While accelerating my 2003 kia Rio onto the interstate while going uphill, the car's transmission slipped and had no power on the incline even when it was floored. It always does this when passing cars also. I took it to the dealer who said they could find nothing wrong with it. My brakes lock up when they are damp. I did not think this was a problem, but it is.
