C0045 on Saturn

Left rear wheel speed sensor circuit fault (GM)

Severity: Severity not verified — if the car runs badly, have it inspected

The sources describe the fault and lamps but not drivability; ABS and stability systems are safety-critical, so have it checked.

It gets more serious if:

Stop: The red brake warning lamp comes on, the pedal feels soft or low, or steering assist is lost along with the ABS lamp.

Safety-critical system: explanation only, no DIY steps. Source: how we rate severity
