I oftenly have strong vibration when starting in first gear and sometimes in second. Clutch pedal seems to be hard. My car is 21 months old and problem began at 24000 km. I don't know if there's someting wrong with the pressure plate and/or clutch bearing. I asked my dealer to test drive my car and they told me that everything was normal. I'm driving manual trans since i got my licences 23 years ago and never had problem like that. Am i the only one having that problem ?
