I figured it was a phantom light, but it has started to stay on longer lately.
Can anyone offer a suggestion on what might be causing this strange situation?
Thanks for your help.
Check the brake fluid level and inspect the front brake pads. Worn pads can lower the fluid so it shifts away from the level sensor during a hard left turn and triggers the brake light. Also inspect the fluid-level sensor or switch, and have the brakes checked if the pads are worn or squealing.
A 1999 Dodge Grand Caravan owner reported the dash brake light coming on briefly during hard left turns, never on right turns, and staying on longer over time. One reply with the same van said worn front pads can drop the brake fluid so it shifts during a turn and trips the level sensor, which may be on the right side of the reservoir; a bad switch is also possible. Another owner of a similar Caravan said worn, squealing front brakes caused the same left-turn warning and recommended a brake inspection.
