When Mr's clutch dies, there's no way I'll let Hyundai do the job. I complained about the clutch way back at around 15,000k and they said it was normal, clearly they don't know what a good clutch feels like.
Not covered under warranty anyway, and whenever a worn out clutch is replaced you don't simply replace the driven plate.
Here in Aus clutch kits come with new driven plate, pressure plate and throw out bearing.
Flywheel is removed and re-surfaced, spigot bearing checked and lightly greased.
All friction surfaces degreased and scrupulously clean re-assembly.
Then you'll have a chance of a decent clutch, not some jumpy thing as the result of a half done job.
