For model year 2011 Sedona vehicles, Kia will instruct dealers to verify the ACU part number and, if necessary, install an extension wire harness kit between the ACU Connector and the Vehicle Harness Connector.

MDPS Flex Coupling for steering needs replacement. Not covered by the 10 year warranty because it was 6 months late
Air bags, Jun 23, 2022
I took my car in for the air bag recall in 2018. When I picked up my car the air bag light was on. I called the Kia service line and they told me the light should go off on its on. So I drove home. I drove to work and back home and the light was still on. So I called the Kia service again and they told me to bring in the vehicle which I did. They checked and told me that they had no way of turning off the light. So I just drove home thinking everything was ok. Fast forward 2022, I had a seperate problem that forced me to take my car back to the kia service shop. They checked things in my car and I was shocked to learn that my air bag would not work in case I was in an accident. I told them this light has been on since after they did the air bag recall work but I did not feel supported here. the price tag to fix it is $1470.65. I feel that I am being treated wrong here because their initial work caused this light to turn on and they told me it was not related but now this vehicle check says it is a big concern if it is not fixed. I drive my three children to school in this vehicle. I am afraid for them and myself. I don't know what to do. This was part of the air bag recall and they caused this light to turn on and they need to fix it for me.

I was driving my 2012 dia optima approximately 55 mph and without warning the engine died killing power to steering and brakes.....tried starting it back up heard the fuel pump kick on good ground all the basics then I began to google possible issues and saw there were serious engine issues where the car either spews high pressure gas and potentially catches fire or bearing wear where the engine will shut off without warning.....I typed vin in said my vehicle was part of the theta II GDI engine recall so I called the 800 number where they told me that there were 2 recalls that needed to be done "before" the engine fails and that my vehicle had only had one of the two so I would have to pay to have it towed (315$) to local dealership to have diagnosed and tech line opened. I dropped it off on Saturday the 28th of may and was told due to holiday weekend it would be Tuesday the 2nd they would call well finally yesterday june 15th they finally called and the fella told us it wasn't covered and it would cost 8000$ for them to put an engine in or I could sell it to them for 300 or 400$. I called corporate immediately after speaking with ole dude the lady asked what the diagnostic came up with because my car is covered under lifetime warranty for the bearing issue in fact and doesn't matter about the fuel issue. She seems to think that he never even put on diagnostic machine she tried calling him 4 times from headquarters and was ignored each time. They never tried contacting me which was a registered owner or my wife who is now and even as far back as my little brother who I bought the car off of it was still registered in original owners and according to what I read they were supposed to actively seek out vehicle owners through registration etc because of danger and then in my opinion dude tried to hustle me knowing the car was actually covered telling me no and giving 400 then turn it in get new motor and make 10k....I did not smell fuel when I popped hood so I know
Engine, Jun 15, 2022
My engine seized up while driving with no warning or prior issues. My safety was put at risk because this happen while I was driving down a public road and could have gotten into an accident due to the cars malfunction. Kia has inspected the car but has refused to reimburse me for their engine failure although they had recall campaign for my model vehicle and other models of Kia vehicles. The only warning I was given was right before the engine failed the car said "hybrid system failure, do not drive"

I had went out of town and when driving back home the car start stalling and I pulled over to the side of the road. I tried to start it again but it wouldn’t start. After waiting on the side of the road for two hours I got the car pulled to a car shop. After they checked it the man told me that my motor was gone and I would have to get another one. I had called the Kia place about the recalls 3 weeks earlier and I haven’t heard back from them.

Several areas on my vehicle the paint is chipping in large chunks. The paint is not fading but coming off. I enquired to the dealership about this years ago but they said it was not in warranty for that anymore. The only reason im enquiring about it now is because I see many vehicles (kia optima in pearl white) on the road with the similar issue as me.

Engine, Fuel/propulsion system, Apr 18, 2022
Engine replaced under the recall campaign after failure and have had issues since with the car wanting to start. Turns over several times before finally getting it to start. Fuel pump and fuel line replaced out of pocket as well as a sensor out of pocket and still having the same issues intermittently then today while driving approximately 35 to 40 MPH the car just shuts off in the middle of the highway in morning traffic and almost caused an accident, without warning. Still took several times to crank before car finally restarted and made it maybe 4 miles before shutting off again while driving without warning and then smelled as if something was burning. Car has had scheduled maintenance as advised by KIA for warranty on motor but if something is not done about all of these same complaints then someone is going to get killed. Very unsafe!

A few months ago the paint on my car begin to bubble, chip, and peel away. The paint color is Snow white and I have been informed of and read a lot about de-lamination occurring in the pearl and snow white paint of some Kia models. The car has not been involved any accidents and is in great condition aside from the unknown cause of the paint chipping.

My engine failed. Dick Withams here in Waterloo, IA was paid by Kia to replace engine for free due to my warranty. Dick Withams rushed the process and allowed me back on the road with no coolant plug( which was detected immediately) I returned the car and Dick Withams attached a plug so my coolant wouldn't spill over on the ground. Every time I pressed my brakes THERE WAS A HORRIBLE SOUND LIKE MY DRIVE AXIAL WAS NOT PUT TOGETHER WHEN Putting the engine back. Kia is allowing Mechanics to fix these recalls of MAJOR SAFETY ISSUES FOR myself and my family. I then returned vehicle to Cedar Falls, IA Dick Withams to fix issue Friday morning. They have yet to communicate anything with me. Now I'm just without a vehicle even though it's covered under warranty. It should be against the law for the car dealership to return a recalled engine without driving the car to see if they rushed the service and failed to put vehicle back together CORRECTLY.
