Two problems related to front suspension control arm have been reported for the 1997 Saturn SL. The most recently reported issues are listed below.
During oil change discovered that front subframe was rusted through at control arm attachment point, drivers side. Car was removed from service as this is a major safety issue affecting suspension and steering. Tried to find a used subframe but all in local auto parts recyclers were just as badly rusted.
Severe rust out of the suspension sub-frame (engine cradle) along the left side, particularly at the lower control arm mount pocket. This condition was caught before the left front lower control arm broke loose due to the rusted sub-frame. Rust condition was confined to the left side of the sub-frame with no apparent issue with the right side or cross beams. Brought to Saturn's attention but concern was denied as the "vehicle is out of warranty". Saturn never addressed the issue that the sub-frame is a component that should last the lifetime of the vehicle.
