2015 CR-V drive shaft vibration

November 11 2014 I bought an all wheel drive CR-V and returned. There was a drive shaft vibration. The dealer gave us another brand new SUV, there was a drive shaft vibration problem again. Went to the dealer for repair, part was replaced but problem continues. Went back to the dealer so it can be fixed again but unfortunately dealer can't fix anymore. The problem is with Honda. And Honda doesn't have a solution for the problem. 3 Months and no solution.
