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.

My 2023 EQS 580 randomly stops while driving. It has happened 5+ times while traveling at speeds between 10-25mph. My dealer here in Atlanta has replaced the front sensor which didn't resolve the issue. I am thankful that so far the vehicle has not stopped on city streets and not highways. There are no warnings just a hard stopped like other complaints state. I comtacted Mercedes support but they have not been helpful. The vehicle is back at the dealer..

Mercedes Benz USA has been equipping their 2023 EQS580 4Matic Sedans with Summer tires. It makes the vehicle very unsafe while driving in Winters. These are the tires which are not supported by the tire manufactures on their websites, but only supported by Mercedes Benz USA on their website. I am trying to report this so that it can be looked into. This could be a reason for creating car crashes. There was no logical reasoning given to me on why this is the case. The tires given to me is not rated to be driven below 45 degrees Fahrenheit. How can a manufacturer expect for anyone to drive a vehicle, safely, with these stock tires.

I now have experienced a third incident (within 30 days) where the audio and communications fail in my 2023 EQS580. This causes the car phone, radio, and other audio mediums to become inoperable. This has happened on three separate times during the month of June, and I placed the vehicle in service at the dealership each successive time; the vehicle was released on June 4th, June 10th, and July 3rd). Please see attached picture. Additionally, as I have conveyed to Mercedes-Benz (via the app and via email), as well as the service team at the Mercedes-Benz dealership/service center here in Honolulu, after the service department worked on the vehicle in early June, the app no longer functions as it did before being serviced. Specifically, I can no longer add charging pauses via the app. Whenever I attempt to add a charging pause during the app, the Mercedes Me app crashes and closes. I have deleted the app and reinstalled several times; to no avail. In addition to the dealership not being able to correct the problem, I have contacted Mercedes-Benz several times, to no avail. The "Customer Care Center" representatives merely send my call to the voicemail of the Customer Care Expert (James), and he has yet to return ANY of my calls. Ownership of this expensive car is now an exhausting headache, as it does not operate in the manner in which it was advertised

Two weeks ago, we got warning messages about the Active Steering function being inoperative and the Active Emergency Stop function being unavailable. Additionally, the driver side rear tire has consistenly lost air pressure repeatedly since the car was purchased in the fall of 2023. The dealer examined the car and was unable to replicate any of the issues and returned the car to us without any repairs or modifications being done. Yesterday, we were driving on [XXX] going from Winter Park to Granby around 60 MPH. Suddenly, we heard something that sounded like a bomb - a large BOOM followed by the sound of shattering glass. We looked up and it appeared the sunroof had shattered. If the interior screen was not closed, we would have been rained on by glass. We got off at the next exit and saw that the glass on the roof was shattered and large pieces were missing. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Severe safety issue involving my 2023 Mercedes. On [XXX] around 2pm, I experienced a terrifying incident while driving northbound on [XXX]. At approximately 59 mph, with clear weather and no vehicles nearby, a loud blast suddenly erupted from my vehicle, a sound similar to a shotgun blast or fireworks. 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. If the sunroof blind had been open, glass shards could have injured me or any passengers. - The vehicle has been inspected by the manufacturer; they are not willing to correct the issue. -There were no warning lamps, messages, or other symptoms of the problem prior to the failure. The incident occurred without any prior indication or warning. I urge the NHTSA to investigate this matter promptly to ensure the safety of all motorists. Such an explosive failure of a vehicle component while driving is not only alarming but could have catastrophic INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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!

Complaint During part of the steering movement, it feels heavier or more difficult to steer in the same spot every time. OR Rattling, humming, dry sliding/gravel noise from the electric steering system when steering (see attachment). Complaint does not impact the ability to safely steer or control the vehicle. Cause Ball screw drive (KGT) of electric steering damaged by: 1. External force due to: ‑ Hitting the curb/posts with the front wheels. ‑ Driving over obstacles (e.g. pothole/ threshold/ speed bump/ gully) at an inappropriate speed. 2. Corrosion/ water ingress through a damaged boot (see attachment). ‑ Cracks (1) ‑ High pressure cleaner (2) ‑ Animal bite (3) See various examples listed in the attachments for examples of outside influence. Remedy Remove boot clamps closest to steering gear housing on both left and right (as seen in "Steering Rack Boot Clamp Location"). Pull back boot and inspect for rust, broken end stops, water, or any other anomalies. Replace electric steering. Note: Steering gears replaced due to outside influence or damage must not be claimed under warranty!

Complaint Tailgate opens unintentionally. Cause Accidental or unnoticed activation of the button to open the tailgate on the vehicle key. EXAMPLE: when stored in trouser pocket, handbag etc. Remedy As of the 6th generation, the vehicle key can be recoded so that the tailgate no longer opens as a result of a long press on the button, but by double‑clicking on the button instead. This reduces the likelihood of the button being activated accidentally or unintentionally. The recoding can be carried out as follows: 1. Add SA Code O19 into VeDoc (O for Oscar, not "zero") • an XSS ticket may be necessary to add the SA code 2. Perform SCN coding of EIS N73 control unit 3. Deactivate the vehicle key (a successful deactivation is indicated by the LED lighting up 2x briefly and then 1x for a long period). 4. Place the vehicle key in the storage compartment on the key symbol and turn on the ignition. IMPORTANT: all other vehicle keys must be outside the recognition range of the vehicle when doing this! Perform steps 3 and 4 successively for all vehicle keys. Notes: 6th, 7th and 8th generation keys can be deactivated as follows: Up to modification year 22/1 by double clicking the "Lock button" As of modification year 22/1, by press and holding the “Lock button", then double‑click the “Unlock button" at the same time. On model series 167, the storage compartment with the key symbol is located in the armrest. The SCN coding from the EZS is only transferred correctly to the vehicle key under the following conditions: Only one vehicle key is located in the vehicle, this key has been deactivated and it is positioned on the marking in the storage compartment for the data transfer. The costs for this adaptation are to be borne by the customer. For the newer BR 174, 178, 244, 248, 520, and 540, a software update must be initiated, as there is no way to perform SCN coding.

Complaint Traffic sign symbol for "Traffic Sign Assist" is blinking in instrument cluster without obvious cause usually with one of the following scenarios: • Flashing without a speed limit ("‑ ‑"). • Flashing when current vehicle speed is under speed limit. • Flashing between US speed limit symbol and European speed limit symbol. NOTE: • Verify that the concern falls under one of the attachment videos. If not, then it is outside of the scope of this LI. • This also does not cover "Traffic Sign Inoperative" messages on the instrument cluster. Cause There are two identified reasons for this concern: 1. Country code information stored incorrectly at a particular geographic latitude range. 2. Incorrect reference data when the vehicle is started and a GPS signal is not immediately available. Remedy Update head unit software to latest version and the re‑check function in the same location. If vehicle is still exhibiting one of the symptoms as described exactly as in the complaint section or as shown in the video attachments, open a TIPS case to the Body/Chassis/Entertainment inbox with the following: • Video of the concern. • Exact location (latitude and longitude is best)

Complaint The following most common complaints may be observed: • Brief connectivity interruptions when using Apple CarPlay over Wi-Fi • Audio cuts out • Device not recognized • No operation possible Cause There are multiple possible causes for an iPhone disconnecting from a vehicle’s head unit while using Apple CarPlay. These include hardware, software, and environmental factors: Environmental Interference External Sources: • Passing under toll bridges, driving near airports, or areas with heavy electronic interference (e.g., as described in LI82.85-P-076157) can cause connection drops. Cellular Networks: • Interference from nearby cell towers operating on similar frequencies (usually 2.4GHz or 5GHz) can disrupt the signal. Storage Location: • Keeping your phone in a handbag or surrounded by other objects inside the vehicle can create physical or electronic interference. Device and Software Issues Head Unit Software/Hardware: • Outdated firmware, bugs, or hardware faults in the vehicle’s head unit can prevent a stable connection. iPhone Software/Hardware: • Similar issues in the iPhone, including buggy iOS updates or hardware problems, may affect performance. Reset or Reboot:• Automatic rebooting or resetting of either the head unit or the iPhone will temporarily disrupt CarPlay. Connection and Settings Wired Connections: • Faulty Cable: A damaged or poor-quality USB cable can cause intermittent or total loss of connection. • USB Port Issues: Dust, debris, or physical damage in the USB port of either the head unit or the iPhone can also lead to disconnects. Wireless Connections: • Intermittent Bluetooth/Wi-Fi: Unstable wireless communication (Bluetooth/Wi-Fi) can frequently break the Car- Play connection. Power Management: • Battery Saver Mode: Enabling low power mode may restrict background processes, affecting CarPlay. • Vehicle’s Electrical System: Unstable power delivery from the car’s battery or electrical interruptions can cause the head unit to malfunction. Phone & App Configuration Phone Settings: • Incorrect or conflicting settings (especially Bluetooth or Wi-Fi) on your iPhone can interfere with the CarPlay link. • Third-Party Apps/Profiles: • Installed apps or configuration profiles may conflict with CarPlay’s operation. • Native apps are apple maps, apple music, audio books, apple news, podcasts, messages and phone. All other apps are considered third party apps. App Conflicts: • Running conflicting apps that require similar system resources as CarPlay can cause instability. Mobile Data Plan: • Streaming from online sources without sufficient mobile data can result in lost connectivity. Other Factors Heat & Overheating: • If either the phone or the head unit overheats, they may disable certain functions to prevent damage, leading to disconnection. User Actions: • Accidentally disconnecting the device in settings, or physically moving or bumping the phone or cable, may disrupt the connection. Remedy FUP6 (E605.8) software has been released for the following chassis: 118, 177, 243,247,206,254,167,294,295,296,223, 297. Flash available software for the head unit and test for function. The LI will be updated once available for the remaining chassis. If the complaint remains after the SW update please continue with the steps below. Guided Diagnostic Path for Apple CarPlay Connection Issues: Please follow the steps below to systematically diagnose and resolve CarPlay concerns:Update Devices: • Ensure the iPhone is updated to the latest available iOS version. • Ensure the vehicle’s head unit is updated to the latest software version available. Isolate the Issue: • Check whether the symptom persists with another iPhone running the latest iOS version. • Test both wireless and wired CarPlay connections: • Does the issue only occur with wireless CarPlay? • Does the wired connection to the phone function correctly? Further Troubleshooting Steps: • Reboot the iPhone. See attachment for further instructions.

Complaint Customer Complaint: - AC charging is not possible. - The departure time, charging pause, location-based charging or target SOC limit is automatically set to 50% or to a random value in the Mercedes me application or in the charging settings on the head unit display. (Picture 1 & 3) - Incorrect notifications appear in the Mercedes me application for charging-related functions. (Picture 2) Related DTCs in quick test: No related fault codes (DTCs) are stored in the relevant control units. CPC3 - N127 (Drivetrain control unit) OBL223_GEN4 - N83/11 (Alternating current charger for high-voltage battery) DCB223 - N116/5 - Direct current charge connection unit (DCCU) Picture1 The target SOC limit is automatically set to 50% or any random values during charging. Picture 2 Incorrect notification Example “Unable to unlock charging cable. Picture 3 Incorrect settings of charge interruption or pause. (If applicable) Cause - The Customer shares their Mercedes me credentials (password) with a third-party application, for example, a wall box application. This causes the Mercedes Benz backend server to receive random requests to reset the maximum SOC, departure time, charging pause, etc. - Charging settings are set incorrectly, for example, incorrect departure time, charging program, charging interruption/ pause, etc. Remedy The remedies below may vary depending on the customer complaint. Refer to the remedy that best matches the customer complaint. Remedy 1: The target SOC limit is automatically set to 50% or to random values during charging. - Change the Mercedes me login password on the Mercedes me homepage. (My Account > Login and Security > Reset). (Refer to Annex 1). Previously granted authorizations should then be revoked so that the charging settings can no longer be changed by external applications. Advise customers not to share the new password again. - Are there any sub-users? If yes, revoke their rights and reassess the function. -If differences between the vehicle and the Mercedes me app are visible, a new synchronization is recommended. Turn off Digital Extras through the Mercedes me app or the MMCR portal, and then turn the services on again. Remedy 2: Incorrect notifications in the Mercedes me app for charging-related functions. - Restart synchronization between the app and backend. Turn off Digital Extras through the Mercedes me app or the MMCR portal, and then turn the services on again. (Refer to Annex 2) Remedy 3: Incorrect charge interruption or pause setting. - Perform a factory reset of the head unit (A26/17). (Home > Functions > System > Reset), or turn off/correct all charging settings. (Refer to Annex 3) Additional Information: (Good to know) The LED on the charging inlet or socket indicates whether charging is completed or paused. 1) If the target SOC is reached, the charging inlet LED lights up Blue/Green without flashing. 2) If charging is paused, the charging inlet LED lights up orange without flashing. Additionally, the head unit charging settings display a charging pause. Note: Do not replace any hardware components for these complaints. If the complaint cannot be solved, please contact via TIPS or CAC.
