The U.S. National Highway Traffic Safety Administration (NHTSA) said on July 2 it closed its 2022 preliminary evaluation into nearly 695,000 Tesla vehicles after finding that reports of unexpected braking had dropped significantly and presented a low safety risk.

The regulator said the number of complaints fell sharply after Tesla introduced software updates in early 2022.
