I don't think this applies to your problem but I will post it as it is the
same problem I have at times with my 2004 Yukon.
It has all the bells and whistles and the memory seats. I have had the
program reset in the computer by the dealer twice
while it was still under warranty. Now that it is out warranty, I just
reset my preferences about once a month. It will do the same
thing you discribe. When I get it, the seat will crunch me into the
steering wheel unless I reach down and stop it. I have found
that if the truck has been unlocked with key fob 2 and I get in with key fob
1 and insert my key, the seat will usually screw up.
So, we try to lock the truck when we get out every time, even if it is in
the garage. That way the fob that unlocks the truck will
be the key that is used. That is the only thing I can find to kind of fix
The dealer told me that in later year trucks, the fixed the problem. (pigs
