I just had noticed on my MDX that the drivers seat will only go back and forth in 3 inch intervals. It starts to go and then stops, if I release the power switch and continue it will go another 3 inches and stop and if I release the switch and hit again it move another 3 inches. Very wierd, the memory will not work with the forward and back just the back tilt and height. I can move it using the switch and just have to keep hitting and releasing and then hitting again. It will only move in intervals. Any experienced this problem before? Any idea on where to go before I bring into Acura for a look???
