I purchased a XBOX 360 PRo in March. In November I turned the unit on and hit had an E74 error. I contacted Microsoft and sent it in.

They sent it back and it still had issues...I sent it back to them and they sent it back saying it didn't have any problems.

I called in and they sent me a new power supply suggesting that this might fixed the problem...it didn't.

I sent the xbox in a 3rd time and was told by tech support that they replaced it with a new one...

They shipped it back and it is lost in shipping...Microsoft is telling me that it's fedex's falt and there is nothing they can do. They did say if it ended up being lost it could take 6-8 weeks to identify it was lost and then 6-8 more weeks to decide what to do about it.

I have a BBB case open as well as a complaint with the Consumer Protection Department in Washington.

Also on the 4th repair I was told they would only replace the fans in the system and that should fix it, but instead they replaced the entire console.

Had I not had to send this console in...none of this would have happened.
