Sunroof randomly exploded while driving on the highway. Nothing hit it or otherwise caused the breakage. I was travelling at a normal constant speed on a normal temperature day. Glass got all over me and inside the sunroof's opening mechanism. Lexus replaced the glass but refused to repair the housing / opening mechanism.

The actuator on the driver door went out and in 2025 and had to get replaced. I was not able to lock or unlock the drivers side door. All the doors would lock and unlock. Just the other car the front passenger doors actuator lock went out. It is doing the same, will not lock or unlock. I have to do it manually.
The rear middle seat child seatbelt retractor on my 2020 Lexus GX 460 failed internally - the belt became stuck and would not retract, rendering the child safety restraint position unusable. The failure was severe enough that the dealership (Tri-County Lexus, Little Falls, NJ) determined the vehicle was unsafe to drive with the affected seating position in use and grounded the vehicle pending repair. Lexus Corporate authorized replacement of the belt assembly (Part #73320-35010-A4) at no cost under an internal...

goodwill case, which itself indicates recognition that this was a component failure rather than normal wear. I am filing this report so the defect is on record, given the safety-critical nature of a child restraint failure.
Subject: Urgent Safety Concern - Driver Seatbelt Malfunction I am writing to formally report a serious safety concern regarding the driver-side seatbelt in my vehicle. The seatbelt does not retract properly and frequently becomes caught in the door. In addition, the retractor fails to pull the seatbelt back completely, leaving slack in the belt. More concerning, there have been multiple instances where the seatbelt did not properly engage or lock when braking was applied, even though it was securely fastened. I...

brought the vehicle to the dealership for inspection, but I was advised that this condition is "normal." I strongly disagree with this assessment. A seatbelt that does not retract correctly or fails to lock during braking poses a significant safety risk and does not meet expected safety standards. This issue raises serious concerns about the reliability of the restraint system in the event of an accident. I am requesting a thorough inspection of the driver-side seatbelt system, including the retractor mechanism, and that any defective components be repaired or replaced immediately. Please document this concern formally and provide written confirmation of your findings and recommended corrective actions. I am very concerned for my safety and expect this issue to be handled with the urgency it deserves.
The driver's seat is making cracking, clicking, popping, and creaking noises from the lower seat frame, seat rail, or mounting area where the seat attaches to the vehicle body. The noise is most noticeable during braking, acceleration, turning, driving over uneven roads, and when shifting body weight in the seat. It feels as though the seat has movement or play, as if the seat rails, frame, or mounting bolts may not be fully secure. This is a safety concern because the seat is part of the occupant restraint system...

and is critical for proper seat belt positioning and airbag protection. If the seat frame, rails, or mounting hardware are loose, damaged, worn, or improperly secured, the seat could shift during a sudden stop or collision. In an accident, movement of the seat could reduce seat belt effectiveness, alter occupant positioning relative to airbags, increase the risk of impact with the steering wheel, dashboard, door, or center console, and increase the likelihood of head, neck, chest, back, pelvic, or leg injuries. Unexpected seat movement could also affect driver control immediately before or during a crash. This should not be treated as a simple interior rattle. The seat mounting bolts, rails, locking mechanisms, adjusters, frame components, and floor mounting points should be fully inspected for looseness, improper torque, wear, cracking, or structural failure. I have also found numerous similar owner complaints online from Lexus GX owners reporting clicking, cracking, rocking, or shifting driver seats that feel loose or unstable. Based on forum discussions and owner reports, there appear to be dozens of similar complaints, suggesting this may not be an isolated issue.
