Deaths

A complaint is an unverified account by the person who filed it, not a finding of fault. One complaint is one ODI number, which is how NHTSA counts them.

A recall is the manufacturer conceding a defect, and the repair is free. Whether one covers your particular car is a question only its VIN can answer, because a campaign covers a production range rather than a model year.

This is the year the complaint was filed, not the year the failure happened. The range runs from 2025 to 2026 , the last of them a part year, which is why its column is drawn faint.

Crash test ratings

NHTSA New Car Assessment Program

NHTSA has not crash tested the 2022 Mercedes-Benz EQB 300 4Matic. Its New Car Assessment Program tests a selection of each year's vehicles and does not reach motorcycles, heavy trucks, motorhomes or most low-volume models, so an absence here says nothing about how the vehicle would perform. It is not a low score.

What owners have reported about this vehicle is below, and it is a different question: a crash test measures what happens to the people inside in a controlled impact, while a complaint records what broke during ordinary use.

ELECTRICAL SYSTEM
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.

If this is your car and a dealer keeps failing to fix it, your state's lemon law may require the manufacturer to replace it or buy it back. How many repair attempts it takes, and how long you have to file, is set by the state you bought in and by nothing on this page.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
