| Description of the problem | Intermittently car will shudder (jerk forward and slow, jerk forward and slow) many times when accelerating, either from a stop or while accelerating from low speeds (less than 45mph) it seems possible gear changing is not smooth. And can be dangerous when attempting to merge into traffic as car does not accelerate as it should. Have taken the car to kia who report that nothing was wrong with car when they test drove it. Problem seems worse when it is hot or cold outside. |
