I just got my 2010 Lance Sportback GTS 2 weeks ago, and I'm a bit concerned. when I accelerate between 10 and 40 mph I can feel a slight "stutter" (this is the best term I can think of to explain, I can feel it gain power then lose power then gain in a rapid succession.) This is the first time I have drove a car with a CVT and wanted to check here to see if maybe I'm just feeling something normal. Its obviously still under warranty, I just don't want them trying to say its normal if its not.
