The clutch in my vehicle has just failed at 51000 km and Toyota warranty people reckon its due to abuse, surprise surprise. I smelt this clutch from new and decided it was due to it still burning in. I have only had it on L4 a couple of times and am not in the habit of doing burnouts, but the clutch plate has worn down to the transverse slots. To keep my warranty and I don't know why as they are reluctant to give me warranty on the original clutch, I have had to let them fit original parts, but the part numbers are different, so I expect they know there's a problem and they're not letting on and they are using the consumer as guinea pigs. Oh, by the way, the repair also includes replacing the flywheel, which in my opinion doesn't look too bad.
