ok...so it seems to me that im adjusting my seat back all the time... i have a power driver seat. and at 6'1" tall i slide the seat all the way back. and tilt it back a little bit to be comfortable. well i can go shopping or run an errand and when i comeback out, ill be driving for about 20 mins and ill wonder why im sitting up so straight. i have to tilt it back a couple of inches all the time. iknow its only a couple of inches. but what the hell. im talking EVERYTIME! is this some sort of nissan thing?
