For the past month, my blindspot indicator has gone off with no other vehicles around. A message pops up on my dash which shows an indication of a collision and then a loud thump noise which causes my car to break (not by me) and yellow arrows appear on both sides of the dash (side-by-side) at which time the car looses power. I called the dealership and they cannot get me in until next week. Meanwhile, my anxiety is through the roof each and every time I drive. The first time this happened was on the highway, I had to throw my hazards on as the vehicle behind me was way too close. This occurs often, if not almost daily now in my area (where there is only one lane each way) and in the rural streets of my neighborhood.
