2018 rain gutters

Just notice this.
Is it normal wear?
looks like paint is wearing of the plastic gutters from the rear and 1 side.
Is it under warranty?

That looks like a bad paint job. I would expect it to be warrantied under the bumper-to-bumper coverage. It is not wear, so if you take it in to the stealer be sure to express the problem as a defect and not wear.

Garage kept? Have you had it detailed? Maybe something got on it?

Now I need to go and look at mine.

Not sure the gutters are painted, its a piece of hard rubber I think. Looks like someone used a solvent of some sort and ate some of the coat.

Yes, garage kept. My service manager said, "This should not happen on a cheap 2017 car, let alone one that costs over $100K. But I still have to get approval for warrantee coverage. I'll call you tomorrow." Here is a pic...





I also showed him an area under the passenger side front windshield pillar where water drips down for hours after the car gets wet. It is getting rusty in the pattern that the water drips down. Luckily, it is not an area that people see, unless they are looking for it. Hopefully they will fix that too.

odd. my guess is either aggressive car wash chemicals, or aggressive car wash brushes that rub on the gutter surface and over time remove the factory coating. could be a combination of both.

Do you have pictures of the rust area? if it's by the corners of the windshield, it's a well known and common issue with these cars, even more so if you live in a humid and winter salt/deicing agent requirement climate.

If I go to a car wash, I only go to the hand wash, so they must be rubbing it pretty hard.

I don't have a picture of the rust area. There is a pillar in the front corners of the car that starts at the gutter, and ends behind the back of the hood. After a wash, or if it gets rained on, water continually leaks out of the bottom of the pillar. Luckily, the water leaks from the front part of the pillar, and not the side. It leaks down the crevice behind the back of the hood. There is a straight line of rust forming from the bottom of the pillar, downward, inside that crevice. Luckily, it can only be seen if you are looking inside the crevice.

And it is only on the passenger side. The driver's side pillar does not leak water and does not have any rust.

My 2017 G63 has the same gutter issues. I believe it’s from the automated car wash. I showed the dealer and they replaced them under warranty.

I take mine through a car wash and don't have this issue. Must be the chemicals?

I will start paying attention to this area.

So, I went back to pick up my car today. He told me that everything would be covered, and that in addition to the rain gutters and front pillar they are ordering me a whole new tailgate. I asked why.

He said, "We found more rust. In fact, that may even be the problem with the front pillar. It is not getting rusty. Rust filled water is dripping down that area and leaving rust residue on the paint."

So he had me stand on the rear bumper and look down at the top of the tailgate where there is a foot long line of rusted metal on top of the tailgate door.

I know, right? Just glad I have a year left on the warranty. And that I have an honest dealer who did a thorough inspection. I don't think I would have ever stood up there and checked that on my own.

It may be good to have them look closely under all the doors and also under the windshield seal. That amount of rust on the rear door is excessive/terminal even for an older truck.

The top of the rear door is a common rust spot on the G, although probably more severe in this particular case than one would expect given the age of the car. Check behind the windshield gasket as you’re probably developing significant rust there as well, and inspect the entire car and other doors very closely. It’s not unlikely that you’ll find other problem areas.

I have has customer's with similar issues - like 15's thru 18's - with my customers they usually use a premium car wash to keep their G's clean.

Replacing the pieces with fresh factory pieces WON'T prevent the problem from re-occurring.

Sure 3-4 yrs ago when this "issue" first started to come up - sure we went the "replace-the-trim-route" - and replacement trim develops the same problem for the same customers.

Frankly - the righteous solution that works - our Mercedes Certified Collision Center with our guys 15+ yrs experience want solutions that work - they pull the trim - sand and the trim with matching trim/bumper paint - and for us that has been the proven "right solution" on our side - and we do that for our customers No Charge.

It isn't a question of "is it under warranty or not" - if you have this "issue" the question is how to fix it so it doesn't happen again - and what works, works.

You guys know how to black out the rubber around the back window? It seems white and faded. Normal?
And just asking if your back door hinge rubber has that little crack in the middle? Seems like water could enter...

Those strips are aluminium and painted trim satin black.

We have had cases of "milky"/oxidized plastic trim.. we went thru testing on about 16-18 different products... this one stood out as the very best.. we also use it very effectively on VIP customer tires... a little dab goes a long way...

Rubber and black plastic trim it's the bomb..

How hard is it to replace? Do they just snap on or do I have to get dealer to replace them?
