The designs of some hybrids are able to remove a lot of parts that normal ICE-only cars have.

The design of most Toyota hybrids is quite simple, there are two electric motors and one gasoline engine coupled by a simple planetary gear set. This eliminates the need for a mechanical transmission -- varied wheel speed is accomplished by simply varying the relative speeds of the electric motors. Contrary to a popular misconception, there is no mechanical cone-and-belt CVT in Toyota hybrids, like people might be familiar with in other CVTs. Also, because the engine is linked to the drive motors, this eliminates the need for a starter motor. And because all of the engine accessories are electric on most Toyota hybrids (because they need to operate when the engine is off) there is no accessory belt.

These components (drive belts, transmissions, starter motors) aren't uncommon issues in ICE-only vehicles, so this does translate to improved reliability and lower maintenance.
