Dead Stelvio, but dead battery?
I've been trying to get caught up and have not seen a conclusive solution to my issue.
Background: 2018 Stelvio Ti - 4800 miles currently, owned for 9 mos (since Oct 2018)
First Issue: March of 2019. Stelvio had been sitting for about 10 days in garage. Wife tried to leave and there is nothing...no lights, no electrical of any kind. The master mechanic in me thinks the newfangled machines with all their computers drained the battery in those last 10 days.
Being more handy than hansom luckily, I was able to connect my battery charger and get the Stelvio started the next day.
I verified charge status with my handy-dandy multi-meter and found charging to be indicated by a 13.9 V reading across the jumper-dealy under the hood and the ground pin. So far so go I thought.
Scheduled an appointment with the dealer JUST IN CASE. Few days later, took into dealer and got a clean bill of health. Dealer noted some software updates were required and did so.
Overall...I thought to myself...SELF...it's still a beautify vehicle. You still love driving it. This is just one of those hiccups that happen. NO WORRIES.
...and it's been love at first sight until July 24rd (of '19)...
Second Recurrence of First Issue: 7/23, all was well in Stelvio land. The wife had taken the grandson to the park. Came home, parked the Stelvio in the garage as is usual. Morning of the 24th, DEAD STELVIO. All the same characteristics of the first one. Absolutely zero electrical activity. Again, being handy as ever...10 AMP charge for 90 minutes and the Stelvio was able to start on it's own.
I left it running for 30 minutes to ensure full enough charge.
7/25 - no activity...dealer appointment made for Friday the 26th.
7/26 - Drove to work, Stelvio started up after sitting for 36 or so hours.
Dealer looked it over for two hours, said battery checked out fine. No log of any other issues.
SO...I do not think there is a charging issue...I think it would have indicated as such...and perhaps my lovely wife missed the message it should have been found in the logs.
I don't think it is a battery issue as with a partial charge, it was able to hold charge for 36 hours and not exhibit any issues when verified at dealer (from what I was told, battery was "load tested" with results well within specification.
As I was talking with my service adviser and the shop manager, I was told there are several Stelvio with the same challenges...and no one can find anything wrong. They have said that someone from AR is coming to the dealership next week (last week of July '19) to review these issues and help them resolve.
SO...Thank you for reading so far...
I know there are plenty of stories like this out there...has anyone been able to identify the root cause and solution?
I feel that there must be a few things going on...first, there must be some type of drain occurring? Maybe? ...and second...is there some type of master cutoff that senses the drain and shuts down everything? My HUGE failure was verifying battery voltage PRIOR to charging...I don't know why I did not think of that. FOR SURE if it happens again I will do this.
Upon implementing the charging, all manner of relays and whatnot start activating and whatnot...there is plenty of "activity" occurring once 12V is supplied under the hood.
Thanks in advance for any additional input. I am hoping some here had the same problem and I can point my dealer HERE for the solution.
I know I should not even be considering this, but I feel like this wonderful vehicle is now sitting in the suspect box. The wife is worried about taking it on a weekender trip...what happens if it dies when we are in a hotel?
