S680 Lateral tilt problem

I have a 2 year old 680 last year the tilt started to just randomly go one side or the other. My dealer could not seem to fix it. at the end we thought a software patch created the problem and reloaded the computer. when I got it out this fall, I found that when I raised the reel the header tilted. turns out that raising the header, moving the reel, any direction, stepping on the brakes. All will create a lateral movement. my dealer came out and put 12 updates into the machine. i have calibrated the tilt and the header, it still does it. Any ideas?
