If you leave it sit, do all the corners hold position and they are just off from one another? I suspect someone has done some work along the way and not properly recalibrated it. You need someone with GT1 or INPA software to reset the corners. You can use the software to raise and lower each corner in small increments, validate the measurements and reset the home position. A good independent shop with CarSoft should be able to do the same.
