Found this online today - appears there's a recent recall that might address this issue. On the nhtsa.gov website, look for campaign #22V678000, "Short Circuit from Moisture Accumulation in Trunk." Copied some of the information below. Just passing this on.
An electrical short circuit in the SAM could lead to various malfunctions, such as rear exterior lighting failure, unintentional rear seat folding, and rearview camera failure increasing the risk of a crash or injury. In addition, al electrical short circuit might increase the risk of a fire.

Which is strange because the previous gen vehicles also have this issue apparently (just learned) although never experienced personally: https://mbworld.org/forums/e-class-w...ml#post8635652. Unless there was a SB for the previous models as well that I am just not aware of?
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

giovane

Do you mind me asking when you placed the order? I ordered mine in August and I wonder when it will be delivered

zz2017

Not at all. I placed it in May of this year. In theory it is being produced in Oct and there my Nov delivery date estimate.

I won’t get the SAM issue but I wont get Burmester either…

giovane

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?

zz2017

i have confirmation given that I don’t see it in the build order. You need to check the actual build printout from Netstar. Your dealership can provide that. It is very likely you won’t get burmester either. Sorry.

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?

GMF

Have you gotten the car tinted ?

I just got mine delivered in Sept 2022.

I don't see the recall against my vehicles VIN. Wondering if this issue is fully fixed now for me to proceed with the tinting

W205C43PFL

It is because water can leak from the interior side of the rear glass into the trunk via various pathways.

Steely

I am aware of that but MB recall does not address or admit it. It is strictly about "when the trunk lid is wet, opening the lid may cause water to drip into the trunk"
A trunk lid does not get wet when installing tint, only rain and car washes

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.

giovane

Could you share info on the upgrades?

W205C43PFL

Ya I see what you mean, not everyone tints their vehicles though so if they state the trunk lid may cause water to drip into the trunk the urgency of getting it fixed might be higher? I mean it rains in many countries, some more frequent than others, so...

W205C43PFL

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.

zz2017

yes, please. Would love to know what you did and how much it cost, if you don’t mind.

shadi150

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!

iTrader: (1)

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

shadi150

Great, thank you

giovane

Confirmed. Done the ceramic window film on my '23 no problem

eatmydust

Anyone get the front done? Any issues?

giovane

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.

W205C43PFL

It does allow a lot of heat in though but I think some states are illegal to tint that. Another way to reduce heat is also tint the sunroof I guess.

giovane

True. That’s why I keep a sunshade in the trunk.
I did tint the sunroof as well, it helps.
