Well, I've not been fortunate enough to convince Garve Hyundai until yesterday on my clutch hardening and poor gear shift issues with my 3 month old Grand i10, I had 2 unscheduled visits in last one month as I was invited by them responding to a COMPLAINT I raised @CSR, impact of complaint @CSR is grand which I suspect being a new customer I am honored with and god knows after a year or so would it still work. I am now assured reading your post Nitinmehta that HASS have weak hearing abilities and right I would suggest them to get machines helping them. In my case the issues are intermittent, my bad luck, If you start the car and drive it on smooth pitch for 20 KMs you will prove me wrong or may even recommend some driving schools,
BUT the moment you stuck in B2B traffic and frequent use of gear change and bite point on clutch, the car begins fighting with driver, gears will not settle into slot, and make various sounds (springs / Hiss / thud etc) clutch will become hard enough to make you stand on it, same thing happens when you drive it in top gear with full throttle or on very bad roads in 1st gear.
to resolve this you have to give a break , stop the car , turn off and wait and restart and all these issues will disappear...!! God knows what goes wrong. my complaint is escalated twice, last time the Hyundai Service manager himself drove it and found nothing wrong and I'm again invited HASS this weekend let's test the luck
