My wife was driving to the store on surface streets at about 9am on a clear morning. At a stop light, waiting for the green. After light turned green she accelerated at a normal rate. Midway through the intersection (at about 10 mph) the vehicles emergency braking system engaged for no reason slamming her to an immediate stop. There were no obstructions in front or to either side of the vehicle. There was another car behind her that almost rear-ended her. My wife’s safety was at risk because she could have been involved in a collision which may have resulted in injuries to my wife and or others and she was sitting, shaken in the middle of an intersection thinking that someone had hit her from behind. The vehicle has not been taken to the dealership yet. My wife states that the vehicle displayed many indicator warning lights on the instrument panel after it stopped including the Advance Warning lights, but instead of just showing a collision warning with the car, 3-double bars and lanes in red, it showed (in red) a car with 4-double bars all around the vehicle, no lanes and the vehicle shut off. The car started again when she took her foot off of the brake.
