Maybe or maybe the one in the W206 is more prone to this type of damage hence the recall?
Thanks for posting this.

Mine will be delivered in Nov and it is a 2023 model. The above article says that production post June 2022 has the fix already implemented. Lucky me

do you have confirmation of the burmester missing from your build?
so far I have only the first printout from the dealership listing all the options I checked (included burmaster), nothing else.
Also do you have any pricing for the 2023 model?

I don’t have the 2023 price but it should be very similar to 2022. These days the additional markup that dealers put is more important than how the MSRP changes.

M-B determined that when the trunk lid is wet, opening the lid may cause water to drip into the trunk. Although that’s not a problem on most other vehicles, water in the trunk of the C-Class may reach the SAM
Since the tint is installed from the inside, how does this mess up the SAM....and not car washes?

A trunk lid does not get wet when installing tint, only rain and car washes

Not to get off topic, but had to comment…
I hope you only listen to talk radio… the speakers are the worst without the Burmester upgrade. I’ve replaced them all and it sounds good enough, but the standard speakers are paper and sound awful.

I also think they don't want to admit that they should had installed those covers in the first place when the previous models were susceptible and they were aware of it, it is a design flaw that took them this long to actually care about.

I would suggest you check on this with your local MB dealership before you do any window tinting. I wouldn't assume because your VIN # isn't on the list that you're in the clear.

I'd like to bump this thread for some reassurance to myself. I will be buying a 2023 C43 soon. Does this tinting issue still exist? I prefer not to tint at the dealer, but if I have to then I will 
I am located in the US.
Thanks!

it's not an issue - precaution should still be taken to reduce amount of water used on the rear glass.

I had the front done on my previous car but after replacing the windshield twice for rock chips and cracks, I decided it was too much money and hassle to get it redone. Consider that if you do a lot of highway driving.
My 2023 has the hud, I don’t even know if it’s possible to tint the windshield.
