Every time I start my new Mercedes, the backup camera MUST recalibrate itself even if I never put the vehicle in reverse and am driving forward. This happens throughout the entire drive, every single time. The Mercedes forums all corroborate this as other models; not just the GLB, experience this. Mercedes denies anything is wrong and says this is “expected behavior for rear camera calibration”. This makes absolutely no sense why a rear camera would need to recalibrate itself on every drive even when you never place the car in reverse. Furthermore, the backup camera is the “pop out kind” so you constantly hear it popping out and popping back in. It’s extremely distracting as it continues to pop in and out as I slow in traffic at a signal or stop sign. This is with certainty, a manufacturing defect and must be remediated. Thanks for listening as it’s appreciated.

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 2024 Mercedes-benz GLB verdict →
