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?

My wife and i talked to a manger Thursday of last week we are waiting on a reply about lemon law or refund. This makes about the 5th day the car is in the shop. I think I am beyond 30 days in service for various reasons since new in about years time,which is part of the lemon law. With a car under 9k miles on it.
Disappointed
Count me in!
I have the same issue with my 2023 mercedes benz glc300 4matic.
That's a crazy statement to maintain the battery on the car.
I had the same issues multiple times and left me stranded multiple times which had to be towed. Not cool when you have a a car full of people after dinner.
After the second time I started fishing around for local California lemon law attorney s. The third time came around fairly quick and I put a request in to corporate to buy the car back which they promptly agreed to. So I left the lemon law attorneys out of it. Once Mercedes offers to buy the car back, you will go through the same process that a lemon law attorneys will go through. The real difference is the cost to Mercedes by having to pay the attorney fees..
I will say that coming into a Mercedes for the first time in my life, this was not a good experience.
The whole process from the offer to buy the car back through accepting a check and having them pay off the bank load took approximately 3 months.
They eventually replaced some module that was directly related to the starting of the car. I had multiple issues. The battery dying after multiple long trips was resolved with software updates but the constant sensors going off and not starting was another issue.
I will also say my car had 3,000 mi on it and it was in the dealership five times. It was a 24 GLC 300.
Good luck.

I belive it is still going on apparently. I have contacted the lawyers involved in order for my car to be included since I have the same issues as described in the lawsuit
I currently lease a 2023 GLC 300 MATIC PINNACLE my first Mercedes Benz and I have had several issues regarding no sound, fuse box replaced per recall, collision sensors warnings going off after a person walks past my the vehicle. Dealership did software update & occasionally I get low battery when vehicle is not driven for four days. Other than that, I'm glad I did not buy this vehicle.
Do you have to live in Georgia for your car to be included? Mine is a 2024 and within a few weeks after purchase, I began having the 12v issues. It has now been with the dealership since July 5th with one program update but continues to get 12v message.

No, it's a federal suit filed in federal court.
My 2024 GLC bought in Nov 2023 had the same issue. The dealer looked at it and said everything was fine. I suspect it is caused by some kind of faulty software which Mercedes has not yet discovered. Whenever this battery warning occurs, I can hear some humming noise under the hood on the driver side every 2-3 minutes. I somehow found this "work-around" by accident and it seems to work for me. Always lock the car with the key fob "close by" the car for a few seconds. If I lock the car from a distance and the key fob is not close by, the noise would start as if it is looking for something to complete the locking process and within 2-3 hours , I will get a low battery warning message. Give this a try in the interim before Mercedes is able to provide a permanent fix.

The fix is a new fully charged battery. It's not a mild hybrid, electrical, or software issue. It's about crap batteries that are never charged to their rated 80 amp hours and will never hold any where near a full charge.
My battery was at 20% of it's 80 ah rating after 40 mile drive home from purchase. I put it on a .3 ah trickle charger hoping it would top off but after 2 days I realized I needed more amperage to drive a charge through the AGM battery. I then increased the charge to 6 amps and after 30 hours I got the charge to 60% of the rated 80 ah.
I decided to drive it a month or two and recheck it. Guess what? just as expected, after sitting for 24 hours the battery is right back at 20%.
I believe if dealers checked these batteries "cold" after sitting for 48 hours they would find most of these batteries need replacement. As long as they check them within a couple of hours after being driven for more than 15-20 minutes they will continue to tell owners that the batteries are fine because the batteries have enough cold cranking amps to start the cars. It's "catch 22" stupidity at it's worst. Mercedes has to fully understand the situation but like most manufacturers they refus to admit or fix.
As I said in an earlier post...the battery supplier adds the acid which should get the batteries to at least 60% of rated AHs without fully charging them to the rated 80 ah which adds cost and time. The longer they go without being fully charged, the less charge they will ever be able to hold. Then the batteries go to the factory and sit for who knows how long since they were prepped. Then they go in a build and are started a couple of times over the next month or more before finally arriving at the dealerships who don't fully charge them and then we end up with new 80 ah batteries that can't hold a fraction of their rated charge.
I haven't decided yet just how I'm going to deal with this before it starts causing electronic issues in my car. I'll probably present my recorded measurements to the dealer and ask once for a new battery and tell them nicely that my next words will be a demand for a new battery with additional actions as necessary. If they refuse, I'll tell them I'm buying a new battery, filiing a complaint with the BBB, state Attorney General, and never doing business with them again. Then I will do all of those things.

I received 11 notices in 6 months. Then after driving 200 miles in 2 days - the following day the battery was dead and I could not start the car. The dealer service person told me I wasn’t driving the car enough -34,000 miles on the car but according to him I was not driving the car enough. Don’t be surprised when your car won’t start because the battery is dead. Unbelievable!! One dealer said “it happens all the time - what are you complaining about?” Really?
I’m trying that, the noise has stopped and I haven’t gotten the low battery warning yet. It’s only been several days. In the meantime I bought a trickle charger just in case. Dealer told me to go for long rides to prevent this from happening. Ridiculous!
I received my GLC300 coup in Dec, 2023. It was built the end of Nov 2023. I had the starter battery problem. The technician at my dealer finally fixed it. He said that during production the overspray affected the ground wire. He cleaned it and they replaced the battery and I have had no further problems at all with the car to date which is Nov 1. It seems this must have been a quality assurance issue at the mfg site. I hope this helps others with the issue.
