The leading corrections to electroweak precision observables in the MSSM with non-minimal flavor violation (NMFV) are calculated and the effects on M W and are analyzed. The corrections are obtained by evaluating the full one-loop contributions from the third and second generation scalar quarks, including the mixing in the scalar top and charm, as well as in the scalar bottom and strange sector. Furthermore the leading corrections to the mass of the lightest MSSM Higgs-boson, m h , is obtained. The electroweak one-loop contribution to M W can amount up to 140 MeV and up to 70 x 10-5 for , allowing one to set limits on the NMFV parameters. The corrections for m h are not significant for moderate generation mixing.
