I purchased a 2021 GLA 200D AMG Line six weeks ago, which had a low mileage and a satisfactory specification.
Residing in France, I own a left-hand drive (LHD) automobile, which was my first. Initially, I found it daunting to adapt to driving while seated on the left side. Consequently, I often misjudged my parking position, consistently ending up two feet to the right of my intended spot.
I am now rather satisfied with the automobile, as I am becoming used to it. However, I must note that the traffic sign recognition system is really poor.
It often provides inaccurate speed readings, such as indicating a speed of 70km/h while the route has a 50km/h restriction in a town.
It has an accuracy rate of around 50%.
The GLA was a replacement for a Ford SMax Vignale that was equipped with speed sign recognition.
The GLA made more faults than the other vehicle, which was a 2017 model.
I had higher expectations for Mercedes in 2021.
I have disabled the option.
Is anybody else experiencing the same issues?

Simply put, the answer is no. A more extensive response will be provided below...

Various specification levels use distinct devices that operate the speed limit sign recognition in varying manners. For instance, the simple specification limit recognition system relies just on cameras, but the more sophisticated version incorporates satellite navigation data in addition to camera detection.

I am not familiar with the specific combination of versions and option packs available for French-spec cars. However, you should be able to determine the features of your particular vehicle by referring to its construction sheet. If the more sophisticated version is installed, a pertinent inquiry to make would be, "is the satellite navigation mapping current?".

Thank you for responding.
Reviewing documentation provided by the primary distributor.
The "Pack Premium Plus" has a feature called "Speed limit assistant by reading signs using a camera".
I understand the concern over the outdated nature of sat nav cartography. However, it is important to note that in some cases, the indicated speed restriction of 80kph would never have been applicable, since we are referring to urban streets inside a sizable town.
I will collect further data and address this matter with my local dealer.

In my experience, the camera-based speed limit assist system only responds to the most recent speed limit sign it detects. I am uncertain about the functioning of this system in France, where the name sign of the town or hamlet signifies the commencement of a 50 kilometres per hour speed restriction.

I am uncertain whether your technology is identical to mine, but my car has no difficulty in accurately interpreting speed signs. However, there are some instances when it mistakenly detects the speed restriction plates on heavy goods vehicles. Typically, it is promptly sorted.
If you have owned the automobile for just 6 weeks, maybe you might consider having them inspect the issue. Is it possible that the windscreen was replaced and something was not correctly reinstalled?

Ensure that the map is regularly updated and that the camera is realigned, especially if the vehicle has received a new windscreen.

Thank you everyone.
I have sent an email to the supplying dealer in order to verify if the first owner of the vehicle had the screen changed. Once I get a response, I will proceed to contact my local main dealer and request their assistance in investigating the matter.

Are the automatic lights and automatic wipers functioning properly?

I inquire because if the camera/sensor module is not functioning correctly, it is quite likely that the screen has been changed but not restored properly.
