Heat does not work in Hybrid Vehicle. Prevents windshield from being able to be defrosted in winter. Should be covered under warranty, however when I took it to the dealer they report that multiple Volvo have this problem and there is a part shortage. Because of this problem, the vehicle is unsafe to drive the vehicle in the winter because it won't generate enough heat to melt the snow and ice that hits the windshield.
