Me also, have a 2018 and dealer just replaced the battery. No cost to me (this time) but it failed inspection as emissions data lost. Had to go back later.. Just want it FIXED! Love it otherwise.Bradley, I have an 2011 QX56 and I'm having the same issues.. I've had mine at the dealer several times and they can't seem to figure out the issue. I'm seeing the Nissan Armada is also having the same issues.. Infiniti only tells you to take it to a retailer. I feel a class action lawsuit should definitely get started asap.
Tom count me in.. Having the same issues with my 2011 QX56, the dealer cannot figure out what the issue is... Class Action Suit is a must.
