Hello and welcome to JustAnswer!
I see that your question has been up for an extended time without a response and while though this vehicle isn't in my area of greatest expertise I would like to try to help.
There are a few things that could be causing your problem.
The memory seat functions are controlled by a module and the problem could be the module itself. The first thing I would recommend is trying a battery disconnect and see if that helps. Sometimes removing power from a module can at least temporarily fix issues such as this.
If that doesn't help then a scan tool can be used to look at data and see what is happening. If the module is seeing the switch pressed when it actually isn't then the seat is going to move, this could be the switch itself, wiring or the module. It could also be a seat position sensor or wiring issue, or the module itself may just be moving the seat for no reason, in which case it would need to be replaced.
Thank you for answering. This is intermittent too. It moves the seat overnight into an upright position. The seat position if I am going uphill. I think the dealer would charge me lots to troubleshoot. Just got to go to the dealer or is there another way to get the scan work done. I wish I knew where the battery was located.
Overnight it moves upright. The back recliner is the part that moves the most. It moves forward towards the dash. I hear a beeping sound from the module about 10 beeps when I use the manual control buttons to stop it from pushing me into the dash. Is it possible for me to disconnect the seat from it electronic base? Can a module be repaired? It seems like weight distribution causes it to happen more frequently especially when I am going uphill. Almost as if the car senses it is unbalanced.
I guess the manual controls would not work either. Or would it?
