“February 2026, our vehicle was recalled for the Battery Issue. We contacted Mercedes Benz USA LLC, several several times ,we filed a claim, they said it would be for a Buy Back, we can not get anyone to call us back to resolve this issue, we contacted the dealer that we purchased the vehicle from and they will not call us back at all. …”

“Mercedes built the car with a faulty battery and now they want to provide an update to the car that makes it worse: reduced battery life and slower charging times. So I have to choose between only charging my car to 80% or taking their update which makes my car worse. How can the NHTSA allow that to be the solution to the problem?”

NHTSA complaint #11704610, filed 2025-12

“THere is a global recall of the 2023 EQB 250 vehicle due to an unfixed battery issue. (It is the second recall for the same issue fur my vehicle). However, the manufacturer has not sent me any warning about the latest battery recall (critical risk of fire). The dealer is only engaging over voice calls and refusing to put any acknowledgement of the recall or the risk in writing. There is no remedy in sight, and they are unable to exchange the impacted battery either. …”

“We purchased a 2023 Mercedes EQB (EV) 2 years ago. The car is part of a recall in which we are advised to not park near other cars and not charge at home. Thus making the car essentially not useable unless we take the risk. We are driving it, knowing that we could catch fire. We are parking it and charging it in our garage, knowing it could catch fire. We have no choice as Mercedes has not offered any loaner or rental option so we can park this car until the recall or buyback is complete. …”

NHTSA complaint #11724702, filed 2026-03

“The battery in this car can catch fire at any time while parked. The dealership would not take the car to inspect, repair or replace the battery because there is no remedy available at this time. The recall information go back to January 2026 with no remedy or resolution available period. Instructions say I can charge it only up to 80%. I have to make adjustments to my daily routine. Instructions say I have to park it away from buildings. This car is a serious safety hazard for humans and buildings.”
