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.
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. "The sheer number of complaints would certainly catch my eye."
Borris, who now runs an auto safety consulting business, told Associated Press that Tesla owners communicate with other owners on internet forums and social media, and that could influence the number of complaints, he said. He said the timing of the petition is good, because the agency needs to do a "deeper dive" into Tesla safety.
Some of the unintended acceleration complaints, which have yet to be verified by NHTSA, allege that the cars' electronics malfunctioned.
To be fair, Brian Sparks, the man asking for the investigation, "is currently shorting Tesla stock, but has hedged his bets and been long shares of Tesla in the past".
