Weird. Maybe a short in the on/off switch on the dash?
Did you ever solve this? Our QX60 does exactly the same thing in the sun.Still not working...
It will not work for a few days, then all of a sudden it will work. Mechanic thought it might be the sun's heat overheating the module, but did not know for sure. It worked inside his shop, but after leaving it in sun, it stopped working.
anyone find the real solution yet?
also, anyone have a link that shows how to get to the module for replacement?
