You may have missed some of the thread updates as there have been two camera threads running - the other one relates to the A-Class camera.
The OP who started the software update story eventually came back and said he had been mislead, so a software update is a red herring.
My 2024 GLA suffers from this although I generally push it to the back of my mind.

@JCW36 I too tried to return mine a couple of weeks after purchase but both Dealer and MB Customer Services delayed, delayed, delayed and after 7 months or so, like others, I gave up.
Meanwhile I had scoured the worlds media and established that in 2022 MB were fined $15 million (I think they settled for $1.5m) in the USA because of widespread complaints by van drivers that the reversing camera occasionally didn’t work or froze. A child protection agency (can’t remember name) took it up and considered it a threat to children who might pass behind a vehicle. Litigation was in their name.
Mercedes Sales & Rentals were frozen until resolved.
Mercedes solution seems to have been to introduce the camera calibration that we are familiar with.
So it’s clearly NOT a fault.
Problem is I can’t see MB changing the procedure (unless they decide it doesn’t require such frequent calibration) unless they submit completely new software to whoever approves these things and are able to prove 100% reliability.
Seems to affect all models and classes with 360 deg camera and/or reversing camera so calibration on each startup has been the most cost effective solution for MB.
That knowledge doesn’t make me any happier but there you go!
