Blue Whale Motor, February 18, according to foreign media reports, in the past few months after receiving hundreds of complaints, the National Highway Traffic Safety Administration announced on February 17, local time, the investigation into the accidental braking problem after Tesla electric vehicles opened Autopilot, involving 416,000 Model 3 and Model Y.
The National Highway Traffic Safety Administration's report shows that the Defect Investigation Office has received 354 complaints from Model 3 and Model Y owners about accidental braking problems in the past 9 months, involving Model 3 and Model Y models in 2021 and 2022, and the report said affected users referred to the problem as "ghost brakes."
Tesla electric vehicles with "ghost brakes" are equipped with advanced driver assistance systems, that is, Tesla's Autopilot automatic driver assistance system, and accidental braking also occurs after opening Autopilot. The report said that when using the Autopilot automatic driving assist system function, the vehicle brakes unexpectedly when driving at high speeds, and in the absence of any prompts or warnings, rapid deceleration may occur randomly, often multiple times in a driving cycle.
Some industry insiders have analyzed that the "ghost brake" failure that caused Tesla to encounter the NHTSA investigation this time is mainly due to its cancellation of the millimeter-wave radar equipped with the vehicle. At the same time, the pure visual autonomous driving perception system that it insists on building is also difficult to get rid of.
According to incomplete statistics, in the past six months, Tesla has recalled a total of about 15 times, including 11 times in the United States, 3 times in China, and 1 time in Canada, involving four of its mass-produced models.
At present, the relevant local departments have conducted a preliminary investigation into the accidental braking problem, determined the scope and severity of the potential problem, and comprehensively assessed the potential related safety problems.
Affected by this, on February 17, the US stock market closed, Tesla's stock price closed at $876.35 per share, a decline of 5.09%, and the latest market value was $905.7 billion.
