Lights appeared on the dash and the vehicle locked and would not drive. This happened as I was actively driving. I had the vehicle towed and was told by the Kia dealership that it was my abs/hecu. Before this happened, there was no warning lamps or messages. The car was driving normally.

My engine is burning oil at an alarming rate, my car is not recognizing low oil, so I no oil lights are appearing. I have to go to the oil change place weekly to have my oil checked. When my oil is low, I have to pay to have my oil replenished between months of my oil changes. My and my son safety was put at risk, when I found out at an oil change visit, I had less than an quart of oil I was driving around with. Which can cause engine failure while driving, overheating, and reduced performance while driving. This was confirmed by an oil change facility. I am currently in a ongoing dispute with the dealership I received my car from. The Kia dealership is refusing to do any maintenance until I can produce five years of oil change records that are not showing on car fax. To date my car oil light is not coming on, no signs are shown in my car showing this issue. I have to just get it checked weekly and pay for oil to be safe until, I can get a new engine.

I brought my Kia Optima into the dealership in October 0f 2024, because my airbag light came on. It has not been there over 6 months because my passenger airbag module is not operable and rending all my airbags useless; it is also on backorder with no ETA. The dealership wouldn't help with my escalation it has taken me 6 months to get to the escalations department and now they will not offer additional support with payments or a buy back "due to warranty". I feel helpless and like my investment has been thrown in the trash and lit on fire as my car is sitting in the parking lot in the AZ sun, not being moved and not protected from the elements. They continue to offer no real resolutions and tell me to wait for a piece that has absolutely no ETA.

Oil is getting into cylinders causing spark plugs to misfire. Very high oil consumption so I have to put oil in it every other day in between oil changes. I’ve been to Kia Service department several times in the past 2 months.

My 2019 Kia Optima purchased brand new. Kia released a service bulletin on 3/1/22 citing “excessive oil consumption for 2011-2021 Optima's”. I took it in for the "updates" for said service bulletin for the engine and was told that my engine is good and covered now for the life of the engine even past the 100k miles (mind you no one mentioned doing an excessive oil consumption test at this time). On 3/22/24 car had 104k miles on it and the oil light came on. I had an oil change just 2500 miles or so prior. Pulled into an autozone and it was almost bone dry. I put oil in it and the light went off. I took it to Evans Kia and was told that they couldn't do anything because it was past 100k warranty and that they couldn't run the DX test to determine if it was excessively consuming oil as per the recall. Apparently during the recall they did the DX tests if the consumer stated it was burning oil fast or something to that extent. Mine did not get said test, only the upgrade. They should have done the test, but they just did an "upgrade" which clearly did not work. They said since I had the "upgrade", if the engine fails, then Kia would fix it under warranty. Since then, this happened at least 4 more times with the oil light coming on and engine oil practically gone. Each time took less and less miles. I showed up to Kia 2 of those times in 2024 to show them the the oil change date, mileage, and check oil light on. Also physically showed them the oil being almost empty, yet they did nothing but say when the engine dies or "knocks" they can fix it under warranty. One of those times I had it towed but they determined it was the fuel pump, never mentioned anything else. Fast forward 3/15/25 the engine starts knocking and engine light comes on. I managed to drive it to Evans Kia without any accidents. After my car sat for 9 days, they call me on 3/25/25 and tell me there is a "burnt valve on cylinder 4 and the engine will need to be replaced and it is not covered. How? Help!

UNKNOWN. Vehicle is burning through oil every 1,000 miles or so. Excessive oil consumption which i am aware there is a recall. However Kia states my VIN # is not included. While at the dealer service department for failed A/C system, we questioned the excessive oil consumption and engine replacement. We were told they found nothing wrong. Having to top off oil every 1,000 miles or so. It does not make it to the next oil change before the light comes on. No oil leaks. Mechanic said known problem with this engine. Most recently the starter went bad, alternator, and battery. Replaced with a second brand new battery and car won't start again. Dash is lighting up erratically, new battery dead. As if something is drawing all power and draining brand new batteries. This car has a little over 86,000 miles and one thing after another is failing. The car lost power and power steering in a curve leaving us in a dangerous situation after replacing the starter. Dash lighting up erratically with front end collision warning message on the display. We had it towed to our residence which our auto insurance reimbursed us for. Replaced alternator and battery yesterday, and the car lost all power again turning back onto our street, again with the Dash lighting up erratically.

It was snowing and an icy day Jan. 21 in Atlanta, Georgia. I was driving on Buford Spring Connector going southbound. I was on a bridge and it was completely white and icy. I saw there was a car stopped in front of me. I tried to put on my breaks and my car would not slow down. I was getting closer to the other vehicle still trying to break. I tried to use my electronic emergency brake and it did not engage. The car did not even try to break for me which it normally does if I moving faster than a stopped car in front of me. I rear ended the person in front of me. I just wanted to let someone know as the forward collision did not work in this case and the accident could have been avoided.

On October 30th 2024, I purchased a 2019 Kia Optima from San Diego Chrysler Dodge Jeep Ram. On November 26th the car was stolen from in front of my house, while the alarm was activated and the key was in our possession. I went online to the Kia website to find some information and found that there was a recall on that vehicle to install an anti-theft device. San Diego Chrysler did not have this done. I contacted them in regards to that not being done and they replied that they offered me to purchase a GPS system. They don't seem to feel anything was done wrong but if a car has an open recall, it would seem that a dealer needs to have that done PRIOR to selling a car to a consumer who is unaware of the theft problem. I had the car for three weeks, lost my trade-in, deposit and still have it financed. Big conglomerates need to be held accountable.
