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.

By the year NHTSA received them, which is not the year the failures happened. They peaked in 2023 at 4.

8 6 4 2
18 19 20 21 22 23 24 25 26

This is the year the complaint was filed, not the year the failure happened. The range runs from 2018 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 2018 Mercedes-Benz E 400. 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.

The remedy
MBUSA will notify owners, and dealers will inspect the communication module and activate it, if necessary, free of charge. The recall began March 31, 2021. Letters for the owners of the 9 additional vehicles were mailed July 9, 2021. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2021030005.

STEERING
I am filing this complaint regarding NHTSA Recall 26V216 for my 2018 Mercedes-Benz E 400 4MATIC, VIN [XXX]. On XXX, the recalled driveshaft/universal-joint component failed, rendering the vehicle undriveable. At essentially the same time, the steering became effectively frozen and I could not steer normally. The recall materials I received warned of sudden loss of drive power, but did not warn of possible steering loss. The recall notice did not give an actual earliest repair date. Instead, it stated that I could take the vehicle to an authorized Mercedes-Benz dealer for repair at no cost. My disabled vehicle was taken to Mercedes-Benz of Orland Park on XXX, and I was provided a loaner that

SEAT BELTS
The driver-side seat belt retractor on my 2018 Mercedes-Benz E400 (W213) has failed to fully retract, leaving significant slack across the driver's chest and lap. An authorized Mercedes-Benz dealer has diagnosed the issue as a failed seat belt motor. This component is part of the vehicle's electronic PRE-SAFE system. Because the belt no longer retracts into its stowed position or maintains tension, the vehicle is in a state of non-compliance with Federal Motor Vehicle Safety Standard (FMVSS) No. 209 (Seat Belt Assemblies). Specifically, it fails to meet the retraction requirements necessary to ensure the webbing properly locates on the occupant's body. Furthermore, the failure of the motor
