yes i have used 2 cities, 06 model and 08 model both had same problem. 06 was replaced after 140k and 08 was replaced after 150k.
i didnt wait for complete failure, replaced well in time. but it need complete set replacement even if clutch plate is ok and pressure plate has some issue. Both of my cars were creating problem while climbing hilly area. its just like if normal car require 3rpm for climbing a hill the car with issue may require 4 to 4.5k... its not like car will stop climbing.
so its better u ask some honda mechanic to drive ur car and investigate the issue. but commonly hard clutch is the sign of replacement of complete hardware.
