The contact owns a 2022 Mercedes-Benz EQB 300 4MATIC. The contact stated that while his son was driving 28 MPH and depressing the accelerator pedal and making a right turn, the battery message was displayed and the vehicle decelerated. The vehicle was pulled over to the right side of the road, and the contact selected the option on the radio, and the message disappeared immediately. The contact continued driving and then reversed, and the message was displayed again, and the brakes independently engaged. The contact associated the failure with NHTSA Campaign Number: 26V073000 (ELECTRICAL SYSTEM). The failure had occurred on several occasions. The approximate failure mileage was 19,489.

he vehicle intermittently fails to shift from Park (P) to Drive (D). Recently, the car was completely immobilized for over 6 hours because the gear would not engage, making it dangerous and unpredictable to drive. Additionally, the vehicle has experienced multiple charging failures where charging repeatedly cuts off unexpectedly. A formal diagnosis from Mercedes-Benz of Cary confirmed a front axle drive unit failure and high-voltage insulation faults, triggering codes U041A00 and P154800. Crucially, the certified technician noted a grinding noise coming from the axle drive module, which occurs specifically when slowing down. These symptoms perfectly mirror the known manufacturing defects outlined in NHTSA Recall 24V331 for the 2022 EQB front axle drivetrain failure. Despite clear connections to documented, catastrophic high-voltage safety hazards, Mercedes-Benz USA has denied warranty coverage and is demanding an outrageous repair cost of over $14,000 from the owner.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, ENGINE
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.

This urgent safety issue with the high voltage battery on the 2022 Mercedes EQB has been known to Mercedes since at least July 2025. As of May 15, mercedes tells me I will have a repair scheduled by December 30, 2026. They offer no explanation for the delay. This is unreasonable and unacceptable. I am requesting that the NHSTA inform Mercedes that they must do better to eliminate this known fire hazard, and inform me of the penalties you can impose on Meercedes if they do not complete this recall in a timely fashion.

Manufacturer Recall Number2026020004 NHTSA Recall Number26V073 Recall StatusRecall Incomplete, remedy not yet available Summary Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year ("MY") 2022-2024 EQB (243 platform) vehicles, a risk of fire of the high-voltage battery (EB330) cannot be ruled out. Due to the combination of certain production and use conditions, an internal short circuit of a battery cell in the high-voltage battery, might lead to a thermal event. Subsequently, an increased risk of a fire cannot be ruled out An authorized Mercedes-Benz dealer will replace the high voltage battery. Customers will be instructed to charge their vehicle's battery to a maximum of 80% state of charge until the remedy is performed.Out of an abundance of caution, customers are additionally advised to park their vehicles outside.

The vehicle is subject to Safety Recall 26V073 (High-Voltage Battery Fire Risk). Since March 2023, at 6,177 miles, the vehicle has experienced recurring powertrain and battery malfunctions. Despite 11 total service visits and 8 specific attempts to repair the battery management system and powertrain modules, the defect remains unresolved. The vehicle currently displays sudden red dashboard warnings stating "Engine will not restart" and "Malfunction" while driving at highway speeds and on sideroads. These incidents cause a sudden loss of confidence in the vehicle's propulsion and power. According to the manufacturer’s recall chronology, these warnings indicate a potential internal battery short circuit, which could lead to a thermal event/fire. Safety is compromised as the vehicle may stall in high-speed traffic, and the manufacturer has directed that the vehicle be parked outside and away from structures due to fire risk. The manufacturer has admitted that previous software "remedies" were failed attempts and that a hardware remedy (battery replacement) is unavailable for at least 9 months (December 2026) . This leaves the driver (owner) in a dangerous, non-conforming vehicle for an unreasonable duration. All malfunctions have been confirmed by authorized dealership service centers (Invoices #685069 and #687727 are attached as references).

We are currently under NHTSA Recall ID: 26V073 and Mercedes-Benz has not given us a reasonable timeline with which they intend to remedy the recall. We are currently unable to drive the car safely and unable to park the car safely without the risk of fire. To not have any answers as to when this recall will be remedied is unacceptable.

Mercedes previously issued a software update for the battery fire risk, but we have received a letter more than a year later stating that this fix was not adequate. We pursued a vehicle buyback due to the safety risk this presents to my family, and Mercedes vehemently stated that the issue was resolved and the vehicle did not qualify. The vehicle is an inherent risk to my family's safety if it may just catch fire at any time.

My vehicle will not hold a charge. Since buying this car. I have been doing a lot of charging instead of driving. With normal charging, it takes approximately the whole day (24 hours) to have the vehicle charge over 80% and after that, the charge will not hold for a long time. This happens every time.
