I started to notice the problem climbing a hill. The transmission went nuts!!! It shifted from a gear to another. The RPM went at 6500 with no power on the weels. Later during the same day, I was at 90 km/h the pedal on the floor and the speed was not going up.... I went at the dealer today and they couldn't find the problem... Now I have a big problem because there is a problem... I am almost scared of driving the car!!!

Update from Jun 14, 2010: I went at the dealer the day after, the mechanic was in the car with me and he saw and lived the problem with me!!! They kept the car at the dealer and called me 3 days later. They changed the transmission to a brand new one. The car is still under warranty so there was no charge. I drove the car today and the transmission is working much better now. Let's hope they solve the problem for good... When I asked what could be the cause of that problem, they told me it is a problem in the transmission and I should live that problem with the new transmission.

Overall, I had a good service for now at the dealer!!
