Hi to all, I have a problem where every once in a while at a stop light the first gear wont go in. I have to uncluch, cluch it again and then it will go in gear, sometimes going into neutral w/o unclutching wont fix it do it either the trick is that you have to unclutch and then try again.

Also sometimes the shifting feels rough where I can feel the gears while shifting in first second and third, and sometimes it will feel smooth as silk specially if I shift with a bit of a pause in between pressing the clutch, pause, then shift...

has anyone experienced this?

does it sound as if I should take the car to the dealership to get the transmission or clutch fixed?

Otherwise the car is AWESOME and I love it. Biggest bang for your buck.

 

I had the same issue. I went to the dealer (here in BC) and I was told there was no service bullitin for it. I learned afterwards there were plenty of owners with the same problem.

I did the same thing you did in terms of clutch action. What I do now is simply place it in 2nd and then first-works virtually all the time.

If anyone knows of a recall or "what trigger words" to use at the delaership, both of us are all ears.

Red Cell.
