Can anyone help with a possible diagnosis? I’ve brought this to my dealer 3 times and of course they cannot replicate the issue having it multiple days. 2020 Qx60 has intermittent start issues. Key fob works, unlocks doors, etc. and when I press start button, radio, air, lights etc. all come on but nothing. This can happen several times a day or a few times a week. Sometimes I give up pressing the button and then it randomly starts on its on with my foot still on the brake of course. I’ve replaced brake switch, key fob battery. Dealer states they have checked all grounds and no codes. At a loss.
