NHTSA Complaint #11600246 — 2023 LEXUS RX

This 2023 Lexus RX350H and several others vehicles of the same model and year and the 2024 year model have made sporadic roof popping noises that appear to be causes from heat expansion and/or flexion of the vehicle. I have taken this vehicle in a total of seven (7) times to two different Lexus dealerships. The first (4) trips to the dealerships they were unable to duplicate the vehicle, because they didn't keep it long enough. The last three (3) trips to Sewell Lexus in Fort Worth they heard the roof noises and were unable to fix the problem. On the last visit the Lexus Representative supervised the repair and determined that the problem was what the called roofs bows or what appears to be roof supports had come detached from the inside of the roof. The dealership supposedly re-glued the bows/supports and claimed the vehicle was repaired. Three days later the car made the popping noise and has done it often own since then. I have personally driven a similar model loan vehicle from the dealership and it made the popping roof noise also. I have read recent threads this year on the ClubLexus forum site where other Lexus owners of this model vehicle (Both 2023 and 2024) have stated that their vehicle has also made the roof popping noise. I believe this is a Lexus manufacturing defect that they have not been able to fix and have ignored my suggestion that this is a Lexus model defect and also my request for a replacement vehicle, since they haven't been able to fix it. They took the car apart inside to the bare metal the last time they worked on it. This noise has happened when driving, turning corners and when parked and not running.
