The first thing I will do is change the dunlops to bridgestone. They are better comfort wise and performance wise. As my dunlops were wearing out, everytime I accelerated the traction control would come on and cut the power thinking that I was loosing grip.....I took it to the dealer several times and the QC even drove it, and experienced the problem. They told me it was because of the tires. I didn't believe them at first. But then I changed the tires and everything went back to normal. 2009 xdrive48i sport pack and adaptive drive.
