Power seat

I have a 2006 GTP coupe with power driver's seat. (Wonder how come a power passenger seat is not even an option?)
Almost since new, the seat would stop functioning in the forward/back mode while retaining all other functions. The dealer investigated and found the switch had come unplugged so reconnected it and that seemed to end the problem except about a few weeks later, the seat started jamming again and so this time the dealer put in a new switch. Within three days this time the problem was back.
The 'sticking' lasts anywhere from a few minutes to two or three days; ever try to drive a standard when the seat is stuck in the full 'back' position!??!
Has anyone either experienced a similar problem or has found a solution to the problem?
