※ [本文轉錄自 car 看板 #1RtLwoey ] 作者: Scape (缺鈣缺很大) 看板: car 標題: [新聞] BMW M3、M4北美召回，更換新的傳動軸時間: Sat Nov 3 16:39:09 2018 原文連結： https://www.autoblog.com/2018/10/31/bmw-m3-m4-recall-driveshafts/ 原文內容： BMW M3 and M4 recalled, in need of new driveshafts 2016-2017 M cars could experience 'loss of propulsion' The turbocharged M3/M4 twins were the most powerful of the 3 Series-based M cars ever made when they came out. Now it appears all that extra torque from the turbocharged motor could be a bit too much for some of the driveshafts, because a weakness there is prompting BMW to recall 2,660 of its M cars. Of those, 1,456 are M3s and 936 of them are M4s, both for model years 2016-2017. There are even some of the rare M4 GTS coupes involved in the recall as well. The driveshaft flange is reportedly too weak for the 406 pound-feet of torque (or more) subjected to it, and may fail over time. Upon failure, the connection between the driveshaft and the flange could break, "resulting in a loss of propulsion," according to the National Highway Traffic Safety Administration. Fixing it will require a new driveshaft for all the cars, done free of charge. Those who have already replaced their driveshafts will be reimbursed for the work. Randomly losing propulsion could result in a dangerous situation, but BMW says it's unaware of any crashes or injuries caused by the defective flanges. 心得/說明：召回的車型是16-17年的M3/M4，其中M3 召回了1456輛，M4 936輛還有一些較稀有的M4 GTS 也被召回召回的原因是傳動軸太弱，與法蘭盤連接處可能會斷裂需要更換新的傳動軸記得這批M3/M4 的傳動軸都是碳纖維的(之前有報導說新款車要換成鋼製) 台灣應該也有人買到同批M3/M4 吧... -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 1.34.252.81 ※ 文章網址: https://www.ptt.cc/bbs/car/M.1541234354.A.A3C.html
