Bayerische Motoren Werke AG has issued a voluntary recall of approximately 106,182 X1 SUVs in the U.S. over safety concerns, according to documents from the National Highway Traffic Safety Administration.

The German carmaker's arm, BMW of North America LLC, will start recalling certain 2016-2019 X1 sDrive28i and X1 xDrive28i vehicles on July 2 due to concerns that the cars' B-pillars do not meet legal requirements.

In the event of a crash, where the occupants head touches the B-pillar, the pillar may not absorb an adequate amount of the impact, increasing the risk of injuries, according to the documents.

The recall was triggered after BMW conducted development tests for occupant protection in interior impact in January, which found that one of the four B-pillar target points in a certain X1 model exceeded the HIC(d), or head injury criterion, value.

The carmaker has not received any reports of any accidents or injuries related to the issue.

BMW centers will fix the affected components for free.
