I've taken my vehicle in to the service dealer multiple times since i've purchased the car back in nov. 2016. i noticed a clunking and jolting sensation from my rear axle which i knew was not normal. the dealer after diagnosing the issue told me it is normal and there isn't an issue at all. upon further research online and personal frustration knowing i'm paying for a new car which doesn't feel new at all, i found the attached recall notice. my car has a production date of may 20, 2016 which falls in between the timeline mentioned in the attached recall memo which will require a replacement of the rear differential. also, searching online on the bmw m3 forums, many other owners of this similar vehicle have such an issue and i am worried this might also pose a safety threat to me. for these reasons, i am submitting this form here.
