The reigning World Cup champion tallied a combined time of 1 minute, 48:71 seconds, 0.08 seconds ahead of Vonn. Finn Tanja Poutianen placed third.
Vonn clipped a gate near the bottom of the course but maintained her balance and made it to the podium.
"It would have been nice to get the win again, but I had a big mistake at the bottom and Maria had a really good run so it's tough to say if I would have beaten her without that mistake," Vonn said.
