I brought my Kia optima sx in at Kia Atlanta South dealership for a Hydraulic electronic control Unit recall to be service since the problem can result in a engine fire while driving or parked but the dealership did not do the recalled service and told me that it was done. I checked my engine fuse to see if the new fuse were installed and new label was put on in place of old fuse label and none of it was done.
Steering, Feb 2, 2025
MY VEHICLE HAS 75,583. I received a recall for 3 items and made an appointment and took the car in for the work. I noticed that their wasa slight dead spot in the centeing of the steering and asked if there was any adjustmen. I was told there wasn't but they would check it because there was a known problem thith the plastic gear in the electric motor's connection to the rack that wears out and can completely disintegrate. when I picked up the vehicle they had obviously checked it because the slight dead spot had turned into a clunk. As there was no recall they would nothing about it as the vehicle was out of warranty (10 years, 100,000 miles). Had it had a higher annual mileage it would have been replaced under warranty. My concern is that this fault may be hidden by the warranty coverage. If the plastic gear fails completely the steering could become locked or inoperable. This is clearly a well known problem as there is a youtube video showing the replacement process. This actual mechanism may be used on several other years and models. The video is here: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Electrical system, Service brakes, Feb 1, 2025
The car instrument panel showed two messages "check brake " and also "hybrid system warning safely stop and do not drive" The brakes stopped working and the car will not accelerate. I stopped reset the battery and started the car as if nothing was wrong. this happens intermittently when i drive the car for over an hour. the brakes are brand new the brake cylinder is working fine. only when this warning come up the brakes feel like they are grinding. a lot of owners are complaining about this. I am wondering if there is a recall for this issue.
Engine, Jan 22, 2025
On the evening of December 5, 2024 my 2012 KIA OPTIMA's engine completely seized out of no where while traveling on a very busy road where the speed limit is 50mph putting my life and other drivers that share the roads life in danger. Thank god I was able to succesfully merge over into a safe place as the car came to a hault. Previous to this incident the car was running perfectly fine with no dash lights on what so ever. Once I was in a safe place I called KIA headquarters immediatly, I was told that I have to pay to have the vehicle towed to the nearest dealership and that I would be reinbursed depending on the issue of the vehicle after being diagnosed. The very next morning I called KIA corporate to open a case for the vehicle, in which i was told that my specific year, make and models engine was under a lifetime warranty. I then recieved a call from the dealership Decmember 6, 2024 and i was told my optima would be diagnosed and if the issue is due to the KIA engine class settlement that the engine would be replaced free of charge and if it is not then I would have to pay $380 to have the engine repaired under the lifetime warrantly & that the car could not be looked at until December 16, 2024. Once December 16, 2024 came around I recieved a call from the KIA dealership and I was told that my vehicle could not be diagnosed due to the time frame in which i bought the vehicle and that I needed to have my car moved from their lot or I would get charged $80 a day storage fee so I had to have my vehicle towed back to my home where it is currently just sitting. To this day (January 22, 2024 I am still dealing with trying to communicate with KIA CORPORATE AMERICA to have this matter resolved for I am very aware of the engine recall issue for my specific year make and model. My vehicle has yet to be inspected and the only time the warning lamps came on was once the engine completely seized, all of the dash lights popped on.

Engine, Jan 7, 2025
While driving 2012 Kia Optima GDI home from work, the power suddenly stopped without warning with the engine, oil, and battery lights flashing on all at once. I was unable to accelerate whatsoever, so with the momentum of the vehicle I parked safely in a parking lot. There I discovered the car would not start and would give a loud clunking sound. A mobile mechanic confirmed that the engine was seized, and I had it towed to the nearest KIA service center. They were able to also confirm it was an engine seize, but insisted KIA would not replace the engine despite a recall notice of the motor of this vehicles make and model in 2017 (SC147).
Exterior lighting, Dec 19, 2024
My 2012 Kia optima headlamps are extremely dim, even though I’ve replaced the lightbulbs with the highest possible lumens, multiple times, the headlamp assembly continues to dim. This requires that I ride with my high-beams on to drive at night. The lights have been dimming for more than 20,000 miles, but they are almost useless at this point.
Steering, Nov 29, 2024
The steering is making a clunking noise when backing up and going forward at low speed. There is a TSB by Kia about the steering motor rubber gear spacer that simply disintegrates over time but Kia is only performing repairs on vehicles in warm humid areas up to South Carolina. Why up to South Carolina? Being we live on the Eastern End of Long Island in Southampton Town in New York : we are surrounded by the Atlantic Ocean to the South and Long Island Sound to the North. On Long Island, the temperature frequently approaches 100 degrees in the summer and is very humid also. I would say we qualify for a recall based on what the TSB says. There should be a recall for every Kia Optima along the Coastal United States that has this issue as it could become quite dangerous. From what I have heard and seen on line , it is a multi hour repair for several hundred dollars. The NTSB should get a recall done not a TSB.

Engine, Aug 21, 2024
Driving on highway at about 60mph when the engine started knocking and the power decreased significantly. I pulled to the side of the road and called my day who came and brought his OBD 2 tester. The code was P1326 which is Knock Sensor. We had the car towed to a KIA dealer nearby and they updated the software. We picked up the car the next day. It seemed fine at first. Within two weeks the the same thing happened and we, once again had it towed to KIA. Within a few days, the service writer called and said that the engine needed to be replaced, but that KIA was denying an engine replacement. They said that they found sludge in the engine that in their opinion showed a lack of maintenance. We sent in receipts for oil changes every 5-6K miles. At this point, we do not have an answer regarding an engine replacement.

I started the car up no lights on, started fine, no warning symptoms like loss of power, no oil consumption nothing! Started an hour and a half drive to visit family and I started hearing a weird sound almost like plastic was flapping around on the bottom. Turned down the music and it was only making this weird sound every 5-10 seconds. Pulled off of the road shut the car off and checked under the hood, the oil everything seemed fine. Started it up and heard the sound again and suddenly became worse and came to the conclusion it’s a rod knock. Had to get off the busy road so continues for maybe 1 mile and every dash light came on shut it off waited for a trailer, once we got it on the trailer the lights were gone. The dealership near me is saying they can’t do anything due to a recall update not being done but I had a newly programmed ECU that was put in in March of 2023 and I was some research and i found a few things stating the ECU would be completely up to date but kia is fighting me on it. I have also been update to date on maintenance records. Since its been at the dealership I’ve asked for the other 2 recalls that are open on it to be done while I figure out what to do with it and they bypass me asking everytime.
