The headlights continously and irregularly flicker between high and low beam while driving at night. I have no control over it and cannot turn off the high beams when they activate. This is highly annoying to drivers ahead me, as they believe I am trying to get their attention (or be obnoxious). In these times and the legalization of open carry weapons in the state of Florida, this can be highly dangerous if the wrong person is aggravated by unintentional signaling. I have already had issues on

Several times I have been stopped at a red light, and my parking break will come on without me engaging it. I was almost hit by other vehicles the last time my vehicle did this.

Because I had not manually engaged my parking break, my vehicle would not allow me to disengage the parking break until after it finally read that I engaged it. It took me 10 minutes of having to turn my car off and back on a
