ive the same prob on my hgt and had it a day or so after buying it. i have been told to take it bk into them and its booked in. good feature really, i imagine really helpfull when driving in bad weather and sitting on a uphill. thing thats really pee'ing me off tho is that when it fails..which is about 50% of the time, it turns the esp off. so then my abs and traction contol doesnt work.
