There has been a lot of good news these days.TeslaOnce again, facing the question of security risks.

The National Highway Traffic Safety Administration (NHTSA) said on January 17 that it would begin reviewing a petition from independent investor Brian Sparks claiming that Tesla, Inc. 's car had an unexpected acceleration hazard that could affect 500000 Tesla, Inc. cars produced between 2013 and 2019, the Consumer report magazine's website reported.

The petition quoted many media reports about crashes caused by accidental acceleration of Tesla, Inc. 's electric vehicle, including 127cases.ComplaintsAccording to the report, 123 Tesla, Inc. cars and 110 crashes were involved and 52 people were injured. According to the complaint report, when car owners try to park Tesla, Inc. 's vehicles in a garage or by the side of the road, the vehicles will suddenly accelerate, causing a crash if they occur while driving or when using a driving assistance system.

One owner said the 2015 Tesla, Inc. Model S 85D began to accelerate suddenly when it was closed and locked, crashing into a parked car. Another owner said that when he was driving Tesla, Inc. 's car close to the garage door, the vehicle suddenly accelerated forward, crashing two garage doors in succession and didn't stop until he hit the concrete wall.

So far, Tesla, Inc. has not commented on this. According to CNBC, NHTSA, which has the power to enforce a recall of vehicles and spare parts, will decide whether to launch a formal investigation after evaluating the contents of the petition.

This is not the first time Tesla, Inc. has been questioned about security risks.

In May last year, Tesla, Inc. upgraded his battery management software in response to several "spontaneous combustion" incidents. In September of that year, NHTSA received a petition claiming that Tesla, Inc. had a potential flaw in the fire caused by the car crash. A month later, NHTSA said it was evaluating whether Tesla, Inc. should recall 2000 electric vehicles with safety concerns, rather than issuing software upgrades.

In addition, NHTSA is also investigating the accident of a Tesla, Inc. Model 3 colliding with a fire engine on December 29, 2019. This is the 14th accident involving Tesla, Inc. in the NHTSA's special accident investigation program, which may have activated Autopilot or other driving assistance systems while driving.

However, according to Tesla, Inc. 's 2019 auto safety report, Tesla, Inc. electric vehicles with autopilot assistance systems on average have an accident for every 4.91 million kilometers. By contrast, data recorded by NHTSA show that there is an average of one car accident for every 770000 kilometers in the United States. In addition, Tesla, Inc. Model 3 also received an overall rating of 5 stars in the NHTSA 2019 safety rating.
