I think mine has the same problem but havnt checked it out yet. Ive been really struggling on slippy surfaces like worksop and I took it out on Ikea car park the other night and when putting the power down it just spins and always in the same directions and similar when breaking. Do people think I should check the things listed in this thread or anyone have any other ideas? Ive really been struggling to keep the back end from spinning out at worksop and just thought it was my driving but after testing it the other night Im not so sure.
