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.

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.

The contact owns a 2022 Mercedes-Benz EQB 300 4MATIC. The contact stated that while driving approximately 45 MPH, there was an abnormal grinding sound coming from the rear of the vehicle, and the vehicle lost motive power. The contact stated that several unknown warnings illuminated. The MIL was illuminated, and the battery symbol was displayed. The messages “Reduced Drive System Performance" and "Towing not Permitted" were displayed. The accelerator pedal was depressed; however, the vehicle failed to respond as needed and stalled. The contact attempted to restart the vehicle, but the vehicle failed to restart. The vehicle was towed to a local dealer, where it was diagnosed, and several error codes for engine performance were retrieved. The vehicle was not repaired. The contact stated that the dealer had retrieved the same error codes one week prior when the vehicle was taken to be repaired under NHTSA Campaign Number: 25V050000 (Electrical System). The manufacturer was informed of the failure. The failure mileage was approximately 115,000.
No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
