One problem related to engine rattling and whining sounds has been reported for the 2000 Saturn LS. The most recently reported issues are listed below.
2000 Saturn l series timing chain failure. Meticulous maintenance and sensible driving still have left me with a broken timing chain, bent valves(interference motor, I'm told) and basically a busted motor. Big problem not covered by a recall for the 11/00 to 01 l series. Bunch of bull recall isn't for my car when it's the exact same design separated by only months in production ! normal driving down road and awful rattle sound and motor was stalled and so was I .
