I actually have a couple of problems with my CVT, and I hope that these problems are unique to my car and not common to all CVT vehicles:

1. If I come to a stop very slowly with very little brake pressure, at a certain point, about 10km/h or so, the engine/transmission seem to just cut off power to the wheels, so the car will jerk to a stop.

2. If I'm at a complete stop and need to get going quickly (making a turn across the oncoming lanes, for example), the car hesitates unless I take my foot completely off the brake for a full second or more before pressing the gas pedal.

3. When I floor it, the RPMs don't go up to the point of maximum power right away. Instead, the engine slowly revs up until it gets to that point, then stays there. Shouldn't the engine go straight up to the RPMs for maximum power when I throw my foot down? (I don't have an RPM gauge, just going off the sound of the engine and the feel of acceleration)

These problems really make my Vitz undriveable in certain situations. In many instances where I would easily be able to get through traffic in any of the previous cars I've owned, the Vitz just can't handle it, and I often end up sitting at intersections until the light turns red and I get the green arrow, probably pissing off the drivers behind me. I'm also considering buying a Lexus HS250h for my next car, which also has a CVT, so I'm worried that it will exhibit the same driveability problems as my Vitz. Is the Vitz CVT the issue? Should I have it checked out by Toyota? Or should I avoid CVTs in the future and stick with manual gear boxes? Thanks ahead for any advice.
