Iv had the car for a week now its been back to the dealer for some minor things wheel aliment and some plastic trim in the trunk and now this.
THIS HAS PISST ME OFF, has anyone come across this, easy fix?

ABS and traction control I have had before on my g63. it was a software issue that they were able to fix very quickly. I don't know that your issue is the same as mine but that's what fixed mine.

The lane keep inoperative, when the warning came up, was it raining by any chance? in a bunch of other MB's, i have seen that warning come up when it was raining pretty hard but usually the blind spot monitoring would also say it was unavailable.

I would assume its a software issue. Get used to it. You got the first year of a new generation of car. I would not expect anything less.

Agreed 100% with this.

**** like this is why I prefer waiting for mid-cycle facelifted MY's.

It actually happens on my 507. I don't know what triggers it, but it seems random. All the systems shut down and I have to restart the car. The dealer told me is was some backup battery at first but then they told me the 507 doesn't have the backup battery and needed some kind of reset. It still happens occasionally.

Yes, mine (may delivery, 5800km) is doing this intermittently now...which I really don't care about. The one that bothers me is that at the same time that i get the lane keep warning, I get warning about inoperative presafe....the reason I apparently burned 3k....and the miserable transmission (at least 3 times it bogged down when I needed to move fast from slowing down) is a nice cherry on top...., my 3rd c63 now but I think I'll give the ctsv a shot next...can't be worse!

+2 !!!!


This whole issues thing with these initial production batch of vehicles is becoming a bit of a joke with this new W205 series unfortunately


I suppose it depends on individual circumstances but speaking for myself wanting to buy outright and own for long term, I'm definitely hanging off until the tail end of the model series run, for most people who lease and then move on or update or whatever I suppose it's something you can deal and live with


I believe production batches built and supplied from Germany have so far proved to be much better, which is a welcoming thought for people outside of the U.S.


Apologies to the OP for the stray off topic, I hope it all gets fixed with minimal hassles.
