One problem related to seat belt has been reported for the 2000 Saturn LS. The most recently reported issues are listed below.
The whole subframe on my 2000 Saturn Ls is rotted so bad that I can't even drive the vehicle. It started with my car not starting and putting it up on a lift to see what the problem was. That not starting problem is a bad resonator, but in the process the subframe was found to be seriously rotted away.
