More complaints about the GLA reversing camera on a Facebook page over the weekend so I set about updating my background knowledge via Google and was stunned to read of so many (big $) fines against Mercedes in the USA.
No wonder that cars cost so much if they are paying off big $ fines for things like wiper failure, and recall procedure.
The camera issue seems to revolve around newish legislation as follows (2 articles):

Demystifying NHTSA FMVSS 111: Unveiling the Backup Camera Revolution

Ensuring a clear view behind your vehicle is crucial for safe driving. In 2018, the National Highway Traffic Safety Administration (NHTSA) significantly altered the landscape of rear visibility with an amendment to Federal Motor Vehicle Safety Standard (FMVSS) No. 111. This amendment, driven by the Cameron Gulbransen Kids Transportation Safety Act, paved the way for backup cameras as a viable alternative to traditional mirrors in light vehicles under 10,000 lbs. gross vehicle weight.
Key Points of the FMVSS 111 Amendment:
- Compliance Options: Manufacturers gained the flexibility to equip new vehicles with either traditional rearview mirrors or a rearview camera system that meets specific performance criteria.
- Field of View: The camera system must provide a view directly behind the vehicle that encompasses a horizontal angle of at least 20 degrees and a vertical angle of at least 10 degrees. This ensures a wider viewing area compared to some traditional mirrors.
- Display Requirements: The camera image must be displayed on a monitor located within the driver's field of view, typically integrated into the dashboard or rearview mirror. Specific display size and brightness requirements ensure clarity and ease of viewing.
- Activation Trigger: The camera system must automatically activate whenever the vehicle is shifted into reverse gear, providing immediate visual assistance during backing maneuvers.
Impact of the Amendment:
This amendment had a profound impact on the automotive industry:
- Increased Safety: Studies suggest backup cameras significantly reduce backover crashes, which often involve young children. Improved visibility behind the vehicle leads to swifter hazard detection and reaction times.
- Technological Advancements: The amendment spurred rapid development and integration of high-quality backup camera systems, contributing to wider adoption and affordability.
- Consumer Preferences: Backup cameras have become a highly sought-after feature, with many consumers now considering them essential for safe driving.

Mercedes-Benz Cars and SUVs Recalled Because Rearview Camera Image May Not Display
(The issue stems from a software problem)
Mercedes-Benz is recalling more than 126,000 sedans and SUVs from the 2018 through 2021 model years to address a safety issue with the rearview camera. The National Highway Traffic Safety Administration says that a software error may prevent the image from the rearview camera being properly displayed. This means that the affected vehicles do not comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, which covers “Rear Visibility.”
In documents provided to NHTSA,
Mercedes-Benz says that the problem was first reported in 2018 by owners of commercial vans who experienced this condition. After delays attributed to the COVID-19 pandemic and additional internal and market reviews, Mercedes-Benz determined this condition affected its passenger vehicles.
When the issue occurs, the driver might notice that the central display would either continue to display the existing image or display a black screen with a message indicating the rearview camera is not working properly.
The automaker says that it identified eight cases in the U.S. from December 2018 through August 2021. Mercedes-Benz has not received any reports of crashes or injuries associated with the problem.
According to the National Highway Traffic Safety Administration (NHTSA) regulations, a “rearview camera image that might not be available within 2.0 seconds (as required by FMVSS 111 S5.5.3) as the vehicle begins to back up might impair rear visibility which might increase the risk of a crash.”

Given the huge fines and penalties imposed it’s understandable that Mercedes took drastic action to correct and check that the reversing camera works correctly on every startup.
They do seem to have taken a sledge hammer to crack a nut though and why calibrate on forward travel?
Seems it’s an issue on all models across the world although E class owners report the noise is annoying but quieter so they probably have more insulation than the GLA.
Probably forced to use the standard camera transport system which was never designed to be deployed continuously.
What is difficult to understand is why Mercedes have refused to acknowledge complaints or even issue an explanation note to customers.
