Brakes I wasn't able to stop when I got to the intersection. My emergency brake system never turned on and stop me from hitting the rear of the ambulance. I had called my sales man that I buy my cars from about a week after buying the car and advised him that something popped up on my dash and he adviced me to take the car back to the dealer to have it checked out so I did and they said there was nothing wrong with it. So I left and about 2 or 3 weeks later it came back on and before I could take it back to dealer I had the accident. Also what popped up on my dash was that my view was being obscured but it was day light perfectly clear. I do have a picture of what popped up on my phone.
