This pre-owned vehicle lost power at an intersection with my wife and child in the vehicle. Both of them were fearful and in tears. Several indicator lights suggested problems with the engine, HEV system, and battery. Upon returning home, I notified Carmax and scheduled the vehicle for service at a local Kia dealership. Although the mechanic told me that he knew there is a problem with the vehicle, Kia failed to diagnose or fix the problem(s), and could not assure me that the vehicle was safe to drive. Maxcare would not cover a rental car because no diagnosis was made. Kia also informed me of a previously undisclosed, long history of problems going back to 35 miles on the odometer. I requested a copy of Kia's vehicle history report and Kia refused to provide it. I also reported this safety concern to Kia Consumer Affairs, who provided no immediate solution, said they would contact the local Kia dealership, and referred me to an "ongoing" class action settlement at [XXX], which indicated that the settlement had closed on 8/9/21. Because no other option was offered to me, I was forced to pick up the vehicle from Kia. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

First I had an oil leak which I was advised to warm my car up to prevent from getting worse. At the time I was told it was minor. Then my oil light started coming up every 2 weeks and when checked there was no oil. Now 2 months later, my car has stopped and showed a blinking check engine light. When checked I was told a code of p1326 which is the knock sensor. I have only had my car 7 months and it-??s been problem after problem. Not to mention only a month after buying it was stolen. Due to no immobilizer So I-??m sure a lot of the issues are also a result of the dumb theif who decided to damage my car. Also my cruise control doesn-??t work a lot of the time.

KIA states they are unable to provide the vehicle with the anti theft software update due to the vehicle having a remote start. I asked if they can remove the remote start. KIAs are not safe with only using the Club steering wheel lock. Theives are drilling a hole through the keyhole or cutting them off. My car is now worth less & auto insurance is becoming more difficult. Please make them do something! These cars are still getting stolen nonstop every single day!

I was driving with an SUV in front of me at 18-wheeler in front of them. This is on a road where the speed limit is 65 however there's a section on 301 where there's a traffic light. All three vehicles came to a slow normal stop and the adaptive cruise control was doing a good job of slowing the vehicle down without my input. But the SUV when we were at about stopping speed but had not yet come to a complete stop, the SUV switched to the left lane. At which point I was maybe 20 ft behind the 18-wheeler and all of a sudden the car is adaptive cruise control tried to accelerate the car back up to the setting of 65. It didn't register the 18-wheeler at all It just registered that the car in front of me had cleared the space and if I had not been paying attention and immediately applied the brakes to stop the car manually It absolutely would have accelerated directly into the back of the 18-wheeler. I was maybe 5 ft and it was still accelerating when I slammed on the brakes. I've been able to since reproduce the effects, it doesn't register 18 wheelers correctly in this specific situation as vehicles. I've even had the camera recalibrated in between tests. I have everything on video but unfortunately do not have access to the car's computer logs. I would be willing to send in my ECU for whatever is needed to identify this further.

While driving on the freeway and NO vehicles around me, the sunroof shattered, I am reaching out to consumers to see if they have encountered the same problem. As I reached out to KIA consumers affairs and after waiting 2 months I was told to reported it to my insurance and they will cover my deductible but it will take 90 days for my deductible to be processed and issued to me. A total of 5 months to wait for my sunroof to be fixed is unacceptable. FYI - KIA Dept. of consumers affairs (800) 333-4542 you will be on hold for hours before someone can help you, so annoying-?? Any suggestions or help will be greatly appreciate.

There is a viral trend spreading throughout the country that shows how easy it is to steal a key-start Kia or Hyundai. The perpetrators bashed my back rear window, dislodged the undercarriage of the steering wheel, and used something as simple as a USB cable to turn a knob and start the ignition. My safety was put at risk as well as others because these people that stole my car clearly do not care about their own life or others. No one steals a car for a positive reason. They drove it recklessly and abandoned it without concern for anyone. Kia and Hyundai need to address this issue or more and more of them are going to continue to get stolen and people are going to continue to get hurt, both physically and financially.

Engine is consuming excessive oil. That could cause internal parts of the engine to wear faster because of less lubrication and could lead to an engine failure while driving, which could lead to engine stopping and loss of propulsion which could cause an accident. The car went through a oil consumption test with a Kia dealership and failed by consuming more than 1 qt of oil in a 1000 miles interval. The Kia dealership proceeded to do a combustion chamber cleaning procedure and re-did oil consumption test and it failed again. They also had requested service record which where provided. Even though Kia has a service bulletin on that matter, the service advisor at the Kia dealership said that the manufacturer declined the claim. Right now I-??m constantly refilling oil in the engine which is also an additional expense. The first time I noticed the issue was in February, 2022 when the low oil pressure alert came on.

Since I purchased the car I have a had a issue with my vehicle misfiring. We purchased the car in 2018 and a few months in I had to bring the car in for a rattle and shaking while I was driving. It would give me a warning lamp stating that a -??possible engine control issue had been found-??. Since then I have taken the car in for the same issue three different time. Including the misfire and coil pack and spark plug replacement that I just had to pay nearly 600 for at the dealership. I have had this issue occur multiple time since we purchased the car and while driving on the freeway nearly putting my life at risk. This is an issue that needs to be addressed.

Several weeks ago, we had trouble opening and closing the trunk of our 2017 KIA Optima. Then a few weeks ago, the trunk of our KIA Optima closed and would not open at all. Because of the pandemic, we didn't contact KIA. But today, 16 Dec. 2021, as my wife was driving north in heavy traffic on US Highway 25 in Albuquerque, NM, the trunk suddenly opened and blocked her view of the cars behind her. Luckily she was in the right lane and was able to exit the highway. Otherwise there might have been a serious accident. We bought the car in 2017 from Fiesta KIA in Albuquerque, NM (505-999-2745). They have been unresponsive.

During the week of November 14th, 2021, I noticed my vehicle begin to noticeably vibrate and generate an unfamiliar sound near the engine compartment. The vibration and sound was accompanied by a "check engine" light illuminating. I immediately scheduled an appointment at my local dealership and was provided a date of November 29, 2021. On November 29, 2021, I dropped off my vehicle at the dealership and learned of NHTSA Recall Number "21V844." The service representative and his technician believe the vibration and sound are a result of the recall. To date, my vehicle remains at the dealership and the matter is unresolved. The service representative has advised me that Techline / KIA Corp. is determining whether my vehicle's engine issue is due to the recall or not. It has been two weeks that the vehicle has been at the service center. As per the recall notice I received in the mail, the inspection for the recall should have been completed in a matter of hours. I reasonably believe that Techline / KIA Corp is searching for an excuse to not remedy my vehicle's engine issue, and are jeopardizing the safety of myself and my family. I have a newborn and kindergartener that I have in the car daily and am concern for their safety if the engine issue does not get fixed. I am a military veteran and active police officer. I appreciate any assistance you may provide and thank you in advance.

While driving on an interstate on-ramp, I heard a loud bang from under my hood. I exited to the shoulder and as soon as I stopped, I heard a second, larger bang from the same area. Within a few seconds, flames started coming out of the engine compartment and began to fill the cabin of my vehicle from the area of the air vents and all through the dash. Within five minutes, the vehicle was fully engulfed in flames. I had no problems with the vehicle up to this point and the maintenance was up to date.

The wiring harness was replaced in my 2017 Kia Optima in 2019 at approximately 45,000 miles. Kia replaced my engine January 2020 because it was consuming large amounts of oil. I just got my car back in January 28, 2021 with a supposedly new engine. On March 3, 2021, my car caught fire while pulling out of my neighborhood actually driving down the street. Smoke and flames were coming out from underneath the hood the of the car. The entire front end of the car burned. Thankfully, the fire department got the fire out and no one was injured.
