My first replacement was at 4,000 miles and it was a revision E which initially felt tougher. After that I was extremely careful but the combination of the heat and the occasional brush against my jeans caused another wear spot. I am now at 15,000 miles. I doubt mileage will mean much because the overstretched material is very weak especially in hot weather. The smallest scratch will start the failure which will keep getting larger.Let us know how the G revision goes. I am hoping this gets resolved.
Also how many miles did it hold up for What ever the current revision is on your vehicle.. ?
Maybe someone here can start the Spread sheet and start tracking some data after how many miles of use they are starting to see the wear happening on the material.
In order to preserve the new replacement I have started using "Easy Entry" to move the seat back and the yoke up and forward.
Fingers crossed that revision G has a more durable material.
