Agency examining Tesla complaint alleging unintended acceleration

DETROIT — The U.S. government’s auto safety agency is looking into allegations that all three of Tesla’s electric vehicle models can suddenly accelerate on their own.

Brian Sparks of Berkeley, California, petitioned the National Highway Traffic Safety Administration asking for an investigation. An agency document shows 127 owner complaints to the government that include 110 crashes and 52 injuries.

The agency said it will look into allegations that cover about 500,000 Tesla vehicles including Model 3, Model S and Model X vehicles from the 2013 through 2019 model years. The agency’s investigations office will evaluate the petition and decide if it should open a formal probe.

“I am concerned that these complaints reflect a systemic defect that has not been investigated by NHTSA,” Sparks wrote to James Owens, the acting NHTSA administrator. “I am also concerned that these potential defects represent risk to the safety of Tesla drivers, their passengers, and the public.”

Messages were left Friday seeking comment from Tesla.

NHTSA is already investigating three December crashes involving Tesla vehicles in which three people were killed. The agency’s special crash investigations unit sent teams to Gardena, California, and near Terre Haute, Indiana, to probe two fatal crashes. Another crash in Connecticut also is under investigation.

Frank Borris, a former head of safety defect investigations for NHTSA, said the number of complaints cited in the petition is unusual and warrants further investigation.
