Tesla (TSLA) has been hit with a recall for 89 of its 2019 Model 3 cars for what many would consider a small infraction. The electric cars were sold without an airbag warning information label on the driver-side sun visor, which the National Highway Traffic Safety Administration (NHTSA) said could increase the risk of injury.

The recall was issued as a violation of the Federal Motor Vehicle Safety Standard under Occupant Crash Protection.

To fix the issue, Tesla Service Centers will inspect the sun visor and, if necessary, replace it free of charge.

Tesla said it will notify affected Model 3 owners in October. Questions about the recall can be directed to Tesla customer service at 1-877-798-3752.

The recall number is SB-19-15-003.

Shares of Tesla stock were up 8.38 percent as of 2:28 p.m. ET on Friday.
