The driver seat preset issue is most likely due to bad side mirror actuators. There is a TSB addressing this. You might even get some goodwill warranty consideration if you have a nice dealership to work with.I have a 2007 MDX Elite 20th Anniversary Edition which seems to be an electrical lemon.... The Handsfree link just died but comes back to life for 5-10 minutes every couple of weeks, the auto seat adjust starts to work but then stops so you need to push the button like 5 times to get the seat and mirrors in the final position, at random when you unlock the truck with one tap of the remote all the windows and sunroof open and no I'm not holding down the button, I am on my third battery in a year and it only has 90,000KM or under 60,000 Miles, Anyone HELP PLEASE!!
I might have wrongly blamed the memory module earlier. The common problem is, as mentioned here, actually with the mirror actuators.
