What owners wrote

Upon acceleration, usually from a complete stop such as accelerating from a stop sign or on a green light, it feels as though the gears do no catch & the car jerks and the rpm's raise but the car stops accelerating. Will also have a "stuttering" or "jerking" while at a complete stop with break pedal being pressed down.
