  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 the vehicle was stationary and connected to a DC Fast Charging station (Electrify America), a thermal event occurred at the charging interface. The charging connector overheated and thermally fused (welded) to the vehicle's high-voltage charging inlet. The connector could not be released by the vehicle or the station. A technician dispatched by the charging network was unable to remove the connector using standard release protocols. The technician confirmed the equipment had failed and was forced to use physical leverage to pry the fused connector off, resulting in the fracture of the vehicle's charging receptacle. I couldn't charge the vehicle anymore and so I took it to the Mercedes dealership. The certified manufacturer diagnosis confirmed the failure was caused by a "loose connection" and thermal defect in the external charging station cable, not the vehicle. The high-voltage receptacle was destroyed. This failure mode presents a critical safety risk of fire and entrapment, as the vehicle could not be disconnected or moved during the thermal event.

  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 eventually fell asleep and woke up around 4:00 AM extremely cold. The outside temperature was approximately 31°F, and the vehicle had no heating capability due to the system shutdown. Extended confinement in freezing temperatures without heat created a serious risk of hypothermia or medical emergency. This situation caused me to experience a panic attack, and I developed a severe cough afterward, which I believe was related to cold exposure. At approximately 4:00 AM, the vehicle briefly powered on for a few seconds, which allowed me to unlock and open the door and exit the vehicle. After exiting, I attempted to have the vehicle’s battery jumped, but this was unsuccessful. The vehicle remained completely inoperable. I then had to pay approximately $700 out of pocket for towing to a Mercedes-Benz dealership, despite the vehicle still being under warranty. In order to continue my trip to California, I was forced to rent a vehicle at my own expense (approximately $400), in addition to incurri

  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 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.

  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.

  I am submitting this complaint to raise a serious safety concern regarding the Mercedes-Benz EQS 580 SUV. This vehicle is sold and delivered without a spare tire and without run-flat tires. This design choice is dangerous and creates a foreseeable risk of severe harm to motorists. Recently, my wife and I — both senior citizens — suffered a tire failure in a remote area with no cellular service. Because the EQS 580 SUV was equipped with neither a spare nor run-flat tires, we were completely stranded. We were forced to walk miles to find a cell signal to call for help. This was a frightening and potentially life-threatening situation. It is entirely foreseeable that tire failure may occur in remote areas or where cell service is unavailable. A modern vehicle sold in the United States should not leave occupants with no means of mobility or self-rescue in such a situation. This issue poses a heightened danger particularly to: Senior citizens Families with small children Physically disabled individuals Anyone traveling in rural or emergency-prone environments A flat tire in these circumstances can result in individuals being stranded, exposed to the elements, injured, or worse. Someone could easily die in such a situation. In addition, Mercedes-Benz did not disclose at the point of sale that the vehicle lacks both a spare and run-flat tires. Had we been informed, we would not have purchased this vehicle. The manufacturer and dealer have a duty to warn consumers of a safety-critical limitation that eliminates an essential emergency capability. To my knowledge, it is unheard of — for a modern SUV, especially a premium vehicle marketed for safety and long-distance comfort, to be delivered without any means of addressing a tire failure. This is a serious consumer safety issue, and I respectfully urge NHTSA to investigate. A requirement for either a spare tire, run-flats, or clear disclosure at the point of sale is essential to protect the driving public.

  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.

  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 driving of about 25 miles plus. This is brand new luxury vehicle, and I would know if I drove over some thing so big to cause such a major damage. At no point I drove over any thing major - otherwise I would not have thought of 'tire problem' initially. I am really shocked that driving for 40 years, I have never encountered such an issue. My concern is that the car is so smooth driving that it had such a major damage without driving over any large potholes etc. Not sure if other Mercedes EQS has had similar issues. Dealership states that this is not covered under warranty. I just want to make sure that there is no significant manufacturers defect in these parts to cause such a mjaor damage to the struts without any other damage to the underside of the car. I am glad that I did not get into any major accident but dealing with such breakage of car part is beyond my understanding of how such a thing can happen without one realizing that it had happened.

  Description of Incident: While attempting to reverse out of my driveway, I experienced a catastrophic and life-threatening malfunction with my vehicle. I was in reverse gear when the car came to an abrupt, extremely forceful stop, which caused the vehicle to jerk violently forward. This sudden and unprovoked halt put me and my passenger at risk of serious injury. My foot was on the brake the entire time. As the car stopped so unexpectedly, I shifted into Drive in an attempt to inch forward. However, despite my foot remaining firmly on the brake, the car accelerated at full power, without warning, and with no input from me to do so. The car then drove directly into the foundation of my house, causing significant damage. Despite applying constant pressure to the brake, the vehicle failed to stop or respond. This malfunction resulted in the destruction of my home’s foundation and caused bodily injury to both me and my passenger. This was a life-threatening event and could have resulted in severe harm or death to anyone nearby. The car’s acceleration while my foot was still on the brake indicates a severe safety risk and defect in the vehicle’s systems, which also places others at risk.

  The center console display (MBUX) on this 2023 EQS 450 4MATIC fails while the vehicle is in use. There is no warning lamp, chime or message first. Sometimes it flickers on and off; other times it goes fully blank and stays blank, unresponsive to touch. Owner video shows the display working and then completely blank 0.4 seconds later. When the screen is blank the rearview backup camera is unavailable. Selecting reverse produces no image at all. The rear camera image appears only on that center screen, so the failure removes the rear visibility required by FMVSS 111 and leaves the driver reversing with no camera view in parking garages, driveways and residential streets. An authorized Mercedes-Benz dealer has reproduced and confirmed the failure across five visits, from 7,916 miles in August 2025 to 20,789 miles in August 2026, with 28 days out of service. In May 2026 (RO 1410670) the dealer diagnosed fault B159211, a short circuit to ground on the data line between the head unit and the central display, removed the dashboard and replaced a harness. The technician reported that instead of removing the original short-circuited harness he cut off its connector ends, taped the exposed cables and left that harness inside the vehicle. The failure recurred ten weeks later and was recorded on video on 29 July 2026. On the most recent visit (RO 1418392, 26 August to 3 September 2026) the dealer wrote "tech confirmed customer concern," reviewed the video, and recorded fault B162997: the data line between the reversing camera and the head unit has a malfunction. The entire central display was replaced. The defect has survived a software reflash, a harness replacement and a display replacement. This vehicle was previously repurchased by the manufacturer under California lemon law for a defective rearview camera and was certified in writing as fully repaired before resale. The vehicle, the video and all repair orders are available for inspection on request.

On this vehicle, the compressor is a dual-function safety-critical component: it provides cabin air conditioning and, more importantly, active cooling for the high-voltage lithium-ion battery pack. I am filing this complaint because a single-point failure in a component responsible for high-voltage battery cooling should not occur on a vehicle of this age and mileage, and because owners receive inadequate warning of the safety consequences when it does.

I was in shock and initially unsure of what had occurred, as there were no cars around me, and my vehicle continued to operate normally. I looked up to see that the sunroof glass had inexplicably exploded. The sunroof blind was closed, and all windows were shut during the incident. I had been driving for about 20 minutes when this occurred. Remarkably, there was no glass inside the car; around 90% of the sunroof glass simply vanished. Fortunately, the sunroof blind was closed, which likely prevented severe injury to me or potential passengers. There were no cracks, chips, or issues with the sunroof before this incident. I now sometimes experience aftershocks whenever I encounter a pothole or any sudden jolt while driving. Given the severity and randomness of this occurrence, I am gravely concerned about the potential risk this defect poses to other drivers and their passengers. -The sunroof glass is available for inspection upon request. -The sudden explosion of the sunroof put my safety at risk, as the loud noise and unexpected nature of the event caused significant shock.

  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 it to the Mercedes dealer where I purchased the vehicle. There were NO warning lamps, messages or other symptoms of the problem prior to failure.

  Around 5:48 pm Pacific time today, May 8, 2023, traveling westbound on Sunset Blvd (near the Drummond street intersection), the brakes suddenly engaged hard for a few seconds and then released and continued. Speed was around 35 mph and there were no obstructions around. This is the second incident of phantom braking that has occurred in 2 months. Luckily there was no car behind that could have collided into us from the sudden phantom braking.

  Odometer Fraud. The contact leased a 2023 Mercedes-Benz EQS 450 X4. The vehicle was a dealer sale. After returning the lease vehicle to the dealer, he was informed the odometer closure was not available during the drop-off and it would be emailed. The contact stated that the vehicle was returned with the mileage at 17,000. The inspection report also indicated that the odometer reading was 17,000. The contact received a bill that indicated that the mileage was 7,000. The finance office was contacted, and they informed him to return to the dealer. The dealer indicated that the discrepancy was not his problem. The police were contacted, and a report was filed.

  The sunroof shattered and before that the eye brow shattered, as well. No hits to the glass. With the sunroof I wasn’t even on a highway.

  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 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.

  While making a left turn at low speed, I applied the brakes, but the vehicle did not respond as expected and instead appeared to drift, surge, or accelerate forward. The vehicle struck a fire hydrant and a bus stop pole before crashing into a tree. Airbags deployed and both occupants sustained injuries. I suspect a possible malfunction involving braking, propulsion, electrical, or speed control systems. No final cause has been determined. The vehicle should still be available for inspection. Mercedes-Benz USA has opened a case regarding this incident.

  I experienced a phantom braking incident yesterday in my 2023 EQS450+ SUV at 3:11 pm PST. Traveling at around 30 mph, no cars within 20 feet ahead or behind us, the car suddenly engaged the automatic brakes very hard with a loud beep but this condition lasted only a couple of seconds. The impact was hard enough to jolt all passengers in the car. The sound was as if something hit us from behind. Cruise control was not being used at that time. The car then continued to operate normally after that. I have set up a service appointment for this Friday, April 14 at the WI Simonson dealership in Los Angeles, CA. I have reported this to MErcedes Benz using their "contact me" feature on their website. From my research, it sounds like phantom braking is prevalent somewhat widely in the EQS cars but nothing seems to have been done about it so far.

  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.

  Just over two months owning the vehicle (bought [XXX]) I was driving on a smaller highway at roughly 35 mph when the car suddenly came to a stop. There were no obstacles front or behind or the sides. It threw me forward. I was aching and in shock, but needed to get out of the left lane so I pushed the gas pedal and the car moved so I could pull into the left turn lane. I did not know what happened. I did not see any lights on the dash. I was not sure what to do but knew I needed to get off this busy road and the Mercedes dealership was just up the road. I carefully drove to the dealership and explained in detail what happened. The Mercedes dealership told me they got a whole new program for the car sent from Germany and they wiped the previous program and put a new one on my car and that the problem was resolved. On [XXX] as I was driving down the road the same incident happened again. It threw me forward and this time I saw a little red triangle on the dashboard that was only there for a second. There were no obstacles in the road or to my front rear or sides. I sat stunned and shaking and thankful that I wasn’t rear-ended. I again contacted Mercedes and told them that now I am too frightened to ever drive this car again. They told me there was nothing found wrong and to come get i- It is safe enough to drive again. If I had been on the highway at the time, I certainly would have been in a horrific accident, possibly resulting in death. I checked to see if there were previous reports of this to NTSB and there were. I contacted Mercedes USA and they did an investigation and deemed that my car does not qualify for replacement. I didn’t have three strikes to qualify for the lemon law even though it is a life or death situation. They drove the car back to me today. I do not feel safe in that car and never will again. I believe it should be recalled. This is not only an EV issue as my sales rep had a C class ‘23 and it happened to him. Please stop a death. Recall!

  Car turns off completely while driving with "Battery malfunction" and "Towing not permitted" error. This happened while driving on a highway at the end of a bridge going downhill so I was able to pullover to the shoulder before the vehicle came to complete stop but if this happened while on the bridge going uphill, that could've been extremely dangerous as there was no shoulder to pull over to. This has happened about 5 times already and we've taken it to the dealership. They upgraded the vehicle's software at one point saying that would address the issue, but the issue keeps happening. I don't feel safe driving this vehicle knowing that the vehicle can come to a complete stop at any time without any warning.
