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 8
