‘21 C63s Transmission Malfunction - Car Wouldn’t Move








the tech implied there are known issues with this transmission but Merc official response is cannot duplicate or other vague response.
Curious if these trans symptoms are part of a bigger issue they are having difficulty sorting.




I took it back the dealer this morning. They gave me a loaner but likely won't have any answers until after Christmas. My car's been in the shop for a good 2 months out of the 16 months I've owned it for this transmission issue. And that's not including today's drop off which I'm guessing will be another 2 weeks if I'm lucky

My S/A called me this morning and said that since the last transmission malfunction code is a stored code and not an active one, they don't really have any way of diagnosing the problem until it happens again. They are wanting to know if I'll give them permission to install a data logger in my car so they'll know exactly what's causing it the next time it happens. I'm not sure I'm comfortable with a tracking device in my car, so I told them I needed some time before I give or don't give my consent on this. What do you guys think?

My S/A didn't provide me with the actual error code, I'll try to get that info from him tomorrow.

Apparently the data logger isn't a stocked item, so they're ordering it from Germany which will take another couple of days. I'll probably have my car back sometime next week and at that point I can finally get those bumper scratches repaired.

In the meantime, I dropped my car off at my body shop to get the bumper damages fixed, after which it’ll go to the tint shop to reinstall the front bumper PPF. I have less than 4.5k miles on the clock, it’s still under full warranty for the next 4.5 years so I’m hoping to finally get to enjoy my beast without any further issues 🙂.

Another week or so, and I’ll have the paint and PPF completed. I plan to take full advantage of the gorgeous spring weather that’s about to come our way, and finally let this shackled beast out of its cage!
