C63 Rattles, squeaks and other annoying noises
So.. after ordering my now Iridium Silver C63s AMG ED1 Coupe a few weeks back I started noticing comments by several users of these forums (and other related forums) about the build quality of the W205 C series AMG saloon. These users seem to have experienced multiple different rattles from the dash, suspension creaks, noises from the LED lighting caused by the Burmester sound system, door rattles and others. Some rattles seem to be weight related, temperature, most are intermittent but some constant, some over bumps. I've also seen some users claiming that Mercedes have suggested that their noises are "normal" for the C series! I've seen users saying that they have inadvertently recorded conversations from mechanics suggesting the sales guy lowers the customer's expectations!
Lets face it, a lot of people only come to forums to complain about something so some negative comments are quite normal but I have never seen as many complaints about a car I'm about to purchase as I have about this one and it is seriously putting me off.
From my own limited experience, before ordering I test drove an Edition 1 saloon and it just "happened" to have a rattle from the centre dashboard area. At the time I just put it down as a one off but now it feels pretty ominous! I was talking this over tonight with my youngest son who was sat in the back during the test drive and he mentioned that there were noises in the rear too.

Obviously I'm buying the coupe not the saloon. It is possible the coupe will be perfect, maybe Mercedes have sorted all the rattles, maybe the coupe is simply a different car. Maybe.
I'm sure many of us get fairly cold feet whilst waiting for a delivery but I'm on the edge of cancelling the order, I just do not need the hassle of rattles after purchasing a $120k car.
Are the any of you who drive on fairly poor roads (we have lots round here) that have not had any experience of problems with rattles, squeaks etc.?? Any feedback would be appreciated in either direction.




I get the occasional squeaks from the dash, I also faced the same problem in my E92 coupe and heard the same when I test drove the new M4/M3. It is for me however not as bad as some have made it out to be.
I currently have the sedan and am waiting for the coupe I've ordered. I can hands down say I don't regret it one bit. It's an exceptional car inside and out. After having it for almost a year, I still get a thrill when I jump inside... I haven't had that with any other cars I've owned.
Hope this helps mate!

Other than that, I don't notice many annoying rattles day to day. It's not completely rattle free but you do have to listen for any rattles and creaks which considering the type of car it is, I think is acceptable.
Worst thing for me at the moment is squealing brakes.

My greatest annoyance comes from the shelf behind the back seat. Teeth jarring when going over some bumps if there is the slightest slip of the wheels. A friend of mine that knows nothing about cars said, wow, it feels like the wheels are gonna fall off. Wow, this to describe a Benz.
Love the power, handling, design, fit and finish even seemed great but the build quality is pretty bad and it feels like the car is deteriorating at an accelerated rate. I come from a Jeep Grand Cherokee SRT. I beat that crap out of that Jeep and the only noises that ever developed came from speaker rattling at times with very heavy bass from specific songs. And this is after 25,000 miles. Not even at 1000 miles my Benz was already creaking and starting to become a rattle bucket. The other annoyances come from the random resetting of my driver preference settings and other personalization features such as the review mirror setting when in reverse. The keyless entry sometimes does not work at all and the trunk foot sensor worked three times, I don't even bother anymore.
To go to the extent of comparing a Jeep to a Benz when it comes to noise, vibration and harshness is mind-blogging to me. I have been put off by this Mercedes and I will not be getting another car from this brand again. Yes, my expectations were high, but they should have been. I paid a lot of money for this car. That is part of the value proposition from Mercedes to it's customers. I was already brand loyal but this car has put me off to the point where I have often thought, I miss my Jeep. Not only did it not have the sub-standard build quality but also, when looking at value to feature set, the Jeep had a ton more comfort features as standard. Again, I'm comparing a Jeep to a Benz, why am I even at this point?
Again, performance is amazing, handling fantastic but that enjoyment has been diminished by the build quality to the point where overall I am disappointed in my purchase and the brand altogether.

1.) Pre-facelift (PFL) cars, especially first MY's, are generally awful and inconsistent, quality-wise. Some folks might get lucky and get a PFL that has little to no issues, while some get one that is a total nightmare. It's a crapshoot. Not saying this to hurt anyone's feelings, but this is fact. Compare every PFL MB/AMG to every face-lifted (FL) MB/AMG in the past, and the difference/quality is visible. It takes 4 years for PFL to transition to FL; that's 4 years worth of data MB/AMG can leverage to upgrade/improve the FL versions.
2.) That said, though FL cars are generally better than PFL in terms of quality, it is again, not perfect. However, MOST major/minor issues PFL suffers from will have been resolved/addressed for the FL release. Think of it like a piece of software.
PFL = Beta Version
FL = Final Version
Naturally, issues from the PFL will be taken care of along the way, but they're going to be mostly patch work here and there. No extensive updates/upgrades will be available until the FL is released.
The Coupe may not suffer as much as the sedan, but I suspect the Coupe in PFL form will have its share of headaches.

I'm leaning more and more towards getting a new 911 instead.....because 911 build quality/residuals are far better than AMG's or M's.

. Residuals on 911s are good yes. However my 911 was an utter rattle fest. It isn't now but it was from new. Not just rattles, spoiler deployment failures (faulty compressor), speaker buzzes, trim falling off, trim poorly fitted, problems with the seals on the moon roof drying out and causing yet more rattles... the lot. I was told by more than one dealer that this is fairly normal. I drove several Caymans, 911s and Panameras at the time and since - whilst few were perfect not one was as bad as mine was originally. Thankfully Porsche did fix everything but it took awhile. It's one reason why I started this thread - not wanting that nightmare again!Having said all that - I love my 911.

I am coming to the conclusion that getting a rattle free car of almost any make is total luck. I test drove an X6M over the weekend (too heavy and fugly). Really loud rattling from the rear of the car. Test drove a Panamera a few weeks ago - minor but annoying dash rattle on rough road. M3 two weeks ago, creaking. C63 Ed1 saloon - rattles in rear and center console.
Golf - silent. Citroen work vans - silent (well nearly!). Wife's F-Type - silent.
Currently - well I'm going to stick with the C63 Coupe order and avoid walking under ladders.

It's interesting to me that we're in 2016, and we still have inconsistency with building rattle free cars.

Life is short, regardless if whether you buy a PFL or FL, these cars are going to depreciate fast. I've had my fair share of experience with CPO'd cars, and if you think a car like this will hold up well through the abuse of 1-2 owners, you are mistaken. High horsepower, turbocharged cars like this are going to be an out-of-warranty nightmare, and even those covered under CPO are going to be making frequent trips to the dealership for warranty repairs.
I've purchased almost all my cars used (with the exception of my first car), and every single one of them was a CPO nightmare (my CPO B5 S4 racked up $20k in warranty work alone, and my E92 335i was nearly 10k over the course of three years). I'm sick and tired of buying someones beat up trade-in that has already taken a depreciation hit, only to have to make multiple trips to the dealership when sensors and hardware starts failing. At this point in my life, I'd rather spend the extra money to buy new and have the latest model now -- and not deal with all the problems that come with pre-owned or used cars.
4 years is a lifetime in the auto industry... a lot can and will change.

@AlexZTuned I've purchased quite a few nearly new cars (and have not had many problems with them) but it's been awhile since I bought a longer term pre-owned car. You've put me off!
