Crazy that's how little a drain it takes to cause problems.
Did get the issue resolved - as expected, the battery was low (I even managed to jump start). Even then, "service engine" light was on (no mode shifting possible - N only), so the car still had to go to the dealer. The battery passed the stress test - so I did not manage to get a replacement under warranty. No direct reason for battery discharge was given (I am assuming all of the codes that were shown were bogus). My suspect is remote start through Alfa/Guardian app. It works sporadically - but may turn on the electrical system fully, even when it does not start.I had a similar electrical issues as described. 2k miles, 2021 QV.
First freezing temperature night of the year may of contributed, although the car was driven the day before. At attempted startup, plenty of codes flashed, then the car went to total electrical shutdown. Will investigate the battery as previously described, and report back.
Thank you. I had read the thread but somehow, that particular piece of info didn't sink in.Honestly, if you read the thread, you have learned that since your car was built, there have been several replacement flashes, and you don't know if they have been applied to your Stelvio yet. It's worth taking the car to the dealership and describing the problem just to have them apply the latest flashes to your car, which might resolve the issue.
The couple hundred bucks spent getting the most recent flashes applied (if your car isn't still under warranty, that is) are better in comparison to the hassle of dealing with random dead batteries that you can't figure out the cause, and which might be resolved after the updates are performed.
You know, it might just be worth locking the car for a week in the garage, just so that you can tell the dealer that this happens either when the car is left unlocked, or it happens both when locked, or left unlocked.The dead battery has been happening more frequently now, especially when I don't lock the car at night (which, why should I have to? My car is parked in a private garage, in a private house, out in the boonies, on a dead-end road "cul-de-sac") 🙃
I have been doing that. It seems to be okay if I lock it. Of course, lately, I have been getting nervous and plugging the car into a charger overnight. I have an appointment with the Dealer (Ramsey NJ Alfa Romeo) on June 7, so we'll see what they say. I guess I'll have to set it back to stock tune for the visit.You know, it might just be worth locking the car for a week in the garage, just so that you can tell the dealer that this happens either when the car is left unlocked, or it happens both when locked, or left unlocked.
Just giving them that extra bit of information might allow the tech to pinpoint the module that isn't shutting down as expected.
Try doing what I am doing; Lock the car overnight. It seems to be OK when I lock the car. If there is a software fix, I'll find out when I bring mine in on June 7.Hi all,
I just joined the Dead Battery Club yesterday. After normal driving, the car (2019 TI Sport) was parked overnight and the battery was completely dead in the morning. I had to use the metal key to unlock the door. There were no signs before it happened. I have a few months old AGM battery.
I know many members suggested that the root cause was the OEM battery but looks like it is not. Many members including me experienced sudden dead battery with new AGM batteries too. I am confident that there is a glitch somewhere in the system draining the battery. Although all the suggestions by the members make sense, I don't think they would prevent it from happening again and again...
I am fortunate to have many lux cars in my life BUT never experienced anything like this...
I was wondering if anyone has discovered the real root cause....
Thanks in advance!
The one thing that you need to remember is that what may have been the solution for one person and their car may not always be the same solution for you and your car.I was wondering if anyone has discovered the real root cause....
Thanks for your input. Definitely your suggestions make sense.The one thing that you need to remember is that what may have been the solution for one person and their car may not always be the same solution for you and your car.
There have been so many different code iterations to cover a variety of problems, that you can't really compare two cars, unless they just rolled off the assembly line within a few hours of each other.
Pretty much, the only way to determine what the problem is is to have all the fuse block covers off, and shut down the car.
Wait about 30 minutes, and scan the fuse blocks with an infrared camera to see if one of the fuses is hotter than all the rest.
If you're lucky, you will be able to find the fuse that has the most power going through it.
If you are lucky, then you can determine what modules and parts of your car are fed by that fuse, and start your troubleshooting there.
If you wanted to go further, you could pull the positive battery terminal, and connect a digital volt meter between the terminal and the lead, with the range set to milliamps, and watch for the amount of power draw after you shut off the car, and after it goes into deep sleep mode. If you see a large draw at that point, you can search with your infrared camera in the fuse block for the source of the draw, or you can start pulling fuses to the fuses that have some of the higher draws, and see which fuse causes the drain to vanish on the DVOM.
Again, the idea is to narrow down the source of the draw, and then go from there.
Maybe there's a flash for that module or part due to the large draw.
Maybe you need to replace that module or part due to it being faulty, or there was a production replacement because of this issue.
You just never know until you do your best to become a diagnostician.
Gut feelings are great, and sometimes can be right, but the problem is that gut feelings don't narrow down the actual problem.Thanks for your input. Definitely your suggestions make sense.
Although I agree with you that each car is different, my gut fleeting is telling me all/most of the vehicles suffering from sudden death battery syndrome share the same problem…
