特斯拉召回12.3万辆Model S，原因如下

特斯拉宣布召回2016年4月之前生产的12.3万辆Model S轿车，以修理动力转向部件。这是特斯拉历史上规模最大的召回事件。

特斯拉表示，召回的目的是更换该部件，这是源于“极度的谨慎，以确保顾客的安全和放心”。

上周四宣布召回后，特斯拉股价在市后交易中下跌8.38美元（下跌3.15%），报266.13美元。

近一年前，特斯拉曾召回5.3万辆Model S和Model X轿车，以解决停车制动问题。

特斯拉发言人在一份声明中表示：“美国政府发现，Model S是所有测试车辆中致人受伤可能性最小的，我们也在不断地测试和升级Model S，以确保它成为世界上最安全的轿车之一。”

该发言人称，特斯拉尚未接到任何与上述问题有关的事故或受伤报告。特斯拉还表示，本次召回不涉及Model X SUV和新的Model 3轿车。更换该部件一般需要一小时。

该公司在写给受影响车主的信中称，宣布召回的原因是它发现在非常寒冷的天气下动力转向螺栓会过度腐蚀，特别是在道路上频繁使用钙盐或镁盐，而非氯化钠，也就是食用盐的地区。

特斯拉在信中表示，考虑到这些车辆以后可能会在高腐蚀环境下行驶，它计划在全球范围内为所有气候条件下的全部早期Model S更换动力转向螺栓。

该公司指出，即使该螺栓失灵，驾驶者仍可控制汽车方向。但由于动力转向功能减弱或完全丧失，驾驶者需要用更大的力气转向。这种情况下，在低速行使或侧方位停车时车辆将变得更难控制，但对高速行驶车辆因其转向时只需要有限的力量，所以没有明显影响。（财富中文网）

Tesla is recalling 123,000 Model S sedans—its largest recall ever—to fix a power steering component in cars built before April 2016.

The recall to retrofit the component was issued out of “out of an abundance of caution to ensure the safety and peace of mind of our customers,” Tesla said.

Tesla shares fell $8.38, or 3.15%, to $266.13 in after-hours trading on Thursday, just after the recall was announced.

Nearly a year ago, Tesla issued another recall for 53,000 of its Model S and Model X carsto fix a parking brake problem.

“Model S was previously found by the U.S. government to have the lowest probability of injury of any car it has ever tested, and we continue to test and update Model S to ensure is among the safest vehicles in the world,” a company spokesman said in a statement.

Tesla has not received any reports of accidents or injuries relating to the issue, the spokesman said. The recall doesn’t affect Model X SUVs or its new Model 3 electric vehicles. The retrofit will typically take around an hour, the company said.

Tesla issued the recall after it discovered excessive corrosion in the power steering bolts in very cold climates, particularly area where they is frequent use calcium or magnesium road salts rather than sodium chloride, or table salt, the company said in a letter sent to affected owners.

Tesla plans to replace all early Model S power steering bolts in all climates worldwide to account for the possibility that the vehicle may later be used in a highly corrosive environment, the company wrote.

Tesla says even if the bolts fail, the driver would be able to steer the car. However, it would require that the driver use extra force because the power assist feature are either reduced or fail altogether. Under such conditions, the car becomes more difficult to drive at low speeds and to parallel park, But it does not materially affect control at high speed, for which only limited steering wheel force is needed, Tesla wrote to customers.
