2023 GLC will not start
#226
Well mine is back in the shop again for the 4th time with issues related to the automatic driver assistance system. Doesn't notice cars next to me, lanes, markings, etc. No errors this time except for the check engine light keeps coming on every 2-3 days. I contacted an attorney today who took the case, and they will send a demand letter in the next 7-10 days to Mercedes. Anyone been through this process and know what to expect now that I have an attorney involved? When I tried to handle myself, MBUSA refused buyback request and said they have no reason to provide any compensation as I was provided a loaner
Any insight appreciated.

That's your ONLY option to not get screwed over. Trust me that’s it.
been dealing with this bull**** since April my car has been in the shop over 90 days straight and Mercedes still doesn’t think that’s wrong

Has your attorney been able to make any progress with them? I've read that they can be very difficult sometimes leading up to going to court where they lose most of the cases, but they do it to delay... seems more costly IMO

I would think locking would drain more since the tow away protection and interior motion sensor are both on. I’m sure they changed the canbus behavior for the new model but my 2021 c43 stays fine unlocked in the garage, haven’t had a single issue with the car 2 years later

I had mine locked for 2 days parked on a steep incline driveway. It drained the battery, I believe because it fooled the tow-away alarm. After parking level for 2 weeks, no issues. I returned to the steep driveway and it again showed battery critical.

If you store your vehicle in your garage overnight, turn on standby mode (unless that is no longer a thing?) as it also disables anti-theft so don't turn it on if the vehicle isn't in a secured space.

Picked up my ordered 2023 GLC about six weeks ago. Put 3000 miles on it with no problems whatsoever. Then it sat in my garage for about three weeks (I was out of town). A few days ago I received an automatically generated email from Mercedes Me Connect telling me my battery charge status was “critical” and to drive the car for 30 to 60 minutes or connect a battery charger. So I drove it. Everything OK. Looking into this I discovered that the car is using its 12 V battery just by sitting, whether on the dealer’s lot or in your garage. Maybe it is connected to online services, alarm system, 360 degree feature or whatever. A low battery can cause all kinds of problems. If you know the car is going to sit for ”extended periods of non-operation” (Mercedes manual) you should turn on the “standby mode” found in the multimedia system under settings>vehicle>open/close. This is reviewed on page 190 in the 2023 GLC manual. Also, it will tell you how many weeks it is good for when you turn this on. Best to do this when you have a full/normal charge level to start with. Hope this helps.

But MBs are failed heaps of rubbish in the practical execution. MB's circus of clowns (dealers) add no value to the equation and are rather instead parasitic to both the parent MB AG and consumers.

I can certainly understand the immense frustration that some owners of the 2023 GLC are feeling, I was happy to cancel my order and opt for the old, tired looking, however, tried and true 2022 GLC. We have had 7 MBs over the years and 2 BMWs . German cars seem more complicated and the German manufacturers will introduce more advanced technology before their Japanese counterparts do. Simply stated the buyers of the first MY of a totally redesigned car become the lab rats. I luckily have had no major issues with any of my current 3 MBs or any of my previous ones. Saying that they are all a piece of crap is not really accurate. Some of them certainly are a piece of garbage, however, some are worthy of the MB reputation of a luxury brand building beautiful and safe vehicles. Statistics can be interpreted any way that suits the person quoting them. The Japanese vehicle, Lexus for example, is a more reliable vehicle, the fit and finish is better than the MB, the resale value is higher, and importantly, Lexus is far ahead in how they treat their customers. This is not only at the dealership level, it is at the corporate level as well.
That being said, we still buy the Mercedes. We may showroom shop for a Lexus, test drive it, even get some preliminary pricing, however, there is something lacking, perhaps the WOW factor. Maybe we are foolishly brainwashed by the Mercedes name and can’t make a logical decision, maybe we don’t really like the look of the Lexus, especially the front grill, maybe it’s just boring, who knows. In any case I do feel very badly for the owner’s of the new GLC, who missed out on the fun and excitement of getting a new car. As recommended, the only way you’ll be heard by MB is to get a lawyer. MB strategy is to ignore and perhaps you will give up. GOOD LUCK.

Josh - somewhat similar situation here. Tried the dealer (several times), NHTSA, customer care. I just got back from the post office where I sent sent a certified lemon law letter. It’s a waste of my time and their time to take it to the shop. They hook it up, say nothing found, and send me on my way. Luckily, I have many videos of the behavior.
Best of luck & please keep us posted.

I did the same thing. Started taking photos of the lights and videos of the driver system not recognizing cars that were next to me with zero blind spot detection or car displayed on the driver assist display. Lawyer said 7-10 days to send demand letter. I’ll keep you updated on how it goes.

The bugs will get worked out; I'm hoping for the 2024 model when the gremlins disappear. I've heard the ride is amazing and quiet and those are my two first desires, and the on-center feel of a German car is my 3rd like. It's hard to change brands. I'm not trading my C350, I'll keep it, love it, special ordered the Advanced Handling Package, the 5 months wait almost made me crazy.
Had one digital light error message. The lights were operational all the time. The only thing needed was a minor software update so the software could communicate with dynamic lights. While at the dealership for the update I got a Mercedes Me message for the 12volt battery. Took it home (dealer 10 minutes away)and 12v message reappeared the next morning. Drove the car for an hour or so doing some errands and message has not returned. Guess I’m one of the “happy” owner/leasee.

so my car is STILL in the shop. Been there 5 months total now. Purchased in April. Drove it maybe 4 weeks total. they STILL cannot fix it and I just laid into the guy today because I'm sick of waiting and he showed me his shop they have TWENTY ****ING FOUR 2023 GLC300s in there right now--ALL busted. My city only has a total population of less than 300k, so pretty much every 2023 GLC300 is probably in there right now. This car has a serious design flaw. This is crazy. I have put almost 10,000 miles on their brand new loaner. How does any of this make any sense financially for any party? Me, MB or the dealer to just have my car sit there for 5 months and have me totally devalue their brand new loaner? Screw Mercedes, never buying their crap again.

Are they replacing the whole PTCM? Did they tell you why?
I'm wondering why they didn't try first with the SW update

Hello all,
I’m having the same problems as many of you, except I have a 2022 GLC 300 X253. I’ve browsed that forum as well. I found this thread first when I was googling the error messages I was getting.
My car has been at the service center 3 times within 5 weeks, for the same issues: brake spot assist inoperative, active brake assist functions limited, ESP inoperative. The check engine light and “ESP off” light also appear, then the car goes into limp mode. I’ve been stranded 3 times now.
The last time it stranded me, I was chatting with the tow truck driver and he said he had picked up about 6 or 7 other 300s for the same issues throughout the week.
So far my service center has given the following solutions:
1st repair attempt: software update and fixed pins in steering wheel
2nd repair attempt: replaced throttle valve
3rd repair attempt: replaced control unit
Each time they claimed it was “fixed”. It has spent a total of 22 days at the service center. At this point (in my state), I am one repair attempt away and/or 8 more days in service away from being a certified lemon.
It’s unfortunate, because I do love my car but I have lost all faith in its reliability. It’s become a real headache.

^sorry to learn abou this^. Hopefully you can exit this vehicle and into one that is more reliable. Mercedes is bottom of the barrel quality and reliability, unfortunately for its customers, shareholders and employees.

MBWorld Fanatic!
I have a 2020 GLS450 in the shop for defective MbTex issues. 2023 GLC as the loaner. 1,200 miles, and it crapped out this morning when I came out of Dunkin Donuts and tried to start it. Countless errors from turn signal to transmission popping up.
First time in my life (50) that I have been stranded.
I can’t think of a manufacturer these days that is as bad as MB has become now. I’ve had the GLS since new and has been decent, and have owned my 2014 E350 since 2017 as a CPO and has been marginal (but suspect hard first owner).
after this glc experience this morning, I will not consider another MB vehicle ever again. Just glad it wasn’t actually mine.
