“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.”

NHTSA complaint #11728360, filed 2026-03

“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.”

NHTSA complaint #11726005, filed 2026-03

“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.”
