2025 Acura MDX Suspension Problems

on 8/24, I purchased an acura mdx 2025 technology package.We drove home from the dealer, my mother heard a rattling noise but thought it was the car seat making the noise.The next day,I heard the noise again,it was coming from the right, rear back,I checked,and saw the wheel liner loose and thought the noise was being cause by a loose liner.My mother said we had to go back to the dealer on 8/31 to pick up the wheel lock and weather mats and we would have them check the liner.As the week went by,the noise was more often.On the way to the dealer, we could hear the noise after every bump or turning right.We gave this information to the dealer,we said we thought it was a loose liner but were not sure anymore as the rattling was more often.We did not feel safe driving home.They provided us a loaner and said they would look into it.On 9/4 they sent a text that the rear sway bar link was faulty, the part was ordered and the car should be ready by Friday.My mom emailed them to ask if by faulty,they meant it was loose or broken,they checked and said it was broken.It was expressed to them that this was concerning because it was a brand new vehicle,that we felt blessed that we decided to leave the car,had we driven back home, God knows what could have happened since a broken link can cause you to lose control and get into an accident.We asked if they would report it to the manufacturer or NHTSA? They did not reply. But text a day after stating that we must have gone through a pothole at high speed or hit something,and we were liable for the cost.After my mother sent an email and spoke with them saying that if it was not caused by us,that if the issue was there,was it caused during transporting the car from The manufacturer to the dealer?they said that the car was fixed and there would be no charge but kept insisting that we were at fault,that it happens alot,where people walk out of the dealer and come back with something broken the next day. (more to say but no space)
