I recently was involved in a collision where my car going at 30 mph collided with. Car that was completely stopped that I unfortunately didnât see Iâve previously been warned by the safety system where itâs saved me by first audio warning and then immediately breaking allowing me to avoid collision unfortunately prior to the accident I never had any issues but occasionally noticed that the Audi Pre Sense could be triggered occasionally when I was driving on the highway and the police were using radars to control speeding cars I could occasionally see the light safety system alert me but almost immediately disappeared Iâm assuming the radar could affect the safety system since the indicator picked up that a few times but only popped up warning and said it was currently restricted but never did anything as Iâm sure it knew it wasnât needing to break however I have concerns about the safety system and itâs lack of safety especially the last incident where I was traveling in a completely straight direction and hit the car in front of me that was stopped in traffic the safety system never worked properly and I seem to have the same issue even now with the system but wonât work and doesnât do anything to alert me to potential problems anymore Iâm not sure the account cause of the failure but Audi of America hasnât been really responsive with my safety concerns and wonât return my phone calls or email Iâve recently been notified of a potential class action
