The people over at TechnicBRICKS have posted a communication from TLG about the faulty 8043. Check it out.
I put a battery box in the machine and ran it literally for about 30 seconds and then took it apart. I didn't want to ruin the motors as many have already done. But you can be assured that I will be contacting the Lego Group for my Service Bag to fix it.
I am actually surprised that they were able to fix it. While I was building mine I noticed that the movement mechanisms were packed quite tight. It didn't seem that a fix would be possible. Kudos to TLG.
