The NHTSA announced an open investigation into certain Tesla (NASDAQ:TSLA) Model X vehicles due to seat belt failures.
The regulatorâs Office of Defects Investigation (ODI) stated that it has received two recent complaints regarding âa failure of the front seat belt to remain connected to the seat belt anchor pretensioner while driving with seat belts worn properly in 2022 and 2023 Model Year Tesla Model X vehicles.â The vehicles were delivered in that condition, according to the complaints. 
âIn both cases, the pretensioner and the linkage were not properly connected during assembly, resulting in friction fit maintaining the connection between the two until eventual separation,â the investigation notice reads. âThe linkage and the pretensioner suddenly separated when the force exerted on the linkage overcame the resistance of the friction fit while the vehicles were in motion. Both known incidents occurred at low vehicle mileage. Neither incident involved a vehicle collision.â
A total of about 50,000 vehicles are estimated to be covered under the probe. 
The pedestrian alert sounds for the Model X remain under investigation, as does a probe opened by the ODI earlier in the month regarding reported detachments of Model Y steering wheels. The model has received a total of 36 official complaints, per the NHTSA. 
A total of 11 recalls have been issued in relation to the Model X, most recently in due to Tesla's (TSLA) Full-Self Driving Beta issues.
