My 2022 Mercedes-Benz EQB has an unresolved recall (25V487000) issued July 25, 2025 — nearly 10 months ago — with status still listed as remedy not yet available. The recall is classified as URGENT: FIRE RISK WHEN PARKED on NHTSA's website for my specific vehicle. On May 6-7, 2026 I contacted Mercedes customer service three times and received conflicting safety guidance. Agent 1 told me charging above 80% was acceptable and did not advise outdoor parking. Agent 2 (appointed by a manager) told me to restrict charging and park outside immediately, and escalated to buyback team. Agent 3 called back and said Agent 2 made a mistake and that no restrictions apply. My only available parking is an enclosed residential garage. I have a newborn due any day. Mercedes has failed to provide consistent written safety guidance despite an active federal fire risk classification on my vehicle. I have sent written correspondence to Mercedes Financial Services requesting clarification.

This complaint documents three deficiencies in Mercedes-Benz's recall response for recalls 25V487 and 26V073. First, the BMS software update applied under 25V050 reduced my vehicle's range by approximately 20% and degraded charging performance without adequate disclosure to owners. Second, Mercedes-Benz delayed notification to U.S. owners after fires occurred in already-remediated vehicles in Europe in November 2025. Third, interim measures are inadequate, now confirmed by EVgo independently restricting affected vehicles from their DC fast charging network. A detailed complaint document is attached. Recall numbers 25V487 and 26V073. VIN [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

“My 2023 Mercedes-Benz EQB 350 is subject to NHTSA recall 26V073 involving a high-voltage battery defect that may cause a fire. The manufacturer has instructed me to limit charging to 80% and to park the vehicle outside due to fire risk. This significantly reduces the vehicle’s usable range and creates safety concerns. Due to this 80% charging limitation, the vehicle no longer provides sufficient range for my daily commute and cannot be reliably used for its intended purpose. The manufacturer has stated that the permanent remedy (battery replacement) is not yet available, with an estimated timeline extending into December 2026. I opened a case with Mercedes-Benz on April 3, 2026 (Case #[XXX]), and as of today no case manager has been assigned despite multiple follow-ups. As a result, I am operating a vehicle with a known safety defect that cannot be repaired and cannot be used as intended. This represents both a safety risk and a failure to provide a timely remedy for a safety recall INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting a serious safety hazard involving my Mercedes‑Benz EQB 350. Drive only 1.5 year, Jan 6, 2026, the vehicle suffered an electronic failure at LaGuardia Airport and became completely inoperable. It could not shift into Drive, Reverse, or Neutral and had to be towed to Mercedes‑Benz of Huntington for warranty repair. During service, the dealer performed a wheel alignment on Jan 16, 2026 without my authorization. I had previously declined alignment recommendations because my factory alignment was excellent and my tires were wearing evenly. Within four weeks of this unauthorized alignment (under 1,000 miles), all four tires developed severe inner‑edge destruction. Both rear tires wore down to exposed steel cords, causing air leakage and creating an imminent blowout risk. The front tires also show abnormal inner‑edge wear. The remaining tread on all tires is otherwise good, which is consistent with incorrect alignment rather than normal wear. An automotive engineer confirmed this rapid structural failure is physically impossible through normal driving and is a direct result of incorrect or defective alignment parameters set during the Jan 16 service. This unauthorized and incorrect repair turned my vehicle into a safety hazard for my family. I contacted Mercedes‑Benz USA (MBUSA) immediately and provided photos, documentation, and Case # CMS 20671727. For more than 14 days, MBUSA no response. Representatives gave inconsistent and implausible explanations, including blaming the towing process, which cannot cause this pattern of wear. MBUSA repeatedly redirected me back to the same dealer that performed the unauthorized repair, a clear conflict of interest. Their handling of this case shows dishonesty and an attempt to avoid responsibility, despite clear evidence of a safety‑related defect. I request that NHTSA review this matter as a potential safety defect involving electronic failure, unauthorized repair, incorrect alignment, and rapid tire degradation.

I am reporting a substantial safety defect regarding the high-voltage battery system in my 2023 Mercedes-Benz EQB 350. The vehicle suffers from a 50% loss of advertised range (real-world range of ~95 miles vs. 210 miles advertised) and severe DC fast-charging failures. My VIN is subject to NHTSA Recalls 25V050000 and 25V894 for high-voltage battery fire risk. Per the manufacturer's safety instructions, I have been told not to charge the vehicle above 80%, which further degrades the vehicle’s utility. Additionally, the vehicle is subject to Recall 25V487000 for sudden loss of drive power. Mercedes-Benz has failed to provide a permanent remedy that restores the vehicle's safe operating performance. The combination of fire risk, restricted charging capacity, and unpredictable power loss makes this vehicle unsafe for road use. The manufacturer has formally refused a repurchase despite these documented federal safety violations.

This safety recall is over six months old and is still unresolved. I have not felt safe driving the vehicle on the highway because of the possibility of complete power loss. I have been forced to keep paying lease payments on a car I can't drive and the manufacturer has been unresponsive. When I plug the car in to charge, all the lights in the house dim. My other EV does not do this so it must be a serious problem with this vehicle.

Dear Sir or Madam, Good day. I purchased a New 2023 Mercedes EQB [XXX] from a Dealership in Florida less than 2 years ago. This VIN is associated with NHTSA Recall 2025020001 25V050 Electrical System Battery Fire Risk dated February 3rd 2025. This recall is due to multiple cars spontaneously catching on fire. No cause has been identified or ruled out. Vehicle was previously serviced multiple times for Charging related issues. I spoke to the Dealership about this recall informally. They recommended against charging the car indoors. They said the part for the Recall was not yet available. While the Manufacturer recommends limiting charging in anticipation of a Remedy, no Remedy is available. They plan on providing a software patch, this could very well could be a hardware issue requiring hardware replacement. Having a recall with No Remedy for months puts this car out-of-service. Having a recall with No Remedy for months is a nonconformity. Only being able to charge to 80% is a nonconformity. Car has been out of service for months. The risk is simply too great to charge the car, store the car inside my home, or drive the car. I reached out to the Manufacturer under the Florida Lemon Law (attached) as this has exceeded a reasonable amount of time for a critical life safety repair. Thank you.

Complaint CEL light on with no drivability concerns. Cause Signal timing error. Remedy 167, 465: SW has been released. Update the FSAM to the latest SW version. 290, 118, 243, 247: Software is still in development. This fault code does not cause a drivability concern and will clear itself within 2-3 key cycles. The vehicle can be released back to the customer.

Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The noise is heard once in each instance when changing direction of travel. Note: Sound file in attachment Cause If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to cracking of the microweld between the wheel bearing inner race and the joint housing of the side shaft. Note: The collar nut must always be replaced after being loosened. See also LI33.20-P-078406 Remedy Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows: 1. Remove side shafts 2. Clean contact surface A (see image file in attachment "Outer joint housing before") before coating with Molykote, using "spirit" (free of dust and grease) 3. Coat contact surface A (see image file in attachment "Outer joint housing after") with Molykote and leave to dry for "one hour" in removed condition 4. Reinstall side shafts Note: Before using the antifriction coating (Molykote), stir it or shake it thoroughly for (at least 1 minute).
