Oh no....I love this 09 Sport, While driving, at almost any speed, the car bucks. Not violently, but I have to feather the gas pedal then it clears up. Doesn't feel or sound like its from the engine, but rather from the trans ! The car has the 'Paddle Shiftier' (which I hate) and never use. Checked the trans dip stick and all is well (what color is the trans fluid)? I'm used to a red color but mine is almost clear. I had the trans fluid changed about 500 miles ago also. Any help???

 

Could very well be a missfire. Need to monitor cylinder misfire to isolate it cause.

 

Just experienced this with my 09 sport - The bucking/jerking was related to bad spark plugs and coil packs that caused my engine to misfire. There’s a lot of helpful threads on this here - seems to be a common issue.
