

I had poor luck with that software.

 

Just follow Canon's AF Microadjustment Guidebook

 

Prior to Canon releasing that guidebook I recommended using the 'DOT Tune' method, but, at this point I would use the methods described in Canon's guidebook.

Thanks for posting the link. I was just unsure because he said to send it back because its bad. When i did my adjustment, +8 and +12 made it worse. +10 seemed to be perfect for me.

Did you make the adjustements with the aperture wide open.  Your “blurry” shot looks like it front focused.
