mercedes me connect app / critical starter battery message
last week i dropped car at dealer to have tires swapped and over the weekend i get the messages that starter battery is critical. i decide to have the dealer look into it and no error messages on the car or observed issues with the batteries.
anyone have a similar experience? is it just the app? or is something truly draining the battery and i just happen to always restart it before it’s truly too late?
Just got back from another holiday, 5 weeks in Canada, and received 2 battery warning messages while my car was at the airport.
It is a bit worrying when you are wondering if your car will restart while on the way back home.
Is it an app issue? The car starts OK after these messages but still gives an additional warning once the car has started.
If it is not an app issue, what is creating the battery drain? Sending warning message?

I was getting those messages when the car was new, but put it on a battery minder for 48 hours and haven't seen it since. The voltage as delivered is nominally fully charged but an AGM charger will charge it considerable more. I use this one, which I recommend highly:




The communication module for the app seems to draw considerable amount of power and it gives away messages as the threshold gets near the min for the communication module

This is how I got rid of the issue on all 4 of my vehicles (2021 GLE63S, 2021 G63, 2021 GTC and 2020 GLA): charge them at least 24 hours on the MB brand trickle charger. Other brands may work - but only if they are specifically made to charge LiPro batteries....and most aren't. My dealer just gives me a charger every time I buy a vehicle, so I just use the one made by MB. I charged the G63 for about 2 days before its battery charge finally registered 100%.
This made the error go away completely. Any vehicle with the 48v system in it is particularly vulnerable to this, and MB has been having a devil of a time with their batteries due to frequent manufacturing defects. The company also doesn't seem to by in any hurry to correct catastrophic issues such as the 2019 GLA's not being able to EVER start in cold weather.
This is why I think that this current crop of AMG's are the last that I'm going to buy from the company for many years. I'm switching to the VW Group Products such as Porsche for the family - at least until MB wakes up and gets rid of its current CEO Swedish nut bar climate **** who is not into cars. I think that the MB company is going to tank under this guy - it already is, which is very sad.
Well - you're a great dog parent. They're lucky to have you. I would do anything for my dogs as well.....well, I kind of HAVE to or I'd have to deal with a house full of very dangerous and angry women! ;-)
Sometimes being loyal to your car brand is just like surfing a great wave. Awesome while you have it and makes for great memories....but when the ride's over.....it's over. No sense being mad about it. All great waves peter out eventually - maybe that's a good thing. Keeps incentive eventually reinvigorated for these car companies!
Lots of other waves to ride out there, and who knows....maybe Mercedes Group will reinvent itself and get a car enthusiast running the show again one day.
It's too bad that climate ****'s are usually not all that smart - even though many of them may be "educated". Time will tell how this all shakes out.
why you posting in G class, as well posting this in AMG 205 threads etc.. and you know its complete BS DUDE!!
as soon as your car looses connection with the KEY , it starts alerting you to hell and back, and will keep dinging , displaying it on dash, etc etc.. if you were stupid enough to turn your car off with out the key , then thats on you.
(more so, if the car is NOT in drive, and it doesnt detect the key, as soon as you touch brake pedal , the car will shutoff as well) <- this is due to the remote start function.
When doing system updates etc, they recommend to put the key 50' plus feet away, so the car doesnt see it.. so its possible in his house it still saw it.
Although, as soon as he pulled out, the dash would/should have been lighting up and telling him its an issue.
What year S550 ? I have done mass amounts of coding on these and do not see any way/reason this is possible , unless something was messed with.. any mods on that car ??
However, I'm skeptical that a vehicle can be started while the key fob is not inside the vehicle, but located outside some distance away up to 50 feet.

And yea, it should not detect it at 50' , that is why they say put it 50' away when doing system debugs, so the car can goto SLEEP 100%
