• Low brake fluid level: Check the brake fluid level in the reservoir under the hood. If it's low, top it off with the recommended brake fluid specified in your owner's manual.
• Faulty E-brake switch: The E-brake switch, which is located under the center console, might be faulty, causing the light to come on even when the E-brake is not engaged. Check the connection and replace the switch if necessary.
• Faulty brake light switch: The brake light switch, located near the brake pedal, could be faulty, causing the E-brake light to illuminate. Inspect the switch and replace it if damaged or malfunctioning.
• Electrical issue: There might be a loose connection, a short circuit, or another electrical problem that's triggering the E-brake light. Have a qualified mechanic inspect the wiring related to the E-brake system.
• ABS (Anti-lock Braking System) malfunction: If your vehicle is equipped with ABS, a malfunction in the ABS system could also cause the E-brake light to come on. This usually requires professional diagnosis and repair.
Since the issue is intermittent and appears to be unrelated to the actual engagement of the E-brake, it's best to have your vehicle inspected by a reliable mechanic who can properly diagnose and fix the problem. Ignoring this warning light could indicate an underlying issue that may compromise your safety on the road.
