2009 Mazda CX-7 Brakes Problems

I purchased a car from Best Buy Motors in Spanaway, WA on [XXX]. Three days later I took the car in for an oil change and my mechanic cited safety issues and identified the rear brakes were faulty and deemed them a safety hazard. I repaired the brakes because I did not want to continue driving them under those conditions. My mechanic stated that the dealership was wrong for selling the car with the brake pads so thin and worn. My bill for the brakes and oil change was $778.28. I called the dealership and asked them to pay for the "parts" $388.08. They talked to the mechanic and came back with parts for $119. They could have fixed the brakes for that amount before they sold it to me. My issue is that they had the car on the lot for over 6 weeks and allowed people to test drive the car with faulty rear brakes. That is hazardous to me and to people who are on the road. I still have the rotors and pads that were taken off the car. I showed the old parts to another mechanic and he agreed that it was indeed a safety hazard to be driving with them in that condition. I only asked them to pay for the parts, not the labor and they refused. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I PURCHASED A NEW VEHICLE AND NOTICED SQUEAKING IN THE REAR WHEELS WHEN APPLYING BRAKES. I TOOK THIS INTO THE DEALER AND WAS FIRST TOLD THAT THIS WAS NORMAL. THEN THE DEALER SANDED DOWN THE ROTORS AND BRAKE PADS AND SAID IT WAS OKAY. THE SQUEAKING PERSISTED AND I WENT BACK TO THE DEALER. THEY REPLACED ROTORS AND SAID IT WAS FIXED. THE SQUEAKING STILL CONTINUED. I CONTACTED MANUFACTURER AND THEY DIDNT RESPOND FOR WEEKS. I CONTACTED DEALER AND THEY SAID THEY COULDNT DO ANYTHING FURTHER. I WENT BACK TO DEALER AND THEY SAID THEY COULD SAND DOWN BRAKE PADS AGAIN. THEY TOOK FOR ANOTHER TEST DRIVE AND IGNORED MY CALLS FOR WEEKS. FINALLY I TOOK TO ANOTHER DEALER PER MANUFACTURER INSTRUCTION AND VEHICLE HAS BEEN IN SHOP FOR A WEEK. *TR
