Has anyone experienced this before?

When making a 90 degree right hand turn, which is slightly down hill, in 4th gear, below 2000 rpm, the TCS comes on after a few seconds and then stays on for one tenth of a mile?

Note - the rear wheels are not leaving the ground, going the same speed in any other gear (1,2,3,5,6) through the same turn does not cause the TCS to come on.

Can reproduce at will, as long as the turn is 90 degrees, and down hill, even slightly. The dealer was able to reproduce, but not fix the issue.

Any ideas or suggestions - has happened since the car was new (50 miles) now has 15,000

Thanks
