Well I've had the first wear related failure on the ES. I've had some big things done under warranty due to TSBs but the dealer found the rear main seal was leaking and needed to be replaced. $1,900.
Luckily I have the extended warranty! Turned out to be a good purchase there lol. At least it got some use, its only got 4k miles to go until it expires.
Oh well, my first wear related failure didn't occur until ~95k miles. Not too shabby,
