Hybrids by definition have internal combustion engines also. Moreover, the ones that are in most implementations start and stop with large frequency. That cycling is a stress on the internal moving parts, as well as the starting motor, the associated ignition parts, and the flywheel it meshes with.
And hybrids have to have very sophisticated control systems, and the more the complexity, the more possibility of component failure. Very pricey components.
Honda discontinued its Accord Hybrid. The remaining hybrid vehicles are the Prius, the Civic, the Insight, the 100K Lexus 460h, the Saturn small SUV, the Chevy Malibu, the Ford Escape, and the GM Yukon full-size SUV.
