if u call the lexus custmer service and tell them your seatbelt needs to be fixed, they will send u to the dealer of your choice, get an estimate and call them back, if u decide to get it fixed, they will reimburse you after u send them the invoice or copy of it......this is what i had to go through, only i havent done it yet, hope this helps you, the number is 1-800-255-3987
