The TSB (Technical Service Bulletin) for the 2017 Niro's experiencing breaking door handles calls for ALL 3 door handles except the driver door, to be replaced. Ours were replaced in September when the vehicle was 2 months old. Recently, our front passenger door handle AND end cap broke off. Obviously the "fix" is NOT fixing the problem. I read somewhere that it was an over torquing issue on the assembly line............. well, after the "fix" if the handles are still breaking off, the problem must be something other than over torquing.
