I'm driving down the mountain, rounding curves approximately 40 MPH when the ESP lite comes on and I feel a little vibration in the gas and brake pedals. When I push the brake pedal, I feel a thump, the lite goes out and the vibration stops.
Any ideas? I changed the brake lite switch because that's what the dealer said was wrong. No improvement. The last trip down the hill showed no codes. ???
