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.

Back in September of 2020, my car randomly went to limp mode while driving at highway speeds. Had the car towed to the dealer. Dealer advised of apparent -??software issue-?? to correct the problem. Well this happened two more times after that twice the software was updated which didn-??t work. The third time the replaced the knock sensor and so far I haven-??t went to limp mode, however, the car has not drove the same and seems to get worse each passing day. Rough shifting, engine vibrates more than usual. Car struggles at times to go up hills, when giving gas a though way speed the car has a few second delay. Sometimes it feels as if the transmission is skipping. The car is up to date on all recommended services, I.e transmission flush and fill etc. There are also times when the vehicle is started but struggles. Almost as if it want to loose power but it doesn-??t. Has happened numerous times however recently it actually didn-??t start. Struggle to turn over a couple time but then finally did. A check engine light came on but then went away the next day after driving. I have an appointment with the dealer this week to look at this and other issues, again, hoping for some progress at that point.

When driving this vehicle rattles and shakes it has a burning smell/gas smell. It cuts off while driving. Looses oil.oil at low level before due. This make and model is no longer being manufactured. It has a known history of engine problems. Why were consumers allowed to buy this car. Problems are active and ongoing. Started about a year or close to a year after purchase. It is a lemon. The dealer wants to diagnose the engine, but they already know the engine is no good.

I originally leased my 2018 Optima with 98 miles on it and bought it out at the end of my lease this was my second Optima, I also had 2 Hyundai sonatas. Since I'm in sales I had the added mileage on it. At 98,000 miles the engine started ticking. I originally had a 2013 Hyundai sonata that when it hit 105,000 started ticking only to find that it was burning oil (1.5 quarts a week) so I was hesitant about another Kia but the dealer assured me that Kia had been aware of the problem and that they had fixed it. Guess what?! it hasn't. I took my vehicle in every 1,000 miles for oil change and have the documents showing how much oil was being burned off. According to Kia corporate there is nothing wrong even though my vehicle requires a quart of oil every 1,000 miles and was under owners warranty. Never again. People watch your vehicles. This is a know problem with Kia and Hyundai and they do not honor their warranties.

I was told by the dealership that my 2018 Kia Optima phev was repaired but after I drove it off the lot and got on the freeway the warning light came on again and lost all power. I almost got into another accident because of this. The dealership said they worked with Kia technical support to fix my car but apparently Kia doesn't know what's wrong with their own car. The vehicle has only 19K miles. I'm afraid for my safety and my families that this will continue to happen.

When I was driving on the highway on 2/14/2011 a "check hybrid system" warning came on, check engine light, triangle hev light, a red battery light came on and car lost engine power. After my vehicle slowed traffic down due to not having power I was barely able to pull over to the side of the road by coasting the car to the shoulder. It would not accelerate what so ever not even with just the engine power. When I pulled over the big check hybrid system warning dissapeared and only the check engine light and triangle hev light stayed on. I had my children in the car and almost caused an accident. It was towed to my home and after I connected it to the wall plug for an hour the lights dissapeared. I'm afraid that if I take the car to the dealership that they wont be able to replicate this issue since the warning lights are no longer on and they tell me they cant find the issue and this happens again in the future. There are several forums where people have this same issue from 2014 hybrid models and up and has happened to them numerous times and the dealership tells them they cant duplicate the problem.

I have never had any issues with my car, I get maintenance as scheduled so it's odd that this is even happening. On December 6th I went to move my car. I crank the car with no problem. I noticed it kind of hesistated slightly, but continued on with no problem. When I went to put my car in reverse in order to park it stalled and about 5 or 6 of the lights on the dash came on, the steering wheel went hard to manage/steer and as 6 other lights started blinking, I could no longer manipulate my wheel so I allowed the car to roll into the spot because I was on a slight incline and put it in park. The moment I did that the car cut off. It would not turn over, it would not do anything besides click when I tried to crank the car again. I eventually asked someone for a jump and managed to make it home. The next day I got up and drove as I normally would and thats when the eletric power steering warning light came on. When that light comes on the car becomes hard to maneuver. Thankfully that time it went off and proceeded to drive as it would normally. This issue happens unexpectedly without any warning. So at any moment I could be driving and the car can stop on me. I have 4 kids and live in a really busy area so even the thought of this happening has me second thinking each time I have to move my car!! I've seen more than one of the same complaint and I notice our VIN #'s are similar so something should really be done about this as it seems this is a trend with the year, make, and model of this car.

I purchased a brand new 2018 Kia Optima in November 2018. I have put approximately 22,500 miles on it and have been keeping up with updated oil change maintenance per the schedule recommended by the dealer. On Saturday 9/28 I dropped the car off for a routine oil change, and as I drove it off the lot it sputtered as if it was going to die, but it didn't. the car continued to run and it got me home. The next day, Sunday 9/29, it drove without problems for about an hour, but while driving the car completely powered down and stopped working. It was a terrifying experience as I was in the middle of a major city road and almost caused a serious accident. I put the car into park and was able to start it back up, and I was lucky enough not to be struck by another vehicle. The dealership was closed at this time so I called them first thing Monday 10/1 to report the issue and dropped it off. The dealership is claiming to be unable to recreate the issue so ready to give me the car back. This is a huge safety concern and I can't believe we as consumers have to put our lives at risk to wait for the problem to happen again before any recourse can be taken. From my research on the internet, it is very common for the dealership not to be able to recreate the problem so unable to provide a fix. Kia had 5+ years of engine stall problems that were not acknowledged until many years later, and the dealership certainly will not validate this. Furthermore, when the engine stalls, the power steering and brakes both go out, so you have nothing but prayers to rely on to keep you alive.
