New problem started this week, whereas when I pull the emergency brake handle to release it, the warning light above the trip computer does not turn off. And when I put it in Drive, the trip computer also says the pedal is not released. And when the car is in motion, it dings at me. As far as I can tell though, the E-brake is fully disengaged. Thoughts? Coincidentally, and possibly related, I found this rubber bumper on my floor the same day the issue started. What is it and where does it go?
