There have been some complaints and similar early failures, but many of us are still on the original with 10 times the mileage you have.

Regarding the iPd version, because it is made from urethane and not rubber, it is also stiffer. Some that have made the switch report having more engine vibration in the cabin. But urethane is definetly more durable.

As for warranty, I don't know, but it wouldn't hurt to check with the dealer if you trust them. If you don't trust them, have the service department manager state that the part is not covered by warranty, also stating the mileage, date of complaint, his name and position and his denial of repair under warranty and record him, or type out the claim, have him read it and have him sign it if he refuses to have the repair done whether there is a warranty or not.
