My car has spun it's crank hub and the car is only 3 -4 years old most people i know with the same car as mine just different year has had to replace the crank hub as well. it's a common failure on these cars and would like nhtsa to recall this common problem that's been happening since 2015. when the crank hub fails from timing going off countless issues can arise which can cause engine to be replaced which is a very costly repair. it would a piece of mind to have the f80/f82/ f83 recalled it would be a piece of mind for our community. now how it happened was, i was driving one night coming from work around 7:30 pm on the highway i was exiting the highway because that was the exit for me to get off to head home so i downshifted, car rev matched automatically in sport mode and next thing i know i hear a pop noise. the car shuts off while rolling on the off ramp, lucky i was slowing down already heading to a stop i rolled off to the side and had car towed to a german engineering shop. the next morning i went to the shop to hear what was the issues, the crank hub spun which means the timing was thrown off by a little. that cost was over 3k to fix. this happened last week on thursday december 12th, 2019. so the car is still being fixed, there were other cars there getting crank hub fixed for either preventative maintenance or the same issue happened to mine. but i'll be getting my car by the weekend i was told. i will post documentation/ pictures with another form once car is finished. i do plan to buy another f80 or f82 as a gift for my mother but this issue i hear happening everyday makes me hesitant to get another one.. another issue, i feel as if the manual transmission for the f8x series have bad 1st gear synchros because my first gear pops out and no one knows the issue. all my friends that have a 6 speed manual f8x have the same first gear popping out problem.
