We report the results of a search for the decay B0 -> K*+ K*- with a sample of 454 +/- 5 million BBbar pairs collected with the BaBar detector at the PEP-II asymmetric-energy e+e- collider at the Stanford Linear Accelerator Center. We obtain an upper limit at the 90% confidence level on the branching fraction for Br(B0 -> K*+ K*-) < 2.0 x 10^{-6}, assuming the decay is fully longitudinally polarized.

Charmless B→VV decays under SU(3)_F show 5.2σ tension for ρ,K* modes and >7σ when ϕ and ω are included, while isospin-only ρK* fits remain acceptable.
