Dario, my new to me 2017 First Edition just crapped out after sitting for 5 days. DOA, nothing. Jumped it to drive it home from the airport. All kind of noise, lights, clicking away. After turning the AC and infotainment systems off, it drove normally the rest of the way home. Pulled the battery out hoping it was 4 years old and ready for replacement. Nope, installed 4/21. Can't think what I could have left "on" when catching my flight. Hope it was something. I have it on a charger now, but will purchase a new Interstate AGM Group 49/H8 from Costco ($179 - screaming great battery prices) and install this afternoon. Will give it 15 mins, setup my Gap Tool for this vehicle, do the battery recalibrate function, and look for a peristatic draw or other issue.
What was the feedback from your dealer?
