I own a 2022 Mercedes-Benz EQB 350 4MATIC, which is subject to NHTSA Recall 26V073 / Mercedes-Benz Campaign 2026020004 concerning the high-voltage battery. I am filing this complaint because the vehicle remains subject to a known fire-risk defect for which the required recall remedy is unavailable, and Mercedes-Benz USA has been unable to provide a definite repair date. Full details are included as an attachment to this submission

My 2022 Mercedes-Benz EQB 350 4MATIC (VIN [XXX]) is subject to NHTSA Recall 26V073 / MBUSA campaign 2026020004 for a high-voltage battery defect that may cause a thermal event/fire while parked or driving. Mercedes-Benz has determined that the permanent remedy requires replacement of the high-voltage battery, but MBUSA has confirmed that a replacement battery is not currently available for my VIN and has provided no firm repair date. Pending repair, Mercedes instructs owners to limit charging to 80% and park outside rather than in a garage or enclosed structure. These restrictions materially impair normal use. My wife's work requires frequent travel between [XXX] and [XXX], plus secure indoor garage parking at federal government facilities. The 80% charge restriction reduces usable range, while the required indoor parking conflicts with Mercedes' safety guidance. MBUSA has also confirmed in writing that my VIN is currently subject to a recall-related stop-sale and that sale restrictions remain until the recall remedy becomes available. An authorized Mercedes dealer has declined to provide a normal trade valuation because of the recall/stop-sale situation. MBUSA reviewed and denied my repurchase request, offering only possible loaner, storage, or rental assistance. I am filing this complaint to document that the permanent safety remedy is unavailable, the interim restrictions materially impair use, and the vehicle is under stop-sale with no firm remedy date. I request that NHTSA review the remedy delay and whether acceleration or other recall action is warranted. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

PRIORITY COMPLAINT: MANUFACTURER RECALL OBSTRUCTION & COERCIVE SAFETY WAIVER INDUCEMENT. My vehicle is actively subject to NHTSA Campaign 26V073 for a severe high-voltage battery defect causing an immediate fire hazard while parked or operating. Because the manufacturer has no immediate remedy available, I filed an administrative buyback request due to the extreme danger of driving the car. Mercedes-Benz USA (MBUSA) has formally blocked my safety relief by deceptively citing irrelevant Florida Lemon Laws, despite the vehicle being legally purchased in Maryland and registered/operated continuously in Virginia. Furthermore, MBUSA is actively attempting to obstruct the safety intent of this NHTSA recall by trying to bribe me with a $5,500 cash payment in exchange for signing a mandatory "Waiver of Rights" liability release. This release legally bars me from pursuing future recall remedies or lawsuits if the battery catches fire. MBUSA has explicitly stated in writing that if I refuse to sign this total liability waiver, they will offer zero further assistance, effectively forcing me to continue operating a known, catastrophic fire hazard on public roads. I request that NHTSA’s Office of Defects Investigation (ODI) launch an immediate inquiry into MBUSA for utilizing deceptive out-of-state legal tactics and coercive monetary waivers to suppress safety claims and minimize their financial exposure to Campaign 26V073.

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.
