If we include old cubes, it would have to be the Dayan Panshi. It would break corners constantly and it basically killed the Dayan 3x3 brand after it had huge success with the guhong and zhanchi.
Honorable mention is the Maru 4x4 which could have misaligned centers. That probably doesn't even make sense but it's like if you don't have a fixed 2x2 corner so an internal middle "slice" can be unaligned. Even the Rubik's 4x4s never had that problem (they were ball core I think)
