Mercedes Benz C-class W205 Problems Malfunction What Is Your Experience ?
I bought the car in Jan 2015 so I only have 1500km on the clock.
The car developed a dangerous flat spot.The car will experiences problems when taking off from a stop street,going around a bend or overtaking.The car battles to get up to speed but all of a sudden takes off.
I took the car to a dealer and apparently the car needs a program to be installed into the computer system.This program has not been written yet and will probably be ready only in April.
So the car cannot be driven till this program has been installed which may only be in April.
I have tried to contact some senior people at Merc Headoffice but to no joy.
The switchboards refuses to transfer you to anyone that is senior ,you are forwarded to the call centre.It is now 2 weeks and I have received no feedback.
I have since discovered that the are about 7 cars parked off with the similar problem at my local dealership.All brand new vehicles.
I will appreciate any advise as to how I should progress with this this matter.
I paid R600 000 on this vehicle and I used my life savings as a deposit.
This is my 4th Merc but it will definitely be my last.The quality of the Merc product is not the same as 10 years ago.

If you have no joy, ~ report it to the Motor Industry Ombuds.
If this is a known problem waiting on Germany they must give you a loaner & quarantine your car on safety grounds.
Hint ~ the service manager of Sandown Motors Sandton (subsidiary of MBSA) is a real can-do chap. He sorted the brake pedal going to the floor on some W204's that other dealers said was NORMAL!. He took this forum's advice to look at the ABS block & replace it. Problem fixed.

I know all the arguments about this being a biased sample because forums like this are not a true sampling of all owners, but it's still a ridiculously high number. If anything, the actual numbers are likely worse, since some who reported no problems initially have now experienced at least some sort of an issue with the car.
I was just reading the latest issue of Consumer Reports and they mentioned that they monitor online automotive forums as an indication of how particular cars are faring in the real world. This arguably being the most active W205 forum around right now, it's a safe bet that they are keenly aware of all the issues plaguing a car they have already lauded as a leader in its class. For all the honors and praise this car has garnered in the world press, and from its owners, I think MB has really shot itself in the foot by having such poor quality oversight, particularly at its US facility. At some point, this will all catch up to MB and bite them big time.
My C300 will be gone for nearly three weeks before I get it back. A number of issues, including the MB-Tex fiasco, will have been addressed and I was promised a perfect car when it comes back. One more extended service stay after this and I'll be in that 30 cumulative day Lemon Law window ... but I hope that never happens and all the demons have finally been exorcised. It's such a great car ... too bad it's taking MB so long to figure out how to build it.

My opinion is that this is a particularly troublesome first year introduction. I do think this thread is a realistic representation of owner problems, but that's just my opinion. Until we see some empirical data, we really won't know.
The sound does not always exist, but most of the time it does, especially on the passenger side. Very irritating. Perhaps i need to take it to the dealer. Anyone else experienced this?

I have noticed something on my C300 quite a few times in the 3 months I have owned it. I am at a stop light or stop sign. When I try to go it feels like something is still pressing the brake pedal. I give it more gas to get it to go and all of a sudden it "lurches" ahead like the brake released. My wife looks at me like I'm an idiot when it happens. Honestly, I do not have an answer for her why her head just hit the headrest when it does happen. I hate to say "it's the expensive new car....it really is....it's not me. I'm not the idiot - the car is".
Anyway, I have a tendency to use my left foot on the brake sometimes (I know!) so the first few times it happened I questioned whether or not I actually had my left foot on the brake and trying to press the gas pedal with the right???? Well, I know for a fact on a few of the occasions it happened I was using my right foot on the brakes and did not have the brake pedal depressed but still experienced the lurch.

I have to check this out although i think i heard the same sound a month ago when i first got the car and my friend was test driving it.

-- Roof trim molding was deformed, replaced by dealer;
-- Touchpad was defective, replaced by dealer;
-- '4Matic' lettering was loose, replaced by dealer;
-- Trunk needed to be slammed to close, dealer adjusted;
-- Steering column inspection recall;
-- Bleeding seats, waiting on parts to replace.
-- Sagging sunshade, dealer re-lubed and said there was no further adjustment.
I also have the tail light/bumper fitment issue which I need to address, and excessive wind noise from the driver side window.
I was actually surprised to read that this was considered a quiet car. Unfortunately I test drove a different vehicle from the one I ended up purchasing and even then didn't have an opportunity to test drive it on an interstate. I really noticed the difference when I had a GLK loaner and it was vault-like by comparison.
Honeymoon was over pretty fast.

I joined this site so I could find out anything I needed to know about my car that maybe wasn't shown to me when I picked the car up. And also in case someone is thinking about buying one, they can ask what I think of the options.
One thing I have found that the dealer didn't show me is that when you unlock the car with the key, keep holding the unlock button down opens the sunroof and all the windows. Great for when you’re heading to the car with shopping so you can let the heat out of the car before you get there.
Also I have a yellow light that is constantly lit up on my console that says ‘passenger airbag’ wondering why that’s there?
Cheers
