NHTSA ODI 11709515

My GX550 is vibrating at all speeds. I took my GX550 in for service on [XXX] at Butler Lexus in Union City, GA, because of the vibration in my GX. They did a wheel alignment and a force road wheel balancing but this did not solve the problem. On September 3, 2025 I took my GX550 to Discount Tires in Douglasville, GA, where they took off all the old weight including the new ones that were added by Butler Lexus. I found no improvement as I drove home. I took my GX550 back to Discount Tires, I asked them to check the tires and wheels. I was informed by one of the tech at Discount Tires that the my wheels are marginally out of round and I should let Lexus know to check the suspension. I was told by Butler Lexus service department that Discount Tires was grasping at straws. I spoke with Lexus Corporate September 19, 2025, they informed me that Butler Lexus Service department informed me that my vehicle is suppose to operate with vibrations, that could felt in the steering wheel and seats. I asked for someone from Lexus to come out and inspect the vehicle. At first I was told that Lexus doesn’t do that. Then I was told she would check into it. Also Lexus never addressed the the transmission hard shifts that I reported. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
