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.

Which system owners named

POWER TRAIN 4 · 24%
TIRES 4 · 24%

Red marks a system with a recall campaign against it. One complaint can name several systems, so these add up to more than 17.

When the complaints arrived

By the year NHTSA received them

By the year NHTSA received them, which is not the year the failures happened. They peaked in 2025 at 6.

8 6 4 2
23 24 25 26

This is the year the complaint was filed, not the year the failure happened. The range runs from 2023 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 2023 Mercedes-Benz E 450. 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.

It could have very dangerous if I were driving a little faster and fortunately there was no other damage to the car or other persons. In each case, I hit a small pothole, and the tire blew out, flat to the ground. Because these are run flat tires, on the first 2 incidents I was able to drive home and to the dealer for tire repair/replacement. The third one was so bad that I could not drive all the way home and had to get towed. But all 3

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.
