On November 24th, 2021 I was merging onto a busy expressway when everything on my dashboard started flashing and the car shut down. There was absolutely no warning that the engine had no oil. No smell, no engine knocking sounds, no oil low light, no check engine light prior too it happening. It was towed to the nearest mechanic and they confirmed the engine was locked up. There was absolutely no oil in the reservoir per the mechanic. The oil was changed by Big O Tires on September 4th, 2021 and wasn't due for an oil change until December 4th, 2021. I searched my VIN and realized there was an engine recall on my 2015 KIA OPTIMA. I contacted three different dealerships near me to see who could look at it. I had it towed to the dealership and it was confirmed that the engine was locked up. It was apart of the recall- however KIA consumer affairs' denied replacing my engine for free. They stated that I hadn't had the product improvements completed on the engine since the recall was issued. I was never contacted by anyone from KIA of the recall on the engine. They had an old address on file which is possibly why I never knew. Kia Consumer Affairs said there was absolutely nothing they could do. The rules are very cut and dry- no exceptions. Kia dealership offered to replace my engine for $7,705. I declined.

Our car began making noise Wednesday, we took it to mechanic who says there's internal engine knock, and engine may need to be rebuilt or replaced. The issue is consistent with Kia's recent billion-dollar class action settlement, where engines were prone to failure fire. The class action claims window is closed. I don't want money, I just want the car fixed. I cannot afford this repair, nor should I have to for a car with under 60k miles. (Kia says it's not under warranty as we're the 2nd owner) I'm looking for any help or guidance for Kia to honor their obligation to repair dangerous vehicles.

I was driving my car and was hearing a clicking/thumping sound, until I turned left into a street where the motor just started shaking and making a louder noise. I started to press on the brakes because the sound and feeling of the car was very unusual. I came to a complete stop and put my car in park and waited where finally the engine just cut off even though the lights stayed on. I turned my key back to turn of the car and tried to turn it back on but my motor would just shake and my car would not turn on. i stepped outside and noticed there was oil spilling from under my car. I got it towed to a mechanic where they informed me my rod bearing came lose and punctured a hole in my engine. I called the KIA assistance center and said this was due to the recall SC212, but when i called a KIA dealership they said they could not cover the damage. Turns out this issue was part of a product improvement campaign which KIA would update the ECU in my vehicle.

- Derby, KS, USA

I was driving on the highway going about 55 miles per hour when suddenly the dashboard lights illuminated and car seemed to power down quickly. I barely had time to pull over to the shoulder of the road when the car completely shut down. I could not get the car to start backup and I had to call a towing company to the scene to tow the car to the Kia dealership. My safety and the other occupants safety were put in grave danger, especially driving on a highway where the speed limit is minimum 55 miles per hour. The car dealership confirmed the problem with me, but there is a significant wait time of 2 weeks or more before they can begin performing necessary repairs to the vehicle. Their excuse was an abnormally high number of other Kia Optimas ahead of my vehicle, waiting on parts from Korea, and the warehouse being backup due to the parts shortage. There were no warning lamps or noises prior to the car completely shutting down while driving 55 miles per hour on the highway. It was sudden and caught me off guard and I tried not to panic during the entire dangerous and scary situation. I have been without a replacement vehicle for over two weeks because you cannot get the rental/loaner coverage until the car has been formally diagnosed by a technician. I am paying out-of-pocket until I get the rental car coverage that Kia told me I would qualify for once the car is officially diagnosed and a timeframe is given for estimated date of full repair and pick up of the vehicle.
