2020 Lexus GX problems

Filed Sep 4, 2026 · Seat belts · NJ

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.
