The U.S. auto-safety regulator is asking Tesla to provide information over a growing number of customer complaints that the company’s most popular vehicles brake for unexpected reasons as it intensifies its monthslong scrutiny of the issue.
The National Highway Traffic Safety Administration said Friday that it issued a letter to Tesla last month after receiving 758 reports of unexpected braking, often called “phantom braking,” in some Model 3 sedans and Model Y crossover vehicles. The figure is about double the number of complaints NHTSA earlier this year said it had received. The auto maker has until June 20 to respond, NHTSA said.
