The vehicle doesn’t want to start anymore and the mobile mechanic said the engine had ti be replaced since it was off the timing loop. No engine or vehicle lights were in and no prior issues were appearing.

My engine failed on a busy road on my home after a long day of work. I was at a red light when my car failed and was terrified a car was going to hit me. I was the first car in line and had barely made it past the light. Thankfully, I was able to have my car pushed into a nearby lot by complete strangers. I had just gotten off of the freeway, I easily could have been killed or hurt. My car was towed to the dealership where I purchased it from where it was confirmed that my engine seized and I needed an engine replacement. My car started knocking the day before it failed (Friday, May 26, 2023). This is the only symptom my vehicle had. I took it to Kia the same day and they told me to return on Tuesday morning after the holiday weekend for a diagnosis. It failed Saturday afternoon (May 27, 2023). I have not had it inspected by KIA because they insist that they will not honor the lifetime warranty on my car because of a pre-requisite system update that was not completed. However, once again, the dealership I purchased it from has done a diagnosis and concluded that my engine seized due to faulty manufacturing. I am the second owner of the vehicle. The previous owner received both of the recall notifications in the mail regarding the system update that was required to be covered under the lifetime warranty. I knew nothing of it and Kia refuses to hold themselves liable for an engine that would have inevitably failed — and could’ve cost me my life.

Driving 2015 Kia Optima on expressway at night when car lost power and died. We almost got hit by cars and trucks trying to get over to side of road. Dash lights went crazy as did headlights and nothing worked. Had car towed to Kia dealership and they confirmed that engine locked up. Kia refused to cover because ksds updated (that we did not know about)was not done even though this engine is known to be manufactured faulty and are failing at astronomical rates. Kia knows they should be recalled. They refuse responsibility even after they settle lawsuit after lawsuit.

my car paint is chipping in multiple places around my car. This could lead to rusting witch, can ultimately lead the body of the car to be easily damaged. it will cause a weakened body structure which can lead to so many damages in the future. I am mediately contacted Kia corporate as soon as the problem got worse, they refuse to pay for my whole car to be repainted. I have a pearl white Kia car, which is known to chip and bubble up. to fix my issues immediately, I went to get my car painted at an affordable place with my own money.

We are a used vehicle dealer. We purchased this vehicle for resale from a new vehicle dealer, while transporting it back to our lot, the motor blew up. Kia is willing to fix it, but not while it is titled in our name. They will only repair if it is in a private individuals name. There is an issue with the vehicle and why will they only repair if it is titled to a private individual?

Driving on highway auto lost all drive power and stopped running. Zero warning or lights were ever noted on car and no vehicle function had been observed in previous days. Auto towed and mechanic checked vehicle. Found engine seized and unrepairable. Shop reviewed this as a known recall from previous models repaired. Kia contacted by owner, VIN reviewed and noted to be part of a class action suit as well as confirmation this malfunction was a recall. Told by Kia that recall would not be honored since this is a second owner. However we researched this and could not find any recalls prior to purchase of this vehicle. This malfunction could have resulted in accident, injury or death and we as owner were given no choice to repair or even identify this malfunctioning vehicle.

My air and heat stopped blowing air on 4 (high speed) I took to mechanic who couldn’t find a issue with the resistor, motor, or any components related to it so he took the dash off to check the climate control. The connector going into the back of the switch control to control the temperature speed was burnt and so was the unit. He said it was a wonder my car hadn’t caught on fire and it should have blown a fuse before burning that bad. I did get pics of the connector but didn’t of the control panel. I am now afraid to drive my vehicle as this is a expensive repair and their seems to be a lot of electrical issues with Kia from what I am finding and I don’t even have this vehicle paid for yet. They replaced a motor in December due to failed components on their end

Chunks of paint are coming off my car on the freeway. It was raining and a large section of paint flew off and onto the car that was driving behind me and stuck to their windshield. The occupant almost had a collision with another vehicle on the freeway. I was able to follow the car that got the paint stuck to their windshield and I did apologize and got their contact information to verify my incident.
