Tesla said in its safety recall report that in the vehicles, a first-row seat belt was disconnected from its pretensioner anchor as part of a necessary step to perform a repair. But the seat belt may not have been reconnected to its pretensioner anchor properly after the repair was made.
U.S. highway safety regulators opened an investigation into possible Tesla seat belt issues in March. Notification letters will be mailed to owners who have vehicles related to the recall. Tesla said that it will perform free inspections and connect both first-row seat belts to their pretensioner anchors where necessary. If the seat belt can't be connected to the pretensioner anchor properly, the seat belt assembly will be replaced for free.
