  We study the dark matter (DM) direct detection for the models with the
effects of the isospin-violating couplings, exothermic scatterings, and/or the
lightness of the mediator, proposed to relax the tension between the CDMS-Si
signals and null experiments. In the light of the new updates of the LUX and
CDMSlite data, we find that many of the previous proposals are now ruled out,
including the Ge-phobic exothermic DM model and the Xe-phobic DM one with a
light mediator. We also examine the exothermic DM models with a light mediator
but without the isospin violation, and we are unable to identify any available
parameter space that could simultaneously satisfy all the experiments. The only
models that can partially relax the inconsistencies are the Xe-phobic
exothermic DM models with or without a light mediator. But even in this case, a
large portion of the CDMS-Si regions of interest has been constrained by the
LUX and SuperCDMS data.
