The car basically blew up on the highway at rush hour. BMW knows of this issue with this model and has some of their other models under a recall for this very thing.

M440i years to avoid — and the clean ones
Complaints per model year. More reports usually means more cars on the road as well as more trouble, so read the crash and fire columns alongside the count.
| Model year | Complaints | Top system | Crashes | Fires |
|---|---|---|---|---|
| 2025 | Steering | — | — | |
| 2021 | Engine | 1 | 1 |
The same model year, different builds
Every complaint carries the first 11 characters of the VIN — plant, year, body and engine. That is a production series, and complaints are spread across them very unevenly.
| Measure | Value |
|---|---|
| Distinct production series | 3 |
| Average complaints per series | 1.3 |
| Worst single series | 2 complaints |
| Average age at failure | 1.3 years |
A model average of 1.3 hides a worst series at 2. Enter a VIN above to see the numbers for that exact build instead of the model as a whole.

How we count
Every figure here comes from complaints owners filed with NHTSA — 1,100,006 of them, covering 1,982 models built between 1981 and 2026.
A complaint is an unverified report: someone wrote down what happened to their car. It is not a confirmed defect and not a recall. What makes the volume useful is the pattern — when thousands of owners of the same build describe the same failure, that is a signal no marketing brochure will give you.
Two things we do that the source does not. First, we compute the age of the car at the moment of failure from the incident date and the model year. Second, we group complaints by the first 11 characters of the VIN — the production series — so a bad plant run does not disappear into a model-wide average.
