The vehicle pre collision automatically stops the car completely five times with no car or any objects in the front. I took the car to Mercedes dealership to see if they can find the issues, but they can’t. On 04/07/2024 I had my wife record while I’m driving and we got video of the car just completely hard breaking on its own with no cars in the front. I am worry that another vehicle will rear end me at higher speed when it does happen again.
NHTSA complaint 11581634Please note that back in April 2023 my car was lawfully parked, and other SUV (Mercedes MB) was backing up and touch my front bumper. Because of that impact my front plastic grill got cracked and damaged front camera. The estimate to repair was almost $3000.00. I might assume it was a large impact, but yesterday during carwash when my car was not moving, car in front (another small SUV) suddenly rolled back and simple touched my front bumper. Because of that impact i got similar damage - front plastic grill is cracked and front camera is damaged. please note that other car didn't hit plastic grill as bumper is located further front. Its just of impact to front bumper to force front plastic to crack or poorly design of the components. I have both videos of impacts that i can provide upon request. I uploaded estimate from prior accident
NHTSA complaint 11573091On 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 advisor that this was a normal and preventive measure to avoid collisions. To my surprise, he even compared it to his experiences with a non-Mercedes vehicle. Strangely, this wasn't the first time I encountered such an incident; the initial occurrence was in a loaner vehicle provided to me due to other functionality issues with my car. To date, both the Mercedes service centers in Annapolis and Arlington have not taken my concerns seriously, which is deeply troubling. It's alarming that there are others like me facing similar problems, and there seems to be a lack of information on where and how to report these incidents for a resolution. The question remains: must someone be seriously injured or killed before Mercedes takes accountability for these potentially dangerous episodes? My vehicle is presently at the Mercedes-Benz service center in Annapolis, addressing various hazardous functionality issues, including phantom braking, pulsating brakes, and a range of other concerns. Once I receive the service records, I am happy to provide them for review. 1st incident:[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint 11567345Vehicle 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 issue.
NHTSA complaint 11546108On 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.
NHTSA complaint 11525091We 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 time on a local street. We called the dealer and alerted the corporate headquarters but they did not respond. They do not seem to care.
NHTSA complaint 11519767Experienced 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.
NHTSA complaint 11509612On 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 it occurred it happened for no reason at all. I had thought perhaps because my collision avoidance settings were set to the max sensitivity levels that perhaps it's seeing things that aren't there. It was very scary, it was so violent I thought I had hit something in the road, but it was a clear, dry, sunny day with no road hazards, obstacles or anything else that would have caused it. The problem has not been reported to the dealer, but I feel that when it happens again I will take the vehicle in to see if they are aware of what could be causing this problem. Nothing has been reported to the manufacturer, police, insurance or others. There were no warnings prior to the hard braking that I can recall. It just happened unexpectedly and immediately. I get a little nervous now every time I get behind the wheel because I wonder if/when the next occurrence will be.
NHTSA complaint 11507339The 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.
NHTSA complaint 11506074At 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 a cleanly paved and level road at a speed of approximately 35 – 40 MPH. During the drive up the road, the car inexplicably and suddenly stopped, hard, as though I had run into a dense hill of sand. It was a violent and sudden jolting stop, and all four passengers’ seatbelts activated, firmly tightening and restraining us in our seats. My wife’s head whipped back and forth, resulting in an enduring headache for her through the rest of the evening. No one knew what had happened, or why, as there was absolutely no obstruction in the road and no traffic around us. We pulled over and inspected the car and it was in pristine perfect condition with no evidence of any contact of any kind. We looked in the road and it was clear, paved and level. No animals; no objects; no obstruction. When I arrived home I searched online to determine if this had ever before been reported, and it turned up several “hits,” apparently filed with the National Highway Traffic Safety Administration (“NHTSA”) on this very issue, apparently involving both the 2021 and 2022 EQS. My model year is 2023. The discussions I have read point to a possible defect in the Autonomous Emergency Braking System (EBS). It might be the car is sensing something that is not there, and reacting as though it were. At 70 MPH on a freeway, this could be fatal, should the EBS activate suddenly, with no cause to do so, with an ensuing rear-end collision. PLEASE ADDRESS THIS.
NHTSA complaint 11501082To 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 primary latch mechanism fails while driving. The EQS SUV is also NOT equipped with a dashboard indicator light or message warning that the hood is not fully latched when in the closed position.
