Since 08/07/21 I-??ve been having intermittent issues with my oil light and engine light coming on. I have had all repairs recommended by the Mark KIA Scottsdale, AZ dealership yet my oil consumption has increased significantly and the oil light continues to come on: On 02/14/24 I took my car to a local auto repair shop to get a second opinion due to the oil light coming off and on; they found the engine oil very low and only 1 quart came out when doing the oil change; they also recommended injection induction service which I-??ve had done twice previously with the KIA dealership

2.4 motor burns excessive amount of oil, has a serious loss of power. The dealer informed me the only way to get a new motor or get it fixed is for motor to blow.

My 2016 kia optima shut off on me and would not start on December 20th 2023. I had the vehicle towed to bergeys kia and they looked at the vehicle and said that it was the engine and it would cost between $6,000-10,000 to replace the engine. The vehicle has never had any problems. I do not bring my car to kia for oil changes because it is really expensive so we do that at home and kia is telling me they can-??t fix my engine because I do not have a receipt of the maintenance. The engine has a recall and I was never notified about it. My vehicle was in their shop on September 6th 2023 and I was not notified then either. I am a single mother and I currently do not have a vehicle to take my son to and from school or to get to work. The engine is recalled so I think Kia needs to fix this.

While we were driving home (3 people in my car), with no notice, my car lost complete acceleration and broke down while we were on the highway. We hardly had notice to understand what was happening, let alone the other cars/people behind us on the highway where we almost got hit before being able to pull over to the side of the highway. We then had to wait for a tow-truck, again, on the shoulder of a very busy highway. Later, I came to find out that this was "sudden and unexpected engine failure" that occurs in multiple models of Kia and Hyundai that was included in the Hyundai and Kia Engine Litigation, Case No. 8:17-cv-00838, and Hyundai and Kia Engine Litigation II, No. 8:18-cv-02223-JLS-JDE, New Theta II Class Action Lawsuit. Unfortunately, this was the first time I had heard of this, as I'd never received any recalls or notices for my car around this, even though my car is a part of this. As I am in contact with Kia Customer Care attempting to resolve this issue - which has been an awful experience so far - they have informed me that the RECALL CAMPAIGN PI1802B - PI1802 ECU UPGRADE - is a "product improvement" instead of a safety issue, in which I COMPLETELY disagree! This put the 3 people inside my car at the time of the engine failure in danger on the highway with zero notice except for when it happened, as well as the other people/cars on the highway surrounding my car. Clearly this has been a much wider issue for Kia and Hyundai that has called for class action lawsuits, and my experience has been terrible so far trying to get this resolved. I'm extremely unhappy with their customer service and "help" this far, and even more upset that this did cause safety issues that it feels they don't care at all about correcting or taking care of their customers.

Engine light is blinking

- Indianapolis , IN, USA

My Kia Optima randomly stops working while driving. I get a notice that says, "HEV: Check Hybrid System. Stop Vehicle and Turn Off Engine." Also the gas pedal stops working, leaving me to try to coast to safety. The car essentially stops working in the middle of driving, without warning. Once this happened and blew out the spark plug, requiring a new one. Then, a day or two later, the car returns to normal. The Kia dealership could not reproduce the problem, nor could my service center. They say it's fine. I took my car in for previous recalls, and it is currently "up to date." This appears to be the same electrical issue as a recent recall for electrical failure, but the dealership told me the spark plug was fine and that I should change the battery. I did and this still happened. I do not feel safe driving this car, and Kia won't help me find the problem.

Loss of power. Was driving across a 4 lane intersection and the vehicle lost power. The engine light came on. I stopped and check the oil and it was 2 quarts low. We had just changed oil less than 2,000 mikes ago. I tool the car to parts store and they said it was a p0309 code. That #4 cylinder misfire. It was either coil or spark plug. I replaced both coil and spark plugs 15,000 miles ago. The plug was covered in oil had black oiley substance covered on the spark area. I had similar loss of power due to oil burning 15,000 miles ago. The car has 97,720. This is an ongoing safety issue.

- Grand Junction, CO, USA

Purchased this car in July of this year. I checked all fluids prior to purchase and after driving it for 30 days the oil light flicked then went off. I decided to check the oil and it was 2 quarts low. I immediately called my extended warranty and they said to take it to the shop. After it being there for 3 months they said it was the rings in the piston and it needed a new motor. They referred to it as excessive oil consumption. Of course the warranty company Old Republic refused to cover it because it-??s a on going issue with this model car.

Car is leaking oil. It is not only visible but I can smell it as well. Visibly it looks like its leaking onto the heat shield. This is very dangerous as heat shield gets extremely hot since it is over the exhaust. Also visible are the stains on my driveway. Additionally, I have been measuring oil levels and it is dropping slowly.
