特斯拉宣布召回2016年4月之前生產的12.3萬輛Model S轎車，以修理動力轉向部件。這是特斯拉歷史上規模最大的召回事件。

特斯拉表示，召回的目的是更換該部件，這是源于“極度的謹慎，以確保顧客的安全和放心”。

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

近一年前，特斯拉曾召回5.3萬輛Model S和Model X轎車，以解決停車制動問題。

特斯拉發言人在一份聲明中表示：“美國政府發現，Model S是所有測試車輛中致人受傷可能性最小的，我們也在不斷地測試和升級Model S，以確保它成為世界上最安全的轎車之一。”

該發言人稱，特斯拉尚未接到任何與上述問題有關的事故或受傷報告。特斯拉還表示，本次召回不涉及Model X SUV和新的Model 3轎車。更換該部件一般需要一小時。

該公司在寫給受影響車主的信中稱，宣布召回的原因是它發現在非常寒冷的天氣下動力轉向螺栓會過度腐蝕，特別是在道路上頻繁使用鈣鹽或鎂鹽，而非氯化鈉，也就是食用鹽的地區。

特斯拉在信中表示，考慮到這些車輛以后可能會在高腐蝕環境下行駛，它計劃在全球范圍內為所有氣候條件下的全部早期Model S更換動力轉向螺栓。

該公司指出，即使該螺栓失靈，駕駛者仍可控制汽車方向。但由于動力轉向功能減弱或完全喪失，駕駛者需要用更大的力氣轉向。這種情況下，在低速行使或側方位停車時車輛將變得更難控制，但對高速行駛車輛因其轉向時只需要有限的力量，所以沒有明顯影響。（財富中文網）

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.
