“Car will not always start. Sometimes I have to wait 24 hours and pick up the car wherever I had to leave it cause it wouldn't start. When trying to start there's a clicking sound and all panel light start to flash. Replaced alternator and battery, still not fixed. Seen a lot of reviews complaining about the exact some problem.”
NHTSA complaint #11254209, filed 2019-09, 153,000 miles“We bought our Kia with less then 10 miles on it, right off the show room floor, we have had to replace passenger side headlamps (total to date 5/15/2015) 15 times, both rear turn signals bulbs and rear brake lights. The air bag light would appear on the dashboard when ever the passenger seat would be moved and now the air bag light on the dashboard flickered driving home from work last night and remands on.”
NHTSA complaint #10588564, filed 2014-05, 500 miles“Keyless entry on driverside only locked me in and out of the car. Lock will only open 1/2 of the way. Airbag light came on and will not go off. I can not get an inspection. They say the system is unstable. Transmission has slipped a couple of times.”
NHTSA complaint #10556193, filed 2013-12, 80,000 miles“A co-worker followed me home and told me my right rear brake light was out. Then my right turn signal indicator on the dash started flashing real fast. Few days later my dash lights started flashing on & off. Had a friend watch the exterior lights and he said they were flashing on & off with the dash. Said he had never seen anything like that! If my headlights are on the lights don't flash. Even though my lights come on, the brake & signal lights don't work when I apply them. I have not driven my car because of it. …”
NHTSA complaint #10462902, filed 2012-06, 23,269 miles“I brought two new 2006.5 Kia optimas (a red one and a black one) from our local dealer. Since I have had the cars, both of the vehicles have had electrical problems which started within a few months of the purchase. The tail lamps only last about 2-3 months before I have to replace the bulbs. First one side or the other will blow out, and then within weeks, the other side will go too. This has been happening with both cars ever since we bought the cars. When I call the dealer and ask about the problem, they just tell me I've been buying cheap bulbs. …”
