NHTSA complaint #10410127, filed 2011-06, 128,000 miles“My car completely turns off while im driving it, most of the time when I used it the first time of the day and try to used it again it turns of and loose power, I can't turn it on again in that moment I need to wait and then it works again but if happens really frequently and its really dangerous because im on the freeway and cars are behind me and I can cause an accident or anything worse. I went to the dealership so they could inspect my car but they couldn't find anything at that moment.”
NHTSA complaint #10683010, filed 2015-02, 89,400 miles“I have been taking my car to Kia of orange park in jacksonville, florida for the past several months because of issues with stalling and hestitation at start and the car has stopped on my while in gear with my foot on the brake (three or four times). Each and every time I take it to the dealership they seem to say the vehicle will not duplicate the concerns I am having. I have been afraid to go a long distance with the car because of these issues. …”
NHTSA complaint #10458921, filed 2012-05, 71,000 miles“The driver side door will not open. It shows that it's unlocked. I can use the key and continuously pull the handle from the outside and it was opening. Now it doesn't work at all. Took it to Kia in holland they quoted me a minimum of $300 to fix the problem but told me they had no clue what it could be. I will not allow an ignorant person to touch my vehicle. I can at least tell you that it is the latch. I live in michigan. If I am hit on my passenger side and am in need of help I might as well close my eyes and die. …”
NHTSA complaint #10683118, filed 2015-02, 134,000 miles“Driver side door does not open from inside, even when in 'unlock' position. I drove to work, having no problems opening the door to get into the car, nothing unusual happened during my 15 minute commute. I arrived at work, and was forced to exit the car through the passenger side door. The driver side door will now only open if you use the key and can randomly find the perfect timing of turning the key and pulling the door handle. It is nearly impossible to perform this maneuver from inside the vehicle. …”
