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 this issue on my 2023 low mileage GLC300. They said that when you turn the car off it performs a systems by cycling through all systems and then shutting down. In my case something was causing this check to run in an endless loop. This is what was draining the battery. They performed an “update” and verified that the car was shutting down properly. That was about 6 weeks ago and I haven’t had the problem since. Fingers crossed…
Give it about 6-8 months with the same style of driving. I thought they fixed mine too... 6 months later... same thing all over again... this has been going on since 2021... 4th battery was put two weeks ago and it's been back at the dealer for 1 week yesterday.
I have the same problem on my 2024. I don’t drive much. Not everyday. If I ever drive, maybe a couple of blocks. But even after I drive for 50miles, it still does it. This time, I did not get the battery partially charged warning, but went straight to critically low after we drove for 25 miles back and forth. I will call the dealer tomorrow and see if they can check the sensor and software.
I also had the check engine light even after I fist received the car. Every time I take it to the dealer, it doesn’t do it. The last software fix from the recall seemed to fix that one. So far haven’t had it since August last year.
I have another problem either driver side seat won’t go up sometimes. Once in a while, seat moves forward but will not go up. Haven’t had it recently but it is annoying as I’m short so I can’t really see the hood if I’m not sitting high…

Had the same issues as you did. Took it to the dealer 3 times to have it charged, so far. The last time, they indicated they reprogrammed some electrical items and it so far has not recurred. Last month the check engine light came on and indicated to stop vehicle immediately. Again it had something to do with the battery and they dI’d some further reprogramming and so far so good. I told them a larger alternator would fix the problem, but they would not commit to my statement. Hopefully Mercedes will acknowledge their problem and fix it. How many of us that are having problems would purchase another one? Not me.
How frustrating.
I stopped at the dealer yesterday. They said that the car has so many electrical stuff that if I don’t drive at least 20 mins per day, and if I let the car sit for 2 days, that’s too long and battery will drain. They told me to get battery tender and have it plug in if I don’t drive for 2 days.
I had this type of driving for long time. I had MB station wagon, GLE, Audi, BMW, Infinity prior to this one. None of the cars including other merceds didn’t do it. Unless it’s because they didn’t have as much electrical things.

Count me in.
Going through same battery issues and all kinds of other small issues on a GLC 300, 2024. Very frustrating and time consuming. First time Mercedes owner and not impressed. I have asked for refund and they keep updating the software...
My better problem may not be the actual battery problem. Only way to find out is to take it to dealer or one of auto parts shop and do the voltage test when I have the low battery warning. The reason I am thinking is that last time when this happened was after we drove for 50 miles. Gave me warning around 9pm. I started the car. This happened twice before going to sleep. Over night, nothing. Morning, nothing. Drove to a store. Then it happened. Took to the dealer but I was told to get the trickle charger. Then came home, nothing. Since then, nothing. If it was the actual low battery, I think by now, it would have been drained and dead.
I had the same issue with my 2023 GLC300. I drove for an hour to recharge the battery but that didn’t fix the issue. Dealer found that when the car is turned off a systems check loops around and then the car actually shuts down. In my case the systems check got stuck and repeated over and over again. This drained the 12V battery. They applied an update and it seems to have fixed the problem. It’s been over a month and the issue has not recurred.
Never sit i car listening to radio with engine off poof no entry on return Auxillary battery a disaster n mercedes me app delete,!if you pre heat seats the auxiliary battery goes 🇮🇪👍
This is exactly what's been happening with my vehicle. every 3days I'll get the Low-Batt alert if I didn't drive for at least 20 minutes straight. This has been going on since 2021 4 months after I bought it. When they replace the battery, it will last 6 to 8 months before this issue reappears. However, the last two batteries were replaced in January 2025 and the last one has now started failing, hence the low-battery message.
Alan0753 - there is a class-action lawsuit underway in Georgia. However, their case is centered around "sudden battery drain" meaning the battery suddenly drains while driving causing a safety issue. My opinion is that this is all related to the same problem. Those of us who are lucky that it hasn't drained while driving are just that... Lucky.
It would make sense for you to share a copy of that invoice with the Attorney handling that case as it will provide them with additional ammo to try to get all of our issues covered since they have my maintenance history and record of my reporting every 3-day issue and driving non-stop for 20 minutes or 20 miles. In my case, the dealer wrote that the customer doesn't drive enough. If they drive the car less than 10K miles per year that will damage the battery and void the warranty.
Contact them, send them your info, a brief history of the problem... They are very responsive.
There's another MB class-action suit listed on their main page regarding "Rusted subframe and Brake Lines" for anyone having those issues.
We ALL need to take action. These companies are ALL doing the same thing, cutting corners for higher prices, and bigger profits at our expense and frustration.
I know how crazy is that?
YES! Same answer from my Mercedes dealer. I've been trying to drive more trips per week, but just came back from a 4-day trip z(in another vehicle) and started getting the battery warning again. Didn't have this issue with my old Lexus hybrid
J'ai le même problème. Mercedes demande 13000€ pour changer la batterie et le calculateur. Le véhicule a 67.000km au compteur. Je suis aussi intéressé par le recours collectif.
