At approximately 10:30 p.m. on January 8, 2023 I, and three passengers (my wife, and another couple), were completing a one hour drive returning from an event in southern California. We traveled on the freeways as we headed home. The speeds on those freeways average between 65 and 75 miles per hour with the flow of traffic. I exited the freeway and pulled up to a traffic light. I made a right turn at the light, then traveled up the road. The weather was clear and dry, and there were no cars either behind, in front of, or beside me as I drove up…
The contact owns a 2023 Mercedes Benz EQS580. The contact stated while his wife was driving 40 MPH, the vehicle experienced phantom braking without another vehicle nearby. The contact stated no warning light was illuminated. The driver was able to continue driving to her destination. The vehicle was not diagnosed or repaired. A dealer was not contacted. The manufacturer had not been informed of the failure. The failure mileage was approximately 4,000.
Vehicle would start and then shutdown. It would display the battery malfunction error. You would need to reset the vehicle with the key in order to activate/start the vehicle again. Dealer said they need to replace the MUC but Mercedes told the dealer to try a software update before. The vehicle is still not running the more recent software RL_NTG7_E316.505_22092AC3. Other vehicles are running E330. I don’t believe the dealer updated my software and this issue could happen and caused the vehicle to become disabled somewhere which would case an …

Experienced phantom braking on car. Date: 2/28/23. No car's in front. Sunny day. I have video dash cam proof but it is 70 mb. I can give it to you guys if needed for proof.
To be clear, there has been no incident with my vehicle due to the lack of a hood latch safety release. This report is being made to call attention to a possible safety issue. The Mercedes-Benz EQS SUV is fitted with two typical hood release latches, one on each side, operated by a single hood release lever in the cabin attached to the latches with a cable. The hood is NOT equipped with a hood latch safety release normally found on automotive hoods. The lack of a safety release increases the possibility that the hood will fly open if the prim…
We were driving locally, and the car stopped abruptly for no reason. There was no one and nothing in front of it, no animal around, and no reason for the stop. Had there been someone behind us, we would have had a big problem. We called the salesperson at the dealership only to learn that he had moved to Germany. We were told that another representative would return my call in about six minutes. No one called. A week later, we were on the highway and, also for no reason, the car slowed abruptly, and then resumed its speed. It happened a third …

On two occasions I was driving on city streets, 35-45 miles per hour without any vehicles nearby and all of a sudden the vehicle applied a hard brake, as if the vehicle had sensed a pending collision or something, but nothing was around. I purchased the vehicle new in October of 2022. The first time this occurred was a couple of weeks after I had bought the vehicle. I had changed the recuperation mode setting, so when it occurred the first time I thought that might have affected it. This occurred on a clear, dry, sunny day. The second time…
On June 1 2023 at 6:24 pm, driving at around 40 mph, the car suddenly braked hard and lurched to the left. There were no cars or other obstructions in front of the car. This braking and lurching to the left lasted a few seconds, but almost came to a complete stop. After a few seconds it resumed normal operation.

On two separate occasions, while driving my 2023 Mercedes-Benz EQS 450 SUV, my vehicle abruptly came to a stop on the highway. The sudden and intense phantom braking caused me to experience whiplash on both occasions, even though there was no imminent collision threat. What was particularly concerning is that my car usually alerts me to any potential dangers and prompts me accordingly, but in these instances, it came to a halt unexpectedly. I reported the issue to the Mercedes-Benz of Annapolis Service Center, only to be told by my service advi…
