Anyone having premature wear issues with the leather guide/holder straps for the seat belts? Have had car for 6 weeks and already have two small cuts and rub wear on the seat leather due to the the belt sliding back and forth inside the guide/holder straps. The Lexus dealership has examined and is determining what repair/fix route to take. I question the design and was initially concerned about wear. Unfortunately this did not take long to materialize.
