2021 Hyundai Venue Brakes

Last week I was driving my daughter’s Venue and the brakes became hard. Crunching noises. I suspected I had dropped my water bottle and perhaps it rolled under the brake pedal. It was hard to depress I heard the same crunching noises as I tried to use the brakes. Drove home 1.5 miles slowly and it continued to occur all the way. I had it towed to the dealer. Been there a week and they cannot replicate it. I mentioned I had an oil change 48 hours earlier. They said the oil had been over filled which they corrected. I contacted Jiffy Lube and they took exception to this. Idk what to do. I am nervous to drive it or return it to my daughter. Dealer wants me to pick it up. We are at an impasse.

The contact owns a 2021 Hyundai Venue. The contact stated while driving at various speeds and attempting to depress the brake pedal, the pedal would travel to the floorboard. Additionally, there was an abnormal vibration in the pedal. The contact stated that the stability control warning light was illuminated. The vehicle was not taken to a local dealer to be inspected. The manufacturer was informed of the failure and the contact was awaiting a response. The failure mileage was approximately 23,000.
