Hi 2015 SHO, its happend twice now I pull up to my drive way and go to back in there is a terrible noise it kinda squeeks, clicks a bit and almost sounds like a grinding noise, the car also doesnt seem to want to move real good when its happening. then it acts fine and then I cant duplicate the noise. Any thoughts?

Not sure. Does it seem to bind? Are you turning, or, are wheels straight? Maybe the PTU....?

It happens when I turn. I back into my drive way. So I pull up turn the wheel to the right then go to reverse and crank the wheel to the other side and back in. It's when I've turned the queen and start moving backwards the noise starts and it does feel like a bit of binding.

Sounds like PTU. Take it to the dealer and demo this to them.

I bet it's the passenger side half shaft separating. There's a tsb for it.
I'll try to find it.

Just to follow up. It was the PTU. Sunday I was backing in and it started binding up and made an aweful metal noise. Took it in under warranty and they swapped it.
