19 G550 problems already, anyone else? Happened in old models?
- Active Lane Keeping Assist Inoperative
- <Traction control symbol> Inoperative See Operator's Manual
- Active Distance Assist Inoperative
- Active Brake Assist Functions Limited See Operator's Manual
- Blind Spot Assist Inoperative
- Also from time to time the Automatic high beams functions turn off
Any ideas could be the culprit or if anyone else has had these issues on their 19 or previous models even of any Mercedes vehicles?
My thinking is it could be a problem with the blind spot sensors causing everything to turn off.
Thank you!

So sorry you are experiencing this on an all new model. These kinds of things, can plague a new model....any brand (not unique to Mercedes).

Yes - these systems are "linked" thru the shared sensor systems - in if the fault codes were triggered on-the-rod - would be best if you could share what/where you were when they mass-triggered - or if they were triggered on start-up (from what little has been said - I don't "think" so).
On diagnostic - in this case - your dealer tech's under MB's direction have to work thru diagnostic protocols - step by step - each step uploads to MB - then they have to wait for MB response to go to next step - patience and understanding are keys here..

My dealer had put over 100 miles on the vehicle this week doing road tests including 1 over night road test and I believe they asked for another yesterday, I'm going to visit them today and demand no more over night road tests are done on a 4 week old vehicle as they're racking up my miles and not getting anywhere.
I've drilled them and asked if it's radar sensor related and they stated no that they've fully checked the system for that.
I had no error messages or the like, however...
It appears that I'm the only owner who received such a notice from MBUSA? I expected to see more '17 G63 owners to respond to this thread...
Cheers/BB
