You should definitely go for the service appointment to see what caused it. I had “Service required. Do Not Shift Gears.” in 5th day with GLB35. It happened after I shifted to rear gear after starting the car. After the car restart, everything was running fine. MB hot line recommended to tow the car to a dealership though it was running fine. It happened second time 11 months later. At that time MB had a transmission software update to fix the problem with auto parking brake release. So far it didn't repeat again. However MB took nearly 9-10 months to have the transmission update ready and I didn't even know about it until the second incident. Maybe a software update is needed for your problem. 2022 GLC loaner that I got at that time had a steering wheel vibration at the road joints, cracks, etc and MB service said there was an software update to fix it. I was surprised to see that at the end of life cycle of a model. Hopefully your problem will not happen again and MB can fix it quickly.
Yes that was surprisingly too, it was a common issue with the 2022 model year GLC specifically.
Good advice on asking for software updates though, in the case of that vibration although it sounded like an hardware issue, it was actually like you mentioned, software. https://mbworld.org/forums/glc-class...vibration.html
Yesterday my new Glc 300 4 matic gave me a critical low 12v battery issue. It said drive for 30-60 minutes or use a battery charger. I don’t understand why it was low, as we’ve taken two four hour drives and then three 3 hour dives over the last five days. The only thing I can think of is I was using a plug in cooler on these trips. Perhaps it drained the battery. Any thoughts are appreciated, I did charge the battery to 100%.
As per the guy who got a drained battery issue. This is kind of unrelated to the non start issue in that the cooler you were using probably was not the right amp power or working properly. But back to the non start issue, I was told, by a specialist, that long uninterrupted trips at a higher speed could prove helpful in keeping the battery up to snuff so that it can maintain the capability of starting the engine without the complications some folks are experiencing. Let’s see…..

Monitor the idle drain with a meter and start unplugging devices/accessories until the drain is at a minimal level. I mean, you shouldn't have to given it is a new car and a new battery, you only really needed to do that on older cars with weak batteries, times has changed I guess.

My20 SUV had a problem with the "starter" battery (vs. the 12v battery) a few days after I took delivery. The question is which battery is the problem?
I would drive at least 30 mins. and the next morning would get a low battery message, This went on for 2 months. Dealer said not to worry, it was normal. The cure was to go to the dealership and have them install a new battery. The low battery message never came back. I'm thinking you might need to have the battery replaced whichever battery is causing the message.

So sounds like a defective battery being the issue then? I wonder if it has to do with it being discharged for so long when sitting prior to being sold.
Our as well,
3 weeks old and and have the exact same issue three times already. I took to dealer on Saturday and dropped it off. They said they have at least one other GLC 300 with same problem and someone from corporate is coming in later this week. I love the car but if there is not a fix for this I'm not sure what we will do.
could it be that you are leaving the key in the vehicle or to near the car when parked? I was told that doing so can cause the vehicle to not "go to sleep" and runs battery down. My wife has a habit of leaving the key in the car when parking inside the garage at night.
Same problem here. The car will (usually) restart if you get out, lock it and wait until the logo on the dash goes off. The check engine light stays on, however. No confidence having my wife use it in situations where she could be stranded. Car is back at dealer 2 weeks after purchase, waiting to be looked at. I asked if there was a known control module problem and received no information. Anyone in the same situation should get a blank calendar and chart everything by date in case they have shipped a batch of lemons.

I had just picked up my 2022 S580 from the dealer, after they had it for several weeks. It had completely died in the middle of a busy highway. Anyway, I had driven to an appointment, parked the car and was walking along the sidewalk
when I saw a new GLC, that was marked saying it was a "Courtesy Car" from the local MB dealer, STALLED in the middle of traffic! Here's a photo. I keep hearing over and over how "ALL new cars have issues," but I think we all
buy MB vehicles, because we hope they are better engineered, better built and should be better TESTED, before they get into the hands of customers. Unfortunately, as of late, this does not seem to be the case.

I had my first issue driving home from the dealership. Cruise control and blind spot warning did not function. "Dirty Sensor" warning light. Car was just cleaned for delivery, so it's not dirty.

I have left my key inside My17,20 & now My23 SUVs every night parked in the garage. I have never had any of them “go to sleep”. I hang the key on steering wheel column. On the 2020 I hung it on the left side and the 23 it’s on the right side. Always starts.
Update: My car has been at the dealership for nine days now. They have no idea what is wrong and are hoping corporate can help. Meanwhile, I am afoot and having serious buyer’s remorse.
Mine has an issue with "dirty sensors" that prevents all of the safety equipment I wanted in a car, and had in my Subaru Outback for years, to be inoperable, and it happened on the drive hjome from the dealership, with a just-cleaned car.
The 9 days is obviously not encouraging. My wife's was picked up Monday and yesterday I was told a PTSS case was sent to Germany. I am assuming that means the dealer has no solution.

That is strange, that car doesn't even have the 48V mild hybrid system.

I'm being to feel I've made a huge mistake.

In that case, it could had been moisture in the sensor that needs time to air dry.

I can’t believe they didn’t offer a loner too. Especially if they don’t have any idea how long the repair will take.
The dealers in South Florida offer loaners if the car will only be in the shop a 1/2 a day. You have to make an appointment. But if you were to present this type of problem there are always cars available. Talk to the service manager and see what he can do for you. I got a set of weather tech floor mats a few years back. They came from a trade in but were in perfect condition. Couldn’t refuse.

Good luck
Exactly, I guess it also depends on dealerships but a loaner is definitely something they could least offer in this situation. If they don't have a loaner they should very least offer a rental but billed to the dealership.
I too am having the exact same issues with our 2023 GLC300 and have taken vehicle in to service center a few days ago. I was told Mercedes released a software update last night for the Powertrain control unit and they would attempt to install it today. I expect to pick up my car tomorrow. I'll update when I know more
