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...
