We just purchased a Certified Pre-Owned 2020 RX350, 27,000 miles. We have put about 400 miles on it the first week we owned it. My son tested it and helped pick it for mom. When I drove the first time I felt the brakes had a pulsation when pressed. We live in a small town and the nearest dealer is 80 miles away. Brakes and rotors not covered in the Certified warranty, so no loaner if we take it to the dealer to get checked.
Is there a downside to taking it to my local tire/brake shop where I have had service for 20 years. Afterall, pads and rotors are usually just pads and rotors.
