2011 BMW X6 V8 (4.4l TT) loss of power / shifting issue

I have a new 2011 X6 with the V8 and the new 8 speed transmission. Occasionally, under heavy acceleration, the car feels like it cannot find the next gear (not sure, but probably between 2-3 or 3-4 gear) at aroudn 4k rpm. This is pretty disconcerting as it could cause a problem merging or avoiding traffic and I feel it is a safety issue. The car violently lurches as it feels like it is trying to find the next gear.

I took this to my dealer and they could not find any faults and BMW doesn't feel there is a problem. Have any of you found this problem?

Thanks!
