BMW is issuing an i3 recall due to risk of neck injury to smaller drivers who don’t wear seat belts. Europe and other markets aren’t affected by this recal.

According to Automotive News Europe a crash test conducted by the automaker showed small adults — at or about 1.5 meters (5 feet tall) and 50 kg (110 pounds) — had an increased chance of sustaining neck damage in a frontal impact crash (according Electrek).

U.S. dealers have been told to stop selling i3 until repairs can be made to the existing 30,542 already in the wild (29,383 of which have been sold).

According to BMW it’s own testing didn’t reveal this issue but more recent tests had.
