As soon as I left my driveway this morning the car started beeping and the brake warning light was on. As soon as I stop the beeping stops but the warning light stays on. The car seems to think my ebrake is engaged but it isn't. I tried pulling it up and down thinking it may recongnize that the brake was down but with no luck. Is the sensor bad or could it be that the ebrake is no longer disengaging? Has anyone else experienced this?
