Some Toyota Corolla owners report experiencing issues with tail lights that stay on continuously, which can lead to battery drainage. This problem may stem from a faulty tail light switch, as some owners have found that the lights remain illuminated even after the ignition is turned off. To address this, it is advisable to inspect and test the tail light switch for obstructions or damage. Additionally, repair solutions may involve replacing malfunctioning components such as the brake light switch, wiring harness, or brake pedal return spring. Troubleshooting steps should include examining the tail light switch, tail light relay, and fuse, as well as inspecting the vehicle's wiring for any potential issues. Prompt resolution of these concerns is important to avoid further complications.

The anti-lock brake system (ABS) may function erratically or illuminate the warning light due a damaged wheel speed sensor. A wheel bearing and/or CV joint with excessive runout can cause the ABS trigger rings to rub against the ABS sensors and damage them.
