Having purchased mine in March 2024 I complained for the first month to the Dealer and got nowhere, then by email every three weeks throughout last year to MB Customer Services. Most of the time I got a simply reply that they would look into it but never an acknowledgment or solution. As said it is a problem noted on many forums in other countries.
As I see it it’s not a design fault as it performs exactly as MB want it to.
There were probably only a few camera failures in the USA but MB lost the resulting lawsuit and were fined initially $15m and forced to pause all sales.
They did what most manufacturers would do and starting 2024 initiated a calibration check on every startup. I have no doubt that they are totally satisfied with the original camera software but were forced into a difficult situation.
The failure as I see it is a refusal by MB to inform customers or acknowledge worldwide complaints.
UK Dealers make it more frustrating by denying that they know anything about it and then offering a software update which solves nothing.
Having purchased a good many new Mercedes over the years they have lost my vote forever after having bought this one.
