mercedes me connect app / critical starter battery message

so i’ve had my 2019 g63 for about two months now and i’ve always gotten a message from the mercedes me app after the car sitting for a few days stating the starter battery is in critical state. i’ve never really worried about it and car has always started up even after getting the messages.

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?

I've had the same messages after 2 weeks while on holiday in New Zealand but the car was still on the drive so I was not too worried.
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?

For 5 weeks, my E63 would need to be put in standby. Doesn't the G have standby mode? The radio communication that supports Mercedes Me uses significant power, and standby mode cuts that.

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:

I get the exact same thing on the ME app if the G sits for two days. I have been putting a battery tender on it to bring it back up. Glad to hear it is probably just a fault in the app. I will quit worrying about it.

I had my g63 at the ppf shop for 1.5 wks and I continued to get this message. Had them put the battery tender on and have been driving it, may be 5 days a week, no issues since.

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

Hi, I have a 2017 E200D Sedan and I have been getting the Critical Starter Battery message for a number of weeks. I haven't been using my car very much due to Covid-19 travel restrictions so it is sitting in my driveway most of the time.

I've had my 2019 G550 parked for 2 weeks without use, and yesterday it fired right up no differently than normal. Comm modules can suck power -- kind of ironic that a system intended to advise owners of a low battery state causes the low battery condition to develop. Kind of like a fire alarm that's prone to short-circuiting and erupting in flames.

Exactly the same problem with a 2019 E450 Matic Convertible. It’s very annoying, I’ve just driven it for 40 minutes and still get a warming message from the app saying “starter motor battery critical”.

It could be a marginal battery. If you use the ECO Start/Stop mode that kills the engine and restarts it every time you brake to a stop, the demand on the battery is severe. Have the dealer swap it out for a new one. Or take your E to an auto store and have them put a battery tester on it to determine its condition.

I have had a similar issue since I bought my new clk 300 2020 after 10 months got starter battery partially charged they ended up replacing the battery after car had been driven 6 k wanted to charge me 500 dollars even though I just learned I was underwarranty thankfully I argued well what do you know now 10 months 12 k miles same issues. They tested the batteries using the most advance technology but this time I persisted so they did a manual test and the battery failed even though their computers said the battery was ok so thankfully they now no their is a problem but they don’t know what it is so they opened a case with Mercedes’ Benz. So if you run into the same issue have then manually check the battery and be persistent now they put in a brand new battery second one in 2 years if it happens again I’m coved .

This is a common issue with the voltage on the vehicle that is depleted substantially after it ships. For some reason, the alternator in the vehicle doesn't sufficiently charge the LiPro battery to 100% no matter how much you drive it. The dealer told me that this is a matter of a "software update" - but MB has been aware of this issue for at least 3 years with no resolution to the issue.
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.

I have to agree I sent a note to the German ceo because did you know you can drive your car without the key fob being in The car and end up stranded on some highway in the middle of no where once you stop the car. Try it start the car then throw the key out the window not fun when you have 2 dogs just had chemo and it’s 120 degrees outside nothing form the **** clowns no even an apology the system doesn’t ring or warn you that the fob is not in the car like other cars do 68000 dollars for garbagio. What happened is I started the car and got out to pick up something on the garage floor unknowingly the fob fell on the floor and I got back in and drove off. Was stranded at a dog park for over 2 hours thinking I had dropped the key in the grass imagine having to dump out all the pop bins then thinking I had maybe thrown the fob out with the poop bags . This will be my last Mercedes’ I have been a loyal customer for over 25 years

Oh man! I'm so sorry that that happened to you! And your poor dog on Chemo!

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.

That same kind of thing happened a few years back to an acquaintance of mine. He started his S550 in the garage, but the key was in the kitchen next to the garage. It let him drive off to the grocery store where he got out and went inside to shop. Came back out and realized he didn't have the key in his pocket. Luckily it wasn't nearly as bad as you experienced, but strange that you can drive the vehicle without the key inside.

So your 2020 CLK 300 is what we are talking about here ? I call BS on that as well.. show us a pic ?? Mainly since they stopped making the CLK's in 2009 , and more so, never a 300 , so how much BS you want to keep posting about ?

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.

It would have been BEEPING at him like mad .. if the car detected the key when he started it, then it will maintain and run, it checks again, when you push brake pedal, then from that point it expects it.
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 ??

Once the vehicle is started and is running, it's possible (and convenient) to exit the vehicle with the key fob in-hand while leaving the vehicle running. If you then lose the key fob and shut off the vehicle, you have a problem.

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.

I agree to some point, but if you start you car, and keyfob lets say is in your pocket, then you go inside and put the key on counter then go get in your car and press the BRAKE pedal to shift into drive or what ever, it will shutoff if it doesnt see the fob. (this is a safety feature) ( same as with remote start )

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%
