2018 KIA OPTIMA Complaints

The contact owns a 2018 Kia Optima. The contact stated that while driving 35 MPH after leaving the dealer, the vehicle started to overheat. The contact stated that the high engine temperature warning light was illuminated. The contact was able to safely pull over and turn the vehicle off. The contact restarted the vehicle and the engine temperature was still elevated. The contact stated that the vehicle stalled in the middle of the roadway. The vehicle was left on the side of the roadway. The vehicle was taken to the local dealer and diagnosed; however, the contact was not provided the diagnostic result. The contact was informed by the mechanic of an unspecified engine failure. The vehicle was not repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 77,200.

The headlights on my 2018 Kia Optima have been turning off and on randomly by themselves while in motion. Each time it's happened has been in different areas at different times of the night. The headlight switch is kept in the auto position most of the time. When the headlights turn off, the screen in the dash for the headlight function switches from auto to off by itself. Sometimes if the turn signal switch is jiggled the lights will come back on. Other times the headlight switch, located on the end of the turn signal switch, has to be turned to the on position to get the lights to turn on. The car has been in for service but each time the technician is unable to reproduce the fault. It is occurring more frequently and becoming a safety issue.

The electrical components connected to the headlights seem to be faulty. When lights are set to AUTO, the lights will turn off completely when switching on turn signal. At times the light will not come on at all when set to AUTO or On without cycle back to off.

The contact owns a 2018 Kia Optima. The contact stated that the vehicle was consuming an excessive amount of oil without warning. The contact stated that after receiving an oil change, the oil reservoir was empty within less than a week. The vehicle was taken to an independent mechanic where the oil change was performed and the mechanic diagnosed the vehicle with engine failure. The contact then took the vehicle to the dealer where she was informed that since she was the second owner of the vehicle, they could not offer any assistance. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 64,000.

When driving with headlights set to Auto the headlights turn off whenever the blinker is used. I've found many complaints however my vehicle has not been inspected. This poses a hazard of driving at night with no headlights, then having to fiddle with the switch to turn them back on.

I purchased my Kia optima brand new I believe it had 7 miles on it when I purchased it, shortly after it was purchased it started having a problem with the transmission, I would go to takeoff and it was lunch and jerk pretty hard to where it was very noticeable. I took it into the shop they thought that it was something a computer program could reset they performed that I did not fix it, I don’t drive my Kia very much I barely have 25,000 miles on it right now I am a real live in care provider so I don’t drive very much my job is at home. I have taken the car into several dealerships repeatedly to have it fixed, IA really was at a loss and did not know what to do because I had taken it to two different dealerships and the problem was never resolved. I contacted an attorney they got nowhere because apparently I needed to take my car in one more time within a timeframe for them to be able to do anything about it? And any right, still to this day the car does the same thing it’s been in the shop four or five times for this problem. One time I took it to Kia and Elk Grove they kept it looked at it said they couldn’t find the problem. Every time I’m renting a car paying for the insurance going through the inconvenience of renting a car paying extra insurance etc. just to have nothing done with my car. When I went to pick up my car from the Elk Grove dealership I threw a fit because I was tired of it and I said look somethings wrong with the car I’m not a mechanic I can’t tell you what it is but I need this car fixed, the service manager came out and said I’ll take a a ride with you and we’ll see if maybe I can see what the problem is we didn’t even get out of the parking lot and it jerked so hard at the service manager noted it in the file had me drop it back off and leave it it’s still wasn’t fixed. I took it in again after that the new service manager took it on an hour drive on the freeway hooked up to a computer with Kia and of course it didn’t do anything while h

We would like to know what Kia is planning to do to address the fact that Kia built a car without the basic immobilizer circuit making it very easy to steal. Over the last few months, local and national news reports, as well as many social media sites, have reported on this security flaw which likely emboldens others to attempt a theft of a Kia and/or Hyundai. As I do not live in Milwaulkee, I would like to know how the company will fix this problem for the rest of us. It will not be restricted to just one city. There are numerous articles by victims that have detailed how their car theft cost them thousands of dollars in insurance deductibles, rental cars, and repairs. Many of the articles explain how thieves as young as 12 years old are able to still these cars in under a minute in broad daylight and driving recklessly creating a serious safety hazzard. Please advise what Kia will do to negate this serious security flaw.

Turned on my car and steering wheel was stuck , it didn’t turn, turn the engine off and back on and it went back to normal.

while driving, all lights (headlights, instrument, etc) would randomly go dark. Lighting usually restored after toggling the instrument control arm from on-to-off-on. Obviously super dangerous as driver can't see roadway and other drivers can't see the car.

Vehicle is making a noise when trying to accelerate. Have replaced all spark plugs and coil #4. It is making noise still and shaking. Coil has been switched and issues are reading fuel injector or air intake or electrical. Previous reading was head gasket... Only on spark plug 4 coil is it reporting an issue...All dealerships locally are booked to even get a diagnostic test.
