My 2022 Mercedes-Benz EQS 450+ repeatedly showed "Active Brake Assist Functions Limited," "Active Emergency Stop Assist Inoperative," and Blind Spot Assist warnings, photographed by September 23, 2026. On September 24, I reported these issues and showed photos to an authorized dealer. Electronic repairs were performed, but warnings returned. The repair record lists Blind Spot Assist as "not verified"; I have no record of an Active Brake Assist test. On October 8, while turning left across oncoming traffic, the car was in a collision. Automatic emergency braking did not activate. I know the distinctive sudden braking sensation from previous experience. I cannot determine whether activation was expected in these circumstances. Police attended, and the insurer declared a total loss. The car is at Copart; preservation for inspection has been requested but not confirmed. Please investigate a possible safety-system defect.

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.

About 1000 feet after merging onto a 4 lane freeway with sparse traffic, we were driving the car in the 3rd lane from the right. Suddenly the car's steering wheel took a hard right turn, forcing the car through multiple other lanes and onto the shoulder of the freeway, through an unpaved area, nearly colliding with freeway signs. I was able to regain control of the car before a collision and get back on the freeway. I continued on the freeway at a lower speed and after another 1000 feet or so, the car's steering wheel once again took a hard right turn, forcing the vehicle onto the shoulder, and colliding with a railing and a freeway sign. During this second instance, the lighting inside the car when off completely. During both off these episodes, I had my foot off the accelerator and the brake. Automatic Driving and Driver Assist were disabled. The safety of my self and my passenger were put at risk. The car was free of any warning lamps or inspection warnings prior to the accident. The car is currently in a repair shop.

The contact owned a 2022 Mercedes Benz EQS 450. The contact stated that while driving approximately 15 MPH and approaching a parked vehicle on the side of the road, the contact depressed the brake pedal; however, the vehicle failed to stop. There was no warning light illuminated. Due to the brake failure, the front passenger’s side bumper crashed into the rear driver’s side bumper of the parked vehicle. The contact stated that the vehicle continued to maintain the same speed while depressing the brake pedal. The contact stated that after passing the first vehicle, his vehicle independently took a right turn and continued driving onto the sidewalk and onto the driveway of a home before crashing into the vehicle parked in the driveway which pushed the other vehicle into the garage door. The parked vehicle that was pushed into the garage door then struck the vehicle that was parked inside the garage. The contact stated that the brake pedal was being depressed throughout the failure; however, the vehicle only came to a stop after crashing into the parked vehicle in the driveway. The contact stated that the air bags had not deployed during the crash. The contact was taken to the hospital by ambulance and was treated for back pain, neck pain, and shoulders. A Police report was filed. The vehicle was initially towed by the Police Department and then to an undisclosed location before the contact and the Insurance Company had the vehicle towed to Millenium Auto Body which was an authorized Mercedes-Benz repair facility. The vehicle was deemed a total loss. The dealer and the manufacturer were notified of the failure and a case was filed with the manufacturer.

My car has experienced spontaneous power loss and shutdown on four separate occasions since December 21, 2024. The first occasion was on [XXX] on [XXX] (a major road with a 45mph speed limit) where the car made a loud pop sound and juddered to a stop). It would not restart immediately leaving my family and I stuck in the center lane of a relatively high speed and busy road). The second occasion was on that same drive when it exhibited the same ‘pop’ sound and total power loss—this time on a busy 50 mph curving road. I managed to nurse it to a side street where it would not immediately restart and had to be flat bed towed to the dealership (Mercedes of Plano) The car was in the shop for approximately a week and a half while it was repaired by updating the software. On [XXX] the car again lost power spontaneously on our street and was again towed via flat bed to the dealership. It has been at the dealership since then and they have reloaded the software and test drove it multiple times. I was slated to pick the car up again when I got a message from Mercedes of Plano that the car had failed on them and would not restart. They have escalated this issue with Mercedes and opened a TIPS case for specialized support from Mercedes.

My wife has experienced six emergency braking events where there was no other car around. Three of the events have occurred at the exact same place. First event: backing slowly out of a parking space and the car suddenly stopped with no traffic in the area Second event: Backing out of a parking space (no other cars in the parking lot) and the car suddenly stopped Third event: Going forward in the Interstate at about 60MPH when the car suddenly stopped Fourth through Sixth events: Going forward on a city street between 30-40MPH when the car suddenly stops at the same exact place (different times of day). Three different dealers have been dealt with. Each one says that they cannot recreate the issue but that it should be cleared up with the next software update. Yet, it continues to happen. Manufacturer has been notified but has not asked/offered to inspect the vehicle or the area where the issue can be recreated (however, we have recently notified the manufacturer - we relied on the dealerships in the past year). Police nor insurance representative have inspected (nor been asked to in all fairness). Each time, either immediately before or contemporaneous with the braking has been a loud audible beep. Safety of the general driving public is at risk, not just the driver and occupants of the vehicle, because a sudden emergency braking incident with no hazard present is dangerous and can create the exact issue that the system should be preventing: a collision. The date of the incident listed is the approximate date of the last incident. The first one was in the Spring of 2023. The vehicle was purchased used in January of 2023 with approx. 4k miles on it. It now has 16,640 miles on it.

The “Active Assist” features of the vehicle [Blind Spot Assist, Braking Assist, Distance Assist, Emergency Stop Assist and Lane Change Assist - was not able to check all of these above because of the selection limit] have repeatedly and randomly become inoperative while I was driving the car. I have expressed my safety concerns with the service department and management of the dealership that sold me the car. While they have returned the car to me with the malfunction temporarily cured, it has recurred on more than three occasions, sometimes “fixing” itself and other times requiring dealer intervention. The dealership cannot assure me that it is fully and finally “fixed” and I have no reason to believe that the issue will not recur as it has so many times in the past. The dealer also refused my request to say it cannot be fully and finally fixed, but their offer of $50,000 for this car (less than half of the total purchase price for a car with only approximately 14,500 miles) on a trade for a used 2022 model priced at $110,000 is some indication that they view my vehicle as flawed. I do not feel safe in the car and their offer requiring me to take a substantial haircut on this purchase is not acceptable, particularly since they cannot (or will not) confirm one way or the other whether the issues are fully and finally fixed.

There is not a specific incident.The brakes are and have always been difficult to brake since I purchased the Mercedes EQS+ in 2022. I was told that all mercedes Benz electric cars were difficult to brake. It is generally recognized by the service representatives, the electric car technicians. Mercedes salesmen have had discussion about this issue in their weekly sales meetings. I have had a lot of safety recalls installed and had taken my car to a person who sells and repairs upper end cars including Mercedes Benz and BMW to see what he thought about how my car was driving. I was surprised when he focussed on the brakes. He said they were very dangerous and told me not to drive the car. I told him that in the beginning Mercedes service said the car was very heavy and I would get used to the brakes. My person said "he has a 20,000 lb motor home. When he applies the brakes they stop the motor home. "People drive trucks heavier than your car and when they apply the brakes the truck stops". So, I spoke again to the dealership. I asked the technician if he could call corporate and tell them of the general concern of the mercedes dealership employees about the brakes. He said NO. The only person who could make that happen was me and other drivers filing a complaint to NHTSA. He said if there were enough complaints Mercedes would design software an open a new safety recall that would enhance the effectiveness of the braking system. So, that's what I am doing. I tried to file a complaint before by phone and the lady totally misunderstood my complaint and her research not at all applicable. If it is true that all the electric mercedes benz cars have brakes like mine I hope Mercedes will address the issue before someone is hurt.The car is especially inefficient in speeds of 45mph and over. In slower speeds they are more manageable if not in stop and go traffic. I wonder how many accidents have actually been because of these brakes? Allow more room between cars.

re-open it again with the Key Fob. Sometimes it takes a while for the car to unlock. I've been having issues charging the vehicle since Day 1 of purchased since the computer in the vehicle is not able to communicate from time to time with the Electrify America charging stations for plug and charge. I will need to call in to Electrify America charging stations so they can do an override to be able to charge the vehicle. I have to waste 2.5 hours every time I want to charge the vehicle which is usually 2-3 times a week. Another safety concern I have is that when driving around 45-50 mph and I am attempting to apply the brake softly to start slowing down due to heavy traffic, I have reported to the dealership that the brakes feel like it takes some time to brake and slips. I have to pump the brake 2 to 3 times so the brakes can start working right. The dealership stated that is possible that the ASB braking system might be working correctly but that they could not replicate the symptoms that I was describing. I have talked to Mercedes Benz USA and open up a claim and asked them to do a buyback of the the vehicle due to all of the safety issues concerns I have expressed. The Case Number I have open with right now is (Case #XXX) The case is being handled by Marry - Executive Referral Manager of Mercedes-Benz USA Customer Assistance Center. She can be reached at 800-367-6372. I also reported these concerns to NTHS of the state of California and I have an open case # XXX. I reported all of this issues to them on Thursday 12/7/2023 around 8:30am Pacific Time. NTHS confirmed that not only mercedes is experiencing this issues but other customers has reported this automatic phantom braking happening with other vehicles as well and is very unfortunate and extremely dangerous. I am concern with having to drive my vehicle in this conditions since an accident already occurred do to vehicle braking on its own and going reversed on its own while on drive.

Car is equipped with Distronic cruise and has maximum 4 car lengths stopping distance. It was set on 4 car length. While driving north on 55 fwy and exiting to 405 fwy in California. Exit (single lane) was dead stop due to traffic and while I was on cruising at 70 mph. Car would not stop and I had to take over to stop- hard braking just in time. The SUV behind me had to swear to emergency lane ( right side) to avoid a rear end collision. All my family (4) were screaming that it could’ve been a serious accident. This has happened more than once. Even on the surface road reaction to stop is late and jerky. My self and my wife hates it. 3 attempts at the dealership has not resolved it. [XXX] of Ontario Ca answer is, it up to the specs. My request for repurchase was rejected as it doesn’t fall into Lemon law.

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.

I was driving my EQS on Thursday May 25th, 2023, at about 1:30 PM heading eastbound on the southern portion of the 202 Loop in Maricopa County AZ at a rate of about 75 MPH on a clear day with minimal traffic when without warning my vehicle locked up the brakes in an emergency stop. The tires left skid marks, seat belts tightened, and the screen in form to me flashed red warning signs. It happened so fast and without warning that when I realized we had come to a stop I look in the rear-view mirror and saw a truck headed towards my car, so I accelerated, and the car moved forward. Once off the freeway I drove the remaining 2 miles home along city streets at a low rate of speed and contacted Mercedes and Mercedes Benz of Gilbert. I was told that there was a defect int eh software pertaining to the EBS and that a software update would resolve it. I have the car back now but do not feel safe in it.

The 2022 Mercedes EQS 450 has been an ongoing dangerous driving experience for me. I have been jolted and frightened over and over as the car's autonomous emergency system fully engages when driving as well as when it does not engage when I’m stopped at a light. I have expressed my safety concerns on numerous occasions to the management at the dealership. As I am writing this I see on your website, there is an unrepaired recall on this car with a remedy not yet available. In April, 2023, the car stalled and the messages below appeared on the dashboard: Attention Assist System Suspended Malfunction. Drive at max. 50 mph Stop Vehicle Level Too Low When the car was at the dealership, I was told, while it is a new model, they are trying to figure out the problem. I no longer want to be a guinea pig and endanger my life driving this car. In October, I backed into a low brick wall when the sensors did not alert me. At that time, I told the service department about the sudden braking and stalling. I had the damage repaired, costing $7000 and was told all was fine with the electrical panel. The dealership is now telling me after the car was there for 2 weeks, the car is fine. After being told this in October and with ongoing issues, I have no reason to expect it to be any different this time? I feel unsafe driving this car and do not want to jeopardize my life. Originally I was told Mercedes is aware of these issues and they would offer me a buy back and walk away. Now they are saying the car is fixed but Mercedes will offer me $5000 towards a trade-in and $70,000 for my car with less than 3000 miles. Offering me a substantially less amount of money than I paid for the car with on going safety issues is not acceptable.

- 11008080Issue Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2024 S-Class and EQS (223 and 297 platform) vehicles, the DRIVE PILOT Supplemental Booklet does not correspond to current production specifications. What Were Doing MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will replace the DRIVE PILOT supplemental booklet.
- 11008062Complaint The electric range does not meet customer's expectations. Cause The following information is being provided for educational purposes only: At Mercedes-Benz, we believe that our vehicles should display to the driver a range that in all probability can actually be achieved. These ranges are predictions - the range actually achieved may therefore differ from the range shown. The calculation for the predicted range takes into account the current outside temperature, the set temperature of the air conditioning system, the battery capacity and the characteristics of previous journeys (sporty/anticipatory driving style). Where previous journeys are concerned, factors given particular consideration are individual driving style and the use of other power consumers (seat heating, lights, charging function for smartphones, etc.). It is therefore possible that data from the last few hundred kilometers driven is also used in the calculation. Consequently any change in usage behavior will only slowly affect the predicted range. If active navigation or active commuter route is used, additional information about the route ahead (for example elevation profile, traffic volume) can be included in the range calculation. Remedy The customer's individual input to the range can be reset. Depending on the vehicle, the reset can be done in the instrument cluster or the head unit. For plug-in hybrid vehicles of model series 166 (all), 205 (up to modification year 18/1), 213 (up to modification year 17/2), 222 (up to modification year 17/2), 253 (up to modification year 19/1), the range can be reset by resetting the trip computer ("From reset", "From start" and "Day cycle counter"). After the reset, a value based on the certified range will be shown. For electric and plug-in hybrid vehicles of model series 205 (from modification year 18/2), 213 (from modification year 18/1), 222 (from modification year 18/1), 253 (from modification year 19/2) and model series 118, 167, 177, 206, 223, 247, 293, 295, 297 a reset is only possible by resetting the head unit to the factory settings. This will delete all saved customer data and any settings made (e.g. radio settings, navigation destinations). If necessary, therefore, back up the customer data onto a USB flash drive using the Backup function before performing a reset. As from vehicles with NTG 7, Mercedes me is used for the making the backup. After the reset, an empirical value is displayed that is based on normal use of the vehicle and the current climatic conditions (set temperature and outside temperature - commensurately higher values will be achieved if the air conditioning system is switched off). Depending on driving style, outside temperature and which power consumers are actually switched on, the achieved range may significantly exceed this range, but likewise may also fall significantly short of it. Further information on battery capacity and aging can be found in document SI47.70-P-0070A.
- 11007974Complaint Headlamps leaking or fogged Cause The fogging of the headlamp is a natural phenomenon which can occur under certain climatic conditions. In contrast to a leaky headlamp, physical fogging does not result in a technical impairment of the headlamp. A leak test must be performed to determine if physical fogging exists or if the headlamp is leaky. Remedy In advance, observe LI82.10-P-078301 "Headlamps or Front Fog Lamps Leaking or Fogged". 1. Prepare headlamp/check for external damage: For headlamps with a closed system 1. Check the headlamps for any external damage and check also for correct seating of the Gore-diaphragm/correct latching of the cover caps. 2. If the headlamp exhibits any external damage, replace the headlamp. For headlamps with an open system 1. Check the headlamps for any external damage and seal off the vent then make sure the cover caps are latched correctly into place. 2. If the headlamp exhibits any external damage, replace the headlamp. Note: A headlamp with external damage is not a warranty or goodwill case. 2. Leak test of headlamp with overpressure: Connect test adapter to pressure tester. (Figure 1) Check test adapter for leak tightness. To do so, connect plug and coupling (picture 2) and apply a maximum overpressure of 30 mbar. The pressure must remain constant. If the pressure does not remain constant, use a new adapter. Seal all the outlet openings using sealing compound and the given diaphragm with the plunger (picture 3). (Picture 4) Make allowance for the different headlamp variants here (there are different outlet openings). Check if the headlamp needs to be removed to gain access to the diagnostic socket on the headlamp housing. Plug the adapter onto the diagnostic socket on the headlamp housing. (Picture 5). Apply a maximum of 30 mbar overpressure to the headlamp housing. Note: If the maximum overpressure of 50 mbar is exceeded the headlamp seal will be damaged. If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is not leaky and the problem is down to natural physical fogging. If a pressure drop of more than 10 mbar is measured within 30 seconds, the headlamp is leaky. Note: The leaky position can be localized with the aid of soap suds. Replace any leaky headlamps. Note: Desiccant packs can be installed for headlamps that are not leaky. See: LI82.10-P-064766 Fogged headlamp, desiccant pack installed - open ventilation system LI82.10-P-078304 Fogged headlamp, desiccant pack installed - closed ventilation system
- 11007966Complaint Display dark (total or partial) of one or more ASCM (AMG) steering wheel button displays - see attachment. Note: There is no loss of vehicle functionality due to this complaint. Cause Software can cause a partial display on the ASCM. Remedy Please perform the following steps in the event of a total or partial display of the ASCM displays: 1. Perform a hard reset (disconnect power supply) of control unit A74/2 (ASCM) for 2 minutes. 2. Perform a software update of the A74/2 (ASCM), N145 (DRVU) and A26/17 (HU). 3. Reset the user profile via the head unit settings menu. (Full factory reset)
- 11007796Complaint Individual functions such as sliding sunroof or roller sunblind can no longer be operated using the gesture recognition system. Cause Gesture recognition system control unit software N168 Remedy For vehicles before modification year 23/2: A remedy is currently being developed. Replacing parts will have no effect. For vehicles as of modification year 23/2: Considered to be a series production configuration. A change will not be possible in future.
- 11007753Complaint Headlamp or front fog lamp leaky or fogged Cause Fogging of the headlamps is a natural phenomenon, which can occur under certain climatic conditions. It does not lead to any technical impairment of the headlamp. Headlamps comply with all applicable standards. If a pressure compensation diaphragm is fitted in the housing cover, then the lamp unit is a "closed system". Remedy Headlamp: Remedy 1 Clearing fogged/condensed LED headlamps and LED rear lamps: 1. Drive vehicle into workshop (temperature higher than +18 C/+64.4 F) and connect the exhaust extraction. Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood or trunk. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing fogged/condensed halogen/xenon headlamps: 1. Drive the vehicle into the workshop (temperature higher than +18 C/+64.4F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine. 3. Open the hood. 4. Switch off the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Note: If there is no visible reduction in the formation of condensation, check the headlamp for a defect. (See Remedy 2) It is not physically possible to defog the headlamps completely. Fogging does not impair the operation or the service life of the headlamp. Remedy 2 A Damaged headlamp can be identified as follows: 1. Check the headlamp for external damage and that the cover caps and the diaphragm are correctly seated. 2. Check the electrical connectors of the plugs and pins. 3. Check for leak tightness in accordance with LI82.10-P-078307. The test can only be conducted on headlamps. 4. If the headlamp or the rear lamp has any external damage, replace the component part in accordance with the WIS instructions. Note: External damage to the headlamp/rear lamp or faulty seating of the cover caps does not present a warranty or goodwill case.

- 11007673Complaint Damage or discoloration to paint protection films on vehicle. Cause Chip protection films are a wear item that may need to be replaced over the life of the vehicle. They are typically not covered by vehicle warranty. Remedy To properly install a paint/chip protection film, please follow the below guidelines: #1 - Utilize a solution that is 0.2% soap solution (1,000ml of water + 2ml of liquid soap). #2 - Clean the paint surface and ensure it is dust-free. #2a - When cleaning, you can utilize isopropyl alcohol (Rubbing Alcohol) to assist with cleaning. #2b - We recommend a lint-free rag for secondary dusting. #3 - Wet hands with the soapy water solution to protect the adhesive surface. #4 - Remove the backing paper from the film completely. #5 - Moisten the vehicle surface with the soapy water. You can also lay the protective film with adhesive side out onto the wetted surface to also cover the adhesive layer in the soapy water solution. #6 - Remove film and flip over to gently place adhesive side against the paint surface. #7 - Working from the center out, use a squeegee to press the soapy water solution out from under the film. Use sufficient pressure to firmly press the film into the paint surface, but not an excessive amount to damage or stretch the film. #8 - Allow film and paint to "cure" until all of the moisture has evaporated. At this time the adhesive should be dried and cured enough for sufficient hold to release the vehicle.
