Incident

Jul 15, 2026

Initial vehicle failure started January 22. 2026 with an initial recall software attempt to correct the battery safety. My car then became undriveable. The Safety Fire Risk recall started February 9, 2026, there is still no remedy and direction from the manufacturer due to the fire risk are to PARK OUTSIDE and not charge above 80%. I am coming up on 9 months and no parts are available to correct this manufacture defect. THIS IS NOT A TIMELY REMEDY. I am unable to use the vehicle as intended and designed as most places I frequent including work have parking garages. Mercedes Benz has placed the liability on me for their inferior product that they are unable to fix to date. The car is deteriorating from the required outdoor parking only. I have a horrible odor from the HVAC system that has been disinfected 3 times already and still smells. All 4 tires have prematurely dry rotted to the point the dealer recommends replacement. Paint and molding fade. Most recently rodents got up in the undercarriage and chewed wires which control the right side door locks. To date all of these items remail unrepaired and only the HVAC odor was attempted under warranty, the others I was told are not covered. I always park my vehicle in the garage to avoid all of these items and many more which I expect to eventually happen as well.

I own a 2023 Mercedes-Benz EQB 300 4MATIC. My vehicle has multiple unresolved high-voltage battery safety recalls. Recall 25V050/MBUSA campaign 2025040005 concerns a potential internal battery-cell short circuit and fire risk. I had the BMS software update performed, but Mercedes later issued recall 26V073 because the software remedy was not considered sufficient for all affected vehicles. Recall 26V073 requires complete high-voltage battery replacement. Until that repair is completed, Mercedes instructs owners to park outside and away from structures and limit charging to 80%. My vehicle also shows recall 25V487/MBUSA campaign 2025070009 as pending. This recall concerns a battery busbar connection that could cause sudden loss of propulsion without warning, increasing the risk of a crash. Despite the ongoing fire-risk and loss-of-propulsion concerns, I have not been provided a firm, VIN-specific date for the battery replacement. The safety restrictions significantly limit my ability to use and safely park the vehicle. I am concerned that the permanent remedy remains unavailable while I continue to make lease payments.

I am the owner of a 2023 Mercedes-Benz EQB that has been identified as being affected by the current high-voltage battery safety recall. I recently contacted my authorized Mercedes-Benz dealer regarding the recall and was informed that the recall is currently pending for my vehicle and that the permanent remedy is not expected to begin until approximately December. I understand that the interim safety guidance associated with this recall includes limiting charging to 80% and parking the vehicle outside and away from structures. I have a significant concern regarding the parking instruction. My vehicle is normally parked in an attached garage at my condominium. The garage is connected to my residence, and my HOA does not permit me to park the vehicle outside. Therefore, I do not have a practical way to comply with the instruction to park outside and away from structures. I specifically raised this issue with the service department. I was told verbally that I could continue parking the vehicle in my garage “at my discretion.”

The affected component is the high-voltage traction battery and related battery management and bus-bar connection systems. My vehicle is available for inspection upon request. I am reporting a safety concern because my vehicle is subject to NHTSA Recall 25V050, which identifies a risk that the high-voltage battery could fail internally and cause a fire while parked or driving. It is also subject to NHTSA Recall 25V487, which identifies a defect involving the high-voltage battery bus-bar connection that may cause a sudden loss of drive power without warning. A battery fire could endanger vehicle occupants and people or property near a parked vehicle. A sudden loss of propulsion while driving could increase the risk of a crash. I have not personally experienced a vehicle fire or a sudden loss of drive power. However, I am being asked to continue operating and making lease payments on a vehicle with identified high-voltage battery safety defects and no completed effective remedy available for my vehicle. The currently available guidance limits charging to 80%, which reduces the vehicle’s usable range and practical value. The vehicle’s recall status has been confirmed through NHTSA and Mercedes-Benz recall information. To my knowledge, no dealer repair has been completed that eliminates these safety concerns. The vehicle has not been inspected by police, insurance representatives, or an independent service center in connection with an incident because no crash, fire, or loss-of-power event has occurred. Before any failure, I have not observed a warning lamp, warning message, or other battery-related symptom. My concern is that Recall 25V487 describes a potential sudden loss of drive power without warning, and Recall 25V050 identifies a potential battery-fire risk, including while the vehicle is parked.

Vehicle: 2023 Mercedes‑Benz EQB VIN: [XXX] MBUSA Case #: XXX NHTSA Recall #: 26V073000 Mercedes‑Benz USA has mishandled recall 26V073000 (fire hazard) and left me without transportation. I was told the vehicle is unsafe to drive, which has caused significant anxiety, panic attacks, and ongoing stress because I have no safe way to commute or manage daily responsibilities. MBUSA repeatedly promised a loaner vehicle, but the dealership stated they were never contacted, had no instructions, and had no loaner available. MBUSA later said I could receive a rental car “upon eligible dealership,” but they did not specify which dealership, and after calling multiple Mercedes‑Benz locations, all confirmed they had no information, no authorization, and no process for rental reimbursement or recall support. MBUSA has provided conflicting and misleading information, failed to coordinate with dealerships, and failed to provide transportation during a fire‑hazard recall. This has caused loss of use, mental distress, and safety exposure. I request investigation into MBUSA for failure to properly administer recall 26V073000, failure to provide transportation during a safety recall, and misrepresentation of recall remedies.

There is a recall associated with this model that causes catastrophic stoppage without any ability to drive. My vehicle VIN does not have a recall according to your site. Despite this, my vehicle catastrophically stopped multiple times. It was repaired at least three times and still stopped in the middle of the highway. My partner and I were stopped on I-85S with no ability to move, honk, put on hazards. Cars zoomed past at full speed. I called 911 as we braced for impact. We are lucky to be alive and now suffer from severe trauma. They eventually closed the entire highway and dragged the vehicle to the shoulder almost 30 min later. Mbusa was aware of this defect before rejecting my lemon law claim, but my vehicle was not included apparently. I feel more investigation is needed because it seems very likely my vehicle should be included in the recall. I appreciate your attention to this matter.

Complaint Slight creaking noises when steering. Cause Noises may come from one or more sleeves of the horn contact plate. Remedy Remove the horn contact plate and check the sleeves for noise; see attached video. If necessary, apply lubricant to the sleeves.

Complaint Repeat workshop visit for vehicle vibration while braking from 60MPH. NOTE: Although the symptom is similar to a tire or wheel vibration, it is usually readily noticeable that it is distinctly different if it happens at all times or only while braking. Cause Although the cause of the vibration is most likely due to excessive lateral runout on the rotor or hub/wheel bearing, the system as a whole needs to be checked for other possible contributors. 1. Prior collision damage. 2. Excessive vehicle sitting times without rotating components. 3. Wheel bearing/hub lateral runout. 4. Wheel mating interface has been overtightened (did not follow WIS torque procedures). 5. Mating interfaces have been excessively modified (painted, gouged, bent, etc...). Remedy Read through the entire attached worksheet prior to performing. After performing, please review the final page and perform work accordingly. NOTE: This document is not pre‑authorization or otherwise dealing with warranty. This is intended for diagnostic purposes only. If there are any questions on how to proceed OR The work sheet has been performed and the vehicle has returned with the same concern. Please perform the measurements as seen in the worksheet again and open a TIPS case to the Body, Chassis, and Entertainment team.

Complaint Radio station cover art does not refresh when switching stations. The UI continues to show the old station’s artwork instead of updating to the new one. Cause When a new station change request is triggered, a temporary glitch is causing the Head Unit application to fail to overwrite the previous request. This glitch is causing the cover art mismatch in the Radio application. Remedy Please do not replace any parts. Please update the Head unit software to E505.9

Complaint Clanking noise from the area of the speakers in the doors. Cause Under analysis. Remedy To narrow down the cause, first of all remove the door trim. • If the noise continues to occur even with the door trim removed, then continue the diagnosis working towards the speaker and if necessary, create a TIPS case with an informative video as an attachment. Note: Please refer to this document in the warranty claim and, once diagnosis is completed, select the damage code depending on the component part that is causing the issue. • If the noise stops when the door trim is removed, please proceed in accordance with LI72.10‑P‑067691. Information: In this case, do not use a damage code for the speakers in the warranty claim!

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.
