Most Recent Complaints

#11718986 | ELECTRICAL SYSTEM | | N/A miles
Sometimes we feel like sparking noise when driving from battery i dont know wat is that properly.bt my wife drives a lot she told me every time.she dnt feel safe sometimes
#11702632 | ELECTRICAL SYSTEM | | N/A miles
I own a 2023 Mercedes-Benz EQB 300. After the dealership performed the recall Update Battery Management System Software – Campaign 2025040005 / 25V050 / 25P5496507, my vehicle immediately experienced a significant loss of battery performance. Problems that began right after the recall update: Driving range decreased by approximately 25–30 miles. DC fast-charging speed dropped from about 100 kW before the update to a maximum of around 80 kW after the update. Vehicle was performing normally before the recall software was installed. This update appears to have negatively affected the performance, efficiency, and charging capability of the high-voltage battery. Mercedes has not yet provided an explanation or solution. I am requesting that NHTSA investigate whether the recall update is improperly derating or limiting the high-voltage battery and whether this safety recall is causing reduced functionality for other EQB owners.

#11697675 | ELECTRICAL SYSTEM | | N/A miles
In December 2024, I brought my 2023 Mercedes-Benz EQB to Mercedes-Benz Beverly Hills for scheduled service. They told me the vehicle had a recall and booked me for a future appointment, but I was unable to attend because I was out of town. I called the dealer multiple times afterwards to reschedule, but they never told me the reason for the recall or explained the safety risk. I recently checked my VIN myself and discovered that the recall is related to a high-voltage battery defect that may cause sudden loss of power and battery fire. I was never properly informed by Mercedes-Benz about this serious safety hazard. I rely on this vehicle to transport my two young children. This is an electric vehicle with a battery fire risk and possible loss of power at highway speeds. Mercedes-Benz has not provided a remedy, repair, loaner vehicle, or timeline. I am requesting NHTSA assistance to ensure Mercedes-Benz addresses this safety recall or provides a safe replacement or loaner vehicle until repairs are available.
