My 2011 G37coupe will occasionally not start when I press the button. Some
time after it will start, and then the windows will reset at a lower level. I have a
new battery - brought it to the dealer and they seem clueless.
Well, keep trying to find a mechanic who has a clue- this is an example of how owners should not even lift the hood on these 21st Century cars- and how GOOD mechanics are more valuable than ever- and should be paid in gold-
Ok- here is my attempt to be helpful- did you try jumping that car? did you short something out when you changed the battery? the symptoms sound like some kinda gremlins in the electrical system- why should the windows act funny? idk
Check battery IN FOB, as well proximity of fob to ignition switch before digging deeper.
