One problem related to brake disc caliper has been reported for the 2001 Saturn LS. The most recently reported issues are listed below.
Driving down the highway when I notice a burning rubbery smell. Stop the car and check all tires, the left driver rear is extremely hot and smelly, the others are not. Drove immediately to the Saturn dealership and was told I needed a new brake calliper as it was disinigrating and the smell was from the brake pads getting so hot, they were melting. I also had to have the brake pads changed do to the fact the caliper binding locked onto brake slider and would not free up. Had I continued to drive it locked up, it could have gotten so hot, it would have started a fire under the wheel well.
