I've noticed on numerous occasions that my 2009 Sierra Hybrid has problems finding the right gear when applying the accelerator from a dead stop. The truck starts to move but then you feel an abrupt and significaqnt lurch in momentum as it shifts from EV to gas. Is this normal? It reminds of the days when i was just learning to drive a stick shift. Not good.

I also have a hybrid and it has just started lurching. It does not do this all the time and of course it would not happen on a test drive with the mechanic. It happens at around 30 kph.
I have driven the Yukon Hvbrid and did not notice any "lurch" when the gas engine took over. I would think your local GMC dealer would be able to help you get to the bottom of this issue.
