I've had the car a couple weeks now. I was coming home from the gym and after taking off on an icy patch with some fair amount of slipping, the hill start assist light came on an won't go off. I plugged in my AP; no codes. I also cleared the codes for good measure. I unplugged the battery. I also performed the procedure for deactivating/reactivating the HSA that I've read about in other posts. I haven't seen any blown fuses. This is the only light that's on. Any ideas? Did something just get wet and need to dry out?
