  • 2023 MERCEDES-BENZ EQB 300 4MATIC
    - Seattle, WA

    I received an Important Safety Recall notice (NHTSA Recall ID: 26V073) from Mercedes-Benz USA in March 2026 regarding my 2024 EQB (VIN: [XXX] ). The notice states that the high-voltage battery may fail due to an internal short circuit, potentially causing a vehicle fire while parked or driving. No incident has occurred. This complaint is filed because no remedy is available and no timeline has been provided by the manufacturer. Mercedes-Benz has advised owners to limit charging to 80% and to park outside while awaiting battery replacement parts. This interim guidance creates an additional hardship: my vehicle is garaged in ZIP code 98119 (Seattle, WA), where property crime is documented at over 50% above the national average. The manufacturer's guidance forces me to expose a $55,000+ vehicle to elevated theft and vandalism risk indefinitely, through no fault of my own. I am requesting NHTSA pressure Mercedes-Benz to accelerate parts availability and provide affected owners with a loaner vehicle or covered parking reimbursement until the remedy is performed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    The contact owns a 2016 Mercedes-Benz Metris. The contact received a notification of NHTSA Campaign Number: 22V482000 (Tires); however, the part to do the recall repair was not yet available. The local dealer was contacted; however, the recall repairs were denied, and the contact was asked to take the vehicle back to the original dealer who sold the vehicle. The contact reached out to several other local dealers; however, the assistance was provided due to the vehicle having approximately 18inch rims. The manufacturer was made aware of the issue, but no assistance was provided. The contact had not experienced a failure.

  • 2021 MERCEDES-BENZ GLC 300
    - Trussville, AL

    While driving in my neighborhood at 25 MPH, my Mercedes GLC300 suddenly lost power and the check engine light illuminated. My car would no longer exceed 25-30 MPH, but I drove it straight to the dealership and they said it was a faulty cylinder head and will cost $10,000 to fix! After intense negotiations, they agreed to fix it for $4,205.58, which was better, but still, that’s a lot to pay for a manufacturer’s defect! My car is a 2021 with only 67,540 miles on it.

  • 2021 MERCEDES-BENZ GLE 580
    - Buffalo Grove , IL

    My Mercedes GLE 580 experienced a complete failure of the 48V battery system due to the exact defect outlined in NHTSA Recall Campaign 24V207 (defective 48V ground connection causing high resistance and fire risk). The official status for my VIN shows 'Recall Incomplete.' The vehicle is currently at Mercedes-Benz of Barrington. The dealership is actively refusing to remedy this safety recall under warranty and is attempting to charge me $5,313 out of pocket for the battery replacement. Furthermore, the dealership refuses to submit the correct diagnostic error code (B183371) to my extended warranty provider to block coverage. My family has been left completely stranded without transportation for 7 days, and the manufacturer refuses to provide a loaner vehicle while the vehicle is unsafe to drive due to this fire hazard recall.

  • 2020 MERCEDES-BENZ E 450
    - NEW HYDE PARK, NY

    Rear glass window on convertible soft top is prematurely separating/delaminating from top assembly on 2020 Mercedes-Benz E350 convertible with under 8,000 miles. Glass is integrated into the convertible top and failure may lead to reduced rear visibility, possible glass detachment, water intrusion, and safety hazard while driving. This appears premature and inconsistent with expected vehicle life.
