Aug 27, 2025Backup camera & sensors

Started car, put in reverse, reverse camera did not engage, screen blacked out, I restarted car thinking systems and computers needed a re-boot. The backup camera no longer works. Coincidently, in reading the recall of the back-up camera on the 2019 C 300 Mercedes, this fits and checks all the boxes. I would like to get this fixed asap, my car has $63,000 miles, and no backup camera. The safety of this feature is remarkable, and cannot express how often I used it, I can see many things that I cannot see now. This problem has been confirmed by my mechanic. The dealership and MB USA has referred me here. The screen black out was the first and only warning I received before no longer able to engage camera, this happened in late Winter 2025. I am shocked that my VIN is not a part of the recall. Please add this so that I am able to use my back-up camera. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2019 Mercedes-benz C-class Phev verdict →
