• Crank hub slipping All years One source so far

  On CarComplaints, two owners of 2016 M3s raise it. One reports the crank hub spinning and the engine dying while coasting toward an intersection, at about 20,000 miles; the other calls the hub a ticking time bomb likely to fail just outside the warranty.
