Example complaints
Electrical system: “For two months my EQB has been signaling high voltage when I charge it also now I’m having a problem connecting the plug to charge my car it shows red light has faulty it’s at the shop for a week now and I haven’t gotten updates about my car the cameras as well are turning black not working.”
NHTSA complaint #11641571, filed 2025-02Engine: “My vehicle is a 2024 Mercedes-Benz EQB 300. Despite the nationwide recall (NHTSA 26V073000) for high-voltage battery fire risk, the manufacturer is providing conflicting and dangerous safety information. I was verbally instructed by dealership representatives to park my vehicle outdoors and limit charging to 80% to avoid a fire hazard. …”
NHTSA complaint #11724420, filed 2026-03Other or unknown: “Although I have not experienced safety issues myself, this exact model+year combination has been recalled more than once: 2024 Mercedes EQB 300 4matic, and when I searched by my VIN it shows recall. I’m very concerned if my car is mistakenly not included - what if it has battery issue/fire risk but I am not aware? This poses huge safety risk on day to day driving. I request an investigation on this particular VIN and reasons of why it is not in the recall list despite all infos match.”
