Common Problems with the C63 AMG
1/ Sqeaky sunroof when in tilt mode as mentioned above.
2/ Small Fuel tank, as a daily driver I struggle to go 3 days with out filling up.
Whoever in AMG decided to put this fuel tank with a 6.2 L+ V8 must surely be looking for new job!
Cheers, Pickles.
1. Oil Pan Leak (within first month of ownership)
2. Coolant Level (too low)
3. Engine eating oil (still not sure what that was due to)
4. Ticking/Knocking noises from the engine (cams related issue)
5. Transmission re-set (4-5 times now)
6. Torque convert re-set (Twice)
7. Transmission oil (Levels were too low)
8. Pressure regulating valve (Replaced due to whining noises)
9. Battery Replaced (once)
10. Wipers (replaced once due to plastic parts breaking off in 11K miles)

"Soft" windshields
Body panels or seams not flush and crisp, metal to plastic
Had one instance where the steering wheel was stuck for a day and would not move down
Another time the navi screen would not open one random day
"soft" leather that cannot take a slight bruising
squeaky side mirrors and plastic housing

rear view camera sucks
Not the greatest paint job with some imperfections and drips
I guess the power, torque and engine growl makes up for some of this...
It doesnt always happen. Its hard to isolate exactly where its coming from. Maybe the passenger seat, maybe further back. And I cant tell if its from near the sunroof or near the rear window.
Ive tried moving the passenger seat to many different positions with no luck.
Ive tried pasenger headrest up/down/midway.
Ive tried panorama roof open, midway, closed. Ive tried panorama shade open, closed, midway, etc.
Im going to try rear seats down tonight when I head home from work.
If that doesnt isolate it, Ill start stuffing rags and towels all over the place until I find something that fixes it.

My previous C63 Sedan had the rear sunshade, and it squeaked a little from time to time, but nothing annoying.
The rattle/squeak from the back of my new one is MUCH more annoying than that
And they will not go away, one suppressed and another pops out.
I think MB really need to redesign the way they put the interior parts together. At least consider putting proper amount of felt tapes in between to reduce this kind of annoying rattling noise.

Another thing is that my front brakes started squeaking.
Anybody here who had these issues resolved and wouldn’t mind sharing some info? It would be very much appreciated!!

Minor squeaks and rattles are a way of life for these kinds of cars, anything with a suspension this stiff being driven on bad roads (like SoCal, where I live).
I can deal with the plastic trim squeaks ... I'm used to it.
But the sound I'm having sounds like a screw or washer came off, and is rattling/banging around against metal somewhere. Its probably behind an interior panel, and me (or the dealer) will have to find which one, remove it and find it.

Today going to lunch from work, I shoved one under this plastic bracket beneath the passenger seat, which is loose and can bounce about. Seems to have made a difference. Ill give this a day and see how well it helps.
If the problem persists, Ill head to the dealer.

I am going to further dig into it but it seems we all have the same issues
I love the car but come on 40 miles and rattles already?
