general problems of the 2017 Audi Q5

On 12/13/25 around 8:00am in the morning. I was driving between 20-25 mph and started to brake for the corner stop sign. I applied the break as I normally would however, the car continued to roll and did not respond to my applying pressure to the brake pedal. No matter how much pressure I apply to the brake the car continued to coast without stopping. I continued to press hard on the break and even pumped the break. After 2 to 3 yards of coasting, the car stopped. I continued to drive the car for another 0. 5 miles and the same break problem occurred again. There are no lights indicating problems on my dashboard. The weather was clear and sunny in the morning. There was no rain. There was no snow. All the roads were dry. I took the car to my dealership and they could not find anything wrong. The brake pads were well within the normal safety range at 8 mm. There was no computer system malfunction. They could not give me an explanation. The Audi dealership’s head mechanic said that because my front brake pads and rotor, and my back brake pads were replaced at pep boys two years ago that this could be a reason for the brake failure. Although he was not 100% sure of this. He suggested that I pay $3500 for Audi to replace the current rotors and brake pads despite the original determination that there were nothing wrong with them. The auto mechanic test drove the car with me after the diagnostic evaluation. He could not detect any problems with the brakes no screeching sounds no noises. The anti brake system was working well. To this day, I still do not feel safe driving this car for fear that the incident with the brake failure will happen again.
