The U.S. National Highway Traffic Safety Administration (NHTSA) has closed its engineering analysis into steering control failures in 2023 Tesla Model 3 and Model Y vehicles. The investigation found a risk of overvoltage breakdown on the motor drive component of the electronic power steering system's printed circuit board, which could lead to a loss of power steering. Tesla initiated a recall in February 2025, addressing the issue through a software update (version 2023.38.4) that began rolling out in October 2023. Following the software update, NHTSA observed a significant decrease in related complaints and has therefore decided to close the investigation, though monitoring of the recall's effectiveness will continue.
