美国联邦汽车安全监管机构周二对特斯拉车门潜在缺陷展开调查。据报道，该问题曾导致多名家长因儿童被困后座而被迫破窗施救。
美国国家公路交通安全管理局表示，在收到九起因电池电压过低可能导致电子门把手失效的报告后，已对2021款特斯拉Model Y车型展开初步调查。
亿万富翁埃隆·马斯克（Elon Musk）旗下的公司已在车辆内部安装了手动车门释放装置，但美国国家公路交通安全管理局（NHTSA）指出，儿童可能无法触及或不知如何操作这些装置。在四起案例中，家长不得不打破车窗才能进入车内。
针对该汽车制造商最畅销车型的调查，源于近年来多起关于特斯拉车门开启故障的报道——事故后断电时，这些故障有时会将驾驶员困在燃烧的车辆中。
今年4月，一名大学篮球新秀表示，他在撞树后特斯拉赛博卡车起火且车门无法打开时，为逃生而“与时间赛跑”。南加州大学球员阿利贾·阿雷纳斯（Alijah Arenas）在事故后陷入短暂昏迷，他称自己在车内浓烟弥漫时通过用水瓶浇淋身体得以幸存。
去年，一名特斯拉Model 3驾驶员因被困车内被烧至面目全非，其亲属起诉埃隆·马斯克的公司存在过失与欺诈行为。诉状称，尽管特斯拉车辆涉及200起起火事故，该公司仍未修复其指控的车门设计缺陷。该案目前仍在洛杉矶高等法院审理中。
美国国家公路交通安全管理局（NHTSA）表示，此次调查仅针对车辆外部电子门锁的可操作性，而非内部，因为这是唯一无法通过手动方式开门的情况。但该机构同时称，将持续关注车内人员被困（即其所谓的"困人事件"）的相关报告，并将视情况采取进一步措施。
目前机构调查涉及约17.43万辆中型SUV。
该机构表示，此类事件似乎发生在车辆电子门锁供电电压不足时。现有维修记录显示，事故发生后均更换了电池。在提交事故报告的车主中，无人曾在车门外部把手失灵前收到蓄电池低电压警告。
美国国家公路交通安全管理局（NHTSA）表示，其初步评估将重点关注问题的范围和严重程度，包括已上报情况所带来的风险。
该机构的调查还将评估特斯拉为门锁供电的方式以及相关电源的可靠性。
特斯拉还因一项名为**召唤**的技术受到美国国家公路交通安全管理局（NHTSA）调查，该技术允许车主指令车辆自动驾驶至其所在位置接载乘客。据报道，这一功能曾在停车场引发多起轻微碰撞事故。去年，NHTSA对特斯拉240万辆汽车的驾驶辅助功能展开调查，起因是多起在雾天及其他低能见度条件下发生的撞车事故，其中一起导致行人死亡。今年8月，NHTSA又启动另一项调查，旨在查明特斯拉为何未按要求及时向该机构报告撞车事故。
马斯克正面临压力，需要证明其驾驶辅助功能的最新进展不仅修复了已报告的故障，还使其性能卓越到驾驶员甚至无需再看向窗外。他近期承诺，到明年年底前将让数十万辆此类自动驾驶特斯拉汽车及特斯拉机器人出租车驶上道路。
随着特斯拉今年年初开始的销量暴跌几乎没有减缓迹象，这一努力变得更加紧迫。马斯克因支持特朗普总统和欧洲极右翼政客及其政策，激怒了传统上具有环保意识的特斯拉客户群体。上周六，他在伦敦一场反移民集会上对抗议者表示“暴力将降临到你们身上”，并称“要么反击，要么死亡”。
周二午后交易时段，特斯拉股价上涨逾2%，报419.25美元。此前一天，由于马斯克购入价值10亿美元股票的消息刺激，该股已出现大幅上涨。

Federal auto safety regulators opened an investigation Tuesday into possible defects in Tesla doors that have reportedly left parents with children trapped in the back seat and forced to break windows to get them out.
The National Highway Traffic Safety Administration said the preliminary inquiry is focused on 2021 Tesla Model Ys after receiving nine reports of electronic door handles not working possibly due to low battery voltage.
The company run by billionaire Elon Musk has installed manual door releases inside the vehicles, but the NHTSA noted that a child may not be able to reach or know how to operate the releases. In four cases, the parents had to break the windows to get inside.
The investigation into the carmakers most popular model comes after numerous reported incidents in recent years of other problems with opening Tesla doors, sometime trapping drivers in burning vehicles after accidents and a loss of power.
In April, a college basketball recruit said he was fighting time trying to get out of his Tesla Cybertruck that had caught fire after he had crashed into a tree and was unable to get the doors open. The University of Southern California player, Alijah Arenas, who was induced into a temporary coma after the accident, said he stayed alive by dousing himself with a water bottle as smoke filled the vehicle.
Last year, relatives of the driver of a Tesla Model 3 who was trapped in his car and burned beyond recognition sued Musks company for negligence and fraud for failing to fix what they called a design flaw in the doors despite what they said were 200 fires involving its cars. The case is pending in Los Angeles Superior Court.
The NHTSA said the investigation is focusing only on the operability of the electronic door locks from outside the vehicle, not inside, as thats the only instance in which there is no manual way to open the door. But it also said it will continue to monitor reports of people stuck on the inside what it calls entrapment and will take further action as needed.
The current agency investigation covers about 174,300 of the midsize SUVs.
The agency said the incidents appear to occur when the electronic door locks receive insufficient voltage from the vehicle. It said that available repair invoices indicate that batteries were replaced after such incidents took place. Of those who reported incidents, none saw a low voltage battery warning before the exterior door handles became inoperative.
The NHTSA said that its preliminary evaluation will look at the scope and severity of the condition, including the risks that come from the conditions that have been reported to them.
The agencys investigation will also assess the approach used by Tesla to supply power to the door locks and the reliability of the applicable power supplies.
Tesla is also under investigation by NHTSA for a summon technology that allows drivers to tell their cars to drive to their location to pick them up, a feature that has reportedly led to some fender benders in parking lots. An inquiry into driver-assistance features in 2.4 million Teslas was opened last year after several crashes in fog and other low-visibility conditions, including one in which a pedestrian was killed. The NHTSA in August launched another investigation to determine why Tesla apparently has not been reporting crashes promptly to the agency as required.
Musk is under pressure to show that the latest advances in its driver-assistance features have not only fixed such reported glitches but have also made them so good that drivers dont even need to look out the window anymore. He recently promised to put hundreds of thousands of such self-driving Tesla cars and Tesla robotaxis on roads by the end of the next year.
That effort has become more urgent as a plunge in Tesla sales that began this year shows little sign of abating. Musk has angered the traditional environmentally conscious Tesla customer base by supporting President Trump and far-right politicians in Europe and their policies. On Saturday, he told protesters at an anti-immigration rally in London that violence is coming to you and you either fight back or you die.
Tesla stock rose more than 2% to $419.25 in afternoon trading Tuesday after a jump the day before on news that Musk had bought $1 billion worth of shares.
