"Now, it was my turn behind the wheel and I too experienced the loss of power nose-dive, when I used either the automatic drive or the paddle shifters when trying to merge onto a freeway."
As most test drives from the tour were on a short closed course, few of us experienced this nose-dive, while merging problem.
My wife and I both ran into this on our test drives in Bloomfield, as we we had to merge from a rolling stop, into fast moving traffic (50-60+ MPH).
I posted about this on this forum in July.
I can't believe they didn't fix It.
