The speed limit indicator included in the software package flashes constantly (approximately once per second), both inside the instrument cluster and in the Heads Up Display. The speed limit shown is almost always not accurate to the current speed limit, even when passing multiple very clear road signs showing the speed limit. The car still flashes when the speed limit it is showing is not being exceeded. Furthermore, when it cannot read the speed limit, the indicator will often flash road signs for other countries. All of this is happening within the field of view of the driver due to the Heads Up Display, causing a visual distraction which could result in accident. Mercedes and the dealer are aware of the issue, and according to my local dealer Mercedes promised to fix it last year, and then promised again to fix it by Q1 of 2026, both deadlines having passed. This same information was corroborated by a post on Reddit from a user who spoke with Mercedes. When I spoke to Mercedes support on the phone they indicated that my particular car was not even supposed to have this road sign feature, so the fact that it is appearing on my car is incorrect.

While driving the car at any speed between 35mph-70mph, one of the doors will occasionally unlatch. No more than one has unlatched at the same time. All four doors are set to lock automatically once the car is in motion. When a door unlatches, I get a visual alert on the dash, car dings loudly, and I can visually see a 2-3 inch gap between the open door and the vehicle. The door lock symbol on the driver's door still shows the doors are locked (even when the driver's door is the one unlatched). It is frightening when this occurs. Another issue also occurs intermittently. While driving, the hyperscreen will emitted an alert almost as loud as a tornado siren, the car symbol flashes onto the hyperscreen with red lines along all four sides of the car symbol. Within seconds, the command center turns off. I have no ability to know the speed or manage any controls on the car. I am not certain the car is safe to drive. The problems cannot be be recreated on demand. The manufacturer does not release a list of problems that are corrected by software updates, so I do not know if an update could fix these problems. My local dealer does not know much about the EQ line of cars at all. It is not safe to take photos when this occurs since I am actively driving. The car is available for inspect upon request.
