Hi, I am new here and i have a new c450... coming from an e90 m3.
I noticed that the flaps/covers for the roof rack appear to be discolored i.e. not uniform black in color. Will post pictures later but to me it looks faded. Anyone else have this issue?
Also noticed the rear spoiler not completely stuck down on edges and rear bumper right hand side where it meets light cluster not completely flush like the left hand side. I read about the rear bumper alignment but this is the right hand side.
Will take all of this to dealer to checkout but looking for feedback.
I don't have discolored flaps but I had the same issues with the rear spoiler lifting on the edges and the right taillight stood a few mm's proud of the bumper. There just isn't much footprint on that spoiler to stick down. The light and bumper alignment is just sloppy assembly. The bumper can float a few mm at each seam when assembled. If they are careful they can get it perfect, if not, it lands where it lands. My windshield was also glued in crooked. 1mm gap on one side, 3-4mm on the other.
My dealer removed the spoiler, cleaned off tape, and re-applied with new tape. New tape is actually thinner and the spoiler has close to zero gap to the body now. Initial response on the light and bumper alignment was it's within assembly tolerance. I asked how the tolerance was specified, without an answer, they were able to greatly improve it. I didn't push the windshield alignment, too much to go wrong.

The windshield mis-alignment is a bit of a surprise. In the C class assembly videos I've seen, the windshield is installed by a robot, so one would expect fairly tight tolerances.
If you haven't seen it, search it up on YouTube - "Mercedes Benz C Class Production". It's pretty neat to see. Robots are used for welding up the body, painting, windshield installation, and main dashboard installation.

You should worry, reading the VW Golf R forum recently (that car is more expensive than the average C class) someone was complaining that their new car arrived with missing build features and one interior door panel red and the other three white!

Thank you. I checked a few other cars at the dealership and they all look similar regarding the side of the bumper. Right hand side stick out a little. Car book in on the 9th to get checked out.

Indeed but sadly the robots are programmed and mainteained bu humans..
Also the robot can be fine, the vehicle position and window frame tolerance stack up can impact perceived screen alignment..
eg robot datums off one side of screen apeture but appeture is out of tolerance.. screen is in the "right place" body surrounding it.. appears not..
(i lost many hours of my life programming screen butyl application and fit robots amongst others.. so many external variable simpact the end result.. )

All the best...
Good points Shadwell. Then I guess it all comes down to QC and final inspection. These problems should have been caught and fixed.
Re: the roof rack anchor cover flaps, sounds like a warranty issue, they shouldn't be fading so soon. The flaps on my 4 yr old black C350 still match the adjacent painted areas exactly.

This is the worst one. Car has less than 300 miles on it
So you think the fading and oxidation of the black finishes has something to do with lazy assembly work of fat people?
Read the entire thread
OP said "Also noticed the rear spoiler not completely stuck down on edges and rear bumper right hand side where it meets light cluster not completely flush like the left hand side. I read about the rear bumper alignment but this is the right hand side."
Yes, I think fat lazy people has something to do with fading. They didn't make the black finish properly.
Did you get offended?? LOL
