| Description of the problem | I have found the traction control to be too drastic at times. When pulling on to a highway there is usually a small bump (difference in height, about 2", between the road and the parking area). If i'm accelerating (which you usually have to do to get onto a busy road), when the car goes over the "small bump" the traction control kicks in and the car loses a lot of the power you need to avoid the oncoming traffic. The traction control causes the car to come to a "rolling stop". This seems a little too extreme to me and i feel like this will cause an accident and potential loss of life. I have owned 4 other cars with traction control (2 saturns, 1 corvette, and a kia forte). None of the vehicles mention had an issue like this. Usually the traction control will "gradually" slow down the wheel or wheels that are turning faster than required. The optima almost comes to a complete stop, losing 95% of it's power on june 6, 2014 i returned the car to the dealer (fette kia). I was able to reproduce the problem and they said this was how the car was designed. The issue has occurred numerous times the date above was used to complete the form. |
