"When I'm at a complete stop and the light turns green I'll lift my foot from the brake pedal and before I can touch the accelerator pedal it seems the car will downshift into first. It feels like when you've downshifted too early with a manual transmission and the vehicle sort of lunges."
 
From what I understand, in order to save fuel (supposedly) the transmission sits in 2 when at a stop. If you hit the accelerator harder than the car expects then it downshifts first from 2 to 1 in order to give you more power. That hesitation might cause the driver to press on the accelerator harder since there is no acceleration. When the gears finally shift, you feel that extra power or lunging forward.
 
I do not know if that is what is happening but there are quite a large number of X3 complaints to the government regarding this issue with the GM6 AT.

You have to select the year/make/model/components - power train to see the complaints. The way you can tell if this is a problem is to use the MT or SD modes. Supposedly the SD mode starts in 1.

I was going to get the Lexus RX but I had a 5 series BMW before and I liked it very much. It wasn't particularly reliable but it drove great and was comfortable although not cushy like many American built cars. I just needed to get something more useful than a sedan and there were relatively few small SUVs available.
 
Now I have a car that drives poorly AND has lower reliability.
