I'm coming up on 6 months of ownership on new 2024 GLC. I am a low mileage driver, daily commute is around 10 miles. I get a recurring warning alert "the starter battery charge status is very low. To ensure the vehicle will start, drive 30-60 miles, or connect to a battery charger". I've had the same commute for over 30 years, and owned Chevy, Ford, BWM, and have never experienced this issue. My local Mercedes service manager tells me the Mercedes "fix" is to take a "sunday drive", or use a trickle charger. This is Mercedes' new "hybrid" design, supposed to be more fuel efficient. But in my case, any fuel savings are offset by required "sunday drives". And who is going to pop the hood and hook up a trickle charger?? Seems to me the Mercedes engineers erred and delivered a flawed design. I've asked my dealer, what the "design" miles per day requirement is to avoid this issue, so far no response. Any one else having this issue?

I had the low battery issue as well. It ended up being related to overspray on ground wire during production. The technician cleaned the overspray off and they replaced the starter battery. Have not had any issues now for several
months. I hope this helps others with the problem.
They fixed the same issue with me by performing software updates to all four doors
Yep, same here.

I recently had this same problem. Left my 2024 GLC300 with dealer service. Finally they discovered the problem was a defective battery sensor. Once replaced i have had no further issue.
I'm still working through the Maryland lemon law process, working with the State Attorney General. I just passed one year of ownership. Mercedes continues to maintain the solution is on "me", go for a 30-60 mile drive, and/or install a trickle charger. Ridiculous. I've had it in to Mercedes service 4 times, each time a "software update". Still the issue remains. Fortunately, it's never actually been not started. I started checking batter voltage, and it is borderline at failure, 12.04V vs 12.6-12.8 normal.

I had the same problem, they finally fixed it by doing software updates to all four doors modules. Previously they gave me the same answers as they gave you, it must’ve been their standard answers.

Sorry, I didn’t keep it. I service my car at the dealership I bought it from; Nanuet, NY. If you call up a service manager there, he will probably tell you what the recall service was. I had it done about 3 months ago and so far it’s been resolved. Good luck!

As I've mentioned before Mercedes has better get it together there is no excuse for customers to be complaining about one thing or another or making excuses about so many different issues from chrome that peals or fades or gas door to battery problems. Who's really running things and allowing the great Mercedes name to be tarnished? No excuses fire the bums

I have a GLC3 from 2023, it has had this issue chronically. To the point after only a few days sitting idle it wouldn't start and had to be towed to the dealership. I have actually had the car give me the critically low 12V charge warning on my phone when the car was sitting at the dealership, TWICE! There is an option to put it into Stand By mode, but when I tried that my car said the 12V battery did not have sufficient change. This is after driving it all week, including a 60min commute home when I tried to put it into Standby immediately upon parking it. So took it to the dealer again. Every time they just say it's a software upgrade and to drive it more, including that recall that I see many others referencing. This car can't sit more than 4-5 days without the 12V going critically low. I don't know how this is not a class action or full recall at this point. If it is software, the issue is systemic. If a car needs to be driven at least every other day for many miles to stay functioning that needs to be called out up front as part of the purchase, not standard expectations for a new (or any car) from my perspective.
As you may have noticed from my other posts, I have been in the same situation as you but yours seems to be especially bad. Regardless it shouldn’t be this way. I don’t think there has ever been an official recall on any of these newer GLCs, just TSBs. Have you had the door software update done?? That is the most important update.
Rocky, thanks for the quick response. Yes, this has been a frustrating experience. I like the car just need it to be reliable. Correct, no broad GLC recall that I'm aware of either. I was just referencing that door software, that was corrected the first time car the demonstrated an issue. I think it helped, it can now sit for more than 3 days. But for sure did not fully address the issue. I hope yours was ultimately resolved.
Not fully resolved. Nine times out of ten (driving locally) there will not be enough battery charge to allow the standby to engage, but at least it has always started. Also the check engine light comes on intermittently but nothing seems to be out of wack due to that coming on. I just rationalize all of this due to the fact that modern cars are so hopelessly complex. I just wish someone would make a high quality, nicely designed car that was simple.
I have a very similar issue with 2024 GLC which I got in July. Even after running 100 kms at times, if the car is parked for a couple of days the App shows "partially charged" and if kept unused for over 4 or 5 days, I get a "12V Battery Low" warning on the app and also on the dashboard. However, it has started each time. I twice reported it to the Service Center and once they kept it for 2-3 days and updated all modules (including Door Control Module which many have reported as a possible issue). However, the issue has not gone away. At times I have tried putting the car on "Standby" when there was "sufficient charge" and even after that it took barely 5 days for the warning to pop up.
So for now, even if I am not using the car, I just start it for 5 - 10 mins every alternate day. But this is not a long term solution. The only long term solution I can think of is to sell this away once my lock-in on the mortgage is over which is 18 months.

Yes, happens to me constantly with a new g wagon. I trickle charge it overnight once a week and still frequent battery warnings. The longer I own my MB the less and less I like it. Another problem is the remote start. If you remote start it to warm it up, it automatically shuts off when you open the door
