Tesla in the US is recalling around 9,100 of its 2016 model year Model X vehicles.
An NHTSA report said "the front and center roof cosmetic trim pieces may be adhered to the vehicle without primer." As a result, one or both pieces of trim may separate from the vehicle, the report said.
If a trim separates from the vehicle while driving, it can create a road hazard that increase the risk of a road traffic accident (RTA).
Tesla said a change in process had been made at the supplier in July 2016 to prevent the issue in later models.
Tesla will test the adhesion of the roof trim and reattach the trim pieces as necessary at no cost to the owners of the vehicles.
