I was driving down the interstate at the speed limit of 60mph, traffic slowed down then totally stopped. I was at a safe distance to stop, i began tapping on the brakes and i had no brakes. the brake pedal was hard no give in the pedal which caused me to rear end a stopped vehicle doing 60 MPH with me and my son in the vehicle. We went by ambulance to go to the emergency room. The car was declared a total loss by AAA. This happened on September 19th 2023. My safety and my son along with everyone driving on the interstate was at risk because of total brake failure. There were no warning lights present or malfunction indicator lights warnings at all. My son and I, are lucky to be alive.
