2003 Lexus Is

MY CAR HAS 51000 MILES ON IT AND I'M TOLD MY ALTERNATOR SHOULD BE REPLACED. I TOOK MY CAR FOR ONE THINGS AND THE DEALERSHIP FOUND 4 DIFFERENT ISSUES WHICH 2 OF THE ISSUES I AM AWARE OF. GRANT YOU ALL THE PARTS IN MY CAR ARE THE ORIGINAL PARTS. I SERVICE MY CAR ACCORDING TO LEXUS 25,000 - 75,000 MILES SERVICES. HOW CAN I WELL KEPT AND SELDOM DRIVE VEHICLES HAVE AN ALTERNATOR ISSUE? ON FEBRUARY 7, 2003, THERE WAS COMPLAINTS OF THE (BULLETIN#:T10001308) CD BECOMING JAMMED IN CD CHANGER. IMPROVEMENTS WERE MADE TO THE IS 300 CD CHANGER MECHANISM BUT I WASN'T NOTIFIED. I TOOK MY CAR TO WESTSIDE LEXUS REGARDING AN ONGOING DASHBOARD MELTING SITUATION AND CD PLAYER ISSUE. LEXUS FINALLY AGREED TO REPLACED DASHBOARD AFTER 3 YEARS AND I AM GRATEFUL BUT THE CD CHANGER JAMS NOW. IF I HAVEN'T DONE MY RESEARCH I WOULDN'T KNOW THERE WAS INITIAL COMPLAINTS REGARDING THE CD CHANGER. OVER THE MONTH-TO-MONTH WEIRD CD SOUND OF TUMBLING THEN PLAYING IT PROGRESSIVELY GOTTEN WORSE. MY 5- DISC CD PLAYER WILL NOT PLAY CDS AT ALL AND SOUND IS CD TUMBLING AROUND IN THE PLAYER. WESTSIDE LEXUS STATED I NEEDED TO REPLACE THE CD PLAYER AT $500.00 AND I SHOULD NOT HAVE THE ISSUE AT ALL. I SHOULD HAVE BEEN NOTIFIED AS SOON AS THE ISSUE WAS ADDRESSED. I SHOULDN'T HAVE TO PAY $500.00 FOR A 2003 ISSUE. *TR
