We had a number of issues with out 2018 top. We are not the original owners. All repaired under MB factory warranty. We were told by our service advisor that MB offered an extension of the factory warranty for 3 years@ $3,000.00. We purchased it 3/22. Had another top issue which was covered. Was told that if it had been CPO warranty it would have not been covered.
Point is, if you have the opportunity to purchase the extension in lieu of the CPO it is probably worth it.

Yes, I agree, but the next line in the CPO warranty book reads something to the effect "mechanical and sensors..."

Personally, I feel it's either that or a defect, which is also listed as being covered.

Update:

Mercedes came back and offered 75% coverage for the issues with strings and rear window resolution. My final cost would be nearly $4k.
Over the past few days, I have spoken to a few local Vert top specialist who are confident they can epoxy the window in place if the progression has been caught in time. Apparently the canvas shrinks as it ages in the sun and pulls away from window. Both blamed the OEM top material as the issue.

Aftermarket tops that both claim they have used for decades are coming in at a cost of ~$4k to install for the E400 and the tops come with lifetime warranty. MB OEM replacement comes with a 12 month warranty for comparison.

So in the end, MB will repair the strings issue, cover 75% of costs and I will see if the aftermarket guys can epoxy the rear window in place.

Does anybody know if the S class Cabriolet has the same architecture in its roof. Rather than face what seems to be inevitable failure we will consider selling our E400 at the end of the warranty in 3/24.

I want to assure you that the strings breaking a fraying ARE covered by the CPO warranty if in good standing. There are a few forum members including myself that have it repaired under CPO warranty. If the frayed/broken strings won't fold the headliner properly then there is a problem and if that will fix the latch concern then you're 100% covered. My suggestion is find another dealer. The back glass is a totally different issue and requires a whole new top which includes rear window glass and is not covered. Get the strings fixed and see what happens.

It seems like all of the MB cabriolets have the same defective rear window attachment. My top guy says between 4&5K to replace it with a German made top with a better window design IMO this is a defect in material and workmanship that should be covered. I spoke with MB customer care and asked for a courtesy replacement under my CPO and then the additional 2 years that I purchased. They conveniently came back with they had already done a courtesy replacement of the bluetooth antennae (a $240 job) to fix another problem and they can only do one courtesy repair. Well that repair that was suggested by the dealer did not fix the problem so realistically that repair doesn't count in my opinion. This problem exits across the entire MB /Cabriolet lineup.

Just a word of caution: I would NOT have Safelite or any third party install glass in my car. They use cheap Chinese windshields that are not up to M-B spec. When my C-Class coupe's windshield cracked, insurance would only pay up to $500 to replace on my comprehensive coverage. I took my car to the dealer and paid the additional $1000 to have a factory windshield with the factory "Mercedes" script in the lower right-hand corner installed. I was told that when trading in your car, you'll get less value for it if it doesn't have the factory windshield (not to mention one that is lower quality).

One of the things that I opted for when I purchased my E-Class was windshield replacement coverage. It's my understanding that replacing a new E-Class windshield in around $4000.

Just got a 2018 E400 from CarMax with the extended warranty. I’m taking it back in a couple of weeks to see if they will cover it.
Has anyone managed to get this fixed by a third party without replacing the whole top?
