NHTSA Complaint #11672906 — 2021 HYUNDAI VENUE

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.
