I have read all the postings about the seat memory issues with the M7 transmission. I am having the same issues with my car with an A8 transmission.
Facts--seat moves to the memorized exit position when exiting the car. Settings is set to return to the memorized seat position when the ignition button is pressed.
Seat will not consistently move to #1 position when the ignition is engaged, so I have to hit the #1 button to return the seat to the preferred driving position. It works occasionally but not ever time.
Also getting the system to memorize a position does not work consistently when in the car with the engine running. If I turn the engine off then the system works as described in the manual, but with the engine running it sometimes returns to the old memorized seat position rather than memorizing the new position.
I may have a software problem but checking to see if any others with A8 transmissions are having similar issues.

2 things to check:

1. Make sure the exit position IS NOT all the way back. If the seat engages the seat limit switch automatic functions are disabled.
2. Make sure you are always using the same FOB. Each FOB is tied to a memory location (1 or 2) so if you have a different FOB in your hand or pocket the seat will go to a different position. For example, you may have FOB 2 in your pocket but are saving to memory position 1. When you use the "On Start" option the seat will go to position 2, not the new setting you just did for position 1.

Thanks for your thoughts. I read the challenges with the seat memory function posted elsewhere on this forum so the exit position is not all the way back. I have only used one FOB since I got the car so FOB confusion is not causing the problem. As I noted above the problem is the same as those with the M7 transmission--exit position works but return to driving position using the On Start option does not work. I have to hit the #1 button. It does not move to the #2 position or any other movement. It just stays in the exit position until I hit the #1 button. I have been to the dealer. They played with it and got it to work once but then it failed again. The service manager is now talking to GM but they want the car left there. I am having fun driving it so pressing the button is an ok fix until I have to leave it at the dealer for an oil change or whatever. Meanwhile postings re seat memory problems is a topic on numerous corvette forums so maybe someone will realize they have a recurring problem.

While at the dealer did they take the time to refresh the code in the seat memory module? That should have been the first thing they did. If that was done it sounds like a sensor is either failing or disconnected, they need to run a full sensor test on the car. Those tests access each sensor and can pick up issues that may not push a code.

Thanks for advice. No they did not do anything you recommended. I will ask them to do so.

How do you tell FOB 1 from FOB 2?

FOB 1 is the one I put in my pocket when I first started the car. FOB 2 is the one I left in the house. Obviously I have no idea how to tell the difference!

How do you tell FOB 1 from FOB 2?
1. Set different seat positions for Memory 1 and Memory 2
2. Enable "On Door Open" in the memory recall setting
3. Move the seat to the exit position, assuming that is not all the way back hitting the rear limit sensor
4. Press the unlock button on your FOB

The position the seat goes to, memory 1 or memory 2, will tell you which FOB # the FOB you just pressed unlock on is.

I have an A8 with the same problems. When the seat goes to the exit position the side mirrors shift all the way out. When I start up they do not move back. I have turned off the options till I can get to the dealer.

Thank you...I'll give it a whiz.

I had a similar problem on my Z51 3LT with an A6. I took it to the dealer for an oil change today and mentioned it to them. They had the same problem when they tried the seats. They reset the system and all works fine.

Thanks for the heads up on identifying the FOBs. I found I was using FOB2 to try to get the seat to go to memory position #1. Looks like the problem is solved which means I have nothing more to do than enjoy my C7.

It could be that many of the seat memory issues posted on this and other corvette web sites are based upon the lack of knowledge of the difference in the two remotes. I found nothing in the manual that tells the owner that the two remotes are programmed differently.

This is above my pay grade, but I wonder if when owners take the car to the dealer to have the system reset, the resetting process may pair the memory system with the remote the owner gave to the dealer when the car is in for service. So when the owner picks up the car all is fixed since the remote now responds to reset memory system. Just a thought.

Thanks again.
Doug
