The front automatic seat belt commonly sticks in its track and fails to properly operate, causing a safety issue. This also causes an electrical draw that will drain the battery and may cause the car not to start. The dealer may cover (or partially cover) the repair costs.

Driver's belt sticks and a clicking can be heard while driving when it does completely seat while driving. After shutting off car a clicking can be heard from the outside. Battery will be flat by morning.
