The contact leases a 2023 Mercedes-Benz EQS450. While driving at 35 MPH, the vehicle unexpectedly stopped with no other vehicle or object nearby. The vehicle was taken to the dealer on several occasions; however, the cause of the failure could not be determined. The contact was informed that it was a common failure and that other vehicle owners had sustained injuries due to the failure. Additionally, the contact stated that while driving 10-15 MPH and approaching a red traffic light, the failure recurred, almost causing the vehicle to be rear-ended. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 8,000.
Mileage: 8,000
The vehicle throws a “charging fault” error when I try to charge my vehicle with a high speed charger. I tried two different chargers and two different locations with the same result. The safety risk is a faulty high voltage battery system. I have not taken it to the dealer yet. This just happened today. My understanding is that this is a fairly widespread issue and MB is denying all warranty claims and blaming the charging station. The only warning is the “charging fault” message on the dash display.
While traveling cross-country from Chicago, IL to San Diego, CA, my Mercedes-Benz EQS experienced a battery and system malfunction in Erick, Oklahoma at approximately 11:17 PM. At the time of the incident, the vehicle displayed approximately 93 miles of remaining range. I stopped to charge the vehicle; however, the vehicle failed to initiate charging and subsequently lost power. Following the shutdown, the vehicle doors would not unlock. The vehicle appeared to have no usable electrical power, and there were no visible or audible instructions provided regarding emergency exit procedures. I was unaware of any mechanical emergency door release and could not reasonably locate one during the shutdown. As a result, the vehicle effectively trapped its occupants. Both my phone and my passenger’s phone were fully discharged, leaving us unable to contact roadside assistance, emergency services, or any outside help. We remained confined inside the vehicle for several hours overnight. I even
This afternoon, while I was driving on freeway at a normal speed (75 miles/hour) with an ample distance (30 feet) from the car in front of me , I suddenly felt a huge impact. It was so violent that I immediately thought my car was hit by the car behind me. I stopped the car on freeway and called 911. But from the back mirror, I did not see any damage on the car behind me. I got out to inspect my car but did not see any collision damage. According to my online search, this model - Mercedes-Benz EQS - has a frequently reported issue of "Phantom Braking" from the Forward Collision Avoidance System. It was very startling and dangerous experience for me. Now 5 hours later I still feel the pain in my neck and back from the impact. Please address this issue to save lives.
Two weeks ago, I returned back from work and later on in the evening was driving to go to grocery store when the car seemed to get pulled to one side and started shaking when driving around 40MPH. Not knowing what was going on, I turned back and slowly drove it back home. Next morning, I thought may be there is low tire pressure ( even though it was in range), I slowly drove to get air filled. After that coming home the car started pulling on the left side and shaking around 40MPH speed. So I slowly drove it back home with flashers on and then towed it to the dealership not knowing what was going with it. Car has only 6700 miles on it. Dealership looked at it and said that the left rear strut was broken and right rear strut is damaged. No other damage to the car. They think I might have drove over 'some object'. I have the same drive to work for 10 years, I drive about 2 to 3 times a week to work. There is no major trenches or big bumps on the road. Majority of drive is freeway drivin
2023 Mercedes EQS 450 Normal Recuperation driving around 40 mph suddenly the brakes were applied and seat belts engaged with no apparent reason or obstacle. It was for a second and released so no damage except the scare and jolt of the brake. The internet is full of discussions about this Phantom Braking with electric and non-electric vehicles of all brands. This is the first incident in the 3 months that we have owned this sedan and we will be taking it to the Mercedes dealership soon. This car is always giving warning lights and sounds with so many safety features.

Car stopped abruptly on a two lane highway and a flashing warning came up that said electrical failure. Car jerked to a stop. Had to be towed to the dealership. Very dangerous. A friend has the same car and it happened to him twice. The cars do not need to be on the road until absolutely corrected. Needs a recall.
I was stopped at a stop sign and when the light turn green I pressed the accelerator to move forward unfortunately, the vehicle hard braked for no reason. At first, I thought someone hit me from behind since there was no one in front of me but that was not the case. The braking was so violent that it caused my neck to snap back and forth, which caused the back of my head to hit the seat head support. I was going no faster then 10 mph but not slower then 5mph. In turn, the vehicle is available for inspection. My safety was at risk because I had no control or indicator that the braking was going to automatically brake on its own. The problem has not been reproduced or confirmed by the dealer or independent service center because the incident happened today (Sunday) therefore, I plan on making an appointment as soon as possible to see if they can identify any defects. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others since I plan on taking

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.

Please 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
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 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
I drove the EQS without issue for six months. Then, about a month ago while I was in reverse backing out of my garage, the car slammed on brakes and the seat belt forcefully engaged. It felt as if I hit a brick wall. There was nothing behind me--nothing in the driveway. Then last Sunday, October 29, 2023, I was at a stop light and began accelerating down an off ramp. Nothing was in front of me; however, the car slammed on brakes again--with the selt belt forcefully engaging, and I came dangerously close to getting rear ended. My husband turned off the automatic emergency breaking system, and we got an appointment with the Mercedes dealership. They had the car all day on Tuesday and Wednesday (Oct. 31 and Nov. 1), and basically, the dealership is saying they cannot make any repairs because they cannot replicate the issue.
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 issue.
As I was traveling on a highway at 70 mph in my 2023 Mercedes-Benz EQS, 450+, the overhead sunroof glass spontaneously exploded without warning or signs. The glass blew out edge to edge into hundreds of tiny pieces of tempered glass. If it had not been for my *closed* cloth sunroof sunshade, the 100s of tiny pieces of tempered glass would have rained down onto my head and body while I was driving at highway speed. The sound was EXTREMELY loud, like a gun shot or bomb explosion. For a moment, I literally thought someone had shot a gun at my vehicle. I was extremely fortunate that I was able to maintain control of my vehicle, as this sudden explosion could’ve easily caused me to lose control and crash.
